nifo-testaceons, the outer joints piceous ; head si>arsely punctate; thorax longer 
than wide, not narrowed in front, widest at middle, sides feebly arcuate, sinuate 
in front of the hind angles, which are slender, acute, distinctly divergent and 
carinate above, di,sc moderately curved, the median line vaguely impressed from 
base to apex, basal incisures distinct; surface sparsely finely punctate: elytra 
oblong oval, widest behind the middle, humeri oblique, disc striate, strise dis- 
tinctly punctured, intervals flat, sparsely punctate, but more coarsely than the 
thorax ; jn-osternal lobe moderately prominent, the border distinctly beaded, a 
transverse impression posteriorly, coarsely punctate in front, more finely and 
sparsely toward apex, punctuation at sides denser and intermixed, propleurte 
rather densely punctate and more opaque, with coarser and fine punctures inter- 
mixed ; epipleurre jiale; metasternum and abdomen rather densely punctulate 
with coarser punctures intermixed ; legs rufo-testaceous, tarsi darker. Length 
5,5 — 7 mm.; .22 — .28 inch. 
The hind angles of the thorax at tip, the epipleurae of the elytra 
and a narrow border of the under side of thorax are usually rufes- 
cent. The median line of the thorax, although feeble, is distinctly 
impressed from base to apex ; all the strite of the elytra are punctate. 
Occurs in the White Mountain region of New Hampshire, where 
it was first collected by Mr. F. G. Sanborn, and since by Blanchard, 
Henshaw and others. 
barbatiis Sahib. — Oblong, moderately convex, piceous black, moderately 
shining, sparsely clothed with short, inconspicuous, brownish pubescence; an- 
tenn® slender, feebly serrate, piceous, the two basal joints pale; head rather 
coarsely punctate, front triangularly flattened, the middle of the triangle elevated 
in an umbone; thorax longer than wide, very little narrowed in front, sides 
feebly arcuate, sinuate in front of the hind angles, which are slender and slightly 
divergent, carina well marked, but short; disc convex, a median impression 
reaching the base and very nearly the apex ; surface moderately coarsely punc- 
tate in front and at sides, smoother at middle and near base; elytra oblong-oval, 
wider slightly behind the middle, humeri rounded, disc convex, deeply striate, 
strire punctate, intervals convex, moderately closely punctate; prosternum trans- 
versely Impressed, rather finely punctate behind the groove, very coarsely in 
front, the lobe moderately prominent, subtruncate; propleurje opaque, slightly 
rugulose, coarsely sparsely punctate; epipleurte pale ; abdomen closely punctate 
with coarser punctures intermixed, especially near the sides; legs rufo-testace- 
ous, the tarsi piceous. Length 6.5 mm. ; .26 inch. 
Very close to Sanborni, and possibly only an Arctic form of it. 
The pubescence of the prosternal lobe seems to have been rather 
exaggerated in importance and extent, as all the species of the pres- 
ent and the ahbreviatus groups have a slight pilosity in that portion 
not by any means dense, and often lost by abrasion. 
I owe to Dr. Sahlberg the privilege of examining a typical speci- 
men. Occurs in the vicinity of St. Lawrence Bay extending to Port 
( 'larence on the American coast.
