Stexoscelis Woll. 



I refer with doubt the following species to this genus. The rostrum 

 is very short, narrower than the head. Club of antennae round, flattened 

 slightly. The lateral processes of the submentum are more prominent 

 than usual in the preceding genera, and are distinctly visible from above. 



S. brevis Boh. Schon. Gen. Cure. VIII., 2, p. 282. 



Robust, cylindrical, brownish or black, feebly shining. Rostrum short, 

 narrower than the head, moderately coarsely and densely punctured. 

 Thorax broader than long, broadly constricted in front, sides feebly 

 arcuate, base slightly narrower, disc convex, coarsely and densely punc- 

 tured. Elytra cylindrical, parallel, obtusely rounded at apex, surface 

 striate, striae broad, coarsely and serrately punctured, intervals narrower, 

 feebly convex at summit, uneven and with a series of fine punctures 

 distantly placed. Body beneath coarsely and sparsely punctured. Length 

 .12 inch ; 3 mm. 



Described by Boheman as Rhyncolus. Resembles Hylastes in form, and 

 also, from the figure, Stenoscelis hylastoides Woll. (Journ. Ent. Vol. I., 

 pi. XL, fig. 1), except that the sides of the thorax are more nearly parallel 

 at middle, and the basal angles rounded. 



Occurs from New York to Florida. 



To this genus the following probably belongs : 



Rhyncolus latinasus Say. Desc. Cure. X. A. p. 30 ; Am. Ent. edit. 

 Lee. I., p. 299 ; Boh. Schonh. Gen. Cure. IV., p. 1068. 



" Subdepressus, niger, glaber, antennarum clava pedibusque rufo- 

 ferrugiueis ; rostro brevi latitudine fere capitis, sublineari, thorace 

 oblongo profunde sub-disperse punctato, obsoletissime carinato ; elytris 

 rufo-castaneis, confertim punctato striatis, interstitiis angustis, convexis." 



Front with slight fovea. Apical margin of thorax slightly elevated 

 at middle. Length .10 inch (Say). 



Occurs in Florida. Unknown to me.

Male. Abdomen apparently with six segments. 



The sixth segment is really the pygidium which projects beyond the 

 corresponding ventral segment, its lower margin being thickened and 

 simulating in its construction a true ventral segment. The anal opening 

 may be seen in the suture between it and the fifth ventral. The latter 

 segment is shorter than those which precede and its posterior margin 

 straight. The dorsal segments of the abdomen are eight in number. 



Female. Abdomen with five segments.
