Gettysburg, Pennsylvania November 16, 1967
Dear Viv and Mac:
As usual your little note on ray birthday made me feel young and gay rather than what the calendar says.
We are looking forward to boarding the train for California on the 28th of this month as the weather has turned bitter cold here.
The General planned a surprise dinner for me inviting some local friends. We had a gay time. The party was small enough to be that way.
We are both looking forward to seeing you.
With my warm personal regard, w»#****

Assessing the impact of aerodynamic modelling on manoeuvring aircraft
No full textThis paper investigates the impact of aerodynamic models on the dynamic response of a free-flying aircraft wing. Several options for the aerodynamics are evaluated, from two-dimensional thin aerofoil aerodynamics and unsteady vortex-lattice method up to computational fluid dynamics. A nonlinear formulation of the rigid body dynamics is used in all cases. Results are generated using a numerical framework that will allow in the near future multi-disciplinary fluid/structure/flight analysis. In this paper, flexibility effects are neglected. A validation for fluid/flight models is presented. The well-established approach based on stability derivatives is also used, and is found in good agreement with solutions obtained from linear aerodynamic models. The uncertainties in predicted trajectories of the free-flying wing are, in general, large and attributed to the aerodynamics only. This suggests that a careful control law synthesis should be done to account for uncertainties from modelling technique

Antennae 15-segmented (according to the original description of S. variegatus; antennae of the examined male are broken); F1 strongly incised and expanded apically. Head in anterior view more quadrangular than in females; transfacial line 1.1 times as long as height of compound eye; malar space about 0.7 times as long as height of compound eye. Body color mainly yellow, except the ocellar area and the anteromedial part of pronotum, which are dark. Distribution. USA. Different localities from the state of California (McCracken & Egbert 1922; and in this work, see the additional material). Biology. Synergus flavens was described from specimens bred from galls of Heteroecus flavens (McCracken & Egbert, 1922) on Quercus vaccinifolia Kellog (Protobalanus section) (McCracken & Egbert 1922). Synergus flavens was also reared from galls of Trichoteras coquilletti Ashmead, 1897 on Q. chrysolepis Liebm. (Protobalanus section), according to the labels of some of the non-type specimens found in USNM (see the additional material). Synergus variegatus was bred from galls of Heteroecus pacificus (Ashmead, 1896) on Q. vaccinifolia (McCracken & Egbert 1922). Remarks. Synergus flavens was described from 4♀ (McCracken & Egbert 1922: 55) and S. variegatus, from 4♂ and 7♀ (McCracken & Egbert 1922: 52). We located and examined 3♀ of S. flavens (1♀ deposited in CAS with a ‘Type’ label and 2♀ deposited in USNM) and 2♂ and 3♀ of S. variegatus (1♂ and 1♀ with a ‘Type’ label deposited in CAS, and 1♂ and 2♀ deposited in USNM) belonging to the type series of each species. The authors comment that the ‘Type’ of these species was deposited at the Stanford Entomological Museum, later absorbed by CAS; however, in the ‘Type’ section they do not specify anything else but the type depository. As a result, and since the descriptors did not designate a holotype, a lectotype for each species has been designated and deposited in CAS. After examining the type material of S. variegatus, we noticed that its type series is composed, in fact, of two different species: while the two specimens deposited in CAS (the lectotype and a male paralectotype) are identical to S. flavens, the rest of specimens belonging to the type series that are deposited in USNM correspond to S. pomiformis (Ashmead, 1885) (see below). The original description of S. variegatus provided by McCracken & Egbert (1922) does not give us any significant morphological clues to determine which specimens of the type series truly correspond to this species. However, both S. flavens and S. variegatus were originally described from specimens obtained from galls of Heteroecus on oaks of the Protobalanus section; so, only the two specimens of S. variegatus deposited in CAS may correspond to what McCracken & Egbert described as S. variegatus. Hence, in accordance to the above mentioned, S. variegatus (in part) is proposed as a new synonym of S. flavens. Synergus pomiformis and S. flavens were described from specimens obtained from very different gall morphotypes, so it is more than probably that the specimens composing the type series of S. variegatus were obtained from a mix of galls.Published as part of Lobato-Vila, Irene, Equihua-Martínez, Armando, Estrada-Venegas, Edith G., Cibrián-Tovar, David, Barrera-Ruíz, Uriel M. & Pujade-Villar, Juli, 2020, Synergus Hartig species group (Hymenoptera: Cynipidae: Synergini) with partially smooth mesopleurae from the New World, pp. 1-38 in Zootaxa 4822 (1) on pages 16-18, DOI: 10.11646/zootaxa.4822.1.1, http://zenodo.org/record/445051
