Massachusetts. The last ventral segment in the o is 
broadly and feebly emarginated, and the front tarsi dilated. 
Another species of the same group of the genus, which has 
not been thus far represented in our fauna is: 
36. Quedius vernix, n. sp.—Less elongate, narrower in front and 
behind ; black, very shining, antenne, palpi, and legs also black. Head 
oval, moderately constricted at base, neck rather thick, punctulate each 
side; space behind the eyes, and extending beneath to the lateral line 
finely punctured ; sub-ocular punctures two, supra-oculars also two; each 
side near the anterior one is one small puncture, and behind the posterior 
one, on the occipital declivity is another large one. Prothorax scarcely as 
long as the basal width, narrowed in front, sides rounded, apex emarginate, 
base strongly rounded ; apical punctures three on each side ; discoidal but 
one ; lateral one, large, situated near the margin, and one-fourth the length 
from the front angle; there are but two small basal punctures, in the 
margin itself, the outer one at the much rounded hind angle. Scutellum 
large, smooth. Elytra smooth, sutural stria deep, with a puncture in front 
of the middle; dorsal series of 4 or 5 large punctures. Dorsal segments 
very sparsely punctured and pubescent, sides and apex with long sete ; 
ventral segments equally, sparsely punctured. Length 12 mm.; .48 inch. 
Massachusetts, Michigan, Canada, rare. The front tarsi 
are dilated in both sexes; the last ventral segment is longer, 
and scarcely perceptibly emarginate in the &. 
37. [5]. Cryptobium fioridamum, n. sp.—Shining, hairy, with 
erect pubescence, black, becoming brown towards the tip of the abdomen, 
antenne brown, legs paler. Head as long as the prothorax, and wider than 
it, oblong, somewhat narrower in front of the eyes, which are convex and 
moderately prominent ; base and hind angles rounded, surface strongly 
punctured, front nearly smooth. Prothorax one-half longer than wide, 
smooth dorsal stripe broad, sides strongly punctured, the punctures form- 
ing in places short irregular series. Elytra longer than the prothorax, 
strongly rather denscly punctured. Abdomen, dorsal surface finely and 
sparsely punctured ; ventral surface similarly punctured. Length 10.4 
mm.; .41 inch. 
2 Second and third ventral segments with a short transverse groove, 
bearing stiff setee. 
Enterprise, May; one specimen. This species is similar 
in form and seulpture to C. badium, but the color is different, 
and the 3d apparent ventral segment (2) has a transverse 
fold similar to that of the 2d. In C. carolinum the second 
ventral segment has (2) a transverse fold, with a row of stiff
