KEVISION OF ELEODIINI- — BLAISDELL. 273 



Epipleurce moderately wide at the humeri and gradually narrow-

Sterna more or less sparsely punctate and irregularly rugose. 



Parapleunv more or less sparsely punctate.

Legs rather long and quite densely sculptured. All of the femora 

 armed in both sexes with small and more or less acute teeth, the

 in basal third ; anterior tibial spurs about equal in size and length. 

 Tarsi similar in the sexes. 



Male. — Moderately narrow. Antennae attaining the posterior fifth 

 of the prothorax. Elytra strongly attenuate behind, very evenly and 

 very gradually arcuately declivous posteriorly. Abdomen rather 

 strongly convex and feebly or obsoletely impressed at middle of first 

 two segments. Posterior tibia; rather strongly arcuate in basal third. 



Female. — Rather robust. Antennje attaining the posterior fourth 

 of the prothorax. Elytra not strongly attenuated behind, moderately

 vex from side to side. Posterior tibiae not more strongly arcuate than 

 the mesotibise.

 Females: Length, 25 mm.; width, 9.G mm. 



Genital characters., male. — Edeagophore flattened oblong-ovate, very 

 feebly arched in apical half, moderate in size and elongate. 



Basale oblong, evenly convex from side to side, sides evenly and 

 feebly arcuate. 



Apicale rather elongately triangular; surface strongly convex, 

 without or with a very faint median membranous groove; sides feebly 

 sinuate in apical two-thirds or straight; apex more or less produced 

 and rather slender, quite acute; base with a median subacute lobe, 

 quite broadly and distinctly sinuate laterally. 



8ternite transverse. Each lobe subquadrate, with the external bor- 

 der quite straight, meeting the apical margin at somewhat of an 

 angle; apical margin feebly and evenly arcuate and nearly trans- 

 verse, angle introrse and subacute; internal border more or less sinu- 

 ous; surface scarcely convex, subglabrous, finely and evenly but not 

 densely punctate, setose, setae quite long and subequal and not dense.
