Klug's Beleopterus signatus, besides my species which follow 

 (N. Championi and N. intermedia). 



Subgenus 2. Belonognatha. 



Elytra polished and shining, without aciculation ; body con- 

 vex, and mandibles usually prominent and acute. 



This subgenus contains the species which are described below 

 (B. rugiceps, obesa, and quadrinotata) ; besides, doubtless, Chau- 

 doir's species, B. pustulata, and, possibly, Klug's Beleopterus 

 cyanipennis. 



The species received from Old Calabar are as follows, viz. : — 



1st Subgenus. (Nycteis proper.) 

 1. N. Championi, mihi. 



Parum depressa, nitida, fusca vel picea; ore, antennis, tho- 

 racis lateribus, elytrorum marginibus, macula basali et fascia 

 irregulari apicali atque pedibus, testaceis ; capite fere lsevi, 

 mandibulis non valde prominentibus ; thorace late marginato; 

 elytris striato-punctatis, interstitiis convexis et impunctatis, 

 apice oblique truncato et exciso, angulo exteriore apicali acuto; 

 unguiculis pectinatis. 



Long. 4 lin., lat. 1 j lin. 



Slightly depressed, shining, brown, with the mouth and an- 

 tennae, the margins of the thorax and elytra, a patch towards the 

 base and a jagged irregular band towards the apex of the latter, 

 and also the legs, testaceous. Head as broad in front as behind, 

 nearly smooth, with some faint wrinkles upon it, and two con- 

 siderable depressions on each side, the smallest one on the inside 

 of the eye, and the other larger before it ; clypeus transverse, de- 

 pressed in front ; labrum rather broad, and not tapering, rounded 

 at the anterior angles, slightly emarginate and with a shallow 

 longitudinal groove in the middle in front ; mandibles slightly 

 rounded exteriorly, not much projecting; antennae darker to- 

 wards the apex, slightly flattened and thickened from the end of 

 the fourth joint to the apex; eyes large and prominent. Thorax 

 broad, short, transverse, and somewhat cordiform, with very 

 broad, shallow, semitransparent, reflexed margins, marked in 

 the bottom with faint transverse depressions or fovese; disk 

 slightly convex, with a longitudinal dorsal line reaching from 

 the front to the base, and a semicircular impression in front ; 

 faintly marked with transverse wrinkles ; posterior angles some- 

 what obtuse. Scutellum impunctate. Elytra broader than thorax, 

 slightly expanded posteriorly, punctate- striate, interstices convex 

 and impunctate; a fovea on the second stria near the apex,
