 obscure rufescentibus. Long. 5^ lin. $ . 



Hiogo, three examples. 



Of the same ashy-green colour as C. 4-punctatus, F., but of 

 much narrower and more cylindrical form. The antennae are 

 slender and half the length of the body in the female. The 

 thorax is long, very gradually naiTOwed in front and abruptly 

 narrowed near the base. The elytra are sharply and obliquely 

 truncated, with the exterior angle dentiform ; each has, behind 

 the middle, two transverse black spots, the first a little after 

 the middle, and the second nearly midway between the first 

 and the apex ; near the base there are also two small black 

 specks, one near the scutellum, the other on the humeral callus. 

 The legs are long and slender ; and the hind femora reach the 

 tips of the elytra.

Smaller and much narrower than C. massiliensis, Linn. , 

 more cylindrical. Antennae filiform, as long as the body;

 than in front, closely punctm-ed ; the base on each side bor- 

 dered with light grey. Scutellum black. Elytra cylindi-ical, 

 transversely truncated, exterior angle dentiform ; a sutural 

 spot behind the scutellum, a discoidal spot behind, a fascia
