OOLEOPTERA— OTIORHTNCHID.E. 477 



In the geaeral sculpturing' of the elytra this insect is not very unlike O. 

 sulcatus (Fabr.).

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

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

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

 inner stria is veiy 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 the surface of the elytra can not be determined, but the striae ai"e sharp 

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

 the engraving. Witli the exception of a couple of poor specimens of Epi- 

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

 locality. 



Length of elytron, 4""; breadth of same, 1.5"". 



Dr. E. Bergroth having called my attention to the fact that there is a 

 recent European species of Otiorhynchus bearing the specific name dubius, 

 I have renamed the fossil as above.

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
