compressed and more hairy in 8. pygmceus. The thorax of the lat- 

 ter is more firmly applied to the base of the elytra, the latter have 

 a fuller, more robust appearance about them, the palpi are more 

 sleuder and the tooth of the mandibles is pointed. From 8. advo- 

 i lans it would principally differ, besides in the generalities mentioned 

 above, in the shape of the thorax and in some of the points in which 

 it differs from 8. pabescens.

Of the size of 8. advolans and the plump shape and colour of 8. 

 pygmceus, the latter being rather lighter than that of 8. advolans ; 

 it has the longer hairy vesture of the former (especially on the occi- 

 put aud thorax). The occiput is slightly narrowed behind. The 

 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 sinuo- 

 sities. The shoulder-ridges of the elytra are short but rather 

 strongly marked. The tibia? are narrowed, subcylindric and hairy 

 at the apex. Joints 2-3 of the tarsi are subequal, the anterior pair 

 more, the intermediate less contracted.
