from anv at present existing, but it may be inferred that it is the species to 

 which our vidims must look for its ancestry. 



"1 have named the species in honor of .Mr Charles .M. Wheatley, of 

 Phu-nixville, to whom we are indebted for the exploration ot' the locality in 

 which the lo^il insects were discovered." Horn, loc. fit. 



Including the striae next the margins of the elvtra there appear to be 

 fourteen in all ; the two outer ones are obscure and those upon the disk are 

 at an average distance apart of 0.37")"' ; the >t ri.-e appear to be faintly punct- 

 ured and the punctures as distant as the stria 1 ; the intervals between the 

 stria> are broken by irregular impressed lines producing a tuberculate ap- 

 pearance but otherwise smooth. The disk of the prothorax is considerably 

 more quadrate and proportionally broader than in the species of (..'ychrus 

 with which Dr. Horn compares it. Indeed, I was at first inclined to believe 

 that the lateral lamellate rim was narrow and equal throughout, and there- 

 fore to place the insect in Calosoma (in the neighborhood of the species 

 sometimes referred to Callisthenes) ; but a renewed study in company with 

 Dr. Horn shows that this is a mistake, and that the rim broadens great Iv 

 behind, leaving a somewhat shield-shaped disk as in Cychrus viduns.

" Two fragmentary elytra of smaller size than the preceding [C 

 wheatleyi] afford the only groundwork for the name above suggested. 

 The striae are fine and with tine punctures, the intervals feebly convex, 

 evidently slightly rugulose, and probably, also sparsely pnnctiilate An 

 impression of the scutellum remains which is broadly triangular, and not 

 different in form from that ofandrewsii.
