very indistinct, except towards the sides. The elytra are 

 moderately thickly punctured, with the punctures near the 

 base slightly asperate in character ; the pubescence is grey, 

 speckled with minute ashy-white spots, and each elytron has 

 an indistinct ashy-white band placed obliquely between the 

 base and middle, and on which may be seen two small 

 rounded brown spots, one towards the outer and anterior end 

 of the band, the other towards its inner extremity. The 

 mesosternum is very feebly tubercled. The antenna? of the 

 female are nearly half as long again as the body, and the 

 third joint is about half as long again as the first. 



In a small male specimen from Senegal (the Prosopocera 

 lutalenta.) Buq., of Dejean's collection) I can find no characters 

 which would lead me to believe it specifically distinct from 

 the female described above. In this male the antennal joints 

 from the third to the fifth, are somewhat thickened ; the front 

 of the head is not armed with tubercles or other processes.

In this species the prothorax is rather smaller and the 

 elytra somewhat longer than is usual in the genus Pterohphia 

 ( = Praonetha). The pubescence is of a brownish tawny 

 colour, with some small scattered spots of an ashy-white 

 colour. The front of the head, the sides of the thorax, and a 

 small elytral area around the scutellum are almost wholly 

 ashy white, while a very distinct curved band of the same 

 colour is placed a little behind the middle of the elytra. The 

 legs exhibit a number of scattered black points ; similar 

 points are to be seen along the sutural margin and on the 

 posterior part of the elytra. Each elytron, narrowly truncate 

 and feebly emarginate at the apex, has two small tufts of 

 fulvous hairs, one placed on a very small tubercle a little 

 behind the base, the other standing near the top of the poste- 

 rior slope at a little distance behind the hind margin of the 

 white band. The pubescence on the abdomen is dense and of
