evenly punctured, punctures separated by at least their own diameter, 
longitudinal and transverse depressions absent. Elytra wider at base than 
thorax and slightly narrower than widest part of thorax, humeral angles 
rounded, sides almost straight and slightly divergent to posterior three 
fourths where elytra is broadest, thence broadly rounded to apex, striz 
well defined but not deep, distinctly though shallowly punctured, intervals 
but slightly convex, with even ones broader than odd, a row of fine punc- 
tures down middle of each. Beneath sparsely punctured. Posterior fe- 
mora stout, oval, the marginal line absent; the middle and posterior tibia 
moderately stout with two oblique ridges externally, the spurs of middle 
tibia long, about equal to first two tibial joints, and unequal, those of 
posterior stouter and subequal; the tarsi about two thirds the length of 
tibia, the first joint longer than two following and slightly broader at apex, 
the tarsal claws about two thirds length of last tarsal joint. Length 4 
mm., breadth 2 mm. 
Type and paratype in my own collection, collected by my friend, Mr. 
J. C. Bridwell, in the Imperial Valley, Cal., in February, 1911. 
This species, according to Dr. Horn’s table,* would come im- 
mediately after P. caelatus Lec., and before P. hydropicus Horn, 
being of the robust type and having the oblique ridges on the 
posterior tibia as in the former species and the thorax without 
transverse grooves as in the latter. It is even closer to the re- 
cently described P. ambiguus} Fall, as regards its general color, 
thoracic and tarsal characters, but is amply distinct, as was proven 
by Mr. Fall, who very kindly compared it with his type. Its main 
difference from this last is in regard. to the type of sculpturing 
on the head. 
Dichelonycha oregona n. sp.—Size and form of fulgida and crotchu; 
black except elytra, antennz, forelegs, middle and hind thighs which are 
testaceous; upper surface sparsely clothed with short, fine, brown hair, the 
lower with a rather dense covering of coarse white pile. Head including 
eyes distinctly more than half as wide as thorax, densely, coarsely, and 
more or less regularly punctate, clypeal suture impressed, strongly angu- 
late; clypeus moderately reflexed, truncate in front, with lateral angles 
broadly rounded and sides a little convergent anteriorly; antenne nine- 
jointed, with club subequal in length to funicle, terminal joint of maxil- 
lary palpi widened apically and broadly obliquely truncate. Thorax with- 
out median groove, surface moderately.coarsely and closely punctate later- 
ally, more finely and sparsely on disc, basal and apical marginal lines dis-
