system of puncturation, the first consisting of large sparse punc- 
tures' as on head, those towards) the sides each bearing a long

tures. Elytra widely oval and convex, 10x9.5 mm., wider than 
prothorax at base, shoulders widely rounded and sub-obsolete, sides 
gradually expanding to beyond the middle, apex very blunt, its 
declivity steep ; extreme border very narrow, not seen from above,, 
without lateral gutter. Disc with four raised crenulate costse on 
each elytron, not quite extending to base, terminated at different 
points on apical declivity, the three interior costse prominent and 
nitid, their crenulation caused by rows of large punctures on each 
side, the fourth less evident and continuous, partly broken up into 
rows of tubercles ; space between eosta? slightly concave and rugose, 
irregularly covered with large punctures (larger than those on pro- 
notum), each bearing a long hair; these hairs thin and scattered 
on centre, thicker on sides, base, and apex. Abdomen densely 
minutely punctate, three basal segments with large additional punc- 
tures, bearing short seta?, prosternum finely rugose-punctate,

longitudinally as well as transversely convex form.
