T. i]ni1)riatlis Lee. — Trans. Am. Ent. Soc, VI, p. 240. — Somewhat 

 robust, dark piceo-castaneous ; anteiinfe same ; legs slightly paler ; integu- 

 ments dull. Head fully as long as wide, very feebly and evenly convex, very 

 minutely and densely punctate ; tuberculations small and feeble ; transverse 

 suture fine, arcuate, distinct ; eyes moderate, feebly convex ; tempora feebly 

 arcuate, about as prominent and more than two-thirds as long as the eye ; 

 antenn£e as long as the head and prothorax, not very robust, feebly clavate, 

 second joint about twice as long as wide and scarcely as long as the next two 

 together, third slightly longer than wide, fourth and sixth very little wider 

 than long and but slightly smaller than the fifth, outer joints very slightly 

 transverse, the eleventh ovoidal, gradually pointed, two-thirds longer than 

 wide. Prothorax very slightly wider than the head, five-sixths wider than 

 long ; sides parallel, strongly, evenly arcuate ; base feebly arcuate, angles 

 very broadly rounded ; apex truncate or very feebly sinuate, the angles 

 slightly obtuse and not perceptibly rounded ; disk feebly convex, punctured 

 like the head, with two feeble, distant, basal impressions. Elytra not wider 

 and four-fifths longer than the prothorax, parallel, depressed, punctured like 

 the prothorax but rather more finely, the fine dense recumbent hairs so small 

 as to be not distinctly visible, the longer erect ones rather sparse and very 

 distinct. Abdomen nearly as wide as the elytra, more coarsely punctato-reti- 

 culate ; sides nearly parallel and straight ; border narrow and deep. Length 

 0.7 mm. 



Michigan (Detroit 1). Cab. LeConte. 



This species bears considerable resemblance to hesperius, but 

 may be distinguished by its more robust form, larger, wider pro- 

 thorax, and relatively shorter elytra. In the t^-pe, the abdomen is 

 drawn up so as to be very short, and the length given is therefore 

 less than the normal one for the species; the length given by 

 LeConte (0 5 mm.) is not correct. 



T. liesperillS u. spt — Slender, piceo-castaneous ; legs and antennje 

 throughout same ; integuments dull and dense. Head fully as long as wide, 

 rather feebly, evenly convex, very densely grannlato-punctate ; prominences 

 moderate in size, feeble; eyes large, feebly convex, very coarsely faceted, the 

 tempora not quite as prominent, feebly arcuate and scarcely more than one- 

 half as long ; antennse equal in length to the head and prothorax, moderately 

 robust, distinctly clavate, second joint oval, twice as long as wide, as long as 

 the next two together, third as wide as long, fourth and sixth equal, smallest, 

 distinctly transverse, fifth subequal to the third, outer joints feebly transverse, 

 eleventh ovoidal, pointed, two-fifths longer than wide. Prothorax very slightly 

 wider than the head, five-sixths wider than long ; sides parallel anteriorly and 

 distinctly arcuate ; base bi'oadly arcuate, coarctate with the sides through the 

 very broadly rounded basal angles ; apex broadly, feebly arcuate ; apical angles 

 slightly obtuse, not distinctly rounded ; disk feebly, evenly convex, punctate 

 like the head, with two small feeble impressions at the base, trisecting the
