Ovate, covered with a greyish-white squamosity (to the naked 

 eye having a glaucous tint), and with a few minute black setae 

 above ; superciliary ridges raised, front with two lesser oblique 

 ridges bounding the base of the rostrum, this of moderate length, 

 marked with four foveas in front, the base with an oval tubercle ; 

 prothorax cylindrical, rather longer than broad, anteriorly with 

 three large concavities, posteriorly two lines, each of four seti- 

 gerous tubercles, having a short groove between them ; elytra 

 shortly ovate, each with three rows of tubercles, the inner row of 

 one tubercle only posteriorly and three on the declivity, the second 

 row with four, including one at the declivity and two at the apex, 

 the outer or lateral row with five, at the base two raised lines, rest 

 of the elytra obsoletely punctured except the line near the suture, 

 at the commencement of the declivity a black curved transverse 

 line ; body beneath and legs with a dense squamosity ; tarsi 

 dilated. 



The broad tarsi — an exception to the characters of 

 the genus — and the disk of the elytra non-tuhercnlate, 

 with the well-defined black apical line, will at once 

 distinguish this pretty little species.

Oblong, the elytra especially covered with minute silvery grey 

 scales, those on the head and prothorax more decidedly grey ; head 

 convex in front, a curved shallow depression marking it off from 

 the rostrum, this stoutish, entire, and indistinctly pitted ; pro- 

 thorax nearly parallel at the sides, irregularly pitted, the three 

 largest pits anteriorly, the middle one forming part of a longi- 

 tudinal groove ; elytra much broader than the prothorax, but not 

 at the base, each with a row of four or five small tubercles at the 

 side of the disc and another row of large tubercles on the inflexed 

 side, between these a brown stripe varying in certain lights, 

 posteriorly near the suture two small tubercles, the declivity also 

 with tubercles, the largest near the angle, a large oblong dark 

 brown patch, composed of erect hairs, but not extending to the
