200 Descriptions of new Ceylon Coleoj^tera. [no. 2, new series, 
antennal club is composed of 4 joints, the 3 first of which are 
strongly compressed, the 4th being plump and of the shape of an 
acorn with its cup, all are strongly ciliated. The thorax is conic, 
firmly applied to the base of the elytra as in the preceding species, 
depressed and with 2 pits at the base, posterior margin with 2 si- 
nuosities. The shoulder-ridges of the elytra are short but rather 
strongly marked. The tibiae are narrowed, subcylindric and hairy 
at the apex. Joints 2-3 of the tarsi are subequal, the anterior pair 
more, the intermediate less coiitracted.

Of the usual brown color, legs and antennae lighter, tarsi and 
palpi quite so, femora nigrescent at the apex, hairs of occiput and 
thorax rather long. The former slightly narrowed behind, the head 
thus of a somewhat rhomboid form. Antennal club composed of 3 
joints, the 2 first of which are strongly globose, the last being 
acuminated and slightly cut away on one side at the apex. The 
mandibles are furnished with an acuminated tooth at the mid- 
dle, bent at the apex and, what is rather uncommon in this gr, 
gradually enlarged towards the base. The thorax is obconic, 
rather longer than broad. The elytra are somewhat more stretch- 
ed than usual in this group, the rudimentary humeral costa are 
rather prominent and they are separately rounded off at the apex. 
Tibiae more or less elongated, slightly bent at the base and apex, 
at the latter place subcylindric and hairy. Tarsi with joints 2-3 
subequal, first pair slightly contracted. A sexual distinction ap- 
pears to be expressed in the length of the tibiae which are less 
elongated in certain individuals which are at the same time less
