Boisd., is shorter, and has more strongly rounded sides; it is 
slightly narrower than the widest part of the elytra; it is ex- 
tremely like that of the species which I believe to be 
C. intercribrata, Fairm., in all respects except in the median 
channel being scarcely marked. The puncturation of the elytra 
is very much stronger than in C. caloptera, Boisd.

CYRIA. 
C. tridens, Blackb. In describing this species (vide supra, p. 
41) I omitted to mention its habitat, which is Richmond River 
District, N.S. Wales. Mr. French tells me that it is the insect 
on which the name C. gagates was founded. It is impossible to 
form a decided opinion on the point by reading the description— 
which does not even mention the colour of the elytra (unless the 
term “nigra” applied to the insect in general is to be strictly 
applied to every part except the eyes—in which case there would 
be no reason to connect C. éridens with it)—but I have no doubt 
Mr. French’s memory is trustworthy in the matter—and, indeed, 
I had thought of the question of identity with gayates when I 
described tridens ; but it is of little consequence, for, as far as I 
can ascertain, no description of C’. gagates has ever been published, 
the name occurring in a privately-circulated memoir of the late 
Rev. W. F. Hope. The species I named ¢ridens is certainly dis- 
tinct from C. wmperialis, Don., of which gagutes is said to be a 
variety. 
HYPOSTIGMODERA gen. nov. 
Gen. Stigmodere valde affinis; differt maris antennis biflabellatis. 
The extraordinary insect on which I found this genus seems 
to be a perfectly typical Stigmodera in all respects except that 
the antennz of the male are strongly biflabellate, resembling very 
closely those of the male in the Hiaterid genus Huphemus; the 
antenne of the female are those of an ordinary Stigmodera.
