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



temporal foveolae, which are, however, small and very imperfectly 

 developed and not at all marginate from below. Eyes rather promi- 

 nent, oval, slightly higher than long, not higher than subocular 

 distance. Cheeks more or less rugulose, with the oblique sulcus 

 moderately deep. Pronotum rather compressed laterally, slightly 

 narrowed anteriorly, more or less rugose ; prozona convex ; meta- 

 zona, which is subequal to the prozona in length, flat ; median keel 

 feeble, sometimes scarcely perceptible; transverse sulci deep, 

 practically straight; lateral keels indicated only by an interrupted 

 row of feeble tubercles and carinulae, not reachmg the hind margin ; 

 lateral lobes higher than long, with the lower margin straight in the 

 hind half, rotundato-angulate, but not prominent, in the middle, 

 and ascending in the fore half; fore angle very obtuse, rounded; 

 hind angle a little more than 90°, rounded; hind angle of the disc 

 about 90°, scarcely rounded. Prosternal tubercle not at all or but 

 slightly longer than broad, more or less distinctly compressed in 

 transverse direction, obtusely triangular, or with the apex strongly 

 rounded, not truncate. Mesosternal interspace in the male subequal 

 to, or slightly more narrow than, one of the lobes; in the female 

 transverse, distinctly broader than one of the lobes. Elytra with 

 the fore margin strongly prominent in the basal half, distinctly 

 narrowed apically, with a rather sparse reticulation. Hind femora 

 of the male strongly incrassate, with lower margin of the externo- 

 median area distinctly inwardly bent; the lower outer sulcus 

 feebly impressed and sometimes even slightly convex ; lower carina 

 from the base (where it is low and in some species even almost 

 obliterate) up to the middle straight, strongly convex just beyond 

 the middle, and again straight near the apex ; the broadest part of 

 the lower outer sulcus just beyond the middle; lower inner sulcus 

 dilated, almost flat, or even slightly convex. Hind femora of the 

 female less incrassate than those of the male; the lower carina of 

 the externomedian area straight ; lower outer sulcus less dilated, 

 its broadest part beyond the middle; lower inner sulcus feebly 

 dilated, scarcely concave. Hind tibiae of the male distinctly, or 

 even strongly incurved ; of the female practically or quite straight. 

 (^. Two last abdominal segments widened and incrassate; the 

 hind one with a deep rotundate emargination, mth the hind margin 

 strongly chitinised, depressed. Supra-anal plate transverse; hind 

 angles straight, or nearly so, not rovmded; hind margin truncate, 

 with a triangular lobe and small emarginations at the base of the 

 latter ; median keel feeble, sulcate throughout and bifurcate basally ; 

 a transverse row of four chitinous tubercles in the middle, and one 

 tubercle at the base of the median sulcus. Cerci hook-shaped, 

 vertical, with the apical (ascending) part longer than the basal one,
