T. Harfordi n. sp. — Moderately robust; black, antennae very slightly 

 piceous. legs dark piceous, tarsi paler, ttstaceous; integuments shining; 

 pubescence extremely fine, not very dense, longer, coarser and more promi- 

 nent on the abdomen. Head orbicular, as wide as long; sides behind the 

 eyes moderately convergent and rather strongly arcuate; occiput and base 

 strongly convex, very feebly and rather densely punctate; front nearly fiat, 

 finely and rather sparsely punctate, nearly impnnctate along the middle and 

 between the antennae; eyes rather large, not prominent; antennae verj' slen- 

 der, as long as the head, prothorax and one-half the elytra together, basal 

 joint distinctly more robust than, and equal in length to, the second, the 

 latter slightly longer than the third, joints four to ten equal in length, the 

 former scarcely twice as long as wide, the latter scarcely as wide as long, 

 eleventh about as long as the two preceding together. Prothorax widest at 

 one-third its length from the apex where it is as wide as long and distinctly 

 wider than the head; sides rather strongly convergent and arcuate to the 

 apex, and very slightly less strongly convergent and feebly arcuate to the base; 

 the latter broadly sub-truncate and very feebly arcuate, strongly arcuate n^nr 

 the basal angles which are broadly rounded; basal width three-fourths that 

 of the disk, and slightly greater than the apical; disk strongly convex near 

 the sides, broadly and distinctly impressed in the middle from the apical 

 third to very near the basal margin, where the disk becomes abruptly 

 declivous and convex to the ba=al edge; the latter is narrowly margined and 

 continuously so with the sides ; punctuation fine, strongly and acutely 

 asperate, evenly distributed and very dense. Elytra at base very slightly 

 wider than the pronotum; sides nearly parallel, feebly arcuate; together 

 truncate and strongly trisinuate behind; apical angles rather strongly pro- 

 duced, acute; disk scarcely longer tbau the prothorax, quadrate, rather 

 depressed, feebly impressed near the scutellum, rather finely, evenly and not 

 densely punctate; punctures sub-asperate, sparse and feeble near the outer 

 apical angles. Abdomen at base as wide as the pronotum; sides sub-parallel, 

 more strongly arcuate near the apex; punctures fine and leather dense, except 

 in the basal impressions, where they are very coarse: middle carinas obsolete; 

 border strong. Legs slender; posterior tarsi long and slender, first joint 

 much longer than the second but not as long as the next two together, longer 

 than the fifth. Length 2.8-3.0 mm. 



California (Sebastopol, Sonoma Co., 10). 



The sexual characters are very feeble, the sixth ventral 

 segment being rather strongly but very evenly rounded be- 

 hind in the male, and sub-truncate and slightly wider at 

 apex in the female. The elytral punctuation is slightly 

 coarser and distinctly more distant, though a little less 

 strongly asperate on the elytra than on the pronotum.
