Hab. — Pennsylvania, Ohio (D. C, Ind., Casey). 



In appearance, form and coloration, this species agrees fully with 

 tesselatus, from which it differs by its greater size, longer second fu- 

 nicular joint, and the approximate claws ; connate very evidently 

 beyond the middle. From morio, to which it bears the closest re- 

 semblance, it differs by its distinctly curved beak, especially marked 

 in the female, and its distinctly broader prothorax. 



S. setulosu!«i 11. sp. — Very similar to the preceding;, witli which it agrees in 

 form and appearance, Init is smaller. It differs as follows : the vestitiire consists 

 of pitchy black, closely matted and adherent scales on the elytra, with a few 

 scattered whitish spots and scales, underside not very densely clothed with very, 

 small, dirty grayish scales; the interstitial setse are long, white, haii-like and 

 quite conspicuous. The b. ak in the male is rather more slender and shining, 

 less densely scaly ; the thoracic punctures rather more coarse, subconfiueut and 

 arranged in somewhat irregular, concentric rows, their interspaces giving a re- 

 semblance to rugse; there is scarcely an indication of a short, basal median 

 vittpe and no lateral spots; the elytral punctures are large and very evident. 

 Length 2.5— O.TS mm. ; 0.10—0.11 inch. 



Hab. — Texas, Illinois. Dr. Horn's and my own collection. 



One specimen has the scales not closely matted, and is more dis- 

 tinctly mottled like the preceding, but the elytral setse and punc- 

 tures are quite conspicuous. Another specimen in Dr. Horn's col- 

 lection from Illinois I refer, with some hesitancy, to the present spe- 

 cies, it is a male and has the beak more evidently tapered to the 

 apex and the elytral setre almost concealed by the incrusted scales. 



H. ciiiertisceiis n. sp. — Subovate, strongly convex, pitchy black, anteniife 

 and legs rufopiceous, underside densely covered with large, broadly oval, over- 

 lapping, yellowish white scales, which, especially on the thoracic side-pieces are 

 darker in the centre and on the abdomen are intermixed with very fine, erect, 

 whitish hairs, on the upper surface smaller, variable in size, gray or grayish 

 brown, scarcely mottled, a little more dense on the sides of the elytra. Beak a 

 little longer ( 9 ) than head and prothorax, feebly curved, somewhat .shining, 

 carinate from base to one-fourth from the apex, strongly punctured and striate 

 each side, nearly glabrous in its apical fifth ; basal tufts obsolete, constriction 

 not deep. Antennae not very slender, inserted at the middle ( 9 ) ; first joint of 

 fnnicle stout, second decidedly shorter, third transverse, outer joints widened ; 

 club rather densely pubescent. Head finely alutaceous, feebly shining, front 

 punctured and sparsely scaly. Prothorax very convex, wider than long, apex 

 about two-thirds as wide as the base; broadly but not strongly constricted at 

 the apex, rather strongly rounded on the sides; surface densely and evenly, 

 though not coarsely punctured, punctures distinct, not confluent and some- 

 what umbilicate, an almost entire, smooth median line, scaly on the sides; 

 scutel very small, glabrous. Elytra less than one-third wider at the base than 

 the prothorax, oval, almost one-half longer than wide at base, sides rounded, 

 widest at the middle, humeri prominent, rounded; distinctly striato-punctate ;
