232 CHRYSOMELIDJE. 



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 and occupies the 

 space between fourth and eighth row of punctures ; all the bands 

 are abbreviated near apex.

$ . 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. Prosternura very 

 slightly produced anteriorly, posterior angles not pointed. 



Length 4| mm.

"Much larger than C. vittipennis, the markings clearer and the 

 elytral puncturation stronger." (Suffrian.) 



According to Weise C. sobrius is only the male of C. virgula, 

 The c? differs from the $ 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 in 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 $ (virgula) vary from two 

 small spots to two broad bands, and the elytral 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.
