A single, very nearly perfect, elytron, broken slightly at the base, 

 which belongs, with little doubt, to the Elateridaj, is pi'ovisionally referred 

 to this genus. The form of the elytron is as in C. planatus LeC, which is 

 slightly larger than the fossil species. The surface is very minutely jiunc- 

 tato-rugose, and the strite are sharp and clearly defined. In nearly all 

 Elateridse the fourth stria from the suture unites with the third rather than 

 with the fifth, although it often runs independently to the tip. In Crypto- 

 hypnus there appears to be more latitude, nearly any of the striae uniting 

 with either of their neighbors ; and in this species the fourtli unites with 

 the fifth some distance before the tip, while the first three run to the ex- 

 tremity of the elytron, and the sixth, seventh, and eighth, following the 

 curve of the outer margin, terminate near the tip of the third stria.

 men, No. 59 (Dr. G. M. Dawson). 



From the same locality were brought the remains of another insect, 

 consisting of the metasternal plates, one side complete, the other broken, 

 and plainly belonging to the Elateridse. The perfect side agrees so well 

 with the same part in Cryptohypnus planatus LeC. that I refer it to the 

 fossil species above described, which its size renders entirely admissible. It 

 is, however, relatively longer than in C. planatus, the perfect half being 

 about a third longer than broad, not including, of course, the side pieces* 

 which are not preserved. The surface is densely and rather heavily punc- 

 tate, more densely and perhaps less deeply next tlie coxal cavities; the 

 median line (separating the two lateral halves of the whole metasternum) 

 is very deeply impressed, but the furrow dies out anteriorly in the projec- 

 tion between the coxae.
