except membrane, minutely and sparsely punctate, each puncture bear- 

 ing a very fine, short inclined hair. Length, 3.5 — 3.7 mm. (Fig. 160). 



Marion, Vigo and Posey counties, Ind., Jan. 12 — Sept. 24, 

 scarce ; taken in winter beneath the bark of dead willow trees, 

 in spring while sifting dead leaves from about the bases of 

 stumps, and in autumn from foliage of cottonwood. Willow 

 Springs, 111., Feb. 22 (Gerhard) . As noted above, I consider the 

 A. boreal is Dallas (1852, 588), described from Hudson's Bay, a 

 synonym of Say's species. The few structural characters which 

 he mentions all agree with those given by Say. Combining 

 the published records of the two forms, the known range of 

 the species extends from Hudson's Bay and New England west 

 to Colorado, with many gaps intervening. It is evidently a 

 palsearctic American species, the Indiana stations being the 

 most southern known. Van Duzee (1894, 180) mentions it as 

 found near Buffalo, N. Y. : "Occasionally on the trunks of black 

 willow trees and about osier bushes ; sometimes very active in 

 the bright July sunshine about these trees. Also taken in Feb- 

 ruary hibernating." In Colorado it was found in August above 

 timber line on Clematis and other plants on the steep side of 

 the mountains. 



III. Tetraphleps Fieber, 1860, 262. 



Medium sized oblong or oval pubescent species having the 

 eyes slightly distant from pronotum ; beak reaching onto 

 mesosternum, joint 1 not reaching eyes, 2 more than twice the 

 length of 3 ; joint 2 of antennae clavate, 4 fusiform ; pronotum 

 with sides flattened and in front curved inward, reaching for- 

 ward beyond the base of pronotal collar; hind margin widely 

 and shallowly concave ; elytra densely and finely punctate, the 

 cuneus very long, membrane with four distinct veins ; apex of 

 abdomen with long exserted hairs ; hind coxae approximate ; 

 osteolar channel nearly straight, prominently elevated toward 

 apex. Four of the seven known species occur on coniferous 

 trees in the eastern states. 71 



KEY TO EASTERN' SPECIES OP TETRAPHLEPS. 



a. General color dark brown or piceous; joint 2 of antennae equal in 

 length to width of head across eyes. 

 b. Beak not reaching middle coxa?; elytra pale brown, the apex of 

 clavus, corium and embolium darker. 611. Americana. 



71 The T. canadensis Prov., known only by the single type, is not included in 

 the key, as the distinctive characters given in the original description are insufficient.
