sutural stria and the first pair of rows of punctures, and between 
the first and second pairs of rows of punctures (are not con- 
fusedly and rather closely punctulate but) bear only a few punc- 
tures and they placed interruptedly in a longitudinal direction. 
Its pygidium is somewhat irregularly studded with rather large 
isolated punctures with which fine punctures are not intermingled 
except in the antero-external corners (and there not very closely). 
In other respects the description of C. bifossus applies to the 
present species.

This species has a single large excavation and horn-like tubercle 
on its prothorax, with close comparatively coarse puncturation 
resembling that of C. accedens. Its elytra have their first inter- 
stice (between the subsutural stria and the first pair of rows of 
punctures) confusedly and strongly but not closely punctured, 
while the interstice between the first and second pairs of rows of 
punctures bears a single row of strong punctures. The pygidium 
of the male type has fine puncturation mixed with the coarser 
punctures but less closely than in C. bifossus; that of the 
females before me has very little fine puncturation. Compared 
with C. latipes (female) the female of this species is much less 
narrow and cylindric, with the prothorax evidently less closely 
punctulate, the first elytral interstice much more punctulate. 
The space in front of the furrow on the last ventral segment is 
closely rugulosely and somewhat finely punctulate.

C. juvencus, Burm. The insect which J take to be this species 
is, I should judge, not uncommon in the neighborhood of Sydney ; 
for though I have never taken it myself in my occasional collect- 
ing there I have not infrequently received it from Sydney corre- 
spondents. Comparing it with the description of C. bifossus 
(above) I find the following distinctions: the clypeus is very 
little elevated along its front margin and not more so in its
