COLEOPTERA OTIOKUYNCHIIKE. 4Ti) 



specimens of these species have been examined by me ; they are therefore 

 the most abundant fossils of the insect beds of the Green River shales. 



In the present species the snout is shaped much as in Otiorhynchus 

 perditus Scudd., being short, stout, and, especially anteriorly, arched, the 

 front border being 1 faintly angulate about the middN; : the antennal scrobes 

 can not be certainly defined ; the eyes are pretty large, transversely ovate, 

 and in most of the specimens are indicated on the stone by an annulus of 

 dark color, containing an interior narro\v ovate pale spot 0.22""" long by 

 0.12""" wide, while the eye itself is 0.4 mm in its longer, and 0.3""" in its shorter, 

 diameter; the facets of tin- interior portion are very minute, being scarcely 

 .01""" in diameter. The prothorax is somewhat tumid, rather higher than 

 Inn"-, verv profusely and delicately punctulate, the anterior and posterior 

 walls between the pittings often less elevated than the lateral walls, so that 

 the punctures often form broken longitudinal furrows ; the punctures arc- 

 nearly uniform in size over the whole prothorax and average about 0.04 mm in 

 diameter. The elytra are simple, not tumid, sloping off gradually toward 

 the tip, not elevated at base above the thorax, and provided with six equi- 

 distant, very slender and slight, raised ridges, faintly broken into dashes by 

 a series of minute, moderately distant punctures along the inner border of 

 each; these punctures are of the same size as those on the prothorax; the 

 ridges are about O.16 mm apart. The posterior coxa; have an incrassate pos- 

 terior margin. 



Length of body, 4 mm ; of rostrum beyond the eye, O.IJ8' nm ; width of 

 same, U.46 mm ; length of prothorax, 1.-2"" 11 : height of same, 1.3"""; length of 

 tegmina, 2.8""" : width of same, 0.0 mm .

Thirty-one specimens of this species have been examined sincethe first. 

 All those first obtained (by Mr. Richardson) were fragmentary, and most of 

 them rather obscure ; they consist mostly of side aspects of the creature, but 

 several an- single elytra. Still the characters drawn from them appear to 

 be all that can be found in the more perfect examples since found. The
