 Dcsmons in form but with elytra less inflated. 



296 (- -). SMICRONYX PINGUIS sp. nov. 



Oblong-oval, rather robust. Black, above sparsely clothed with elon- 

 gate-oblong gray scales, those of side pieces beneath slightly broader and 

 more dense; antennae and legs dark reddish-brown. Beak of female one- 

 third longer than head and thorax, slender, cylindrical, feebly but evenly 

 curved, almost impunctate, glabrous, except the small tufts at base. 

 Head glabrous, minutely alutaceous. Thorax one-third wider than long, 

 sides broadly rounded from base to beyond middle, then feebly converging 

 and subparallel to apex; disc finely and sparsely punctate. Elytra oval, 

 at base scarcely one-third wider than thorax, humeri rounded, not pro- 

 minent; sides straight to middle, then broadly rounded to the obtuse apex; 

 striae fine, deep, indistinctly punctate; intervals flat, finely granulate, with- 

 out visible setae, each with two or three rows of the narrow gray scales. 

 Length 2.5 mm. (W. 8. B.) 



Marshall County, Ind., rare; May 28. Larger and more robust 

 than grlseus with broader thorax and less prominent hnmeri, and 

 easily separated from both it and connivens by the finer and 

 sparser vestitnre.

Elongate-oval. Pitchy-black; above rather sparsely clothed with brown- 

 ish and gray intermixed scales; beneath more densely with small oval 

 pale clay-yellow ones; legs piceous. Beak of male shorter than head and 

 thorax, feebly curved, punctured and thinly covered with hair-like scales 

 on basal half; of female longer, shining throughout. Thorax scarcely 

 longer than wide, postocular lobes obsolete, sides rounded, narrowed toward 

 base, apex not constricted, disc densely and confluently punctured. Elytra 

 two-fifths wider at base than thorax, sides nearly straight and parallel to 

 middle; striae finely and distantly punctate; setae of intervals scarcely visi- 

 ble. Length 2.5 mm. 



Described from one pair in the Ulke collection from Virginia. 



298 (10,929). SMICRONYX POSTICUS Dietz, 1894, 150. 



Oblong-oval. Black, rather densely clothed with moderately large, 

 oval, yellowish and grayish-white scales, mottled above with areas of dark- 

 er scales; legs reddish-brown. Beak of female as long as head and thorax, 

 rather densely punctured and scaly on basal half. Thorax more than one- 

 half wider than long, sides strongly rounded; disc coarsely and con- 

 fluently punctured and with an indistinct smooth median line, the inter- 

 vening spaces forming minute concentric ridges. Length 2.5 mm. 



Described from Maryland. Resembles tycJwides but smaller, 

 the beak less robust, scarcely tapering and the scales evenly dis- 

 tributed on the elvtra.
