epipleural lobes feeble ; surface distinctly punctate-striate, inter- 
stices slightly convex ; base and lateral margins narrowly, a broad 
sutural and a still broader discoidal band black ; the last band 
commences at the shoulders, curves inwards aud occupies the 
space between fourth and eighth row of punctures ; all the bands 
are abbreviated near apex.

2 • Flavous ; a spot on the vertex of head, two on thorax, 
humeral callus, margins and an abbreviated longitudinal band on 
each elytron, black. 
Head finely punctured, the middle with a fine groove ; a trans- 
verse band on top of vertex and the labrum black'; palpi flavous. 
Antennae ( $ ) fuscous, half the length of body, slender, third and 
fourth joints double the length of second, the fifth and following 
joints slightly widened. Thorax strongly narrowed anteriorly, 
posterior angles strongly pointed ; posterior margin deeply concave 
at sides, very narrowly black ; two spots placed close together on 
the middle of the disc, and an obscure short line at middle of base. 
Scutellum margined with piceous. Elytra distinctly punctate- 
striate ; interstices flat, shining ; the basal margins broadly, the 
other margins narrowly, black ; an elongate spot on shoulders, a 
longitudinal stripe abbreviated behind the middle on the third 
interstice likewise black. Pygidium and underside closely punc- 
tured, finely pubescent ; breast slightly darker. Prosternum very 
slightly produced anteriorly, posterior angles not pointed.

“ Much larger than C. vittipennis, the markings clearer and the 
elytral puncturation stronger.” (Suffr ian.) 
According to Weise C. sobrius is only the male of C. virgula , 
The 6 differs from the 2 in being smaller ; the oblique band of 
the thorax (in the banded form) is broad and parallel and unites 
sometimes with the opposite band, leaving only a triangular flavous 
spot between them iu front of scutellum. The elongate stripe 
of the elytra unites with the humeral spot in shape of a broad 
band, rounded posteriorly or dilated inwards as far as the suture. 
The markings of the thorax in the 5 ( virgula ) vary from two 
small spots to two broad bands, and the eljdral markings may 
either consist of a single spot above the shoulders or of another 
second spot on the third interstice of elongate, either narrowed or 
posteriorly widened shape.
