Homotrtsis. 
H. TRisTis, Germ. 
This species (on srhicli the genus Hoinoti'ysis was founded by 
Mr. Pascoe) is extremely plentiful in South Australia. I feel no 
doubt that Allecida carhanaria, Gena., is identical with it. The 
author states that it is extremely close to tristis, but is a little 
larger, with the elytra not wider behind the middle and more 
deeply striated, and the prothorax more densely pilose. I have 
sjjecimens, some larger and some smaller than average tristis, 
which display some or all of the other distinctive characters 
mentioned, but they do not appear to be specifically distinct. 
The character's of Homotrysis, as given by Mr. Pascoe, are very 
slight; one of them (viz., that the 2nd and 3rd joints of the 
anterior tar.si are “ not longer ” than the first) is very puzzling, 
as I do not know any Allecula in which they are longer, and in 
another sentence Mr. Pascoe speaks of the exceptionally short 
basal joint of the tarsi in Homotrysis. 
H. (Allecula) fuscipennis, Blessig. 
This is stated by its author to be near li. carhonaria, Germ., 
and is probably congeneric with that species. A comparison of 
M. Blessig's description of A. fitscipennis with Mr. Pascoe’s of 
his Homotrysis microderes points strongly to the probability of 
their being identical specifically, in which case Mr. Pascoe’s 
name must fall ; both names were founded on specimens from 
Victoria. M. Blessig’s descriptions. I may remark en jjossayit, 
are models of lucidity, and his brief memoir on Australian 
Heteromera is in all respects admirable. Would that we all 
exhibited like ability and care !
