This species is evidently allied to L. ferrugineus, Blanch., 
from which it is easily distinguishable by, inter alia, the much 
closer and stronger punctnration of its elytra, and the very 
•evidently greater length of the basal joint of its hind tarsi.

This species may be described as superficially a close ally 
of L. p/ioe7iicopferifs, Germ., having antennae consisting of 
only seven joints. No other known to me of the species with 
similar antennre (seven-jointed) bears the least resemblance 
to it.

MiCROTHOPUS. 
I diagnosed the genus J/ftrleai/la in Tr.R.S.S.A., 1887, 
and in the same volume added a note as to the possibility of 
its identity with Burmeister's genus Mirrofhopus. Since that 
time I have had the opportunity of examining large numbers 
of Liparetroid Coleoptera, from Western Australia, and as T
