than wide, seventh slightly longer and thicker than the eighth, outer joints 

 rather longer tlian wide, the eleventh ovoidal, gradually pointed, twice as 

 long as wide. Prothorax slightly but distinctly wider than the head, one-half 

 ■wider than long ; sides parallel, evenly and rather strongly arcuate ; base 

 broadly, more feebly arcuate, angles very broadly rounded ; apex very feebly 

 emarginate, angles not at all rounded ; disk feebly, evenly convex, punctured 

 like the head and without distinct trace of impressions. Eii/tra quadrate, 

 parallel ; sides nearly straight ; disk just perceptibly wider and scarcely two- 

 fifths longer than the prothorax, excessively minutely and densely granulose, 

 the recumbent pubescence excessively short, silvery, the erect hairs distinct. 

 Abiiomen long and linear, very slightly narrower than the elytra ; sides straight 

 and parallel ; border moderate ; surface more coarsely and sparsely punctato- 

 reticulate ; punctures strong ; the apex of the sixth segment broadly feebly 

 sinuate in the middle, with the edge fringed with a close series of jiale porrected 

 membranous hairs, ie^s somewhat slender. Length 1.4 mm.. 



New York (near the city 1). Mr. W. Jiilich. 



This species' the largest of this section of the genus, approaches 

 very near to fiavicornis in general form, especially in its compara- 

 tively short elytra and large unimpressed prothorax ; it differs in 

 its much larger size, in its longer abdominal segments, in color, and 

 in its much more coarsely granulose and less abbreviated elytra. 

 In fiavicornis the elytra together are very distinctly wider than 

 long, while in the present species they are quadrate. 



T. Iliaci'OpterilS Lee. — Trans. Am. Ent. Soc.,VI, p. 241. — Rather robust, 

 piceous-black throughout the body, legs and antennas ; integuments very dull, 

 the minute recumbent pubescence of the anterior portions fulvous, the sparser 

 suberect hairs cinereous. Head as long as wide, rather small, feebly convex, 

 minutely, very densely punctate, the punctures not completely coalescent and 

 rather distinctly definable ; eyes rather large, the tempora not as prominent 

 and less than one-half as long ; tuberculations feeble ; antennae distinctly 

 longer than the head and prothorax, moderately robust, distinctly clavate, 

 second joint rather more than twice as long as wide and nearly as long as the 

 next two together, third much less robust, elongate, nearly twice as long as 

 wide, fourth very slightly longer than wide, slightly longer and less robust 

 than the sixth, the latter very slightly transverse, fifth more robust, distinctly 

 longer than wide, outer joints very slightly transverse, eleventh more robust, 

 ovoidal, abruptly pointed, one-half longer than wide. Prothorax nearly one- 

 third wider than the head, two-thirds wider than long, almost semicircularly 

 rounded behind from the middle of the sides, the middle of the base less 

 strongly arcuate ; sides before the middle slightly convergent ; apex strongly, 

 evenly sinuate throughout the width, angles not at all rounded and very dis- 

 tinct ; disk rather more finely sculptured than the head, granulose, evenly, 

 feebly convex, without trace of impressions. Elytra one-third wider and four- 

 fifths longer than the prothorax ; sides parallel and distinctly arcuate ; surface
