174 Mr. G. C. Champion on the 



from Angola, varying in size and colour, and including 

 various males, are referred to the incompletely described 

 M. apicalis, Harold, which is said to differ from M. rufi- 

 ventris, Boh., in the colour of the abdomen, the last-named 

 having the ventral segments wholly red in $ and infuscate 

 at the base in $ . The present insect is broader and more 

 convex than Boheman's species, the type of which was from 

 Limpopo ; the head is narrower in front and snbrostrate ; 

 the prothorax is strongly convex (or even subgibbose) on 

 the disc and more finely sculptured, and has the margins 

 obsoletely erenulate ; the elytral interspaces are alutaceous, 

 transversely plicate (much as in M. nigripes, Harold), and 

 finely punctured ; and the tibiae are closely fusco-setose. 

 In one of the two females from the Stanley Falls the abdo- 

 men is wholly infuscate. The Kisantu specimen is labelled 

 M. apicalisj Harold, presumably named by Pic. 



18. Melyris denticulata, sp. n. 



$ . Elongate, rather convex; the head and prothorax black, 

 opaque, the elytra and under surface shining, nigro-violaccous, 

 the antennal joints 1-4, and the coxae, femora, and tibiae, 

 clear rufo-testaceous, the tarsi and the rest of the antennae 

 black ; fusco- pubescent, the femora and tibiae with yellowish 

 hairs, the apex of the abdomen fringed with long blackish 

 haiis ; the head and prothorax densely, minutely puuctulate 

 and reticulate. Head rather small, somewhat elongated 

 basally, not produced in front ; antenme short, joints 5-10 

 somewhat loosely articulated, broadly, acutely triangular. 

 Prothorax convex, a little broader than long, arcuately 

 narrowing from near the base, feebly canaliculate, the lateral 

 carina slightly sinuate, the hind angles obtuse, the margins 

 finely denticulate. Elytra long, much broader than the 

 prothorax, widened posteriorly, rounded at the apex; feebly 

 tricostate, the broad interspaces with about five rows of 

 rather fine punctures, the inferior apical margin erenulate. 

 Ventral segment 5 excavate down the middle anteriorly. 

 Tarsal claws sharply toothed beyond the middle. 

 Length 7\, breadth 3 mm.

One specimen received by the Museum in 1876 with 

 various examples of the insect here provisionally identified 

 as M. apicalis, Harold, from which it is readily distinguished 

 by the much narrower, black, opaque prothorax, with the 

 lateral margins denticulate ; the feebly tricostate elytra, with
