REVISION OF ELEODIINI BLAISDELL. 177 



Genital characters, male. — Edeagophore oblong-ovate as usual and 

 not arched. 



Basale short oblong, evenly convex, with the sides more or less 

 arcuate. 



Ajyicale triangular, nearly twice as long as wide; surface evenly 

 convex. Avith a median groove at middle four-sixths, gradually dilat- 

 ing from the middle to base; sides feebly arcuate in basal third, 

 thence very feebly siiuuite to apex, the latter acute; base rather 

 broadly lobed at the middle and more or less sinuate laterally. 



Sternitc transverse. Each lobe rather short, with the external bor- 

 der more or less straight in basal half, thence evenly and broadly 

 arcuate to the internal border, angle scarcely evident; internal bor- 

 der broadly membrano-chitinous and not defined ; surface feebly con- 

 vex, sloping inward from the middle to the sinus, glabrous in basal 

 and external third, elsewhere punctate and setose; punctures and 

 hairs sparsely placed, the latter rather long. Sinus narrow and 

 closed by membrane; the latter may be more or less setose. 



Female. — Genital segment quadrate in outline, rather short, setose 

 and not deflexed apically. 



Vol Villa (Plate 4, fig. 4). — Dorsal plate more or less broadly obo- 

 vate, with the internal third in apical half reflexed, impunctate, and 

 glabrous; surface more or less oblique in the outer two-thirds, and 

 consecpiently rather concave, coarsely and sparsely punctate, seta? mod- 

 erate in length and more or less, flying; external border more or less 

 arcuate and continuously so with the arcuate apical margin, angle 

 scarcely evident; internal border arcuate in apical half, thence to 

 base more or less sinuate. Apex small and triangular, subacute, finely 

 setose, and continuous with the reflexed internal border of the dorsal 

 plate. 



Superior pudendal memhrane reaching to about the middle of the 

 dorsal plate, and reflexed apicall}^ to be directly continuous with 

 the valvular membrane, fornix absent, irregularly and obsoletely 

 rugulose. 



Veutrolateral surfaces. — Body semicircularly and evenly convex 

 and glabrous, rather strongly impressed across the bases of the 

 apices; submarginal groove broad and arcuate to the internal 

 margin of the fossa, beneath the more or less explanate external and 

 apical border of each dorsal plate and fossa, sparsely setose; internal 

 border of the valves contiguous in the basal fourth. Genital fissure 

 long and narrowly fusiform with the inferior pudendal membrane 

 visible in the basal half.
