C. vividus, Blackb. I regret to find that owing to a clerical 
error the description of this species contradicts one of the 
characters assigned to it by its place in the tabulation, viz., the 
black colour of the tarsal vestiture. The vestiture is black (as 
indicated in the tabulation), although in describing the species I 
wrote (by some slip of the pen that [ cannot account for) “ tarsis 
subtus fulvo-setosis.” Of course it should have been “ tarsis 
subtus nigro-setosis.” 
OC. versicolor, Blackb. In a recent re-examination of my 
“Revision of the Australian Amarygmides” I have come to the 
conclusion that this speeies is not well placed in the tabulation. 
If the tabulation in question be referred to (P. L.S., N.S.W., 
1893, pp. 56, &c.) it will be seen that versicolor is placed among 
the species indicated under the letter ““E” (on p. 56) as having 
“the prothorax of normal form and sculpture,” but it would 
really be more at home among those indicated under EE (on p. 
61) as having the “ base of the prothorax not more than half 
again as wide as the front, front angles prominent and acute,” 
although the front angles of its prothorax are not so decidedly 
acute as in some others of that aggregate. It would then fall 
(under GG.) along with vividus, Blackb., which might be thus 
tabulated farther. 
H. Prothorax strongly transverse ; its width being 
toitslengthasl?tol  ... : ... versicolor, Blackb. 
HH. Prothorax notably less transverse.. ... vividus, Blackb. 
As there is a certain apprositatton in the form of the pro- 
thorax between some species which in my tabulation (P. LS., 
N.S.W., 1893, pp. 56, &c.) of Chalcopteri I placed in the aggre- 
gate E (on p. 56), and some which I placed in the aggregate 
EE (on p. 61); it seems desirable here to state that in those 
cases the prothorax should be looked at from the side, when it 
will be found that in the members of the aggregate EE the 
convexity of the prothorax will appear evidently less than in the 
species of the other aggregate and the lateral margins straight— 
the lateral margins in the aggregate E from a similar point 
of view appearing distinctly arched 
C. oblongus, Blackb. This is another species which in a re- 
examination of my “ Revision of the Australian Amarygmides” 
I think might have been placed more satisfactorily than I placed 
it. It is one of a very small number of species which are more 
or less intermediate between the two main groups into which I 
divided the genus Chalcopterus, having feeble (but not well 
marked) ocular sulci. JI placed it in the group having ocular 
sulci, but it would be better placed in the other group. In fact 
its ocular sulci scarcely differ from those of C. difficilis (which I 
classified among those with the ocular sulci wanting, but with
