REVISION OF ELEODIINI BLAISDELL. 377 



small subacute tuft of yellowish pubescence enveloped by a few ordi- 

 nary spinules, groove distinct on the second joint. 



Female. — Eobust. Antenna? not quite attaining the prothoracic 

 base. P^lytra rather broadly oval, arcuately and vertically declivous 

 l)ehiiid. Abdomen horizontal and rather strongly convex. Anterior 

 Uirsi with the first joint transversely thickened at tip beneath, iuid 

 with a transverse line of piceous spinules upon the same. 



Measurements. — Males: Length, 10-12 mm.; width, 4.5-5.8 mm. 

 Females: Length, 12-13 mm.; width, 6-6.8 nun. 



Genital characters^ male. — Edeagophore flattened oblong-ovate and 

 feebly arched. 



Basale oblong, about Iavo and one-fourth times longer than wide, 

 surface evenly convex, the sides parallel and very feebly arcuate. 



Apicale triangular, surface evenly and not strongly convex, without 

 groove; sides arcuate in basal third, thence broadly and quite strongly 

 sinuate to apex, the latter subacute; base lobed at middle, slightly 

 sinuate laterally. 



Sternite parabolic in outline. Each lobe triangular; external bor- 

 der rather evenly and not strongly arcuate; internal border quite 

 straight ; apex somewhat introrsely placed and rather narrowly 

 rounded ; surface very feebly convex, glabrous and shining, sparsely 

 punctate and setose in apical half, setae moderate in length, longer 

 about apex, membrane not setose across the bottom of the sinus, the 

 latter deep and triangular. 



Fem^aJe. — Genital segment triangular, elongate, about twice as long 

 as wide, surface plane, not conspicuously setose. 



Valvula (Plate 5, fig. 22). — Dorsal plate very elongate, oblong, 

 about four times longer than wide; surface plane, glabrous, very 

 sparsely punctate and setose, seta? fine and inconspicuous; sides par- 

 allel and nearly straight; apical margin parabolically rounded. 

 Apex very small, slightly longer than the appendage, quite narrow 

 and finely setose. 



Appendage mammilliform, about half as large as the apex, with a 

 pencil of about five hairs at tip ; fossa at base of the external surface 

 of the apex. 



Superior pudendal memhrane reaching to the apical fourth of the 

 dorsal plate and longitudinally rugulose. 



Basal promjhiences not evident. 



Ventrolateral surfaces feebly convex from side to side, glabrous, 

 sparsely setose in apical moiety. Each valve very feebly and l)roadly 

 concave apically, submarginal groove broad beneath the laterally 

 prominent external border of the dorsal plate, and quite evanescent 

 before the fossa, which is distinctly lateral in position. Internal 

 margins of the valves contiguous in basal two-thirds; fissure apical 

 and rather narrow. Inferioi" pudendal membrane not visible.
