more convex spot, and the fifth ventral has a very small circu- 

 larly rounded median nick, the genital segment being flexed up- 

 ward in plane, with a large triangular apical emargination. Other 

 than the median nick, the fifth ventral of the assumed female is 

 rounded behind, and, as the antennae seem to be more slender 

 and the body larger in this specimen, — having the subapical 

 mirrors — it is probable that Dr. LeConte was correct in his iden- 

 tification of the sexes. Two specimens.

 (Melyris). 



There is no representative before me of either this species or 

 the next, but from some drawings and notes made from the orig- 

 inal types a few years since, it is apparent that atra is nearly 

 identical in sculpture and pubescence to speculifer and Jlavipes^ 

 but is rather narrower, more parallel and straighter at the sides 

 and a little more depressed ; legs as in speculifer. It differs de- 

 cidedly from both in the shape of the prothorax, which is more 

 rounded at the sides and widest at a much greater distance from 

 the base. Length 3.7 mm.; width 1.5 mm. 



Colorado (Beaver Brook— 6000 ft.),— Cab. LeConte. The female 

 is the onl}^ sex known. 



3. Ell. flaTipes Lee— Bull. U. S. Geol. and Geog. Surv., 1878, IV, p. 

 461 (Melyris). 



This species exactly resembles speculifer, but is smaller and 

 with the legs pale flavate throughout and a little shorter. The 

 hind tarsi are very nearlj'^ as long as the tibise. In sculpture and 

 vestiture it is similar to speculifer, except that the minute retic- 

 ulations of the elytra are more obliterated. Length 3.4-3.8 mm.; 

 width 1.3-1.6 mm. 



California, — Cab. LeConte. This species probabl}" does not 

 extend westward be3'ond the Sierras. 



RhADALIiN^. 



RHADAEIS Lee. 



In this genus the body is larger than in the preceding subfam- 

 ily, and clothed with long bristling pubescence. The ungual ap- 

 pendages are slender, equal, not as long as the claws and wholly
