156 Mr. B. P. Uvarov's Notes on 



Antennae filiform, not compressed. Face distinctly reclinate. 

 Frontal ridge in profile convex between fastigium and antennae, 

 straight in the lower part ; its margins obtuse, not raised, somewhat 

 approximated to each other near the fastigium, very feebly divergent 

 downwards, strongly divergent in the lowest part, where they are 

 almost obliterate ; surface of the ridge smooth, with a few punctures 

 in the upper part, and a feeble impression near the ocellum. Eyes 

 strongly prominent, only slightly higher than long, almost round ; 

 fore margin convex though less so than the hind margin ; subocular 

 distance subequal to their length. Fastigium of vertex strongly 

 sloping, forming an obtuse, romided angle with the frontal ridge, 

 twice as long as it is broad, somewhat widened forwards and again 

 narrowed apically; its surface impressed; margins very obtuse, 

 the apical ones even obliterate. Occiput very short, smooth. Cheeks 

 practically smooth, with the oblique fiuTow scarcely developed. 

 Pronotum compressed laterally, strongly narrowed anteriorly; 

 disc slightly convex in prozona, flat in metazona; median keel 

 very low and rather broad, with a scarcely perceptible sulcus all 

 along, in profile practically straight, feebly interrupted by the first 

 two sulci and rather deeply so by the hind sulcus, which is placed just 

 before the middle; lateral keels very obtuse, deeply cut by the 

 transverse sulci and therefore strongly sinuose, subparallel between 

 the fore margin and the first sulcus, distinctly divergent between 

 the first and third sulcus, subparallel in the metazona ; fore margm 

 of the disc practically straight; hind angle near to 90°, scarcely 

 rounded, with the sides distinctly concave ; lateral lobes slightlj'^ 

 higher than long, with the lower margin very feebly rounded and 

 in the fore third slightly ascending; fore angle obtuse, slightly 

 rounded; hind angle almost straight but more rounded; hind 

 margin straight, very oblique. Prostemal tubercle not broader 

 than long, transversely compressed, almost quadrangular, with 

 the apical angles rounded. Mesosternal interspace in the male 

 .slightly longer than broad, in the female scarcely transverse, in 

 both sexes (especially in the male) more narrow than one of the 

 lobes. Elytra much longer than the hind femora, distinctly nar- 

 rowed basally, parallel- sided in the rest, with tlie apex rounded; 

 their reticulation thick and dense. Wings coloured, with the apex 

 infumate. Hind femora rather dilated, but not incrassatc; the 

 upjier carina strongly serrulate ; the lower carina rather dilated, 

 but regularly convex. Hind tibiae a little shorter than the femora, 

 straight. 



(J. Last two tergites widened and incrassate; the anal segment 

 deeply rodundate-emarginate, with the margin depressed and 

 strongly chitinised. Supra-anal plate transverse, rotundato-trape-
