granules on sixth and eighth; declivity scantily clothed with small, 
slender hairs and a few small scales, usually abraded. 
Type locality —Guerneville, Sonoma County, Calif. 
Host.—Sequoia sempervirens (Lambert) Endlicher. 
Type material—Holotype, allotype, and 7 paratypes, U.S.N.M. 
No. 55408. 
Remarks.—This species has never previously been adequately 
described, but Hopkins’ very brief characterization was accompanied 
by biological data and by a figure which make it possible to recog- 
nize it. Hopkins’ description was based on a study of a series of 
eight specimens taken by him from the bark of recently felled red- 
wood trees, near Guerneville, Sonoma County, Calif. The collection 
in the National Museum also contains lots taken from redwood at 
Duncan’s Mills, Woodside, Muir Woods, Fieldbrook, Eureka, Los 
Gatos, and Gasquet, all in California; in Cupressus, San Mateo 
County, Calif.; and in redwood, Brookings, Oreg. 
PHLOEOSINUS SQUAMOSUS, new species 
PLATE 40, Fiagures 20, 20a, 21 
Male—Black with elytra reddish brown to piceous; 3.4 to 4.1 mm. 
long, holotype 3.50 mm. long, about 2.09 times as long as wide; closely 
allied to sequotae Hopkins. 
Frons wide between eyes, frontal rectangle about 0.69 as long as 
wide, epistomal process nearly lacking; surface piceous, brightly 
shining, densely rugose-granulate-punctate below and at sides, with 
little tendency toward formation of aciculations, more coarsely, deep- 
ly, and roughly punctured above, weakly granulate; very widely, 
rather deeply concave between eyes, with a poorly developed median 
carina on lower half, often not reaching the epistomal margin, me- 
dian line above concavity slightly elevated and devoid of punc- 
tures; hairs fine, moderately short, inconspicuous. Eye about 3.5 
times as long as wide, more than half divided by a wide U-shaped 
emargination. Antenna with club slightly more than twice as long 
as wide, sutures all strongly oblique. 
Pronotum about 1.15 times as wide as long, widest at posterior 
angles; sides nearly straight and slightly convergent on posterior 
halt, then rather abruptly, arcuately narrowed to the constriction just 
behind the moderately broadly rounded anterior margin; surface 
biack, moderately shining, with very deep, moderately coarse punc- 
tures, very closely spaced, with the interstices somewhat roughened, 
subgranulate (coarser, closer, and rougher than in seguozae) ; piceous 
brown near anterior margin with very fine, very dense punctures; 
sides weakly granulate; lateral calli rather small, median line feebly
