Ohio, Dr. Kirtland. Very similar to the preceding ; the sides of the thorax 

 are more suddenly reflexed, and the disc is channeled ; the basal elevation on 

 each side is broader and less sudden, rather a line than a tubercle, and the 

 elevated lines of the elytra are scarcely visible.

 marginibus subreflexis pallidis, punctatis, disco versus basin late foveato, cum

 elytris grossius granulato-ptinctatis. Long. '25. 



Georgia, in Habersham county. The antennsc are as broad as in L. atra, and 

 in the same manner are shorter in the female than in the male. The basal 

 angles of the thorax are almost always dark colored ; the discoidal spot is 

 sometimes almost disconnected with the base.

'J'he first division of this genus approaches very closely in form to the last, 

 and is distinguished only by the form of the last superior abdominal segment, 

 and the absence of any light giving spot. The males are distinguished by the 

 additional anal segment, which, with the preceding, is protected by the large 

 superior segment.

Abundant everywhere; the thoracic spot is sometimes obsolete. The granu- 

 lation of the elytra is much finer than in the next species. The margin of the 

 thorax is commonly fuscous but is sometimes pale. 



2. E. d e c i p i e n s , fusco-nigra, thorace apice rotundato, basi truncato, 

 lateribus subsubito reflexis, roseo-testaceis, cum apice scabris, disco obsolete 

 carinato, ante basin transversim impresso, elytris confertim minus subtiliter 

 granulatis. Long. '25.

Northern and Southern States; the elytra have two slightly elevated lines. I 

 have one specimen from Georgia in which there is a wide impression at the 

 middle of the thorax and the carina is wanting, it may possibly be a distinct 

 species, but in such an obscure family I am unwilling to separate it on a single 

 specimen.
