closely punctured, more closely on the sides and more finely in front; the median 

 carina narrow but elevated on the caudal two-thirds. 



The elytra are twice as long as wide, the bases nearly straight; the sides 

 nearly parallel to beyond the middle, then gradually arcuate, and somewhat 

 constricted just before the rather narrowly rounded caudal margin, as seen 

 from above, and very narrowly rounded at the apex; the striae well impressed 

 on the disc, the sutural striae widest and deepest, moderately, distinctly 

 impressed on the sides, wider than the narrow interspaces; the punctures very 

 coarse, deep, quadrate, close, small at the front margin, somewhat reduced on 

 the sides and declivity; the interspaces moderately convex on the sides, densely 

 rather coarsely rugose, and uniseriately, rather finely tuberculate behind. 

 The tibiae have a few moderately coarse teeth. 



The type is from the Cornell Collection, labelled Virginia; other localities 

 are Tennessee and District of Columbia. 



Hylastes nitidus, n. sp. 



A small, black, elongate species, very brightly polished; length, 4 mm.; 

 width, 1-3 mm. 



The head has the front evenly convex from the vertex to the epistomal 

 impression; minutely, rather closely punctured; the transverse arcuate 

 impression faint; the epistomal region very deeply abnormally impressed; the 

 median carina fine and faint extending to the transverse impression; glabrous 

 on the disc, with a few yellow hairs on the epistoma; the eyes very wide above 

 and very narrow below. 



The pronotum is one-half longer than wide, nearly as wide as the elytra, 

 broadly rounded behind; the hind angles rounded; the sides straight and 

 subparallel forward to the widest point which is beyond the middle, then 

 strongly narrowed to the rather broadly arcuate front margin; very finely, 

 rather closely punctured throughout, not roughened at the sides; the punctures 

 smaller at the sides and minute at the front margin; very brightly polished. 



The elytra are elongate, rather more than twice as long as wide, straight 

 arid acute at the base; the sides parallel to behind the middle, then gradually 

 evenly arcuate behind as viewed from above, narrowly rounded at the apex; the 

 striae distinctly impressed throughout, more strongly behind, the sutural strise 

 a little wider and deeper; the strial punctures of medium size, very deep and 

 closely placed; the interspaces moderately convex, more strongly behind and on 

 the declivity; brightly polished except on the declivity; minutely punctured 

 and somewhat coarsely sparsely roughened; densely granulate at the base; 

 very densely granulate, finely uniseriately tuberculate and dull on the declivity; 1 

 with very minute scale-like hairs on the declivity. The venter is polished, 

 sparsely, moderately punctured, the last ventral convex, coarsely, densely, 

 roughly punctured. 



The type is from Las Vegas, N.M., near Hot Springs, 7,000 feet. July, 82, 

 F. H. Snow. 



Hylastes asper, n. sp. 



A small dark brown species, somewhat similar to longus, Lee., but slightly 

 smaller, the epistomal carina distinct, the pronotum slightly shorter, the 

 elytral interspaces more convex and more strongly granulate. 



The head has the front convex, finely, closely granulate-punctate on the 

 disc, minutely, densely punctured on the vertex; the transverse arcuate im- 

 pression moderately deep; the epistoma broadly concave on each side; 

 the median carina acute, fine, from the epistomal margin to the transverse 

 impression; the pubescence minute, longer on the epistoma.
