1878.) Le [LeConte. 
Prothorax quadrate, scarcely longer than wide, broadly rounded at apex, 
anterior one-fourth covered with obtuse granules, not arranged in concen- 
tric lines, gradually changing behind into fine, rugose, sparse punctua- 
tion. Elytra finely punctured, punctures arranged in approximate rows, 
which in places are indistinct ; apical declivity flattened, feebly concave each 
side of the sutural stria, which is not very distinct ; there are also traces at 
the apex of two other striee. Front and middle tibise not toothed ; hind 
tibiæ with a marginal row of 7 or 8 small acute spines, and a fringe of stiff 
long hairs. Length 2 mm.; .08 inch. | 
Enterprise; June, one specimen. This species may be 
placed after P. digestus Lec. (vide Rhynch. 352), but the flat- 
tened declivity of the elytra, only slightly concave near 
the suture, easily distinguishes it from all thus far described 
in our fauna. The punctures of the hinder part of the elytra 
are less fine than towards the base. The eyes are emargi- 
nate; the club of the antenne is nearly circular, and trans- 
versely annulated. 
146.. Pityophthorus seriatus, n. sp. — Elongate, cylindrical, 
brown, shining, nearly glabrous, with only a few scattered, erect hairs on 
the head, front of prothorax, and hind part of elytra Antenne and legs 
testaceous. Head flat, opaque, indistinctly punctulate, front feebly im- 
pressed, and indistinctly carinate. Prothorax quadrate, not longer than 
wide, rounded in front, anterior half with irregular, transverse, subconcen- 
tric rows of granules; sides and base sparsely but distinctly punctured. 
Elytra with striz composed of small punctures, interspaces wider than the 
strie, the alternate ones each with 4 or 5 distinct punctures of equal size 
with those of the strive; declivity not flattened nor retuse, sutural stria 
slightly impressed. Length 1.5 mm.; .06 inch. 
Tampa; April, one specimen. This species is quite dis- 
tinct by the sculpture of the elytra, and may be placed be- 
fore P. comatus, in the arrangement already cited. The 
front and middle tibie are not serrate, and the hind tibise 
have only 3 or 4 very indistinct traces of teeth, and no range 
of spines, or fringe of stiff hairs as in P. obliquus. This 
species has a deceptive resemblance to Xyleborus pubescens, 
but the generic characters of the antennal club are quite 
different, and the specific characters abundantly distinct. 
147. Cryphalus miles, n. sp.—Very small, slender cylindrical, 
blackish, shining, clothed with short stout erect bristles. Prothorax a lit- 
tle longer than wide, apex produced into an acute spine; disc with a few 
acute reclinate granules in front, sparsely punctured behind. Elytra
