REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 419 
as wide, more than half divided by a deep, rather wide emargination. 
Antenna with club more than twice as long as wide, first and second 
sutures partially septate, slightly oblique, third suture strongly 
oblique. 
Pronotum about 1.22 times as wide as long, sides feebly arcuate 
on posterior two-fifths, then strongly, arcuately narrowed, strongly 
constricted just behind the very broadly rounded anterior margin; 
surface rather weakly shining, transversely impressed just behind 
anterior margin; disk with close, deep punctures of moderate size, 
shghtly roughened and subgranulate at sides; median line weakly 
elevated behind but punctured throughout; vestiture short and fine, 
less conspicuous than in hopping?, more so than in antennatus. 
Elytra slightly wider than pronotum, about 1.25 times as long as 
wide, widest at base; sides nearly straight and subdparallel on anterior 
two-thirds, very broadly rounded behind; surface shining; striae 
deep, rather narrow on disk, wider on sides, punctures small, rather 
close; interspaces several times as wide as striae, convex, finely and 
closely granulate, each with a slightly irregular, uniseriate row of 
coarser granules or asperities; pubescence consisting of short, fine, 
moderately abundant, reddish-yellow hairs. Declivity with strial 
punctures somewhat coarser and rougher; first and third interspaces 
rather weakly convex, with a few irregularly arranged, rather sharp 
serrations; second interspace flat, narrowed toward apex, finely, 
sparsely punctate; vestiture short and fine, reddish yellow, more 
conspicuous than on disk, entirely hairlike. 
Female.—Similar to male in general habitus; frontal rectangle 
about 0.64 as long as wide; frons wider between eyes than in male, 
somewhat flattened, impressed between the eyes, finely granulate- 
punctate, with a fine, elevated median carina on lower half; sides of 
pronotum not so strongly constricted near anterior margin; elytral 
declivity with smaller, sharp, irregularly arranged serrations. 
Type locality —F airfax, Cypress Ridge, Marin County, Calif. 
Host.—Not recorded. 
Location of type-—Canadian National Collection, Ottawa, Canada. 
Remarks.—I have studied one specimen from the type locality; 
two from Mount Saint Helena, Calif., taken from Cupressus sar- 
gentii Jepson by Donald DeLeon; and three specimens from Mount 
Tamalpais, Calif., taken from (. sargentit by F. P. Keen. 
The species was originally described by Swaine under the name of 
Phloeosinus minutus. Bruck, finding this name preoccupied, renamed 
it swainet in honor of the original describer.
