Horn.] 4_0 [Sep. 19 



punctate with median fusiform smooth space. Scutellum not canalicu- 

 late. Elytra oval gradually attenuate to tip, scarcely larger than the 

 thorax and head, surface striate, striae with very coarse punctures at 

 basal half, rapidly finer to tip, intervals equal, slightly irregular, and 

 indistinctly uni-seriately punctate. Pygidium very feebly exposed, 

 coarsely 'punctate. Body beneath coarsely but sparsely punctate. Legs 

 finely punctured. Length .32-. 40 inch ; 8-10 mm. 

 Occurs in the Southern States. 



S. arizonensis, n. sp. 



Black, feebly shining. Rostrum longer than half the thorax, moder- 

 ately stout, slightly wider at tip, moderately compressed, sparsely puuc- 

 tulate, at base slightly dilated, more distinctly punctate, and finely 

 grooved. Thorax longer than wide, apex moderately constricted, sides 

 in front strongly arcuate, thence feebly arcuate to base, surface sparsely 

 punctate, punctures coarser toward the middle, and denser at base, 

 a faint trace of smooth median line. Scutellum slightly grooved. Elytra 

 oval, arcuately narrowing to tip, surface finely striate, striae with very 

 coarse punctures in their entire length, intervals flat, equal, finely uni- 

 seriately punctulate. Pygidium moderately strongly elevated along the 

 median line, coarsely sub-muricately punctured, at tip smoother. Body 

 beneath sparsely and finely punctulate, femora very finely punctured. 

 Length .36 inch ; 9 mm. 



A species with very neat appearance, easily known by the above char- 

 acters. 



Occurs in Arizona.

I am not quite certain that these two species are synonymous, as the 

 latter is so briefly described as to be very unsatisfactory. The latter is 

 the older name should they prove identical. 



Black, shining. Rostrum three-fourths the length of thorax, feebly 

 compi'essed, scarcely dilated at base, minutely punctulate, at base finely 

 grooved, groove more deeply impressed between the eyes. Thorax longer 

 than wide, anteriorly constricted, sides moderately arcuate from that to 

 base, surface shining, unequally punctured, punctures sparse and fine over 

 the greater part of the surface, coarser and denser along the base and 

 from the latter coarse punctures extend forwards on each side of the 

 median line, and also slightly within the hind angles, punctures coarse 

 at the apical constriction. Scutellum feebly concave. Elytra oval, 

 scai-cely larger than the head and thorax, rapidly narrowed to apex, sur- 

 face striate, striaa moderately deep, and with coarse punctures gradually 

 evanescent toward the apex, intervals flat, equal, finely punctulate. 

 Pygidium narrow, coarsely punctured, at tip slightly pubescent. Body 

 beneath coarsely and closely punctured, femora minutely punctulate. 

 Length .30 inch ; 7.5 mm. 



Easily known by the shining thorax and rapidly narrowed elytra. 



One specimen from Georgia.
