REVISION OF ELEODIINI BLAISDELL. 447 



with the first two joints feebh'^ but distinctly thickened at tips beneath, 

 each bearing a small tuft of spinules at the apico-marginal angles, the 

 second joint is less thickened than the first, in each instance obliter- 

 ating the plantar groove. 



Female. — Body quite broadly oval. Elytra rather evenly arcuately 

 declivous posteriorly. Abdomen rather strongly convex from side 

 to side. Protarsi with the first joint slightly thickened at tip beneath, 

 bearing a small tuft of spinules. 



Measurements. — Males: Length, 16-20 mm.; width, 6.8-8 mm. 

 Females: Length, 16,2-19.5 mm.; width, 7.5-9 mm. 



Genital characters., male. — Edeagophore rather small, narrow, 

 oblong-ovate, slightly arched. 



Basale oblong; surface not strongly convex, flattened more or less 

 on the dorsum, sides nearly parallel. 



A'picale triangular, about one-half longer than Avide, apical fourth 

 more or less decurved; surface flattened, wdth a broad median mem- 

 branous groove in basal half; sides nearly straight to tip, the latter 

 broad and narrowly rounded; base rather narrowly lobed at middle 

 and sinuate laterally. 



Sternite slightly transversely quadrate in outline. Each lobe rather 

 long, with external border straight or slightly sinuate in basal half, 

 thence evenly arcuate to apex; internal border symmetrically curv^ed 

 with the external border, both borders meeting in a rather narrowly 

 rounded apex; surface very feebly convex, smooth, impunctate, and 

 glabrous in basal moiety, apically coarsely and sparsely punctate, 

 not densely setose, setse quite long. Sinus triangular, slightly closed 

 at bottom by membrane which is not setose. 



Female. — Genital segment (Plate 5, fig. 6) triangular in outline, 

 about one-half longer than wide, strongly chitinized, glabrous, valves 

 contiguous. 



Valvula. — Dorsal plate elongately triangular, impunctate; surface 

 directed slightly outward as well as upward; external border quite 

 straight, slightly convergent to apex; apical border oblique, angle 

 rounded, internally continuous with the chitinous apex, the latter 

 produced, moderately excurved, convex from side to side and concave 

 beneath, thin and sublaminate at tip, where it is rather broad and 

 rounded, internal surface moderately and finely setose, dorsally 

 without setse. 



Appendage small and conical, bearing three or four long setae at 

 tip; fossa an excavation at base of the external surface of apex 

 and contiguous to the apical border of the dorsal plate. 



Superior pudendal membrane attaining the apical third of the 

 dorsal plate and more or less longitudinally rugulose. 



Basal prominences not developed.
