COLEOPTERA— CARABID^. 517 



striae and flatter interspaces than any known to me. In general, in color 

 and in texture, excepting in the very interruptedly elevated and gibbous 

 interspaces, which are the chief characteristic of the elytra of H. tubercu- 

 latus Gyll., it might be compared to that species, but it agrees better in 

 size with H. scaber LeC. The prominent humeral angle is not properly 

 shown in the plate, and the breadth is made to appear too great from the 

 spreading of the declivous mai-gin 



Length of fragment, 2.1°""; probable length of elytron, 2.25°""; breadth 

 in natural position, 0.7'""".

A fragment of a leg found by Mr. Denton in Fossil Canon, White 

 River, Utah, must be referred to this genus. It represents the hind femur 

 and tibia of a species allied to L. maculosus Germ , but is so uncharacter- 

 istic a fragment that it is not worthy of further mention.

"One elytron of the size and very similar to that of C. laticollis, from 

 which it differs in having the striae more finely impressed and the punctures 

 rather closei', while those of the intervals are coarser and less numerous. 

 Length, .40 inch; 10""". 



"There can be no doubt that the generic determination is correct in 

 this instance." Horn, loc. cit.
