Coptorhina; clypeus quadri-dentate, eyes showing on the upper side 

 through a narrow longitudinal slit ; suture of genae indistinct ; 

 prothorax simple, convex ; elytra convex, striate, strongly sinuate 

 above the prosternal epimera ; pygidium triangular, not vertical ; 

 metasternum very broad between the coxae, and separated from the 

 mesosternum by a straight transverse line ; legs as in Coptorhina, 

 but the anterior tibiae are only tri-dentate outwardly, and not serrate. 

 The generic distinction between Delopletirus and Coptorhina is very 

 small, and is mostly based on the shape of the clypeus ; the last 

 joint of the maxillary palpi is more fusiform, and the shape of the 

 last joint of the labial palpi differs a little. 



Delopleubus pullus, Bohem., 

 Insect. Caffr., ii., p. 210. 



Black, shining ; head covered with deep, round, small punctures 

 very closely set, genae sub-triangular, but with the anterior angle in a 

 line with the clypeus, the latter oblique, dentate at a short distance 

 from the apex which is incised and has on each side of the incision 

 a sharp tooth slightly reflexed, a little longer than the lateral one, 

 and set close to it ; the suture of the genae is nearly obliterated, and 

 ;fchere is no trace of transverse carina or raised line on the vertex ; 

 prothorax simple, not ampliate laterally, deeply sinuate laterally 

 behind, convex, and covered with closely set, deep punctures which 

 ;are not, however, quite so close in the supra-basal part which has a 

 short, median, longitudinal impressed line, as on the sides ; elytra 

 convex, more shining than the prothorax, very narrowly striate, 

 striae moderately deep and slightly punctate, intervals plane, im- 

 punctate ; pygidium directed forward, closely punctulate, and having 

 a faintly raised, median longitudina.1 line ; median part of meta- 

 sternum smooth, impunctate, and without median line or impression, 

 sides deeply and closely pitted ; apical spur of anterior tibiae straight, 

 bifid at tip. 



Length 5^-6^ mm. ; width 3^-4 mm.

" This genus comes next to Chceridittm, and differs from it, among 

 other characters, by having eight striae to the elytra, and by the 

 position of the apical spur of the anterior tibiae. Body oblong,
