2 posterior coxae, which, on the contrary, are more approximated than 

 in any of the species just referred to. The insect is of the light 

 brown colour of the two former, but larger and more depressed. The 

 head is strikingly large and heavy, of the width of the thorax ; 

 in its hind part, which is strongly transverse, the oval form pre* 

 vails over that of the square. Eyes small. Antennae inserted 

 under two strong protuberances rather than under a ridge ; their 

 club 4-jointed, joints 3-7 forming an inwards bent section of a 

 circle, joints 8-10 strongly compressed, obliquely truncated (sub- 

 perfoliated) 11 large, conic. The 3rd joint of the maxill. palpi is of 

 an oblongo-ovate shape, the external basal angle is prolonged into 

 a small peduncle inserted in the apex of the 2nd joint, the 4th 

 joint, about the semiglobose shape of which I am not quite satisfied, 

 appears to be obliquely inserted in the tip of the preceding. Thorax 

 oval, of a similar shape to that of the former, anterior margin slightly 

 eraarginated. Scutellum obsolete. Elytra with the traces of a 

 humeral costa, separately rounded off at the apex. Legs strong, 

 2 posterior coxae not more distant from each other than the 4 anterior 

 ones ; tibiae elongated, bent at the base and apex, at the latter place 

 slightly narrowed, subcylindric and hairy; tarsi with joints 1-4 

 subequal, in the first pair strongly contracted, joint 1 of this pair 

 produced in a spine on the inside.
