margin is sti’ongly emarginate, the base strongly bisinuate. Com- 
pared with the common 31. sordiclus, Boisd., the puncturation of 
the head is closer and not so strong, and that of the prothoras 
much better defined and running in transverse or oblique series so 
that the intervals appear as a system of transverse and oblique 
wrinkles. The sculpture of the elytra bears much resemblance to 
the same in 31. sordidus. The setse over the whole surface (at all 
events in the specimen before me) are not at all conspicuous. The 
anterior tibiae bear three rather large very blunt external teeth. 
The underside is shining and coarsely and deeply punctured.

An extremely distinct species not falling very naturally into 
any of Mr. Macleay’s sections of the genus. Its clypeus beais 
much resemblance to that of L. basalis and its allies, but it has 9- 
jointed antennse. The elytra are short scarcely reaching half-way 
from the base of the prothorax to the apex of the pygidium ; they 
have no trace of geminate striae and their sculpture consists of 
nearly regular rows of punctures; the te.staceous colour occupies 
the whole surface except the base suture and lateral margins. The 
propygidium (in one se.x at any rate) is enormous. The head, pro- 
thorax (except on the lateral m.argins) and elytra are glal)rous, the 
propygidium, pygidium and underside sparingly furnished with 
rather short hairs. The two external teeth on the anterior tibim 
are small (the upper smallest) and sharp, the ajiical [»art of the
