not sure whether it is natural and not due to discoloration 

 after death. 



The British Museum collection contains also three speci- 

 mens of a very closely related insect fsora West Africa^ 

 which differ from the Uganda ones only in the median fascia 

 of the pronotura being reduced to an elongated spot between 

 the first a,nd third sulci ; as that fascia is perfectly constant 

 in the whole Uganda series, I take this character as a sub- 

 specific one and propose the name subsp. occidentalis, nov., 

 for the West African race. The type of the latter is a male 

 from Yapi, Gold Coast {^Dr. J. J. Simpson) ; the paratypes 

 are one female from the same locality as the type and one 

 male from Lagos (Dr. H. Strachan), 



6. Stenocrohylus rhodopterus^ sp. n. 



$ . Antennae slightly flattened, reaching the hind coxae. 

 Face strongly reclinate, very coarsely punctured. Frontal 

 ridge in profile distinctly convex in its upper part, which 

 forms a scarcely perceptible rounded angle with the straight 

 lower part; its surface slightly convex above the ocellum, 

 scarcely impressed close around it, flat elsewhere, punctured 

 throughout, but more densely in the lower half ; its margins 

 parallel throughout, not at all raised, smooth, subobliterate, 

 near the clypeus. Fastigium of the vertex distinctly sloping, 

 evidently longer than broad, rotundato-truncate in front, 

 scarcely impressed, with only the lateral margins slightly 

 raised. Eyes oval, strongly prominent ; the distance between 

 the eyes distinctly narrower than the frontal ridge. Pro- 

 notum coarsely and densely punctured all over, but more so 

 on the lateral lobes; the prozona distinctly longer than the 

 metazona, feebly convex ; metazona almost flat, forming 

 distinct, though rounded angles with the lateral lobes ; 

 transverse sulci not deep ; median keel obliterated by tl>e 

 puncturation on the prozona, faintly perceptible on the 

 metazona; front margin slightly emarginate ; hind margin 

 obtusely angulate, rounded ; lateral lobes with two smooth 

 spots in the upper part of the prozona. Prosternal tubercle 

 transversely compressed, with the apex truncate. Meso- 

 sternal lobes transverse ; the interspace somewhat constricted 

 before the middle, about twice as long as its width at the 

 constriction. Metasternal interspace subequal to the dis- 

 tance between the eyes. Elytra extending somewhat beyond 

 the hind knees and reaching the apex of the abdomen. The 

 whole body and legs hairy. 



General coloration dirty olivaceous. Antennjc orpyish
