498 Guleopterological Notices, VI. 



slightly longer than the prothorax, the three last joints distinctly broader, the 

 tenth strongly transverse; eyes moderately large, prominent, at about one-half 

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

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

 tuse; apex truncate in the middle, broadly and posteriorly oblique and 

 rounded laterally, and fully as wide as the base or rather wider; disk very 

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

 fifths longer than wide and about two-fifths wider than the prothorax, parallel 

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

 rounded and quite 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-canaliculate along the middle. The description applies 

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

 fifth and sixth joints completely 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 entirel}^ red, and 

 differing especially in its shorter and finer el3'tral pubescence and 

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

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

 view of the peculiar sexual differences in the following species. 



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

 throughout altove and beneath ; scutellum, legs and antennje concolorous, the 

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

 cence rather long, moderately sparse, decuml)ent, 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; epistoma rather long, a wide 

 apical margin yellow and subcoriaceous ; labrum 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 sulx-onical, 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 much narrower than the base; punctures not very fine or 

 .sparse and somewhat unevenly distrilnited ; pubescence conspicuous. Elytra 

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

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