This is the only genus we have of this small subfamily, 
and it may be easily known by its ventral stigmata and the 
long cheeks, as well as by the sharp foliaceous sides of the 
pronotum. In form it is almost regularly elliptic, the 
cheeks are almost as long as the central lobe of the face, 
the antenne are short, with the basal joint stout and short, 
and the second about twice as long as the third, the antenni- 
ferous tubercles are small and inferior, the eyes not 
prominent, rostrum reaching to the intermediate coxze ; 
pronotum subtrapezoidal, lateral margins foliaceous; scu- 
tellum impressed, abdominal stigmata ventral, legs simple. 
There is only one European species. 
C. typhe, Perris.—Flat, ochreous, glabrous, shining, 
strongly punctured. Head across the eyes, not so wide as 
the anterior margin of the pronotum; antennz brown ; 
there are two impressed dark streaks down the face ;

ocelli very strongly developed; anterior margin of the 
pronotum emarginate, sides somewhat sinuate, base very 
slightly and very widely emarginate, disc largely and 
irregularly punctured with black, impressed along the 
sides ; scutellum with a central dark impression, which is 
deeply punctured ; elytra flat, punctured with black, the 
nerves much raised and pale, membrane whitish with a 
darker central cloud; abdomen reddish ochreous, black at
