臺灣產福姬蜂亞科之分類（膜翅目：姬蜂科）
No full textThe subfamily Phrudinae of Ichneumonidae has not been recorded from Taiwan. This paper presents 5 genera and 11 species from this island. Two known species, Phrudus monilicornis Bridgman and Earobia paradoxus Perkins are new to Taiwan, and 9 species namely Brachyscieroma townesi Chiu, B. umbilici Chiu, Lygurus marjoriae Chiu, Phrudus longius Chiu, P. montanus Chiu, P. angustus Chiu, P. linorum Chiu, Astrenis granum Chiu, and A. densa Chiu are new to science.
福姬蜂亞科(Subfamily Phrudinae)乃姬蜂科中之一小科。體型甚小，僅知其係甲蟲類民蟲之內寄生(internal parasitoid)。該亞科妒蜂全球記載10屬(genus)，零星分布於舊北區（Palearctic Region )，新北區(Nearctic Region)，新熱帶區(Ethiopian Region)，及東洋區(Oriental Region)。本省尚無記錄。
本文記載本省產之福姬蜂亞科5囑、11種內合2新記錄種(new record), Phrodus monilicornis Bridgman 與Earobia paradoxus Perkins，及9新種(new species)，分別為Brachysleroma townesi Chiu, B. umbilici Chiu; Lygurus marjoriae Chiu; Phrudos longius Chiu, P . montanus Chiu, P. angustos Chiu, P. linorum Chiu; Astrenis granum Chiu 及A. densa Chiu.全部標本均從本省高山森林用掃網採得，而L. marjoriae Chiu 與E. paradoxus Perkins 係借自美國昆蟲學研究所，其餘標本均保存於臺灣省農業試驗所昆蟲標本館
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

Xanthopimpla calva Townes & Chiu 1970
No full textXanthopimpla calva Townes & Chiu, 1970 Xanthopimpla calva Townes & Chiu, 1970. Mem. Amer. Ent. Inst., 14: 240. Holotype: ♀, the Philippines: Gapan, Nueva Ecija (AEIC). Xanthopimpla calva sexcincta Townes & Chiu, 1970. Mem. Amer. Ent. Inst., 14: 241. Holotype: ♂, Malaysia: North Borneo (BPBM). Diagnosis. Propodeum without carinae, except apical part of lateral longitudinal carina present; first tergite broad, shorter than apical width; metasomal tergites 1, 3, 4, 5, and 7 each with two black spots; ovipositor sheath 0.35x hind tibia. Distribution. Pham & Le (2007) have recently recorded X. calva from Nghe An Province, Central Vietnam. Outside Vietnam, this species has been recorded from India, Myanmar, Malaysia and the Philippines (Yu et al. 2005). Remarks. Four subspecies are currently recognised: X. calva calva, X. calva calcis Townes & Chiu, X. calva periscelis Townes & Chiu from the Philippines, and X. calva sexcincta Townes & Chiu from India, Myanmar and Malaysia. The specimens recorded from Vietnam belong to X. calva sexcincta, which differs from the nominate subspecies and from X. calva periscelis by the presence of black marks on the first tergite, and can be distinguished from X. calva calcis by the apically black mid and hind tibiae.
