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), — Mr.

Prothorax strongly and more coarsely punctate, the punctures more or less 

 close -set 6 



6 — Antennae of the male very slender, rather longer than the head and pro- 

 fiorax, 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 Well developed, the surface more finely 

 and closely punctured than in captiosus, a little narrower in the female 

 than in the male and with the siles 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 aud more than a fourth 

 longer than the prothorax; punctures close-set and only moderately 

 coarse, similar in size to those of the pronotura. Male with ventrals two 

 to five .subequally and feebly impressed along the middle, the sixth with a 

 small deep and acutely angular no^ch as in the preceding species ; female 

 with the sixth ventral greatly produced in an obtusely rounded lobe, un- 

 impressed, the body smaller and lei>s 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 joints about one-half longer than wide. Body resembling prmc- 

 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 as usual. Length 

 7.0 mm.; width 1.3 mm. Idaho (Priest River), — Mr. Wickham.
