area from basal tliird to apical fifth ; vestiture very dense but scarcely at all 

 condensed in spots, consisting of very short robust and decumbent hairs, be- 

 coming squamulose in a small spot at each side of the pronotal disk. Head 

 very densely punctate, with a small frontal fovea ; beak stout, very feebly 

 arcuate, as long as the head and prothorax, deeply punctato-sulcate; antennae 

 moderate, inserted at apical third, the basal joint of the funicle fully as long 

 as the next three. Prothorax short and strongly transverse, three-fourths 

 wider than long ; sides parallel and almost straight in middle third, conver- 

 gent toward base and rather abruptly, strongly so and straight in apical 

 fourth ; apex truncate, about three-fifths as wide as the base ; punctures 

 rather small, very dense, witbout impunctate line, a narrow median line 

 infuscate. Elytra large and broad, barely two-thirds longer than wide, fully 

 one-third wider than the prothorax and four times as long, subparallel, 

 gradually ogival behind in apical two-fifths ; sutural notch very feeble, cuspi- 

 forin ; strial punctures moderate ; intervals from two to nearly three times as 

 wide as the striae, finely, very densely and subrugosely punctate. Legs rather 

 short ; femoral teeth small, the anterior acute. Length 4.3 mm. ; width 

 1.9 mm.

Represented by a single specimen deprived of abdomen, but pro- 

 bably a male. It is allied to rufus, although very much larger and 

 relatively wider, with denser punctuation and shorter much less 

 conspicuous vestiture. In fusciceps the subapical constriction of 

 the prothorax is totally obsolete ; it is broad and almost obsolete in 

 rvtfas and deep and abrupt in marginatus. 



22 D. brevicollis Lee— Proc. Am. Phil. Soc, XV, p. 165. 



Oblong", rather convex, not very stout, shining, blackish-piceous, 

 the beak, legs and antennae rufescent ; vestiture consisting of short 

 robust and prostrate hair, whitish in color and more or less con- 

 densed in indefinite spots on the elytra, rather dense and conspicu- 

 ous. Head very deeply, densely punctate, with a deep frontal fovea; 

 beak rather longer than the head and prothorax, deeply punctate, 

 finely sulcate, feebly arcuate, moderately stout ; antennae somewhat 

 slender, the basal joint of the funicle rather long, fully as long as 

 the next three. Prothorax one-half wider than long, subparallel 

 and strongly arcuate at the sides, strongly convergent and just visi- 

 bly sinuate toward apex, the latter rather narrow, not more than 

 two-thirds as wide as the base ; punctures coarse, deep and dense, 

 with a small elongate impunctate spot at the middle. Elytra at 

 base one-third wider than the prothorax, very nearly four times as 

 long, straight and parallel at the sides, rounded in apical third;
