cJdtidce, and at least very rare in the allogastral RhyncopJiora, to which 

 one would at first glance refer this fragment. So far as the material at 

 hand permits determination, it appears to agree best with the genus to 

 which it is referred, on account of the disposition of the punctuation 

 and the form of the tip of the elytron. It represents, however, a very 

 large species, and one whose punctuation is very delicate. The elytron 

 is long and rather narrow, indicating an elongated form for the body, as 

 in this genus, with parallel sides and a bluntly rounded tip. There are 

 ten complete equidistant rows of delicate, lightly impressed punctures, 

 those of the same row less distant than the width of the interspaces ; the 

 outer row lies close to the outer border and is seated in an impressed 

 stria, as also is the apical half of the inner row ; but the other rows show 

 no such connection between the punctures which compose them ; at the 

 base the rows curve very slightly outward to make place for a very 

 short humeral row of punctures, parallel to the inner complete row, and 

 composed of only three or four punctures on the part preserved; the 

 interspaces are smooth. 

 Length of fragment 4.5""™ ; width of elytron 1.5""".

Epicwrus saxaiilis Scudd., Bull. U. S. Geol. and Geogr. Surv. Terr, ii, 

 84-85 (Eudiagogus). — Twenty-seven specimens of this species have been 

 found by Mr. Eichardson, Mr. Bowditch, and myself. This and the 

 two following species cannot be referred to Eudiagogus on account of 

 the length of the snout. Although very small for Epicccri (especially 

 the present species), they agree so well with Epiccerus griseus Schonh. 

 from Mexico — one of the smallest of the group — that they would best be 

 referred here, although they differ from this genus in the brevity and 

 stoutness of the femora, all of which are swollen apically. It is possible 

 that all three of the forms mentioned here should be referred to a single 

 species, as there is certainly very little difference between them except- 

 ing in size ; this is particularly the case with this and the next species. 

 Together over one hundred of these species have been examined by me ; 

 they are, therefore, the most abundant fossils of the insect beds of the 

 Green Eiver shales. 



Epiccerus effossus Scudd., Bull. U. S. Geol. and Geogr. Surv. Terr, ii, 

 85-86 [Eudiagogus). — Nearly fifty specimens of this species are at hand, 

 all found in Richardson's shales by Mr. Eichardson, Mr. Bowditch, and 

 myself, besides two I found in beds at the same spot, but about thirty 

 metres lower ; these were the only Goleoptera found at that spot, except-" 

 ing a single specimen of Otiorliynclius duhius Scudd., belonging to the 

 same family. 



Epicmrus exanimis Scudd., Bull. TJ. S. Geol. and Geogr. Surv. Terr, ii, 

 58 {Eudiagogus). — Thirty-one specimens of this species have been ex- 

 amined. 



Ophryastes compactus. — A single specimen (No. 4210), preserved so as
