by a sinus as in the allied Anthribide. The main anal vein and the veins forming 
the cell are well developed. As in the species of Scirtetinus there are also here no 
veins between the cell and the apex of the anal vein.

Genotypus: C. scotti, spec. nov. 
As the collection contains only a single specimen of this interesting genus, I have 
abstained from relaxing it for more minute examination. The structure of the antenna 
is so peculiar that there will be no difficulty in recognising the insect. 
The first two antennal segments are incrassate as usual in this group of genera, 
segment 3 is less than half the length of 2, but distinctly longer than 4, 4 to 6 are 
nearly alike, 7 and 8 are shorter, a little thicker and about as long as they are broad, 
9 resembles 8 except for being thicker, the club being formed by 10 and 11, which 
are rather hairy and somewhat flattened; 10 is rounded-triangular, bemg as broad 
as it is long, with the base nearly as broad as segment 9, 11 is three times as long 
as 10 and equals in length segments 2 to 5 taken together, being distinctly curved 
and of nearly even width throughout with the apex rotundate-angustate. 
The rostrum is more than four times as long as it is broad, being flat, with a 
feeble median depression ; its apical margin is slightly incurved. The antennal fovea 
is transverse and touches the eye. The latter is coarsely granulose and circular, with 
traces of two angles below. ‘The frons is very broad, being posteriorly wider than 
anteriorly. 
The prothorax and elytra are long and cylindrical, and bear dispersed short ap- 
pressed hairs, which do not conceal the colour of the derm to the slightest extent.

antennarum funiculo, tibiis tarsisque luteo-rufis, carina prothoracis lateribus valde

Long. (cap. excl.) 2 mm. 
One specimen, apparently a @. 
The antenna only reaches a little beyond the middle of the prothorax; segments 
1 to 5 are pale rufous, 6 to 8 rufous brown, 9 to 11 black. The pronotum is as wide 
as it is long, being widest at the apical fourth. It is minutely coriaceous and exceedingly
