Indiana. 



The type and unique specimen is a male, the abdomen having- a 

 large rounded and deep impression near the base. It is allied to 

 ritfus but differs in its larger size, coloration, longer beak and more 

 elongate antenna! club, longer legs, more distinct femoral teeth, and 

 in the finer, shorter vestiture, more distinctly defined in white mar- 

 morate patches on the dark elytra.

 (Erirhinus). 



Oblong, feebly convex, pale flavo-testaceous throughout, the el vtra 

 feebly clouded with brownish toward the middle; integuments shin- 

 ing, not very densely clothed with robust squaniuliform hairs, con- 

 fusedly condensed in transversely wavy spots and whitish in color. 

 Head very densely punctate, the squamules along the inner margin 

 of the eye erect and bristling; beak rather stout, somewhat longer 

 than the head and prothorax in the female, and with the antennae 

 inserted beyond apical two-fifths, rather coarsely, densely lineato- 

 sulcate and punctate, very feebly arcuate ; antenna? rather slender, 

 the basal joint of the funicle not quite as long as the next three, 

 second but slightly longer than the third ; club moderate, slightly 

 darker in color, sparsely pubescent. Prothorax one-half wider than 

 long; sides subparallel and rather strongly arcuate, convergent and 

 just visibly sinuate near the apex; punctures rather coarse, very 

 deep, somewhat dense, without impunctate line. Elytra at base 

 one-third wider than the prothorax, but slightly more than three 

 times as long, parallel, obtusely rounded in not more than apical 

 third; sutural notch small but deep; strial punctures coarse deep 

 and very close-set; intervals flat, twice as wide as the strial punc- 

 tures, sparsely, very feebly punctulate. Legs short, stout, the 

 femoral teeth minute but distinct on the anterior. Length 3.0-3 2 

 mm. ; width L3 mm. 



Kansas. The three specimens before me exhibit scarcely any 

 variation. This species may be readily known by its pale ochreous 

 color, feebly clouded along the median parts of the elytra, the small 

 size, coarse, subsquamiform vestiture and by several other distinc- 

 tive characters. 



21 D. flisciceps n. sp. — Oblong, rather broad and snbdepressed, pale 

 oclireous-flavate, the head and beak piceons-black ; sterna piceous, each 

 elytron almost imperceptibly clouded with a darker tint in a broad subsutural
