ICHNEUMONIN:E IN THE BRITISH MUSEUM. 157 



in those of the metaiiotum, postpetiole, coxal scopnlee and basal 

 nervure ; tlioiigh a little stouter. Length, c? $, 11-12 mm. — 

 Of this distinct female I have seen two examples, diflering only 

 in the extent of rufescent coloration on the metanotum and 

 second segment, which were respectively captured so far apart as 

 Alaba in Abyssinia on 15th November, 1911, by R. J. Stordv, 

 and Durban in Natal during 1904, by J. P. Cregoe. 



Chasmias. 



The right of this genus to distinction from Iclmeufiion has 

 constantly been a moot point since its erection under the name 

 Chasmodes by Wesmael in 1844 {nee Cuvier, 1836) ; it was re- 

 named by Ashmead in 1900. We must, I think, look to the 

 Ethiopian fauna to supply us with a good basis of geneiic dis- 

 tinction, since less than half a dozen species have yet been 

 described altogether : one of these is from Abyssinia and was 

 discovered by Tosquinet. 



1. GLAUCOPTERUS Morl. 



This was recently brought forward (Ann. S. African Mus. xv. 

 1916, p. 365) by me from the Cape; but a second feujale, diftering 

 in nothing but its black mesonotum, anus and hind tibiae, was 

 captured in Abj'ssinia, probably about Harrar, dui-ing 1910. 



2. RUFICAUDATOE,, sp. n. 



A very strongly elongate and somewhat dull species, with the 

 head except mouth and top of face, base of antennse beneath 

 anus from a,pex of fourth segment and anterior tibije, bi'ick-red • 

 centre of Hagellum vei-y broadly but indefinitely flavous; scutellum 

 alone stramineous. Head posteiiorly as broad as the eyes, with 

 cheeks and temples buccate ; frons, the centrally elevated face 

 and the clypeus evenly and distinctly punctate, apex of the last 

 glabrous and sinuate with its centre conspicuously produced. 

 Thorax cylindrical, with superficial notauli ; metathorax closely 

 and evenly punctate with fine carinae ; areola subhexagonal, 

 apically a little constricted, extending to base and emittino- 

 costula3 from its centre ; spiracles elongate, apophyses wanting. 

 Scutellum subconvex, glabrous, with some punctures. Abdomen 

 linear, narrower than thorax and just double length of head and 

 thorax, dull and very closely punctate, with the postpetiole 

 evenly punctate on either side of its glabrous and nitidulous 

 centre; second segment fully twice as long as broad, Avith the 

 deeply impressed gastrocoeli narrower than their intervening 

 space ; fourth and fifth segments discall}^ quadrate ; valvulje red 

 and hardly exserted. Legs not long, tarsi slendei' ; front femora 

 internally and their tarsi also rufescent. Wings subhyaline, with 

 stigma black; areolet as broad as high, not laterally coalescent 

 above; nei'velet elongate but evanescent. Length, 18 mm.
