Two sets of short bristles with darkened tips next to fontanelle. Measurements given in Table 2. Biological notes. Rhynchotermes diphyes has also been observed occupying abandoned termite nests (Cancello 1997) as well as the bulbs of banana plants and cattle dung. Comparisons. Mathews (1977) stated that the distinguishing features between the minor soldiers of R. diphyes and R. nyctobius were the curvature near the frontal tube tip of R. nyctobius and fewer bristles on head capsule of R. diphyes. However, after examining numerous samples, we were not able to confirm these differences as these characters are highly variable within and between samples such that it is impossible to separate the minor soldiers of the two species. On the other hand, the major soldier of R. diphyes has a large head capsule and a shorter, conical frontal tube whilst in other species (except R. bulbinasus which is bulbous) the frontal tube is equal or greater in length to the head capsule.

The Mid-Infrared Spectral Energy Distribution, Surface Brightness, and Color Profiles in Elliptical Galaxies
No full textWe combine 2MASS data and Spitzer archival data to study the emission in mid-infrared passbands (1.2Y24 m)
from a sample of 18 elliptical galaxies. In general the surface brightness distributions resemble de Vaucouleurs pro-
files, indicating that most of the emission arises from the photospheres or circumstellar regions of red giant stars. The
spectral energy distribution peaks near the H band at 1.6 m. The half-light or effective radius has a pronounced minimum
near the K band (2.15 m) with a second, less consistent minimum in the 24 m passband. All sample-averaged
radial color profiles hki kji, where ki < kj (and j 61⁄4 24 m), have positive slopes within about twice the (K-band)
effective radius. Evidently this variation arises because of an increase in stellar metallicity toward the galactic cores.
Color profiles hK ji all have positive slopes, particularly when j 1⁄4 5:8 m, although no obvious absorption feature
is observed in spectra of elliptical galaxies near 5.8 m. This, and the minimum in Re, suggests that the K band may be
anomalously luminous in metal-rich stars in galaxy cores. Unusual radial color profiles involving the 24 m passband
may suggest that some 24 m emission comes from interstellar not circumstellar dust grains
The Ages of Elliptical Galaxies from Mid-Infrared Emission
No full textThe mid-infrared (10–20 m) luminosity of elliptical galaxies is dominated by the integrated emission from
circumstellar dust in red giant stars. As a single stellar population evolves, the rate of dusty mass loss from red giant
stars decreases with time, so the mid-infrared luminosity should also decline with stellar age. To seek such a
correlation, we have used archival Infrared Space Observatory (ISO) observations to determine surface brightness
profiles and central fluxes at 15 m in 17 early-type galaxies for which stellar ages have been determined from
optical spectral indices. The radial surface brightness distributions at 15 m generally follow the stellar de Vaucouleurs
profile, as expected. We find that the surface brightness ratio 15 m=I band is systematically higher in
elliptical galaxies with ages P5 Gyr and in galaxies that exhibit evidence of recent mergers. Within the accuracy
of our observations, 15 m=I band shows no age dependence for ages k5 Gyr. The corresponding flux ratios
F15 m=FI band within apertures scaled to the effective radius (Re=8) are proportional to the 15 m=I band ratios at
larger galactic radii, indicating that no 15 m emission is detected from central dust clouds visible in optical images
in some of our sample galaxies. Emission at 15 m is observed in noncentral massive clouds of dust and cold gas in
NGC 1316, an elliptical galaxy that is thought to have had a recent merger. Recent Spitzer Space Telescope data also
indicate the presence of polycyclic aromatic hydrocarbon (PAH ) emission at 8 m. Several ellipticals have extended
regions of 15 m emission that have no obvious counterparts at other frequencies

The type bears, in addition to an original label and Mathews and Rothschild type labels, a ‘‘Figured’’ label which indicates that it was the model for Mathews (1924: pl. 513, upper fig., opp. p. 283, text p. 284) where the figured specimen was said to be the type of <i>alisteri</i>, thus confirming it as the type. The Rothschild type label is annotated with Mathews’ catalog number, although that was not given in the description, and opposite 3012 in his catalog Mathews has written ‘‘ Type of alisteri.’’ A second specimen of <i>alisteri</i>, AMNH 691702, collected by Campbell on 12 November 1902, was never in the Mathews Collection. Campbell (1903) wrote a report on the birds of King Island but did not say how many specimens he collected.</p> <p> Salomonsen (1967: 397) recognized <i>alisteri</i> as a subspecies of <i>M. affinis</i>; Schodde and Mason (1999: 286) and Higgins et al.

See Mayr et al., 1968: 359; Schodde and Mason, 1999: 763–764; Dickinson, 2003: 733; and Payne, 2010: 357–358.</p> <p> LECTOTYPE: <b>AMNH 720329</b>, adult male, collected at Alexandria (5 Alexandra), 19.02S, 136.42E (USBGN, 1957), Northern Territory, Australia, in June 1905, by Wilfred Stalker. From the Mathews Collection (no. 3495) via the Rothschild Collection.</p> <p> COMMENTS: In the original description, Mathews said only that his type was from ‘‘ Northern Territory (Alexandra)’’ and gave the range as ‘‘ Northern Territory.’’ The Alexandria collection was made by Stalker for William Ingram and reported on by Collingwood Ingram (1907, 1909). It was later purchased by Mathews. C. Ingram (1907: 415) recorded an adult specimen, without sex and date of collection, as <i>Stictoptera bichenovii</i> and an adult male and female (no. 54, that shared a label), collected in June 1905, as <i>Stictoptera annulosa</i>. On his label, however, Mathews had identified the female specimen collected in June 1905 as <i>S. annulosa,</i> and the unsexed, undated bird and the male collected in June 1905 as <i>M. bichenovii</i>, labeling the last as his type of <i>M. bichenovii bandi.</i> It is clear from the ranges given in his listing of the subspecies of <i>M. bichenovii</i> (Mathews, 1912a: 429) that he assigned all his Northern Territory specimens to his new subspecies <i>bandi,</i> which he regarded as intermediate between <i>M. b. annulosa</i> and <i>M. b. bichenovii</i>, and that he considered <i>M. b. annulosa</i> to be confined to ‘‘North-West Australia.’’ He had marked the Stalker label of the unsexed, undated bird (AMNH 720332) as ‘‘Type,’’ but apparently changed his mind, as AMNH 720329 bears his green type label as well as a Rothschild type label. It is this specimen that was evidently Mathews’ intended type, was so cataloged when the Rothschild Collection came to AMNH, and has since then been considered the type without question. I hereby designate AMNH 720329 the lectotype of <i>Munia bichenovii bandi</i> in order to settle the issue. Paralectotypes are: Alexandria, <b>AMNH 720331</b> (Mathews no. 3494), female, June 1905; <b>AMNH 720332</b> (3503), sex?, undated, both collected by Stalker.</p> <p> AMNH 720333, collected at Glencoe, Northern Territory, by Knut Dahl in January 1895 was not cataloged by Mathews (no. 11046) until 8 February 1912, after the 31 January 1912 publication date of <i>bandi</i> and is not considered a paratype.</p>Published as part of <i>LeCroy, Mary, 2013, Type Specimens Of Birds In The American Museum Of Natural History Part 11.

W[hitlock]. From the Mathews Collection (no. 2989) via the Rothschild Collection.</p> <p> COMMENTS: Mathews cited his catalog number of the holotype in the original description, giving the range of the form as ‘‘North-West Australia.’’ In addition to Whitlock’s original label and Mathews and Rothschild type labels, the holotype bears a ‘‘Figured’’ label, indicating that it was illustrated in Mathews (1924: pl. 512, upper fig. (identified as <i>M. laetior</i>), opp. p. 256, text p. 263), where it is confirmed as the type of <i>M. gularis coongani.</i> The following AMNH specimens are paratypes of <i>coongani</i>: Coongan River, <b>AMNH 691548</b> (Mathews no. 2988), <b>691550</b> (2990), <b>691551</b> (2991); Derby, <b>AMNH 691553– 691555</b> (8874–8876); Point Torment, <b>AMNH 691564</b> (8621); Mungi Rockhole, <b>AMNH 691565</b> (9239), <b>691566</b> (9236), <b>691567</b> (9240); Manguel (<i>5</i> Marngle, as on label) Creek, <b>AMNH 691568</b> (9237), <b>691569</b> (9238); Parry Creek, <b>AMNH 691570–691573</b> (2984–2987).

Far-Infrared Spitzer Observations of Elliptical Galaxies: Evidence for Extended Diffuse Dust
No full textFar-infrared Spitzer observations of elliptical galaxies are inconsistent with simple steady state models of dust
creation in red giant stars and destruction by grain sputtering in the hot interstellar gas at T 107 K. The flux at 24 m
correlates with optical fluxes, suggesting that this relatively hot dust is largely circumstellar. But fluxes at 70 and 160 m
do not correlate with optical fluxes. Elliptical galaxies with similar LB have luminosities at 70 and 160 m (L70 and L160)
that vary over a factor of 100, implying an additional source of dust unrelated to that produced by ongoing local stellar
mass loss. Neither L70/LB nor L160/LB correlate with the stellar age or metallicity. Optical line fluxes from warm gas at
T 104 K correlate weakly with L70 and L160, suggesting that the dust may be responsible for cooling this gas. Many
normal elliptical galaxies have emission at 70 m that is extended to 5Y10 kpc. Extended far-infrared emission with
sputtering lifetimes of 108 yr is difficult to maintain by mergers with gas-rich galaxies. Instead, we propose that this
cold dust is buoyantly transported from reservoirs of dust in the galactic cores, which are supplied by mass loss from
stars in the core. Intermittent energy outbursts from AGNs can drive the buoyant outflow
