GEO. H. HORN, M. D. 
littorali!4 Escb. — Form robust, convex, brownish piceous or darker fer- 
ruginous, scarcely sbining. sides of tborax (more broadly beneath) and elytra, 
antenme and legs yellowish testaceous; antennae rather stout, joints 6-10 as 
broad as long, eleventh oval ; bead sparsely, rather coarsely punctate ; thorax 
broader at middle than long, sides arcuate, sinuate in front of the hind angles, 
which are acute and feebly divergent, the carina short, hut well marked ; disc 
sparsely punctate, basal margin without trace of incisure: elytra oval, humeri 
obliquely rounded, disc rather deeply striate, strise, not punctate, intervals con- 
vex, sparsely punctate near the base, gradually becoming granulate toward the 
apex ; body beneath piceous, except the flanks of the prothorax, these finely 
punctate externally, more coarsely near the inargin ; under surface punctate, 
hut not closely, except on the last ventral segment, which is quite rugose. 
Length 8 — 11.5 mm. ; .32 — .46 ineh. 
In well preserved specimens the surface above and beneath is 
sparsely fulvo-pubescent. A variety entirely yellowish is mentioned 
by Mannerheim and Candeze, not the result of immaturity, as might 
be suspected, but truly varietal, as has been observed in many species 
living along the sea-coast. 
Seems to be abundant on the Alaskan sea-coast. 
Group HYPERBOREUS. 
Prosternal sutures straight, very slightly convergent posteriorly. 
Legs slender, tibial spurs small. Maxillary palpi not prominent, 
the last joint triangular, as in the squalidus group. Thorax smooth, 
sparsely punctate, median line more or less impressed, the basal in- 
cisures distinct, hind angles long, slender and divergent. Surface 
nearly, or quite glabrous, body winged. 
This group contains but three species, as far as known to me, espe- 
cially notable by their oblong, feebly convex form, nearly glabrous 
surface, subsulcate thorax with slender hind angles. 
The species are separated as follows : 
AntenuiB entirely ferruginous. 
Anteimse rather slender, the joints longer than wide g;raii(licollis. 
Antenna stouter, joints triangular, as wide as long liyperboretis. 
Antenna piceous, except at base, the joints longer than wide. 
Elytral intervals fiat Saiiboriii. 
Elytral intervals convex barbatiis. 
These inhabit the more northern or elevated regions of our country, 
one of them {hyperhorens) having a circum-polar distribution in both 
hemispheres. 
C’. graiKlicollis Lee. — Oblong, moderately convex, piceous shining, with 
faint metallic lustre, elytra paler than the thorax; surface scarcely pul)escent ; 
antcTina ferruginous, joints all longer than wide; front fiat, coarsely not closely
