uneven. Z/yéra convex, elongate-oval, a third wider than prothorax, nearly two 
thirds longer than wide, shoulders rather square, no sinuation behind; striae 
fairly deep and very clean cut, impunctate, shallower at sides and behind, but 
I and 2 are deep to apex, 8 deep throughout, scutellary striole obsolete; 
intervals a little convex, 1 somewhat raised and narrower towards apex, 3 with 
a pore behind middle and another before apex, surface a little uneven. No 
appreciable microsculpture. Underside impunctate; tarsal joint 5 glabrous 
beneath. 
A little smaller than average examples of 7: pallipes Germain, the eyes 
flatter, the prothorax wider, its sides straight behind, its base punctate, the 
elytra much more deeply striate and without microsculpture.

somewhat dilated, clypeal suture fine, with a 
small pore or impression at each end, re- 
presenting the frontal foveae, front and vertex 
with a few vague rugae, labrum and clypeus 
both slightly emarginate, eyes small and rather 
flat, antennae barely reaching base of pro- 
thorax, ligula bisetose, truncate at apex, the 
paraglossae narrow, membranous, separated 
from the ligula on each side by an evident 
notch, curving inwards and extending rather 
beyond it, tooth of mentum bifid, a pair of 
setiferous pores just below it, the epilobes

quadrate, rather more than a half wider than

wider than apex, both slightly and widely emarginate, front angles rather 
sharply rounded, sides bisetose, with a very narrow border, gently rounded

widest a little before middle, basal border entire, sides gently rounded up to 
a fifth from base, where a further widening and flattening takes place, a deep

the extremities, which are separately rounded, forming a declivous apical lobe;
