to be separated only by slight differences ın the proportion 
of the joints of the antenne, and the punctuation of the 
elytra.

A. gilensis Lee. does not seem sufficiently distinct from A. 
pronus Er. 
Mr. Fauvel (Faun. Gallo-Rhen. iii, 542) states that A. pra- 
lensis Lec. is the same with A. glabricollis of Europe. I have 
not compared specimens, but think that the finer punctua- 
tion of pratensis entitles it to distinct recognition, and that 
Mr. Fauvel’s remark will apply better to some of the black- 
legged varieties of what we consider A. pronus. 
35. Quedius ferox, n. sp.—Elongate, linear, black, very shining, 
antenne and legs blackish or piceous. Head oval, strongly narrowed be- 
hind, and constricted at the neck, which is not slender; sides before and 
behind the eyes sparsely punctured ; a series of five setigerous punctures 
each side above the eyes; nearer the middle, opposite the 5th one is a 
6th. Eyes not prominent, occupying the middle third of the length of the 
head. Prothorax longer than wide, not narrowed in front, sides straight, 
parallel nearly to the apex, where they are m dderately rounded, slightly 
sinuate near the base ; apex emarginate, base rounded ; there are 3 punc- 
tures each side on the apical margin, one near the margin, and one on the 
disc, about one-third the length ; there is also a large, lateral puncture near 
the margin, in front of the middle ; three small marginal ones behind the 
middle, and a few on the basal margin. Elytra smooth, with, obsolete su- 
tural stria, and 3 small sub-sutural punctures و‎ there is also a dorsal series 
of 4 very small punctures. Dorsal segments slightly iridescent, rather 
densely punctured and pubescent, with long, lateral and apical sete. 
Beneath blackish-piceous, strongly punctured, slightly iridescent. Length

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 
longas 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.

are dilated in both sexes; the last ventral segment 1s longer,

37. [5]. Cryptebium floridanum, n. sp.—Shining, hairy, with 
erect pubescence, black, becoming brown towards the tip of the abdomen, 
antenns brown, legs paler. Head as long as the prothorax, and widerthan 
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.

in form and sculpture to C. badium, but the color is different, 
and the 8d apparent ventral segment (+) has a transverse 
fold similar to that of the 9d. In C. carolinum the second 
ventral segment has (2) a transverse fold, with a row of stifl
