equal to the next three in hoth sexes. Prothorax small, transverse, about two- 

 thirds wider than long, nearly similar in the sexes, abruptly, strongly rounded 

 and very strongly narrowed near the apex, the latter broadly and rather 

 strongly tubulate, four-fifths as wide as the base, broadly, feebly arcuate, 

 feebly sinuate in the middle ; punctures uot very coarse but deep, dense 

 although distinctly separated, the impunctate line completely obsolete. Elytra 

 at base from one-third to one-fourth wider than the prothorax, four times as 

 long as the latter, parallel in the male but gradually distinctly wider behind 

 in the female, obtusely ogival at apex ; strial punctures moderately large, 

 very deep, perforate, close-set ; intervals nearly fiat, minutely, feebly, rather 

 sparsely punctate. Abdomen finely, evenly, not densely punctate. Length 

 4.5-5.5 mm. ; width 2.0-2.2 mm. 



Indiana. 



Allied to laticollis, but distinguishable by the pale coloration and 

 especially by the shorter, more robust beak of the male and the 

 slightly larger eyes of the same sex ; the beak and head are also 

 much more coarsely and densely punctate and setose. The tooth 

 of the anterior femur is larger in the present species than in lati- 

 collis, and the elytra are parallel in the male and not gradually 

 feebly inflated behind. 



7 D. liystricilla n. sp. — Oblong-oval, convex, feebly shining, piceous- 

 black and more or less rufescent toward the sides, to pale rufo-testaceous 

 throughout ; legs always pale ; vestiture dense, consisting of short stout 

 pointed and decumbent hairs, cinereous in color and but feebly mottled, the 

 pronotum with two narrow indefinitely nubilate darker vittae, the elytra 

 bristling also with long erect stiff setae, not close-set in a single line on each 

 interval. Head and beak very densely punctate throughout, the latter not 

 longitudinally carinulate or sulcate, in the male short, about as long as the 

 prothorax, with the antennae inserted at apical third, in the female just visi- 

 bly longer, but not longer than the prothorax, with the antennae inserted at 

 apical two-fifths, in both sexes feebly, evenly arcuate and stout ; antennae 

 stout, the basal joint of the" funicle as long as the next three, second much 

 shorter than the next two, outer joints gradually thicker and transversely 

 oval, club thick, oval, pointed. Prothorax one-half wider than long, parallel 

 and broadly arcuate at the sides, moderately constricted and broadly sub- 

 tubulate at apex, the punctures not coarse but deep and dense ; impunctate 

 line obsolete. Elytra at base one-third wider than the prothorax, about three 

 and one-half times as long as the latter, the sides parallel and nearly straight ; 

 apical third evenly ogival ; sutural notch broad and rather large ; striae un- 

 impressed, the punctures moderately coarse, deep, somewhat close-set ; inter- 

 vals minutely, very feebly and somewhat closely punctate. Abdomen closely, 

 rather coarsely, confusedly and subrugosely punctured. Length 2.7-3.3 mm. ; 

 width 1.1-1.5 mm.
