486 Coleopterological Notices, VI. 



This species is evidently allied to the preceding, but differs re- 

 markably in the sculpture of the el^'tra, these being also ver^^ 

 much shorter. The single male in my cabinet has the fifth ventral 

 short and broadly truncate at apex, but otherwise unmodified. 

 In both of these species the cilia along the sides margins of the 

 body are rather sparse and are unusually long for this section of 

 the genus.

Elytral pubescence whitish, \e\-y coarse, rather long, sparse 

 and apparently entirely unmixed with erect hairs. Antenute 

 short, stout, serrate, longer than the prothorax, incrassate, the 

 tenth joint only just visibly wuder than long. Legs and antennae 

 dark rufous ; posterior tarsi thick, fully as long as the tibiae. 

 Length 2.5 mm.; width 1.2 mm. 



California (San Diego) — Cab. LeConte. I am quite uncertain 

 as to the position of this species, since the type is' not before me 

 at present, and the published descriptions and short notes taken 

 b}' me some 3'ears ago are not sufficient. According to LeConte 

 the prothorax is gradually but strongl}- narrowed in front, with 

 the sides feebly arcuate and the hind angles obtusely rounded. 

 The el^'tra are coarsel}' punctured. The " last " ventral segment 

 of the male [fifth ?] is said to be longitudinally and broadly im- 

 pressed, which is ver}^ exceptional in this genus ; the sixth or 

 genital segment is however alwa3'S sulcate. 



19. T. sinmlaiD^ n. sp. — ^Eather stout, oblong, convex, black, the legs 

 pale rufo-feiTuginous throughout; antennae rufous, slightly obscure at the 

 apex ; pubescence rather long, very sparse but white and conspicuous. Head 

 barely two-thirds as wide as the prothorax, convex, finely, sparsely punctate, 

 l^olished and perfectly smooth throughout, the anterior impressions feeble; 

 epistoma short with the apical margin pale and coriaceous; labrum short and 

 broad, \\'idely rounded; mandibles pale externally; eyes moderately large but 

 scarcely prominent ; antennse stout, incrassate near the apex, but slightly 

 longer than the prothorax, the fifth joint dilated as usual, tenth distinctly 

 transverse. Prothorax short, fully two-thirds wider than long, the sides strongly 

 convergent and almost evenly, very feebly arcuate from base to apex, the latter 

 rectilinearly truncate and mtich narrower than the base, which is broadly, 

 strongly arcuate; angles at base and apex obtuse and rounded: disk highly 

 polished and perfectly smooth to the side margins, finely, sparsely punctate
