Indiana, Kentucky and Iowa. This species has been well de- 

 scribed by LaFerte', though I have never seen an example ia 

 which the punctures are completely confused toward the elytrali 

 base ; it is especially abundant in the Mississippi valley, while' 

 the following is the common species along the Atlantic coast. 

 The fifth ventral in the male is short, onl}' one-third longer than 

 the fourth, narrowly subtruncate at the middle of the apex, the 

 edge thence oblique and straight nearly to the sides, then rounded 

 to the base, the genital segment large and broad, pale and sub- 

 coriaceous, transversely convex throughout the width and sub- 

 truncate at apex. In the female the fifth ventral is much longer, 

 two-thirds longer than the fourth, and is evenly rounded in cir- 

 cular arc throughout.

Similar to the preceding in general form and sculpture, but 

 with the elytra a little shorter and stouter and pale only in basal 

 third or fourth, with the punctures very fine, becoming abruptly 

 coarse and more distinctly seriate in the pale area. Length 2.4- 

 2.7 mm.; width 0.8-LO mm. 



New York, Rhode Island and Michigan. The male has the fifth 

 ventral full}' three-fourths longer than the fourth, transversely 

 truncate in median fourth at apex, the edge thence oblique and 

 straight to near the sides, then gradually rounded to the base, the 

 genital segment transversely, evenlj^ convex and truncate at 

 apex, nearly as in interruptus. In the female the fifth venti'al 

 is fully three-fourths longer than the fourth, and is evenly and 

 somewhat parabolically rounded behind. 



3. T. inipressillllS n. sp. — ^loderately stout, convex, highly polished, 

 the head and pronotum siibimpunctate and clothed very sparsely with fine sub- 

 decnmbent hairs, the elytra finely, sparsely but distinctly punctate, the punc- 

 tures becoming rather gradually coarse and more distinctly seriate in arrange- 

 ment toward base, with the pubescence moderate in length, suberect, coarse 

 and rather dense; body dark rufo-testaceous, piceous-black beneath, the abdo- 

 men paler at apex; head darker; legs and antennie jiale flavo-testaceous, the 

 latter gradually darker or more rufous toward base; elytra varying from 

 rufo-testaceous to piceous-black throughout, sometimes just visibly and very
