1S73.] 4:—i [Horn. 



erately arcuate, sub-parallel or feebly arcuate to base ; surface coarsely 

 punctured, somewhat more densely in front, and with a fine, smooth 

 median line. Scutellum not canaliculate, elytra oblong, slightly atten- 

 uate posteriorly, deeply striate, stria; not distinctly punctured, intervals 

 Hat, equal, very finely alutaceous, and with a single row of very coarse 

 sub-quadrate punctures closely placed. Pygidium coarsely and equally 

 punctured, sparsely pubescent at tip. Body beneath black, coarsely and 

 sparsely punctured, legs piceous or rufous. Length .30-. 84 inch ; 75- 

 8.5 mm. 



The color is sometimes piceous, frequently castaneous, and in some 

 specimens the thorax is piceous, and has on each side of the median 

 smooth line a linear rufous space, and a similar space adjacent to the 

 lateral margin. 



Occurs in California. 



S. parvulus Gyll. Schonh. Gen. Cure. IV., p. 961. 



Black, with cinereous coating of argillaceous material. Rostrum 

 three-fourths as long as thorax, sparsely punctate, base dilated over the 

 scrobes, coarsely punctured, and moderately deeply canaliculate. Thorax 

 moderately constricted at apex, sides in front strongly, thence moderately 

 arcuate to base, surface densely and coarsely punctured, rarely with 

 trace of median line, and at base a slight trace of oblique impression on 

 each side of middle. Scutellum not channelled. Elytra oval, moder- 

 ately narrowed to tip, surface finely striate, striae with coarse punctures 

 moderately distantly placed, gradually finer to tip, intervals slightly 

 alternating in width and convexity, uni-seriately and rather coarsely 

 punctate. Pygidium "coarsely puuetate, slightly fimbriate at apex. 

 Body beneath coarsely, but not densely punctured. Legs coarsely punc- 

 tate. Length .24 inch ; 6 mm. 



The smallest species in our fauna, easily known by the above charac- 

 ters. 



Occurs in Pennsylvania, Georgia and Kansas. 



S. pumilus Gyll. Schonh. Gen. Cure. IV., p. 960. 



" Oblongo-ellipticus, parum convexus, niger, opacus, sparsim cinereo- 

 pulverulentus ; thorace dense varioloso-punetato, in medio suboa/rinato ; 

 < lytris obsolete, remote punctato-striatis ; interstitiis plants, nix punclulatis, 

 guttulis cinereis in'oratis." 



Similar to S. parculus, but twice as large. 



This species is unknown to me. It is placed next to parvulus by 

 Gyllenhal. 



S. retusus Gyll, Schonh. Gen. Cure. IV., p. 949. 



Body robust, black, sub-opaque. Rostrum half the length of thorax, 

 slightly arcuate, moderately compressed, aud gradually broader to tip, 

 sparsely punctulate between the eyes, flattened and deeply canaliculate. 

 Thorax robust, slightly longer than wide, feebly constricted at apex, 

 sides gradually arcuate, base slightly narrower, surface coarsely variolato-
