very finely and sparingly in one example before me) punctulate, 
and that the front tibise are only gently curved. 
Resembles H. opacula, Bates, in many respects, but the men turn 
seems to be quite different, the prothorax more strongly transverse, 
the elytra very differently sculptured (in opacula they are “faintly 
striate” with their punctures “irregular, frequently two or three 
run together”), &c., &c. 
The elevated apex of the prosternal process (appearing as though 
it bore a shining tubercle) is a notable character, as also the 
comparative feebleness of the thickened basal margin of the 
elytra, and the evident (though slight) iridescence of the head and 
prothorax.

L, SIMPLEX, Westw. 
An example recently taken near Adelaide by Mr. Rothe agrees 
quite satisfactorily with the description of this insect, and also 
with that of L. funerea, Pasc., which, I should say, is almost cer- 
tainly a synonym of the same species. 
Amarygmus. 
M. Blessig (Hor. Soc. Ent. Ross. 1861) in founding the genus 
Chalcopterus for certain species that had previously been 
attributed to Amarygmus, together with some previously un. 
described insects, expresses a doubt whether any true Amarygmus 
is to be found in Australia, stating, however, that the number of 
species he had been able to examine was very small. He states 
that in true Amarygmus the apex of the mandibles is bifid, and 
that in all the Australian species he had seen, the mandibles are 
truncate at the apex. The observation is undoubtedly a valuable 
one, whether Chalcopterus be regarded as a genus or merely a sub- 
genus ; but the conjecture of the non-occurrence in Australia of 
true Amarygmus is a mistaken one, as there are many species 
with the mandibles formed as he asserts them to be in that genus.
