form occurs with the thoracic vittse almost entirely obliterated, the 

 punctuation finer, and the elytra glabrous. 



S. eostipennis n. sp. 



Black, shining, form similar to pertinax but more slender. Rostrum 

 three-fourths as long as the thorax, strongly compressed and slightly 

 broader at tip, at base slightly canaliculate and moderately punctured- 

 Thorax with three rather strongly elevated entire parallel vittse, the 

 lateral with a branch from middle to basal angle, intervals coarsely punc- 

 tured and with luteous coating. Elytra finely striate, stria? with distant, 

 moderately coarse punctures, intervals alternately slightly broader, the 

 broader intervals strongly convex, in their entire length minutely and 

 irregularly biseriately punctate, narrower intervals usually with luteous 

 coating, uniseriately punctate. Pygidium sparsely punctate, punctures 

 near apex submuricate and bearing a short hair, a tuft of hair on each 

 side of apex. Body beneath sparsely punctate. Length .40 inch ; 10 mm. 



A variety occurs with the upper surface red, with the sutural interval 

 and the median thoracic vitta black. The under surface is red varied 

 with black, and the legs also red with the knees black.

Black, shining, usually more attenuate behind. Rostrum nearly as 

 long as thorax, moderately compressed, sparsely and at base more coarsely 

 punctate, above slightly grooved at base, groove broader and deeper 

 behind. Thorax broader than long, apex moderately constricted, gradu- 

 ally wider, % , rapidly broader £ > and sub-parallel to base, the latter 

 feebly bisinuate ; surface with three vittse, the median attaining the 

 apical margin, rapidly dilating to a rhomboid form, and very rarely pro- 

 longed by a very fine line to base, but usually ending abruptly at middle ; 

 latteral vittse sinuous, slightly broader at basal end, and emitting a 

 lateral branch from the middle towards the basal angle, a small smooth 

 callus near the anterior portion of the sides ; spaces between, and to the 

 sides of the vittte coarsely punctured and clothed with a feeble luteous 

 coating. Scutellum longitudinally broadly grooved. Elytra conjointly 

 emarginate, broader behind the base and arcuate! y narrowing to apex ; 

 surface finely striate, striae with rather deeply impressed, coarse, distant 

 punctures, each surrounded with a luteous area, intervals flat, slightly 

 irregular, third strongly elevated, cariuiform at basal half, and with the 

 humeral callus smooth, shining. Pygidium coarsely punctured, with 

 short setae along the middle and a tuft of hairs on each side of apex. 

 Body beneath black, shining, coarsely punctured, mesosternum at sides 

 coarsely foveate. Length .32-. 44 inch ; 8-11 mm. 



This species is one of the most readily recognized species in our fauna. 

 Occurs in the Middle States, rarely ; Gulf States, abundantly.
