and unusually coarse and deep; legs moderately long, not very stout. 
Male with ventrals two to four feebly impressed along the middle, the 
impression of the fifth subobsolete; sixth broadly arcuato-truncate at 
tip, with a very small deep and acutely angulate notch, deeper than 
wide and not more than a tenth or twelfth as wide as the apex, par- 
tially concealed by the pubescence as usual; disk not distinctly modi- 
fied. Length 6.8 mm.; width 1.25 mm. Montana (Kalispell), —

6 — Antennae of the male very slender, rather longer than the head and pro- 
thorax, with the medial joints rather more than twice as long as wide, 
shorter and relatively thicker in the female, with the medial joints 
distinctly less than twice as long as wide. Body rather stout, the head 
semicircularly rounded, the eyes wzll developed, the surface more finely 
and closely punctured than in captiosus, a little narrower in the female 
than in the male and with the sides feebly converging behind the eyes; 
prothorax oblong, broad, only slightly longer than wide, much wider 
than the head, the median impunctate line narrow; elytra in the male 
quadrate, a third wider and a fifth longer than the prothorax; in the 
female slightly longer than wide, two-fifths wider and more than a fourth 
longer than the prothorax; punctures close-set and only moderately 
coarse, similar in size to those of the pronotum. Male with ventrals two 
to five subequally and feebly impressed along the middle, the sixth witha 
small deep and acutely angular notch as in the preceding species; female 
with the sixth ventral greatly produced in an obtusely rounded lobe, un- 
impressed, the body smaller and less stout than in the male. Length 
6.0-7.0 mm.; width 1.2-1.26 mm. Massachusetts, Canada, New York,

Antennae of the male thicker, longer than the head and prothorax but 
with the medial joints somewhat less than twice as long as wide; in the 
female still thicker, barely as long as the head and prothorax, with the 
medial joiats about one-half longer than wide. . Body resembling pwnc- 
tulatus throughout in color and sculpture, but a little stouter, with 
slightly smaller eyes, and with the male and female similar in form and 
very nearly so in size, the head in the female being somewhat narrower 
but not noticeably narrowed behind the eyes. Male with the second 
and third ventrals unimpressed, the fourth and fifth rather broadly and 
very feebly impressed along the middle, the sixth with a very small 
triangular notch, deeper than wide, nearly as in the preceding species 
but a little less deep and rather broader at the opening, the surface 
with the pubescence denser in the region of the notch asusual. Length
