46(5 TEETIARY INSECTS OF NORTH AMERICA. 



hudv is unfortunately broken across the elytra, which has given the draw- 

 ing an anomalous appearance. 



Length of body, 2.4 mni ; of antenna, 0.5 rai " ; breadth of body, 0.75""". 



Green River, Wyoming. One specimen, No. 106 (Prof. L. A. Lee). 



BRACHYTARSUS Schonherr. 

 BRACHYTARSUS PRISTINUS.

 Brach-ytarsiis pristinus Scudd., Bull. U. S. Geol. Geogr. Snrv. Terr., II, 87 (1876). 



The single specimen obtained is very poorly preserved and frag- 

 mentary. The head is roundish, with small circular eyes 0.08 mm in diame- 

 ter. The prothorax is subquadrate, considerably larger than the head and 

 nearly as broad as the body at the base of the elytra ; the latter are broken. 



Length of fragment, '2.l mm ; breadth of same, 0.84 mm ; length of head, 

 0.39 mra ; breadth of same, 0.4 nmi ; of thorax, 64 ram . 



Green River, Wyoming. One specimen, No. 15216 (F. C. A. Rich- 

 ardson).

CRATOPARIS REPERTUS.

A single specimen shows the fragment of an elytron, which is referred 

 to this genus from the character of the punctuation and the arrangement of 

 the stria?. It closely resembles C. lunatns Fahr. in these points, but must 

 have belonged to a slenderer insect, abou^ as large as C. lugubris Fahr. 

 There are eleven stria? or rows of pretty large, subconfluent, short, longi- 

 tudinal dashes or oval punctures, deeply impressed, the outer of which fol- 

 lows the extreme margin, excepting apically ; the inner stria also runs very 

 near the border; the interspaces between the first and second and between 

 the second and third stria? are equal and a little broader than the interspaces 

 between the other stria? ; the inner margin is delicately grooved next the 

 base, as in C. confusus.
