PHLOEOSINUS ARIZONICUS, new species 
PLATE 38, Ficures 4, 4a 
Male.—Black, with elytra reddish brown; 1.8 to 2.37 mm. long, 
holotype 2.17 mm. long, about 1.95 times as long as wide; closely 
related to P. setosus Bruck but slightly more slender and with the 
elytral striae wider. 
Frons broad between eyes, frontal rectangle about 0.72 as long as 
wide; epistomal lobe very short; central portion widely, shallowly 
concave; with a fine, elevated, median carina (smaller than in 
setosus) extending upward to beyond center of concavity; surface 
shining, finely and closely granulate-punctate throughout, the gran- 
ules finer in concavity but present everywhere except on carina; 
pubescence inconspicuous, fine, and short. Eye more than three 
times as long as wide, more than half divided by a broad emargina- 
tion. Antenna with club about 1.8 times as long as wide, first two 
sutures slightly oblique, third suture strongly oblique. 
Pronotum about 1.24 times as wide as long; sides strongly and 
nearly regularly arcuate on posterior three-fourths, then strongly 
constricted, very broadly rounded in front; surface shining, rather 
broadly impressed just behind anterior margin, deeply, closely, rather 
finely punctured on disk, somewhat roughened, subgranulate at 
sides; median line not elevated, but surface feebly, indefinitely im- 
pressed at each side of disk in posterior third; vestiture very short 
and fine, much less conspicuous than in setosus. 
Elytra slightly wider than pronotum, about 1.26 times as long 
as wide; sides straight and subparallel on anterior half, then at 
first gently then abruptly narrowed, moderately rounded behind; 
surface brightly shining, reddish brown; striae nearly as wide as 
interspaces, rather deep, punctures moderately large, shallow, moder- 
ately spaced; interspaces narrower than in sé¢osus, convex, rugose, as- 
perate, finely punctured, asperities confused near base, somewhat irreg- 
ular throughout on disk, with fine, short setae (less conspicuous than in 
setosus) becoming stouter posteriorly. Declivity (pl. 38, figs. 4, 4a) 
with first and third interspaces strongly convex, sparsely and finely 
asperate (finer than in setosus), densely, finely punctured, with a few 
erect setae and with more numerous, flattened, scalelike, nearly white
