254 AMERICAN COLEOPTEKA. 



Cloudcroft, Sacramento Mts., New Mexico. A single female col- 

 lected by Mr. Knaus. 



In C. longula, a rare species of the Middle Atlantic States, the 

 fifth antennal joint is slightly transverse, the following joints increas- 

 ingly so, the thorax about as long as wide, with the sides nearly 

 parallel, the basal impressions obsolete or very faint. 



Carebara californica n. sp. — Intermediate in some respects between 

 longula and brevicoUis. The antennae are as in hrevicollis, prothorax less elongate 

 than in longula, but more so than in brevicoUis, being from three-fourths to four- 

 fifths as long as wide, the sides obviously convergent anteriorly, but less strongly 

 so than in brevicoUis ; basal impressions distinct. Elytra much shorter relative to 

 the prothorax than in brevicoUis, being very nearly three and one-sixth times as 

 long. Length 3.75-5.5 mm. 



California, San Bernardino Mts. (5000 feet). Common on pines 

 in midsummer. 



MORDELLID.E. 



JVIortlella fuscocinerea n. sp. — Eather slender, strongly cuneiform, 

 black, clothed uniformly above with sericeous brownish cinereous hair, the scu- 

 tellum slightly, the elytral suture not at all, paler. Beneath cinereous pubescent, 

 a piceous spot near the posterior margin of the hind coxal plate, and the ventral 

 segments fuscous posteriorly, especially at the sides. Length 3i-4i mm. 



Alamogordo, New Mexico (Viereck). 



Nearly allied to scutellaris, but narrower and more strongly 

 attenuate posteriorly, and of quite a different aspect because of the 

 much paler pubescence. The antennal and palpal structure is nearly 

 as in scutellaris. The .sexes differ only very slightly, the eyes being 

 a trifle larger in the male, the anteunse scarcely stouter or more ser- 

 rate in this sex, the outer joints (8-10) about as long as wide. 



Nordella perliiieata n. sp. — Elongate, moderately attenuate, disk of 

 elytra somewhat flattened ; black, prothorax varied with cinereous nearly as in 

 marginata, elytra with the suture and four narrow vittse on each cinereous, the 

 inner one extending only to the middle or slightly beyond ; beneath as in margi- 

 nata. Length 4-4i mm. 



New Mexico (Cloudcroft and Wootens), collected by Cockerell, 

 Knaus and Viereck. 



This species is most nearly related to oetopanetata and marginata, 

 but differs markedly from the latter in its more flattened dorsum, the 

 elytra being evidently less strongly arched wiien viewed in profile. 

 Tlie antennse are of the same type as in marginata but broader, the 

 median joints widest, a little longer and more evidently serrate in 

 the male, in which sex the outer sides (especially) of the joints bris-
