40 COLEOPTERA. 



river-banks, living under stones and in the roofs of plants, 

 especially of Triticum 7'epens, on which, according to Lacor- 

 daire, its larva feeds. And it is even recorded from 

 America. 



This most variable species is about the size of 4'pustulatus 

 (perhaps a little larger) ; its elytra are strongly striated (the 

 striae, however, being sub-obsolete at the apex), with the 

 interstices almost keel-like as far as the middle ; and, in the 

 type-form, are ornamented with a whitish-yellow trilobed 

 spot at the base (composed of two humeral spots and a scu- 

 tellar line), another rounded spot below the middle and some 

 smaller spots, or a larger bifid mark at the apex. A com- 

 mon var. seems to have the spots running into the shape of 

 X on the back ; but Candeze states it would be impossible to 

 enumerate all the combinations of markings afforded by this 

 insect. 



Its thorax has the posterior angles slightly divergent, with 

 the raised keel that commences at the angle running parallel 

 to the lateral margin as far as the middle, and the disc sub- 

 rugosely punctured. The legs are entirely yellow.

p. 100. 



Dr. Sharp records the capture by himself of twelve 



examples of this rare species on the banks of the Nith, 



Thornhill, and of two specimens by Mr. Lennon on the 



banks of the river at Dumfries. Hitherto it appears only 



to have occurred in Sweden. It is very closely allied to 



C. jmlchelhis, but appears to be separable from that species 



by its much larger size ; by its longer thorax, of which the 



posterior angles are shorter and not in the least degree
