111 general appearance the species resembles, somewhat, Taphrocems 
agriloides. 
Hub . — New Mexico, no ])recise region known. 
A. blaiidiiK n. sp. — Rather robust, subcyliiidrical, slightly narrowed behind, 
cupreo geneons, sides of thorax with white pubescence, elytra with a vitta from 
base to near the apex. Anteniue passing slightly the middle of the thorax, 
seneons, serrate from the fifth joint; head slightly convex, a feeble median im- 
pression from the occiput to the clypens. the latter broad at base, surface rather 
coarsely punctate and obliquely strigose. Thorax a little wider than long, sides 
regularly arcuate, slightly sinuate near the hind angles, which are rectangular 
and without trace of a carina, lateral margin sinuous, disc convex, without trace 
of median sulcus, lateral oblique impression feeble, surface rather closely punc- 
tate with feeble obliijue strigse, sides pubescent, more broadly behind ; scutellum 
transversely carinate; elytra very slightly sinuate at middle and slightly broad- 
ened. apices rounded, serrulate, disc, convex, basal depression feeble, surface 
rather coarsely imbricate and with a vitta of whitish pubescence from the base 
to the apex close to the suture; body beneath cupreo-teneous ; prosternal lobe 
truncate, with a feeble emargination at middle, the inten'.oxal proc^ess narrowed 
from base to apex, the tip obtuse, propleurje punctate, with scale-like white hairs 
and effloresence ; metasternum at sides irnbricately sculptured and with the 
ejiisternum and outer half of coxSl plate clothed with white inibescence. Ab- 
domen moderately closely imbricate, more roughly at the sides of the first two 
segments, clothed along the sides with whitish pubescence, vertical portion of 
first segment with white pubescence; pygidium coarsely punctate, feebly cari- 
nate; claws broadly toothed at middle. Length .25 inch. ; 6.5 mm. 
Male . — Prostenium coarsely punctured, s[)arsely pubescent ; first 
two ventral segments roughly sculptured at middle; anterior tibia 
distinctly, middle tibia feebly mucronate, the posterior simple. 
Female . — Prosternum less closely punctate, scarcely hairy ; first 
two veutral segments simply punctate ; tibite all simple. 
Variaiiom . — The three specimens before me seem to have been 
collected with care and have a rather dense efflorescence between the 
hairs, so that they seem very conspicuous. It is |)robable that speci- 
mens collected in alcohol or wet in any way, lose the efflorescence, 
and the pubescent spots will appear le.ss distinct. There is no varia- 
tion in the specimens examined. 
Hab. — Tehachepi, Cal. Collected by H. F. Wickham. 
.4. ab, jectiis n. sp. — Subcyliiidrical, slightly narrower behind, dull cupreous, 
each elytron with three faint pubescent sjiots. Antennse .scarcely passing the 
middle of the thorax, serrate from the fifth joint; head convex, with a broad 
depression from occiput to clypens. surface rather coarsely punctate and obliquely 
strigose. Thorax fully as long as wide, widest one-third from apex, slightly 
narrowed to base, sides feebly arcuate in front, slightly sinuate posteriorly, hind 
angles rectangular without trace of carina, margin sinuate, disc convex, with a
