Body clothed with a very short flavescent pubescence ; head, prothorax, 
elytra from the base to two-thirds of the length yellow, the remainder of 
the latter black ; under side except the two apical abdominal segments 
which are yellow, palps and legs black ; all antennal joints, the labrum 
and mandibles fuscous black ; head deeply punctate, especially in the 
frontal part, the punctures not set very close and leaving in the centre 
of the forehead a narrow longitudinal smooth space ; prothorax strongly 
attenuate in the anterior part for about one-third of the length, slightly 
yet distinctly sinuate thence towards the base which is broader than the 
median part, covered with moderately shallow punctures separated by an 
interval nearly equal to their own diameter, narrowly impressed longi- 
tudinally in the centre, and transversely along the carinate base; scutellum 
closely punctate ; elytra impressed laterally at the base above the shoulder, 
straight, not distinctly sinuate laterally, not much convex, and covered 
with somewhat deep punctures separated by a very narrow interval ; the 
suture is slightly raised and there are on each side two slightly raised 
lines which disappear in the posterior part ; under side and legs very 
closely aciculate punctate, and more densely pubescent than on the 
upper side. 
Length 20J- mm. ; width 5 mm. 
Hab. I am not sure that this insect is a native of South Africa. It 
was given to me long ago, and I did not record the locality at the time, 
perhaps because it was not indicated.

Deutsch. Entom. Zeitsch., xxiii., 1879, p. 402. 
Mentum longer than broad, sub-ovoid laterally, the ligular part is 
completely fused with the mentum, very strongly attenuate, parallel, 
nearly half the length of the mentum proper, slightly emarginate at 
apex and translucid ; the labial palps are set close together on the outer 
face and separated by a narrow, sub-carinate process bearing two stiff 
setulose bristles, outer face of the mentum deeply pitted, slightly impressed 
in the centre ; labial palps of normal length, the joints nearly equal in 
length, sub-cylindrical, ultimate one truncate ; maxillae very long and 
slender, inner lobe with the suture almost obliterated and weakly 
pubescent, upper lobe sub-cylindrical, lined inwardly and at the top 
with a very long pubescence ; maxillary palps very long, sub-compressed, 
ultimate one truncate at tip ; head greatly elongated and narrow, as long
