There seems to be reason Per) reparei all the Australian in- 
sects that have been agg s is genus as incorrectly placed 
there. 7. posing’ it New Ta bei been made the typical 
species of a new genus (Metabasis, Gorh.), and Mr. Gorham has 
already ref ie I have no doubt) 7. sculptus, Macl., 
and his own 7. rufimanus to the genus Aulicus. Necrobia eximia, 
White (which has been attributed to Thanasimus by some 
authors,—e.g., Gorham) is certainly not a TAanesimus in my 
present discuss its position more particularly. I know of only 
three other Australian species that have been placed in 
Thanasimus M ., acerbus, Newm., confusus Newm., and 
cursorius, Westw.), and they pese tedly belong to the genus 
Stigmatium. "They are all described insufficiently for confident 
identification among pleat so numerous and superficially 
so closely resembling each other as are the species of Stigmatium 
but it seems to me probable that acerbus and cursorius are 
founded on the same insect and that it is also the same which M. 
Kuwert has since descri as S. dispar. I think I know 
S. confusus, Newm., as a species that I have met with in Vic- 
toria (Newman’s locality) not rarely, and it is probably identical 
with one or more of the species that have since been descri 
Stigmatia by other authors, but without examination of types it 
is difficult to arrive at a confident opinion. 
I regard it as extremely dotadi whether any true Clerus 
occurs in Australia. Eight Australian species are ascribed to the 
genus in Masters’ Catalogue, one of which (crassus, Newm.) dis- 
appears in Lohde's Cat., having been reported (Tr. R. Soc., S.A.,
