glabrous in E. verecinida, stoutly trans-striate throughout, tlie 

 rugose scutellum but simply convex, the metanotal areola half as 

 long again as broad, rectangular, flat and not shining, and the 

 second segment like the anus apically white. — Entebbe in Uganda 

 during the first half of September, 1911,

The Trogus group of Joppid genera consists of Dinotovms, 

 Catadelphits, Trogits^ and Automcdus. Dalla Torre's Catalogue of 

 1902 listed thirty-three species of the main genus, but seven 

 of these belong to Dinotomus and one {teste Yiereck, Proc. U.S. 

 Nation. Mus. xlvi. 1913, p. 369) to Aglctojojjjxo, and a ninth 

 proved to be synonymous ; but none of them have hitherto been 

 known from Africa. Automalus, with its single pala?ai'ctic and 

 single Alaskan species, is equally unknown ; but the widespread 

 Dinotomus lapidator Fab. extends to Algeria from the north. 

 Catadelphus was represented by a couple of kinds, both described 

 in 1896, but not since recorded. In 1844, Wesmael split off 

 Automalus from Trogus on account of its straight and not 

 centrally angled clypeus, and ten years later he erected Cata- 

 delphus for the reception of Ichneumon arrogator, because its 

 scutellum was simply convex and not pyramidal as in the more 

 typical species. Several of Cameron's Indian Joppides also 

 belong to the present group, but there will at present be need to 

 consider no more than one of them. 



1. gryps, sp. n. 



An extremely large and stout, blue-black species, with the 

 flagellum except apically and legs except basally, conspicuously 

 pale. Head, thorax, and apical attenuation of flagellum black, 

 with the centrally elevated face and sometimes the temples 

 badious ; clypeus apically truncate, labrum strongly exserted. 

 Mesonotum and scutellum very dull and dead black with the base 

 of the former longitudinally impressed, the latter not strongly 

 elevated and laterally carinate only to its centre ; metanotuni 

 rugose with areola triangular, costula3 strong though irregular, 

 and a basal prominence on either side. Abdomen black or blue- 

 black and smooth with basal segment dull, finely punctate, and 

 centrally bicarinate ; terebra stout and hardly exserted. Legs 

 long and stout, bright testaceous with coxte. trochanters (front 

 ones badious) and onychii alone black. Wings large and ample, 

 strongly and evenly fumate, with blue reflection ; discoidal cell 

 narrow and parallel- sided ; nervelet small ; areolet higher than 

 broad, elongate-triangular and coalescent above. Length, 26 mm. ; 

 exp. al. 48 mm. 2 oi^^y- — Larger than Catadelphus nigrocyaneus 

 with dull mesonotum, no white flagellar band, &c. ; most closely 

 allied to the Sonoran T. atroccerideus Oresson. — Gowdey found
