A single, very nearly perfect, elytron, broken slightly at tip- 1> 

 which belongs, with little doubt, to the Elateridre, is provisionally referred 

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

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

 tato-rugose, ami the striie are sharp and clearly defined. In nearlv all 

 Klaterid.-e the fourth stria from the suture unites with the third rather than 

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

 hypnus then.- appears to he more latitude, nearly any of the stria- un 

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

 the fifth some distance before the tip, while the first three run to th> 

 tremity of the el vtron, and the sixth, seventh, and eighth, following tip- 

 curve of the outer margin, terminate near the tip of the third >tria. 



Length of elytron, 5.5 mm ; breadth, 1.75 mm .

From the same locality were brought the remains of another in- 

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

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

 with the same part in Cryptoliypims planatus Le(J. that I refer it to tip- 

 fossil s| ..... P - above described, which its si/.e render-^ eiitiivK Me. It 



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

 about a third longer than broad, not including, of course, the side pi. 

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

 tate, more deii>elv and perhaps less deeplv next the coxal cavitie- ; the 

 median liip- (separating the two lateral halves of the whole iiietasternum ) 

 is very deep! v impr ------ I. but the furrow dies out anteriorlv in the' pn
