sunk between the prominent and somewhat acute humeral angles 
of the elytra to its lateral angles which are obtuse. This species 
is probably near Coptocycla Holmgreni, Bohem., but I judge from 
the description of that insect that inter alia it differs much from 
the present one in color and marking.

C. maxyma, sp. nov. Scutiformis; nitida; valde convexa ; 
pallide testacea, antennarum parte apicali nigra, elytrorum 
parte discoidali rufescenti nigro-variegata ; antennis fere ad

The markings on the convex discal portion of the elytra are as 
follows :—On the retuse portion in front some inconspicuous 
blackish clouds, a linear interrupted blackish marking or series 
of marks running obliquely from the humeral callus to the suture 
at about its middle, an irregular blotch of blackish color near the 
apex of the suture which is obsoletely continued along the 
suture to its actual apex (on the explanate border). The form 
of the prothorax is peculiar; at either extremity of the front 
(evenly curved) outline (which represents I suppose the front and 
lateral margins) the outline is sharply rectangular; from this 
angle the prothorax narrows strongly hindward, its outline on 
either side being nearly an oblique straight line; this straight 
line at its hind extremity merges without a defined angle into 
the sinuate horizontal base which in the middle is moderately 
lobed hindward. The gibbosity behind the scutellum (in reality 
it includes the scutellum) is very pronounced (amounting to a 
large conical protuberance), the front slope of which bears a 
large deep fovea on each elytron. The explanate margin of the 
elytra is very wide, being at its widest part scarcely narrower 
than the interval between its inner margin and the suture. The 
fourth joint of the antenne distinctly longer than any other 
joint except the first and eleventh is a very distinctive character. 
The appendiculation of the claws is, even more markedly than in
