Cc. suttulatus Lec. New Species, 1863, p. 65. 
Oblong-oval, blackish, opaque, moderately convex. Head granulate, 
sparsely pubescent. Thorax twice as wide as long, apex deeply emar- 
ginate, angles prominent in front, sides broadly arcuate, margin explanate 
and serrulate, hind angles obtuse, base broadly arcuate at middle on each 
side, feebly sinuate, surface coarsely granulate, sparsely pubescent. Elytra 
with rather irregular rows of moderately coarse granules, surface sparsely 
pubescent, each elytron with spots of more dense pubescence forming a sinu- 
ous band near the middle and another behind it. Body beneath granulate, 
opaque. Length .18 inch; 4.5 mm. 
This species occurs rather abundantly in the Middle 
States. 
The margin of thorax is equally explanate at apex and 
base. The third joint of the antenne is very nearly as long 
as the two following together. The abdomen is rather 
roughly granulato-punctate. 
C. pacificus, n. sp. 
Resembles the preceding in form and color but is rela- 
tively more elongate and differs besides as follows: 
Thorax shorter, more transverse, margin widely explanate in front, be- 
coming gradually less so posteriorly so that the thorax appears to become 
narrow behind. Abdomen coarsely but not densely punctured, Antenne 
with third joint scarcely longer than the fourth, the latter not longer than 
the fifth. Length .18 inch; 4.5 mm. 
Occurs not uncommonly at Vancouver. 
LASCONOTUS Erichs. 
Antenne eleven-jointed, terminated by a three-jointed club, without 
antennal groove, first two joints stout, the first a little longer than the 
second, third slightly longer than the fourth, three to eight sub-equal, ob 
conical, last three forming an abrupt club. Head broader than long. 
Clypeus feebly emarginate in front, at sides broadiy arcuate and extending 
posteriorly, forming a well-defined supraorbital ridge, in one species par- 
tially concealing the eyes from above. Eyes round, rather finely granu- 
lated, moderately prominent. Thorax quadrate, quadricostate. Scutel- 
lum small. Elytra parallel, costate. Abdominal segments gradually 
shorter, fifth slightly longer than the fourth, intercoxal process narrow, 
acute. Posterior coxe transverse. Tibize slightly wider toward the tips, 
the anterior with two spinules at the outer angle, all with small terminal 
spurs. Tarsi as in Ditoma. 
This genus was founded by Erichson on an undescribed 
species, and but few words of diagnosis given. Its charac-
