Hern.] 4bL [Sep. 19, 



(the terminal especially) punctured. Legs black, tarsi pale rufo-testa- 

 ceous. Length .10-.12 inch ; 2.5-3 ram. 



This species may be readily known by the six-jointed funicle of the 

 antennae and by the pubescence of the surface sparsely placed, very in- 

 conspicuous even with the lens, and without any tendency to form a 

 design. The antennae vary somewhat in color, but are never black. 

 The tarsi are always pale rufo-testaceous. 



Three specimens before me are from Illinois, and another from near 

 Puget Sound. 



O. niger n. sp. 



Black, sub-opacme, surface clothed with nearly black, recumbent 

 pubescence, elytra with faint pruinose transverse band at one third 

 from base. Rostrum cylindrical, as long as head and thorax, moderately 

 punctured over its entire surface. Antennae piceous, inserted near the 

 middle of the rostrum. Thorax broader than long, narrower in front, 

 sides moderately arcuate, base slightly narrowed, surface coarsely, 

 deeply, and moderately densely punctured, sparsely clothed with brownish 

 pubescence, with a few cinereous hairs along the middle and sides. 

 Scutellum densely clothed with silvery-white hairs. Elytra moderately 

 robust, slightly longer than wide, one-half wider at base than the thorax; 

 surface moderately deeply striate, striae coarsely punctured, intervals 

 flat, rugulose, clothed with short, recumbent, brownish pubescence, and 

 an irregular transverse pruinose band near the basal third. Body beneath 

 and legs black, shining, abdomen moderately coarsely punctured. 

 Length .08-. 10 inch ; 2-2.5 mm. 



The conspicuously white scutellum is a notable feature in this species. 



Occurs in Xova Scotia, Canada, and Illinois. 



O. subhirtus, n. sp. 



Black, feebly shining, surface moderately clothed with brownish hair, 

 and with grayish hair forming an irregulai band near the basal third, 

 broadest at suture, and a narrower band near the apex of irregular form 

 and much narrower than the preceding. Rostrum cylindrical, moderately 

 arcuate, coarsely punctured. Antennae testaceous, inserted near the 

 middle of the rostrum. Thorax nearly three-fourths wider than long, 

 sides moderately arcuate, apex narrower than base, surface opaque, 

 sparsely rugosely punctured, and very sparsely cinereo-pubescent. Scu- 

 tellum cinereo-pubescent. Elytra oval, longer than wide, at base one- 

 third broader than the thorax, striate, striae coarsely punctured, intervals 

 flat, rugulose, surface sparsely clothed with dark brownish pubescence; 

 and with an irregular sub-basal band of cinereous pubescence broadest 

 at the suture, anterior and posterior margins sinuous, and a sub-apical 

 narrower band. Body beneath black, sparsely pubescent, moderately 

 punctured and shining. Legs piceous-black, tarsi pale testaceous. 

 Length .08 inch ; 2 mm. 



The pubescence clothing the surface is coarser than in the other species
