Goleopterolugical Notices, VII. 65 1 



Body stout, the elytral intervals very broad when compared with the striae. 



Last ventral segment of the female unimpressed and clothed with long 



dense vestiture to the apex. 



Elytral vestiture strongly variegated or irregularly tesselate; beak of 



the female subcarinate above for a considerable distance from the base. 



Massachusetts o1>tusus Blanch. 



Elytral vestiture feebly variegated or nearly uniform, the beak of the 

 female feebly carinate only at the extreme base. New Mexico. 



IbrcTirostris n. sp. 

 Last ventral of the female impressed at the middle, the vestiture becom- 

 ing shorter, as well as hair-like, toward tip ; elytral vestiture strongly 

 variegated monticola n. sp. 



These short-beaked species probably feed upon nuts having thin 

 and exposed shells, such as acorns, and this circumstance, if true, 

 will account for their greater variety and numbers, the oaks being 

 numerous in species and having widely varying characteristics, 

 which must exert more or less influence in evolving what we 

 designate species among the depredating insects. The new spe- 

 cies are described below in order. 



B. liiimeralis. — Very stout and thick, subrhomboidal; integuments dark 

 piceo-rufous in color, the prothorax piceous-black ; vestiture moderately dense, 

 nearly uniform, pale ochreous in color, the scales on the pronotum slender 

 and directed transversely. Head scarcely more than % as wide as the pro- 

 thorax, the eyes separated by nearly % of their own width, the intermediate 

 surface with a small rounded puncture; beak equal in length to the elytra, 

 moderately slender, evenly and distinctly arcuate throughout the length, 

 punctate and feebly carinate above toward base, the antenna inserted just be- 

 hind the middle; first four funicular joints decreasing rather rapidly in length, 

 the club elongate-fusiform, very densely pubescent. Prothorax relatively 

 rather small, short, fully }4 wider than long, the sides subparallel and very 

 feebly arcuate to near the apex, then rapidly rounded and sinuate to the dis- 

 tinctly tubulate and truncate apex; base broadly lobed at the middle; surface 

 moderately convex, densely and somewhat coarsely punctured. Elytra short, 

 not longer than wide, twice as long as the prothorax and fully % wider, the 

 sides rapidly convergent and very feebly arcuate from the rather widely ex- 

 posed and prominent humeri, the apex parabolic; striae moderately coarse, 

 deep, strongly and somewhat distantly punctate, the intervals wide and feebly 

 convex, strongly and closely punctato-rugose. Legs rather stout. Length 

 (exclusive of the beak) 6.5 mm.; width 3.5 mm. 



Florida. 



This distinct and isolated species is described from the male, 

 the abdomen being strongly impressed toward the middle of the 

 two basal segments ; the fifth segment is narrowly and feebly 

 sinuate at tip, with the surface feebly impressed, subtumid at each
