AMERICAN COLEOPTERA. 75 



joiat of the antennge, the more rounded sides to the thorax and the 

 shape of the jugular processes, which are very much less curved in- 

 wards towards each other in the American species. 



I^ii^conotHS? linearis, n. sp. — Elongate linear, not very convex, 

 pitchy brown, clothed with a tolerably dense golden pubescence ; head broad, 

 scabrous; thorax longer than broad, front angles acute, sides crenulate, 

 straight, narrowed slightly towards the base, disc scabrous, with two shallow 

 fovesE towards the base, which is strongly margined : elytra each with five 

 slightly raised lines, intervals with two rows of rather deep punctures, base 

 and subapical spot rufous; body beneath opaque, punctate. L. 2.7 mm. 



Under bark of Sycamore or some small forest tree at the Hot 

 Springs in the Sta Inez Mountains. The little genus Ozojnathu^/Wd'i 

 excessively cojimon in the same bark. This species agrees with Las- 

 coiiotus in the 3-jointed club, but has the sculpture and appearance 

 of Si/nchi/todcii\_Ditoma']; it should probably form a separate genus, 

 which may be compared with lllestus Pascoe. 



Oxylsemus caliTornicus, n. sp.— Elongate, cylindrical, dark red, 

 finely pubescent; head punctate; thorax elongate, very coarsely punctate, 

 with a smooth medial line and well marked basal impression near the hind 

 angles; elytra punctate-striate, interstices smooth; prosternal epipleuree ru^u- 

 lose, ventral segments coarsely punctate. L. 3.5 mm. 



Calaveras, Sierra Nevada. 



Tl'OgOi^ita yuccae, n. sp.— Elongate, dark pitchy brown, legs paler; head 

 finely subrugulose, sparingly punctate, a short impressed frontal medial line, 

 anterior edge deeply tridentate; thorax about as long as broad in front, sides 

 almost straight at first, then rapidly obliquely narrowed towards the base, 

 sides and base strongly margined, hind angles very obtuse, sculpture as on 

 head; scutellum transverse, very small, elytra margined at base, with rows of 

 impressed punctures, intervals flat, also with rows of finer punctures, at the 

 apex a small sutural stria is indicated; beneath brownish, prosternum with a 

 few deeply impressed punctures. % mentum with a fulvous tuft of hairs. L. 

 19 mm. 



Under bark of the tree Yuccas on the Mojave desert in May. 

 Apart from the color it may be noticed that the eyes are more strongly 

 granulated than in T. vh-escens. 



Differs from T. harhata by much more sparse punctuation of head 

 and thorax and very weak punctures on the elytra, 



ColasttiS yuccse, n. sp.— Broad, depressed, opaque, black, pubescent, 

 closely subrugulosely punctate throughout; thorax broader than long, feebly 

 emarginate in front, front angles rounded, sides and base margined, the former 

 broadly rounded, as are also the hind angles, base feebly sinuate in front of 

 the scutellum ; elytra with the sides acutely margined ; pygidium sculptured 

 as the rest of the upper surface. L. 5 mm.
