CLASSIFICATION OF THE SUBFAMILY CRYPHALINZ. 39 
Genus PIPERIUS, new genus. 
Antennal funicle 4-jointed, joints 3 and 4 of equal width and 
narrower than 2; club oblong, elliptical, base oblique, sides faintly 
sinuate, apex rounded, with four straight sutures on anterior face 
and three broadly procurved sutures on posterior face, the first dis- 
continuous, without septa; eyes short, elliptical, emarginate. Type 
of genus, Piperius pini, new species. 
Piperius pini, new species. 
(Pl. I, fig. 18.) 
Length, female type, 1.15 mm.; body oblong, elliptical, light brown; pronotum 
with fine, short, erect pubescence, anterior margin with four minute teeth, rugosities 
fine, sparse, approximately concentric, the space acuminate into posterior dorsal area, 
not extending to lateral area, posterior dorsal and lateral areas opaque, alutaceous; 
front convex, shining, faintly rugose; elytra shining, clothed with very fine, short 
scales and sparsely placed longer ones in approximate rows, longer on the declivity, 
striz faintly evident on the dorsal area, declivity convex, without striz, apex obtusely 
rounded. Nosexual differences observed. Baguio, P. I.,in Pinus insularis, October 
4, 1911; C. V. Piper, collector. Type, Cat. No. 7603, U. 8. National Museum. 
Genus CRYPHALUS Erichson. 
Antennal funicle 4-jointed, joint 4 broader; club compressed, 
broad, with sides equally rounded, sinuate, apex broadly rounded, 
with three slightly recurved sutures on anterior face and three 
broadly procurved sutures on posterior face; eyes short, oval, 
narrowly but distinctly emarginate. The male is slightly smaller 
than the female and its front is narrower. 
Notre.—The group of genera to which this genus belongs is charac- 
terized by the obscure to absent striz of the elytra and the presence 
of basal and lateral margins on the pronotum; the genera immedi- 
ately allied to it are characterized by the broad emarginate third 
joint of the anterior tarsus and by the emarginate eyes. Cryphalus, 
as here designated and restricted, stands out distinct from the other 
genere of the subfamily, and there seems to be no excuse whatever for 
including so many of the genera under this name, as has been done in 
Hagedorn’s Catalogue. 
I. Elytra with fine, densely placed scales and sparse, erect, interspacial hairs.
