seventh interval. Pygidium coarsely but sparsely punctured, 'with an 

 oblique line of short yellowish hairs on each side. Body beneath very 

 coarsely and densely punctured. Length .30-. 36 inch ; 7.5-9 mm. 



The tibiae of both sexes are simple. 



Occurs in Middle States, Georgia and Kansas. 



f?. scoparius, n. sp. 



Agrees with the preceding in form, and differs as follows : 



Thoracic vittae, sub-obsolete, sparsely punctulate, intervals coarsely 

 punctured. Elytra finely striate and with coarse foveate punctures be- 

 coming finer toward apex, intervals slightly alternating the wider bi- 

 seriately, the narrower uni-seriately punctulate. Pygidium coarsely 

 punctured, and with a slight tuft of hairs at apex on each side. Body 

 beneath coarsely punctured. Length .36 inch ; 9 mm. 



Male. Hind tibial stout, strongly angulate at middle of inner margin, 

 and with a long dense brush of hairs at angulation and less densely 

 pubescent from thence to apex. 



Female. Tibiae normal. 



Two specimens, Wisconsin and Kansas. 



Resembles also superficially some of the smaller varieties of S. pertinax, 

 but the tarsal and sexual characters at once serve to distinguish it. 



S. eallosus Oliv. Ent. V., 83, p. 92, pi. 28, fig. 416 ; Gyll., Schonh., 

 Cure. IV., p. 942. 



Black, body above and beneath at sides, densely clothed with brownish 

 argillaceous coating. Rostrum two thirds the length of thorax, mod- 

 erately compressed, above punctured, at base sub-canaliculate and more 

 coarsely punctured. Thorax similar in form to that of zece, base much 

 more distinctly lobed at middle, vittae very indistinctly limited, their 

 position indicated by very coarse variolate punctures, the median vitta 

 incomplete posteriorly. Scutellum broadly transversely concave. Elytra 

 oval gradually narrowed to apex, base feebly emarginate ; surface irregu- 

 lar, finely striate, striae coarsely foveato-punctate, third interval at base 

 obtusely elevated, callus at tip of seventh interval moderately elevated. 

 Pygidium coarsely punctured, apex on each side with slight tuft of hairs. 

 Body beneath coarsely but very sparsely foveato-punctate. Length .48 

 inch ; 12 mm. 



This species resembles a cicatricosus which has become coated with 

 mud, but the well-marked thoracic vittae and the absence of variolate 

 punctures in the latter at once distinguish it. 



Occurs in the Gulf and Western States. 



S. sculptilis Uhler. Proc. Acad., 1855, p. 416. 



Body black, above entirely covered with dense argillaceous coating 

 ochreous or pale brownish in color. Rostrum naked at tip, coated at 

 base, two-thirds the length of thorax, sparsely and at base more densely 

 and coarsely punctured. Thorax similar in form to sea', densely coated 

 and with the vittae moderately well marked ; median broadly dilated at
