Last joint of maxillary palpus very decidedly shorter than the preceding. Last 

 joint of labial shorter. 

 Elytra feebly subsulcate posterior to the basal fourth ; anterior tibiae with the 

 upper tooth strong; tibiae and tarsi pitchy black. PI. II, fig. 8. 



ocreatns n. sp. 



Elytra without traces of strise, moderately densely punctured : anterior tibice 



with upper tooth feeble; legs pale brownish testaceous estriatus Lee. 



S. Lecontei Salle {femoralis Lee.) — Piceous, moderately shining, elytra pale 

 eastaneous. Head piceous, deeply and coarsely punctate and with erect brownish 

 hairs. Thorax transverse, narrowed in front, apex slightly prolonged at middle, 

 anterior angles rounded, sides feebly arcuate, hind angles long, slender and not 

 divergent from the line of the sides, base lobed at middle, sinuate each side, surface 

 densely punctate and with erect brown hairs. Elytra elongate, gradually con- 

 vergent posteriorly, dehiscent at apical third, at base gibbous, surface moderately 

 deeply sulcate and subcostate, except at base and moderately densely punctulate, 

 sparsely clothed with short pubescence. Body beneath piceous, clothed with 

 yellowish hair, abdomen less punctate and with fewer hairs. Legs piceous, the 

 femora usually paler. Length .64 — .72 inch; 16 — 18 mm. 



Only males are known. The anterior tibiae have the upper tooth 

 strong. The antennae are serrate. In both the maxillary and labial 

 palpi the terminal joint is longer than the preceding. 



The color of the abdomen varies from piceous to testaceous, the seg- 

 ments often being piceous with the posterior edge of the segments paler. 

 In fully mature specimens the tibiae and tarsi are piceous the femora 

 paler, even pale yellow. 



This is the most abundant species in Texas. 



S, estriatns Lee. — Piceo-testaeeous, less elongate than Lecontei. Head and 

 thorax similar but with shorter yellowish hair. Elytra gibbous at base, without 

 trace of striae or costse, surface moderately densely punctate. Body beneath paler 

 than above and with the legs luteous. Length .56 inch ; 14 mm. 



The anterior tibiae have the upper tooth rather feeble. In the max- 

 illary palpi the last joint is shorter than the preceding, the last joint of 

 the labial is also shorter but less distinctly so than the maxillary. 



Occurs in Texas. 



S. ocreatns n. sp. — Piceous, elytra testaceous, femora yellow. Head and 

 thorax piceous, moderately densely punctate, clothed with moderately long, erect, 

 yellowish hair. Elytra gibbous at base, pale testaceous, sutural and outer margins 

 near the apex bordered with black, surface faintly subcostate posteriorly and not 

 densely nor coarsely punctured, sparsely clothed with very short black pubescence. 

 Body beneath piceous, clothed with yellowish hair. Legs pitchy black, femora 

 yellow. Length .56 inch; 14 mm. PL II, fig. 8. 



Very similar in form to esfriatns^ and therefore shorter and less 

 attenuate than Lecontei. The ant<?rior tibife have the upper tooth well 

 marked. The palpi are its in esfriufiis. 



One specimen, Texas.
