2— Form stouter, convex, shining throughout, the head and prothorax with 
impressed close-set and rather feeble but distinct punctures, the elytra 
more coarsely, deeply, rather closely, subrugosely and conspicuously 
punctate, the abdomen finely, closely punctulate; head as long as wide, 
abruptly narrowed before the eyes, the front parallel and rectilinear at 
the sides; eyes prominent, at their own length from the base, the sides 
behind them rapidly convergent and arcuate to the neck; antennae rather 
more than half as long as the body; prothorax longer than wide, dis- 
tinctly narrower than the head, convex, the surface impressed at the sides 
behind the middie, the median line narrowly smooth and slightly ele- 
vated; elytra as long as the proithorax and a fourth or fifth wider, 
scarcely as long as wide, the sides subparallel and broadly arcuate, the 
base moderately oblique at the sides, with the angles obtusely rounded; 
abdomen parallel, feebly arcuate laterally, only slightly wider than the 
elytra. Length 3.8 mm.; width 0.68 mm. Virginia...monstrosus Lec. 
Form more slender, similar in color, lustre and sculpture to monstrosus but 
deeper black and less piceous; head longer than wide, less narrowed 
before the eyes, the latter less prominent but of the same size, the sides 
more strongly converging and arcuate behind them to the neck; anten- 
nae half as long as the body; prothorax narrower ard more elongate, 
only just visibly narrower than the head, otherwise nearly similar; 
elytra much narrower, smaller in size, fully as long as wide, barely as 
long as the prothorax and only about a sixth wider, the sides feebly 
diverging, feebly arcuate, the base very oblique at each side with more 
obtuse shoulder angles; abdomen relatively broader, parallel, arcuate 
at the sides, much wider than the elytra. Male with sexual characters 
nearly as in Stilicopsis, the fifth ventral feebly, subtriangularly emargi- 
nate throughout the width, the sixth also more strongly and parabolically 
emarginate throughout the width, the seventh with a broad slit, nar- 
rowing toward base, the ligula broad, flat and truncate; female with the 
sixth ventral very broad, obtusely rounded in circular arc at tip. 
Length 3.9 mm.; with 0.65 mm. North Carolina (Asheville). 
carolinae nD. sp. 
3— Body more parallel, shining, uniform and very pale in coloration 
throughout; head nearly as in monstrosus but more finely punctulate and 
similarly impressed at each side of the front before the eyes, the laiter 
rather smaller but equally prominent, at more than their own lergth 
from the base; antennae more than half as long as the body; prothorax 
as in carolinae; elytra parallel, arcuate at the sides, barely as long as 
wide, nearly as in monstrosus, as long as the prothorax and much wider; 
abdomen much narrower, parallel and almost straight at the sides and 
not wider than the elytra. Length 3.5mm.; width 0.6mm. Florida. 
pallidus n. sp. 
The conformation of the elytra is such as to suggest that 
the hind wings may not be fully developed in this genus,
