EEVISTON OF ELEODIINI BLAISDELL. 319 



pubescence at tips beneath, tuft of the second joints about one-half 

 the size of the first. 



Female. — Rather robust, antennae scarcely attaining the base of 

 the prothorax. Elytra somewhat broadly oval, arcuately and more 

 or less vertically declivous behind. Abdomen horizontal, and rather 

 strongly convex. Anterior tarsi without golden pubescence on the 

 first two joints beneath, the produced tips clothed with the ordinary 

 ferrugineous spinules that may interrupt the groove. 



Measurenunts. — Males: Length, 14-17.5 mm.; width, 6-7 mm. 

 FeTTioles: Length, 15.2-18 mm.; Avidth, 7-8.5 mm. 



Genital characters^ male. — Edeagophore oblong fusiform ; not 

 arched. 



Basale oblong, scarcely three times as long as Avide, evenly convex ; 

 sides quite parallel. 



Apicale small, nearly equilaterally triangular; surface moderately 

 convex, without groove; sides more or less sinuate, tip acute; base 

 broadly lobed, feeblv sinuate laterally. 



Sternite transversely quadrate. Each lobe long and narrow, tri- 

 angular; external margin sinuate basally, obliquely arcuate apically; 

 apex very narrowly rounded; internal border quite straight; sur- 

 face very feebl}^ convex, rather densely punctate in apical half, 

 setose, seta3 moderately long. Membrane not setose across the bot- 

 tom of the sinus, the latter broad. 



Female. — Genital segment triangular, slightly longer than wide, 

 superior surface plane. 



Valoula (Plate 4, fig. 12). — Dorsal plate very slightly narrowed 

 from base to apex, sides feebly convergent or parallel ; surface plane, 

 glabrous, sparsely punctate, setse not evident ; margins nearly straight ; 

 apical margin more or less evenly rounded, often rather prominent 

 internally. Apex long and slender, sometimes moderate, subacute, 

 external lobe obsolete, finely setose. 



Appendage short mammilliform, clothed wath a few, short setae, 

 three or four longer ones at tip. Fossa at the base and external sur- 

 face of apex. 



Basal prominences not evident. 



Superior pudendal meynhrane reaching to near the apical margin 

 of the dorsal plate, longitudinally rugulose. 



Ventrolateral surfaces as in tenehrosa.
