slifihtly longer than the jnotliorax, the three hist joints distinctly broader, the 

 tenth strongly transverse; eyes moderately large, prominent, at ab<mt one-half 

 their length from the base. Profhomx one-half wider than long, widest and 

 rather prominently ronnded at tlie sides just behind the middle; angles ob- 

 tuse; apex truncate in the middle, broadly and ])Osteriorly oblique and 

 rounded laterally, and fully as wide as the l)ase or rather wider; disk very 

 finely, sparsely punctate, slightly rugose toward the sides. Elytra short, two- 

 fifths longer than ^\•ide and about two-tifths wider than the prothorax, parallel 

 and straight at the sides, very broadly and obtusely rounded at apex ; humeri 

 rounded and (^uite distinctly exposed at base; punctures fine and rather dense. 

 Abdomen distinctly but not very densely cinereo-pubescent, the legs slender. 

 Length 1.8 mm.; width 0.75 mm. 



Arizona. 



The male has the fifth ventral truncate at apex, the genital seg- 

 ment with a broad cuspiform apical emargination and broadly 

 impresso-canaliciilate along the middle. The description applies 

 to the unique male type. The left antennae of the type has the 

 fifth and sixth joints completel}' fused, with the division repre- 

 sented only by lateral notches ; antennal malformations appear to 

 be very common in this genus. 



I have before me a single female, also from Arizona, having 

 similar coloration, except that the abdomen is entirely red, and 

 differing especially in its shorter and finer elytral pubescence and 

 very much more elongate epistoma ; it seems to represent a dis- 

 tinct species Avhich it is not advisable to describe at present, in 

 view of the peculiar sexual differences in the following species. 



36. T. testaceiis n. sp. — Oblong, convex, shining, pale luteo-testaceous 

 throughout al)ove and l)eneath; .scutellum, legs and antennae concolorous, the 

 extreme tip of the eleventh joint of the latter blackish; eyes black; pubes- 

 cence rather long, moderately sparse, decumbent, ashy and conspicuous al- 

 though not very coarse, rather unevenly disposed on the pronotum. Head 

 scarcely three-fourths as wide as the prothorax, coarsely and somewhat closely 

 punctate, the interspaces smooth and polished, a convex median area toward 

 apex impunctate; impressions extremely feeble; e])istoma rather long, a wide 

 apical margin yellow and subcoriaceous; lalnum small, arcuate at tip; eyes 

 moderately large, very near the base and only slightly prominent; antennae 

 distinctly longer than the prothorax, the tenth joint transverse, fifth dilated. 

 Prothorax subconical, not more than two-fifths wider than long, the sides 

 rather strongly convergent and very feebly arcuate from base to apex ; angles 

 very obtuse; apex mvich narrower than the base; punctures not very fine or 

 sparse and somewhat unevenly distributed ; pubescence conspicuous. Elytra 

 one-half longer than wide, two-fifths wider than the prothorax, iwirallel and 

 nearly straight at the sides, very obtusely and somewhat individually rounded
