S. cultellatus, n. sp. 



Body robust, black, opaque. Rostrum longer than half the thorax, 

 straight, strongly compressed, above acutely carinate, especially near the 

 tip, beneath with acute laminiform carina, terminating opposite the 

 scrobes by an abrupt sinuation, surface above coarsely at base densely 

 punctured and slightly canaliculate. Front coarsely punctured. Thorax 

 robust, longer than wide, anteriorly scarcely constricted, sides moder- 

 ately arcuate in front and slightly narrowing to base, surface varolato- 

 punctate, median liue slightly elevated. Scutellum not grooved. Elytra 

 scarcely longer than head and thorax, oval, arcuately, and feebly narrowed 

 to tip, surface deeply and broadly striate, stria? catenulate, intervals 

 narrower than the stria?, alternately broader, the narrower cariniform, 

 the broader bi-seriately punctulate. Pygidium coarsely, muricately punc- 

 tate. Body beneath coarsely but sparsely punctured. Anterior tibia? 

 with strong obtuse spur above the middle, sub-apical mucro wanting, 

 apical slender and longer than usual ; middle and hind tibia? with the 

 spur sub-median. Length .30-. 34 inch ; 7.5-8.5 mm. 



The femora are very robust, the under side of thorax coarsely punc- 

 tured. The form of rostrum will easily distinguish the species. 



Occurs in Kansas and Texas.

Black, feebly shining. Rostrum longer than half the thorax, straight, 

 strongly compressed, above acutely carinate, especially at tip, moderately 

 coarsely punctured, base dilated and with a strong puncture between the 

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

 moderately strongly arcuate to base, surface irregularly punctured, at 

 middle sparsely, coarsely variolato-punctate at the sides and on a line 

 each side of middle converging at base. Scutellum moderately convex. 

 Elytra oval, gradually harrowed to apex, surface striate, stria? not deep, 

 coarsely and rather distantly punctured in their entire length ; intervals 

 equal, at middle more elevated and uni-seriately punctulate. Pygidium 

 cribrate. Body beneath with prothorax and middle nearly smooth, sides 

 and last ventral segment coarsely punctured. Anterior tibia? with strong 

 median oblique tooth, middle and hind tibia? less strongly toothed, tooth 

 sub-median. Length .28-34 inch ; 7-8.5 mm. 



Say and Germar used the name eornpressirostris for two distinct 

 species at nearly the same time, and it is difficult to decide, if date of 

 publication is considered, which should be suppressed. I follow the 

 catalogue of Gemminger and Harold, although they incorrectly place the 

 two names as equivalent. Gyllenhal's caltrirostris is, however, a synonym 

 under any circumstances. 



Occurs from Kansas to Texas.
