described without the kiiov^'ledge of both sexes. It is not un- 
like L. nudipennis, Germ., superficially, but is very distinct 
from that species by, hifi^r (il'ia, tlie pilosity of its elytra.

This species differs from all the others, described, of the 
same groiip, by its combination of bicolorous elytra, front 
tibiae without any trace of an external tooth above the api- 
cal projection, and hind tarsi with basal joint much longer 
than the second joint. It is rather close to />. assifniUs, 
Macl., from which (I have examined the presumable type, 
unique, in the Macleay Museum) it differs by the uniform 
whitish colour of its vestiture, (is-<iwil}s having much very 
dark brown pilosity, as well as by the much longer basal joint 
of its hind tarsi.
