Type, //. spinicoriiis, Ne\vt)i. 



Haiuje. Northern India to New Guinea. 



Head strongly exserted; vertex marked with a deep median 

 groove extending between the eyes and continued as a shallower 

 groove between the antennal supports; the latter depressed; 

 front oblique, marked with a fovea on each side; mandibles rather 

 long in the J , straight at base, sharply turned in at apex ; eyes 

 deeply emarginate, not extending past the antennal supports in 

 front, the genae in consequence rather long. Antennte from one- 

 fitth to one-third longer than the body in the male, and a little 

 shorter than the body in the female, the joints from the third 

 to the tenth spined posteriorly at the apex and the fifth to 

 tenth acutely angulate or subdentate in front, especially in the 

 female ; fourth joint much shorter than the third or fifth, 'eleventh 

 joint much longer than the tenth in the male, a little longer 

 than the tenth in the female. Prothorax somewhat longer than 

 broad, constricted in front, rounded at the sides between the 

 anterior constriction and the base ; transversely wrinkled above, 

 but with a smooth space on the middle of the disc. Elytra convex, 

 narrowed posteriorly, truncate at the apex. Leijs moderately long ; 

 femora slightly compressed, the hind pair scarcely reaching to the 

 apex of the elytra in the J ; first joint of hind tarsus nearly as 

 long as the next two united. Acetabula of front coxaj closed on 

 the outer side as well as posteriorly ; intercoxal process truncate 

 posteriorly.

Brownish black, the elytra varying in colour from piceous 

 to reddish brown; a fine grey pubescence covers the head, pro- 

 thorax, antennae, legs, and underside; the elytra more densely 

 covered with a silky pubescence of a fulvous grey tint and some- 

 what banded in lighter and darker sbades uhicii alter with the 

 incidence of the light. Head with the eyes well separated above 

 and the space between marked with a deep median groove ; a 

 shallower groove, bounded on each side by a slight carina, extends 

 thence between the antennal tubers ; gular area with three 

 strong transverse ridges. Antennae of the male longer than the 

 body by fnmi one-fifth to one- third of their length accordino- to 

 the size of the individual ; faintly pubescent ; first joint sparsely 

 and strongly punctured, third to sixth or seventh more or less 

 asperate at the edges, flattened or slightly canaliculate above •
