NORTH AMERICAN COLEOPTKRA. 125 



Closely aliierl to condridu^t and sordidus, from which it differs by 

 its rather large size, the relatively longer second funicular joint and 

 the formation of the prothorax ; the color of the derm is of a red- 

 dish brown color. 



I>. pervisiis n. sp. — Elongate oval, pitchy black, distal lialf of rostruin, 

 antemi{« and legs rufous, not very densely clothed with snjall, oval, grayish 

 white scales. Beak long and slender, regularly curved, less so in the male, cj'- 

 lindrical, basal constriction moderately deep, tufts small, distinct. Male: dis- 

 tinctly punctured and rather densely scaly from base to the antennal insertion, 

 finely subcarinate, distal two-fifths nearly smooth, finely punctulate; scrobes 

 commencing two-fifths from the apex, distinctly oblique. Female: more finely 

 punctured and less densely scaly for fully one-third from the base, subcarinate; 

 antenna; inserted two-fifths ( % ) from the apex or one-third ( 9 ) from the base, 

 first and second joints of funicle elongate, slender and equal iu length; clava 

 rather elongate ovate, densely pubescent. Head finely punctured and sparsely 

 squamous. Prothorax wider than lo!>g, moderately narrowed in front, rather 

 broadly and feebly constricted at the apex, regularly and rather strongly rounded 

 on the sides; surface rather coarsely and not very densely punctured, median 

 smooth line well defined, extending from the anterior margin for three-fifths the 

 length of the prothorax. Elytra less than one third and rather suddenly wider 

 than the prothorax at its base and nearly twice as long as wide, very feebly 

 rounded on the sides, humeri prominent; strife distinct, approximately though 

 not very distinctly punctate; interspaces not wide, of equal width throughout, 

 except at the base, where the second and third are a little wider, suberect setae 

 very small, inconspicuous, a short pale vitta at the base of the third interspace. 

 Prosternum transversely impressed, postocular lobes obsolete. Legs not very 

 slender; tibiae moderately widened towards the apex, more so the posterior; 

 tarsi rather stout, first joint scarcely longer than wide, third broadly bilobed, 

 fourth not very long; claws small, connate in basal third. Length 3.0 — 3.25 

 mm, ; 0.12—0.13 inch. 



Hab. — Dakota. One male and three females in Dr. Horn's coll. 



A very distinct species ; might be confounded with coiistricttis and 

 sordidus, from which it differs in the first and second funicular joints 

 being equal, the beak not impressed before the basal constriction, 

 the prominent humeri, the white basal line on the third interspace, 

 the somewhat stouter tibia; and dilated tarsi, and the antennal club 

 entirely pubescent. 



I*. iiicortii»i n. sp. — Oblong elli|)tic, piceous, antennae and legs rufous; 

 densely clothed with rather large, oval, grayish or pale ochreous scales. Beak 

 and antennae as in the preceding species. Head punctured and scaly. Protho- 

 rax as long as wide, moderately narrowed in front scarcely constricted at the 

 apex, feebly rounded on the sides, a trifle wider at the middle than at the base ; 

 sparsely and finely punctured along the middle, n:ore densely on the sides, punc- 

 tures more or less concealed by the scales except along the middle third, wheie 

 the scaly vestiture is less dense, dorsal smooth line obsolete. Elytra nearly one-
