distinct impression, the surface is covered with punctures similar to those 
of the head, and equally closely set ; scutellum pubescent ; elytra glab- 
rous except for a few setulose hairs on the sides of the shoulders, and a 
fringe of setae along the outer margin, very finely aciculate but not coria- 
ceous, and without any visible traces of dorsal costules ; under side and 
legs closely aciculate punctate ; anterior tarsi long ; spurs of hind tibiae 
both very short, but sharp. 
Length 8-9 mm.; width 3^ mm.

Mentum long, somewhat narrow, ligula very deeply incised in the 
centre, almost bi-lobate on that account, labial palpi short, the palpigers 
very long ; maxillae not very robust, inner lobe narrow, upper dilated, 
hairy ; maxillary palps of moderate length, the last joint very little longer 
than broad, occasionally fused with the penultimate, sub-truncate at tip ; 
mandibles robust, strongly falciform, the right one sinuate inwardly, 
and sharp ; labrum transverse, short, epistome reaching beyond the inser- 
tion of the antennae ; head deflexed, sub-vertical, broadening on the 
vertex, neck somewhat long, eyes large, not very broad, but long ; 
antennae with the first joint knobby, the second small or very small, the 
third as long as the two preceding ones taken together, in the <^ , the 
following joints are nearly equal in length to the third, not compressed 
but not cylindrical ; in the $ they are distinctly shorter, and only half 
the length of the third ; prothorax transverse, sub-quadrate, depressed ; 
scutellum very broad, and very long, rounded at apex ; elytra considerably 
broader at the base than the prothorax with the shoulders rounded, very 
deeply sinuate outwardly at about one-third of the length, the inner part 
strongly divaricating at or near the scutellary region and strongly 
attenuated thence to the apex, leaving the greatest part of the abdominal 
segments covered by the wings only ; metasternum strongly developed ; 
legs somewhat short, the hind femora more robust than the others, outer 
spurs of the posterior tibiae thick, dilated at tip, more so in the ? than in 
the S 1 scooped inwardly and either sub-truncate or acuminate outwardly 
at apex, claws broadly divaricating, upper part pectinate, lower filiform. 
This genus is easily distinguished from its congeners by the broadly 
divaricating elytra, which are gradually attenuated in the inner part from 
near the scutellary region down to the apex. 
Two species, very distinct from each other, are recorded from the South 
African area.
