Oval, robust, convex species having the surface black, shin- 

 ing, subglabrous; beak strongly curved, usually tapering from 

 base to apex; antenna] club very large, nearly as long as the en-

KKY TO EASTEUX SPECIES OF STKTIIORAKTS. 



. Sides of thorax broadly curved, the punctures of disc rather fine, 

 widely separated; those on sides beneath coarse, not 'str'igose. 



625. CORPUI.ENTA. 

 aa. Thorax smaller and more conical, its sides converging from the base; 



the punctures larger and less sparse. 



li. Sides of thorax beneath obliquely and finely strigose; disc with a 

 narrow, entire median smooth line; punctures of elytral intervals 

 in part confused. 

 c. Strise of elytra strongly punctate, their edges crenulate. 



626. INCOMPTA. 

 cc. Strise finely punctate at bottom, their edges not crenulate. 



627. COMMIXTA. 

 l)lj. Sides of thorax distinctly punctate, not strigose beneath; disc with 



interrupted median smooth line; punctures of intervals very fine 

 and in a single row. 628. OVATA. 



625 (8911). STETHOIJAKIS COIUTLEXTA Lee., 1876, 420. 



Broadly oval. Black, glabrous, strongly shining; antenna? and legs 

 piceous. Beak stout, cylindrical, polished, as long as thorax, finely and 

 sparsely punctate. Thorax short, very convex, four-fifths wider than long, 

 strongly tubulate at apex, punctured as given in key, the median smooth 

 line entire. Elytra behind humeri one-fifth wider than thorax, striae coarse, 

 deep, their sides crenulate on basal half; punctures of intervals very fine, 

 sparse, and confused. Beneath coarsely, the abdomen more finely, punc- 

 tate; third and fourth ventrals with a single transverse row of punctures. 

 Length 3.33.5 mm. 



Baysenger, Fla., Feb. l'S ; rare Taken at Tampa and Lake 

 Ashley by Schwa rx. Recorded also from Michigan and District 

 of Columbia, but these records probably based on specimens of 

 incompta. 



626 (11,199). STETHOP.AIMS IXCOMPTA Casey, 1892, 655. 



Oval, convex. Black, strongly shining. Beak strongly curved, as long 

 as head and thorax, densely punctured on the sides. Thorax two-thirds 

 wider than long, disc rather finely, deeply, not densely punctate. Interval? 

 of elytra differing greatly in width, the third twice as wide as the grooves.
