A cast of an dvtron resembles so closely the elytron of O, perditus, 

 excepting in size, that it is referred to the same genus. Only nine stria; 

 can be counted, but all of those at the outer side may not be seen ; the 

 inner stria is very close to the margin, and indeed is lost in it both above 

 and below, but this may be due simply to the preservation. The stone in 

 which they are preserved is coarser than usual, coming from beds about 

 thirty meters directly below the shales which have furnished the other insect 

 remains, and has a greater admixture of sand: consequently the character 

 of tin- surface of the elytra can not be determined, but the stria- are sharp 

 and narrow, and lilled with longitudinal punctures, which do not show in 

 tlir engraving. With the exception of a couple of poor specimens of Kpi- 

 Cierus effossus Scudd., this was the only recognizable insect found at this 

 Locality.

A single specimen, preserved so as to show a lateral view of the insect, 

 appears to indicate an Otiorhynchid allied to Ophryastes. The form of the
