REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 443 
Hopkins at the time the description was prepared and one of these 
is marked “type,” although it had apparently never been entered in 
the type book or assigned a type number. Others of the same lot 
I have designated paratypes. 
Type locality —Golden Gate Park, Calif. 
Additional locality —Berkeley, Calif. 
Host.—Cupressus macrocarpa Gordon. 
Type material—Holotype and nine paratypes, U.S.N.M. No. 55406. 
Remarks.—In addition to the type series the writer has studied 
about 90 specimens from Alameda County, Berkeley, Palo Alto, Los 
Gatos, Monterey, Watsonville, and Salinas, Calif. All but 1 lot are 
from Cupressus macrocarpa Gordon. One single lot was taken from 
Sequoia sempervirens (Lambert) Endl., in Alameda County.

Male.—Piceous black, with elytra reddish brown to piceous brown; 
2.8-4.0 mm. long, about 1.99 times as long as wide. 
Frons very wide between eyes, frontal rectangle about 0.65 as long 
as wide, epistomal lobe short; surface piceous, densely, moderately 
coarsely granulate-punctate, rather: deeply, not widely concave be- 
tween eyes, with median carina extending from above center of con- 
cavity to epistomal margin, elevated and moderately acute, continued 
as low, interrupted elevation on upper part of frons, shining and 
impunctate above; hairs short, fine, and very inconspicuous. Eye 
about 3.5 times as long as wide, about two-thirds divided by a deep 
U-shaped emargination. Antenna with club less than twice as long as 
wide, all sutures oblique. 
Pronotum about 1.08 times as wide as long, widest at posterior 
angles; sides regularly arcuate and convergent from base to the weak 
constriction just behind the moderately broadly rounded anterior
