bly constituting a moderately large genus, are unquestionably much 

 less numerous than those of Lachnosterna. 



The two following species have been received since my last refer- 

 ence to the genus: — 



T. 'blaiHdelli n. sp. — Robust, moderately convex, form nearly as in 

 fossifjer, rather shining, pale rufo-castaneons in color, the humeri and under 

 surface blackish ; vestiture pale ochreous in color. 



Male. — Head, excluding the eyes, subquadrate, but slightly wider than 

 long, very densely clothed with short robust pubescence and long erect hairs ; 

 clypeus moderately reflexed, very feebly sinuate, the angles broadly rounded; 

 antennje moderate, the club slender, straight, a little shorter than the stem ; 

 fourth joint of the maxillary palpi unusually robust, oval, twice as long as 

 wide, about three-fourths as long as the antennal club, the groove wide, deep, 

 extending from base to apex, two and one-half times as long as wide, the 

 bottom broadly, evenly concave and alutaceous in lustre. Prothorax two-thirds 

 wider than long, broadly lobed at base and subangulate at the sides, some- 

 what coarsely and densely punctate, clothed rather densely with robust 

 squamiform pubescence and fine, moderately long erect hairs. Scutellum 

 densely punctate and squamose. Elytra about one-third longer than widti 

 and nearly one-half wider than the prothorax, the apex broadly subtruncate ; 

 sides feebly arcuate ; humeral callus rather prominent ; disk shining, moder- 

 ately densely and unevenly punctate and subrugulose, the punctures some- 

 what strong, the vestiture consisting of short recumbent moderately densely 

 placed hairs, which are robust but not at all squamiform. Pygidium finely, 

 densely punctate and clotlied like the elytra. Abdomen finely, densely punc- 

 tate and very densely squamulo-pubescent, the vestiture whiter than that of 

 the upper surface ; sterna with the usual long silken pile. Legs rather 

 short, the posterior tarsi distinctly shorter than the tibiie ; ungual teeth of the 

 corresponding tarsi vei'y unequal, the anterior twice as long as the posterior. 

 Length 20.0-23.0 mm. ; width 9.4-11.0 mm. 



California (Coronado, San Diego Co.). Dr. F. E. Blaisdell. 



This species, which is represented by the male only, is somewhat 

 allied to fossiger, but differs in its more robust and less densely 

 placed elytral vestiture, shorter, much broader terminal joint of the 

 maxillary palpi and in its shorter posterior tarsi. 



I have before me a female, pale brownish-rufous in color, strongly 

 shining throughout, with the elytral pubescence excessively fine 

 and sparse, much shorter and finer than in squamicollis, but about 

 twice as dense as in that species. It was taken at Los Angeles and 

 probably represents still another species which it would not be 

 advisable to describe in the absence of the male. It may possibly 

 be the female of the present species.
