A second example of this insect (in the collection of C. French, 
Esq.) is larger (long. 12 1.) and has the lateral parts of the pro- 
thorax a little less closely punctulate, but presents no other 
difference. The clypeus of this species as of the others of the 
genus known to me is somewhat narrowly produced forward in 
the middle, and the apex of the projection is rather strongly re- 
flexed. This species may be at once distinguished from all the 
others of the genus that I have seen by its almost levigate elytra 
which are marked only with a fine sutural stria two or three ob- 
solete striz (resembling faint wrinkles) and some very faintly 
impressed and distantly placed punctures.

LV. bidentatus, sp. nov. Mas. Sat brevis; minus latus; sat 
nitidus ; subtus sat dense rufo-hirsutus ; rufus ; capite cornu 
vix recurvo acuminato minus elongato armato ; clypeo antice 
fere equaliter rotundato, margine reflexo sat alte cincto ; 
prothorace quam longiori vix dimidia parte latiori, antice

The two small sharp tubercles placed one on either side of the 
middle of the front margin of the prothorax distinguish this 
species from all the others yet described of the genus.
