CLASSIFICATION OF THE SUBFAMILY CRYPHALINA, 51 
declivity steep, shining, fiat, interspace 1 broad, slightly elevated, 2 broad, flat, 
slightly impressed, 3 narrow, faintly elevated, all with a row of granules, strial punc- 
tures coarse, faintly impressed, pubescence sparse and longer on declivity. Grant 
County, Va., in Betula sp., July 9, 1891; author, collector; Hopk. W. Va. No. 4004. 
Type, Cat. No. 7630, U. 8. National Museum. 
Male.—Deéclivity not distinctly different from that of female except that it 1s more 
shining and the granules are less evident; front broad, convex, faintly rugosely punc- 
tured, slightly impressed and shining, with faint median impression and a few long 
hairs; pronotum broader. The length varies from 2.4 mm. to 4.5 mm.; otherwise the 
characters are fairly constant. 
Dryocoetes liquidambaris, new species. 
Length, female type, 3.85 mm.; body oblong, élliptical, dark reddish; pronotum 
with moderately long pubescence on anterior dorsal area and lateral margin, pronotal 
rugosities fine and extending to base on lateral margin, posterior dorsal area distinctly 
punctured, becoming rugose toward the basal angle; front broad, flat, with moderately 
dense, golden yellow pubescence; elytra with punctures of interspaces in irregular 
rows, impressed, declivity shining, steep, flattened, interspace 1 broad, slightly 
elevated, 2 broad, flat, 3 narrow, each with a row of rather coarse granules, pubescence 
sparse, not very long even on declivity. Virginia Beach, Va., in Liquidambar styra- 
ciflua, November 26, 1907; author, collector; Hopk. U. 8. No. 6962b. Type, Cat. 
No. 7631, U. 8S. National Museum. 
Male.—Declivity more shining and almost without granules; front broad, sub- 
convex, anterior half flat, with faint carina, posterior and lateral margins with a few 
long hairs. The length ranges from 3.45 to 4.2 mm. 
Dryocoetes americanus, new species. 
Length, female type, 3.65 mm.; body oblong, elliptical, reddish brown; pronotum 
with fine regular rugosities extending to the basal angles, median and posterior dorsal 
areas with coarse punctures extending toward the basal angle, dorsal line distinct; 
front convex, subgranulate, with a few long hairs and with short anterior median 
elevated line; elytral strize faintly impressed, punctures coarse, interspaces narrow, 
with moderately coarse, irregular punctures, declivity subconvex, interspace 1 faintly 
elevated, 2 and 3 equal in width, not impressed or elevated, each with a row of fine 
granules, pubescence sparse and moderately long, stria 1 faintly impressed. Cheat 
Bridge, Randolph County, W. Va., in Picea rubens, September 1, 1890; author, col- 
lector; Hopk. W. Va. No. 86. Type, Cat. No. 7632, U. 8. National Museum. 
Male.—Front very broad, convex, anterior area flattened, shining, with a few hairs; 
declivity more shining, smoother, striz less distinctly impressed than in female, but 
each interspace with row of faint granules. 
Note: This is the eastern North American species which heretofore has been con- 
fused with D. autographus Ratz., from which it differs in a number of details. It 
varies in length from 2.95 to 4.1 mm., and there is considerable variation in the 
sculpture. Specimens from the Rocky Mountain region show some minor differences 
that are hardly distinctive enough to justify the designation of a different species; 
however, in this genus, in which all the alliea species are separated by slight differ- 
ences, it is probable that there are more species than are here recognized. 
Dryocoetes piceae, new species. 
Length, female type, 2.5 mm.; body oblong, elliptical, reddish brown; pronotum 
and elytra clothed with long, erect hairs, becoming longer toward sides and declivity; 
front densely clothed with long yellow hairs; pronotum finely granulate throughout, 
excepting a faint median line; elytral strize not impressed, punctures in approximate
