 a broad mesopleural sti'eak, two discal niesonotal vittte and apex 

 of metathorax on either side, white; notauli short and deeply 

 impressed ; areola cordiform, subglabrous, a little longer than 

 broad, not extending to base, and emitting strong costulas ; 

 sph-acles linear, apophyses wanting. Scutellum convex, margined

 Length, 11 mm. c? only. — At once known by the definite 

 thoi'acic white markings and by the clypeal fossa. — A couple of 

 males fi'om Uganda : one at Chagwe in the Mabii-a Forest at 

 some 3500 feet in the middle of July 1911 ; and the other

 towards the end of the following month. 



G. MUNDATUS Tosq. 



This is probably not an uncommon species in Central East 

 Africa, since I have seen several males, but nothing that I can 

 assign as its female. The peculiarly elongate form and dull red 

 coloration are distinctive ; and the punctate postpetiole assigns 

 it to the present genus, though Tosquinet (Mem. Soc. Entom. 

 Belg. V. 1896, p. 31) described the male under Ichneumon, in its 

 Wesmaelian sense. The extent of black markings is variable : 

 the thorax is usually black with a tiavous pronotal callosity, and 

 the mesonotum, excepting a discal vitta, red ; sometimes the 

 iiavous is become red ; at others the black central mesonotal line 

 is lacking, or the spiracular and dentiparal areas aj'e also red, 

 with or without the propleurag. Also all the coxfe and trochanters, 

 or as in the type only the anterior coxfe above, are black. — The 

 specimens from which these details are drawn come frora Higo 

 Samula in Abyssinia on 30th October, 1911 {li. J. Stordy); 

 Abyssinia, probably about Harrar, in 1910 (Collector ignot.) ; 

 and one, which considerablj' extends its known range, from the 

 valley of the Rukuru River between 20tli and 27th June, 1910, 

 at 3000 feet, in Nyasahind. Another male, difiering solely in its 

 black legs with only the anterior tarsi red and inner side of front 

 tibise flavous, was found on the west slopes of Mount Kenya, on
