REVISION OF ELEODIINI BLAISDELL. 227 



Female. — Rather robust. Antenniv reaching scarcely to the protho- 

 racic base. Elj'tra somewhat suddenh" obliquel}^ declivous posteriorly 

 and sinuate at base of apex. Cauda equal to about one-eleventh of 

 the entire elytral length. Abdomen quite strongly ventricose to the 

 fourth segment. Anterior femora quite mutic. 



Measurements without and with the cauda. — Males: Length, 21 

 and 24; 25 and 29.5 mm. ; width, 8-10 mm. Females: Length, 22 and 

 24 ; 26.5 and 29.5 mm. ; width, 9.5-12 mm. 



Genital characters^ male. — Edeagophore of the usual oblong-ovate 

 form. 



Basale short and oblong, subequal in length to the apicale. 



Apicale elongate and suboblong-triangular, moderately convex and 

 slightly flattened, with a linear membranous groove in middle third; 

 sides parallel in basal half, thence arcuate, becoming slightly sinuate 

 at apex, the latter acute and slightly produced ; base arcuate, scarcely 

 sinuate laterally. 



Stc7iiite subquadrate. Each lobe about twice as long as wide, 

 broadly rounded at apex; external margin nearly straight; internal 

 margin rather arcuate; surface glabrous, not very thickly punctate 

 and setose, seta? moderately long. 



Female. — Genital segment triangular, subtruncate, length about 

 equal to the width at base. 



Valvula (Plate 4, fig, 7). — Dorsal plate oblong with the surface 

 broadly concave, margins reflexed and nearly parallel ; surface finely 

 punctured in apical tw^o-thirds, each puncture bearing a short semi- 

 recumbent seta; external border nearly straight; internal margin 

 slightly sinuous: apical margin more or less oblique, asperate, set 

 with moderately long and evenly distributed setae, which are not 

 longer at the angle, the latter more or less rounded and never promi- 

 nent. Apex membrano-chitinous, scarcely longer than the append- 

 age, acute ; surface set with fine seta^, apical tuft rather short. 



Appendage chitinous, conical, quite long and nearly as long ab 

 the apex, blunt, and asperate in apical half, set with rather long setaj, 

 tuft at tip quite long. 



Superior pudendal membrane scarcely reaching one-third from the 

 base. 



Ventrolateral surfaces. — Body moderately convex but not notice- 

 ably inflated, slightly and transversely concave before the apices, 

 finely punctate and set with verj^ fine, short setaj in apical two-thirds. 

 Submarginal groove obsolete. External margin of the dorsal plate 

 not prominent laterally. Genital fissure long and fusiform, wdth the 

 inferior pudend-al membrane visible in basal half.
