LeConte.] 622 [April 18, 
the claws simple and divergent. The antennz and legs are 
yellow ; sometimes the elytra are rufous, with the suture 
blackish. 
65. Zygobaris subcalwa. Of the same size and form as Z. con- 
spersa, sub-rhomboidal, black, rather shining, thinly clothed with short 
pubescence, and without scales. Beak as long as the head and prothorax, 
curved, slightly thickened at the base, punctulate ; head finely punctate. 
Prothorax not wider than long, gradually narrowed in front, sides nearly 
straight, constricted near the tip; surface densely, not coarsely punctured, 
base bisinuate. Elytra wider behind the base, humeri oblique, strive deep, 
interspaces rather wide, flat, each with a row of small punctures. Beneath 
densely punctured, finely, sparsely pubescent; claws small, approximate, 
but scarcely connate at base. Length 2 mm.; .08 inch. 
Detroit; one specimen found; I have two others from 
. Pennsylvania. Differs from Z. conspersa chiefly by the finer 
punctuation, and the absence of scales. 
66. Pityophthorus anmectens. Elongate-cylindrical, brown, 
shining, with a very few slender erect scarcely serrate yellow hairs. Pro- 
thorax longer than wide, in front roughened almost concentrically for about 
one-third the length, sides and base finely sparsely punctured, punctures 
becoming larger, as they approach the roughened surface. Elytra with ap- 
proximate rows of small punctures, interspaces transversely rugose; api- 
cal declivity retuse, deeply impressed near the suture, which is elevated ; 
sutural tip rather acute. Front tibiz with two small teeth. Length 16 mm. ; 
.06 inch. 
3’. Head broadly concave, opaque with shallow punctures, concavity 
fringed with long yellow hairs. : 
®. Head slightly convex, strongly and deeply punctured. 
Tampa, Florida, on yellow pine; Mr. E. A. Schwarz. This 
species is of slender form, and is most nearly allied to P. ni- 
tidulus, but is smaller, and has the prothorax more finely 
punctured. The color is also different, the Californian and 
Alaskan nitidulus being black, while this is always brown. 
67. Pityophthorus consimilis. Yellow brown, shining, with 
a few erect yellow hairs, of the same form and sculpture as P. annectens, 
‘except that the obtuse elevation of the apical declivity of the elytra, and 
the corresponding part of the suture are sparsely crenate. The antenne 
and legs are yellow, and the form is perhaps a trifle more robust. Length 
1.6 mm.; .06 inch. 
o'. Head flat, slightly pubescent, with a large, sub-quadrate, densely 
punctured opaque spot occuping nearly the whole upper surface, and di- 
vided by a longitudinal impressed line ; sides shining, sparsely punctured. 
©. Head slightly convex, strongly punctured.
