the eyes are much closer together on the vertex than described 

 in that species, the fourth joint o£ the hind tarsi is shorter, 

 and there are no lateral teeth on the clypeus. The sculpture, 

 however, seems to be very similar. 



Subfamily Sphecinje. 

 Sphex (Coloptera) crassifemoralis, sp. n. 



d . Nigra ; mandibulis, apice excepto, flagello articulis sex basalibus, 

 pronoto lateribus, callis humeralibus, tegulis, mesonoto utrinque 

 ante tegulas, petiolo subtus, sternitie, in medio nigro-suffusis, 

 tergito septimo, pedibusque ferrugineis ; femoribus, trochante- 

 ribus intermediis posticisque coxisque posticis, supra nigris ; 

 tibiis posticis supra nigrolineatis ; alis sordide flavo-hyalinis, 

 apice leviter infumatis, venis ferrugineis ; pronoto mesonotoque 

 fortiter transverse striatis ; scutello postscutelloque fortiter 

 longitudinaliter striatis, convexis, haud lamellato-productis ; 

 tergito septimo apice late truncato. 



Long. 22 mm. 



c?. Clypeus broadly truncate at the apex, broader than 

 long. Eyes distinctly, but not very strongly convergent 

 towards the clypeus ; posterior ocelli nearly half as far again 

 from the eyes as from each other, and twice as far from the 

 hind margin of the head as from each other. Head strongly 

 narrowed behind the eyes, the clypeus and front densely 

 clothed with pale golden pubescence. Propleursa coarsely 

 rugulose ; mesopleurse and sides of median segment irregu- 

 larly obliquely striated, coarsely punctured between the 

 si ria3 ; a broad band of pale golden pubescence on the meso- 

 pleurse behind, a patch of the same below the humeral calli, 

 and a patch on each side of the median segment at the apex. 

 Dorsal surface of the median segment coarsely obliquely 

 striate-reticulate. First joint of petiole a little shorter than 

 the hind femur and trochanter combined ; second tergite sub- 

 triangular, a little longer than its apical breadth. Hind 

 femur stout and massive as compared with the allied species; 

 pulvillus large. 



Bab. Southern slopes of Mt. Elgon, 5100 to 5800 ft. (S. A. 

 Neave), June 8-13, 1911 ; Valley of Nzoia River, N. Kavi- 

 rondo, 5100-5400 ft. {S. A. Neave), June 5-7, 1911. 



Nearly allied to S. saussurei, Buyss., and S. tuber culiscutis. 

 Turn., but is a more robust species, and differs in the simple 

 scutellum and postscutellum, which are produced in alamelli- 

 form mariner in the two species mentioned. The clypeus is 

 very different to that of tuberculiscutis <$ , also the pronotum, 

 and the petiole is shorter. 



Type in British Museum.
