Coleopterological Notices, IV. 307 



rather closely punctate. Abdomen finely, not very densely punc- 

 tate. Length 4.4 mm.; width 1.9 mm. 



The description is drawn from a male taken in Michigan. It also 

 occurs at Lake Superior and in Iowa according to LeConte. 



f) D. aniplUS n. sp. — Oblong, feebly convex, robust, strongly shining, 

 pale brownish-Havate thronghout ; vestiture very sparse, consisting of small 

 robust and recumbent hairs, feebly condensed in subtransverse wavy lines on 

 the elytra behind, also denser at the humeri ; erect setae completely wanting. 

 Head finely but deeply and rather densely punctate and setose, the frontal 

 fovea small but deep ; beak in the male slender, strongly arcuate, evenly 

 cylindrical, finely but deeply, rather closely lineato-punctate, very slightly 

 more than one-half as long as the elytra, with the antennae inserted near 

 apical two-fifths, first funicular joint as long as the next three, second equal 

 to the following two combined. Prothorax small, transverse, nearly three- 

 fourths wider than long, the sides sul)parallel and strongly, almost evenly 

 arcuate, not very abruptly rounded near the apex but distinctly constricted, 

 the apex truncate, very broadly tubulate, more than three-fourths as wide as 

 the base; punctures rather fine but deep, quite sparse, the impunctate line 

 narrow and not attaining the apex. Elytra at base nearly two-fifths wider 

 than the prothorax, about four times as long as the latter and scarcely notice- 

 ably wider behind the mi.ldle, the sides gradually ogival in apical third, with 

 the sutural notch rather large; humeri rectangular, rounded, broadly ex- 

 posed ; strial punctures rather small but very deep, perforate and close-set ; 

 intervals flat, very minutely feebly sparsely and inconspicuously punctate. 

 Abdomen finely, distinctly, subrugosely punctate. Length 5.4 mm. ; width 

 2.3 mm. 



Colorado. 



A rather large species allied to laticollis and parvicollis, but 

 differing in its entirely pale reddish-ochreous coloration, and much 

 broader form. The two specimens before me are apparently males. 



6 I>. parvicollis n. sp. — Oblong, moderately stout, feebly convex, shin- 

 ing, rufo-testaceous, irregularly mottled with piceous-black, especially toward 

 the middle ; vestiture rather sparse, consisting of short robust and recumbent 

 pale hairs, unevenly and feebly condensed and mottled, without trace of erect 

 setae. Head finely, deeply, very densely punctured and with a deep frontal 

 fovea; beak in the male somewhat stout, feebly but distinctly arcuate, coarsely 

 deeply and closely punctate in longitudinal furrows, strongly and conspicu- 

 ously setulose and slightly longer than the head and prothorax, distinctly 

 less than one-half as long as the elytra, with the antennae inserted just 

 beyond apical two-fifths ; in the female the beak is very long, slender, less 

 sulcate, strongly, evenly arcuate, fully two-thirds as long as the elytra, with 

 the antennae Inserted just beyond the middle ; ba-:al joint of the funicle sub-
