Group SCHIZOKKHINI1. 



The insects included in this group have the maxillae simple and 

 penicillate, the central part of the base of the prothorax is lobate, 

 the lobate part is rudimentary in Discopeltis, but covers the whole 

 scutellum in Amazula, Stethosdema, and Pseudoclinteria. This cha- 

 racter is also met with in Glinteroides, and to a much lesser degree 

 in Glaucocelis, but these two genera, owing to the sculpture of the 

 elytra, are included in the Sub- Tribe Leucocelites.

Muntum somewhat ampliate laterally, slightly broader at the apex 

 than at the base, deeply incised in the central part of the apex ; last 

 joint of labial palpi fusiform outwardly, somewhat acuminate ; 

 maxilla* long, the two lobes simple, the upper with a long pencil 

 of hairs, the inner densely pubescent; clypeus attenuate in front, 

 slightly sinuose laterally, deeply emarginate in the centre; eyes 

 large ; antennae normal ; prothorax diagonally ampliated laterally 

 from the apex to about the middle which is somewhat angular, 

 almost straight thence, but with a slight sinuation towards the 

 basal part the angle of which is moderately rounded, the median 

 put of the base itself being broadly triangularly produced in the 

 centre, and covering the base of the very elongated, sharply tri- 

 angular scutellum ; elytra deeply sinuate laterally, and having on 

 each side two dorsal costae obliterated or less strong in the anterior 

 pari ; the suture is plainly keeled also in the posterior part, and the 

 two intervals have two rows of elongated cicatricose punctures; 

 sternal process sub-aculeate, projecting slightly beyond the coxae, 

 grooved in the centre right to the apex, sub-truncate at apex, and 

 barely projecting beyond the coxa} ; anterior tibiae tri-dentate in 

 both sexes, the teeth remote ; intermediate tibiae sharply dentate 

 on the upper side. 



This genus has representatives on the Guinea coast and also in 

 SeiK'gambia.
