narrower than the apex ; the latter truncate ; apical angles obtuse, not 

 rounded ; disk one-third wider than long, finely, sparsely punctate, the 

 punctures larger and but slightly denser along the sides; impressions 

 distinct, feebly arcuate. Elytra quadrate, slightly wider and nearly 

 one-half longer than the prothorax, feebly impressed near the suture, 

 rather coarsely punctate, the punctures separated by twice their own 

 diameters. Abdomen parallel, slightly narrower than the elytra and 

 wider than the prothorax; sides very feebly arcuate; border moderate; 

 surface minutely and feebly reticulate, minutely and not very densely 

 punctate, iegs slender. Length 2.7 mm.

The head is rather smaller and the eyes less prominent than in 

 the following species. It appears to be common in the moun- 

 tainous regions of the Atlantic States. 



18 T, apac]ieanu§ n. sp. — Moderately robust and convex, black ; 

 legs piceous-black ; antennae piceous-brown, but very slightly paler 

 toward base ; pubescence very short, fine, and rather dense ; integu- 

 ments feebly shining, the abdomen subalutaceous. Head distinctly 

 narrower than the prothorax, feebly convex, finely, densely, and rather 

 strongly punctate ; antennae slightly longer than the head and pro- 

 thorax, slender; club gradual and feeble ; joints two to four uniformly 

 and slowly decreasing in length, the latter decidedly elongate and ob- 

 conical, tenth slightly longer than wide, obconical ; antennal promi- 

 nences strong; eyes large and prominent, moderately convex; tempora 

 short, one-fourth as long, obtusely angulate behind. Prothorax two- 

 fifths wider than long, widest at apical third, where the sides are evenly 

 rounded, and thence coarctate to the apex, and strongly convergent and 

 nearly straight to the base ; the latter feebly arcuate, nearly three- 

 fourths as wide as the disk and much narrower than the apex; the latter 

 transversely truncate ; apical angles obtuse, not rounded ; basal less 

 obtuse, slightly rounded ; disk rather finely, densely, and evenly punc- 

 tate throughout, the punctures separated by slightly more than their 

 own diameters ; impressions rather feeble. Elytra quadrate, distinctly 

 wider and one-half longer than the prothorax, each feebly impressed 

 along the suture, moderately coarsely, deeply and densely punctate ; 

 punctures separated by slightly more than their own widths. Abdomen 

 slightly narrower than the elytra, parallel; sides nearly straight; border 

 rather thick and shallow ; surface feebly convex, finely reticulate, mi- 

 nutely and rather densely punctate. Legs slender; tarsi moderate. 

 Length 3.0 mm.
