EEVISION OF ELEODIINI BLAISDELL. 197 



joint of the protarsi obliquely produced beneath and clothed with 

 short pubescence at tip, forming an acute transverse tuft, groove 

 apparently obliterated. 



Measurement. — Males: Length, 28-35 mm.; width, 13-15 mm. 

 Females: Length, 30-33 mm.; width, 13.5-16.2 mm. 



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

 form. 



Basale oblong, stout, and more or less arched, variable. 



Apicale slightly longer than wide, triangular, sides straight to 

 feebly arcuate, becoming slightly sinuate before the apex, the latter 

 somewhat produced and acute; base broadly lobed at middle and 

 more or less sinuate laterally; surface evenly convex, grooved at mid- 

 dle three-fifths, groove more or less linear, with sides impressed, 

 forming a fusiform depression. 



Sternite broader than long. Lobes moderate, each with the exter- 

 nal border rather broadly arcuate; apex obtuse, and the internal 

 border is short and quite straight; surface densely punctate in apical 

 half, densely setose in apical third, setse moderately long and not 

 extending upon the membrane across the bottom of the sinus, the 

 latter nearly closed by the former. The lobes are separated centrally 

 at base by a transversely oval membranous area, just cephalad to the 

 sinus, the inner borders of the lobes at base are thus rendered semi- 

 circularly sinuate. 



Female. — Genital segment subtrapezoidal, robust, rather strongly, 

 sparsely punctuate and setose ; setae rather long, flying, semi-erect, and 

 quite evenly distributed. 



Valvula (Plate 1, fig. 17). — Dorsal plate oblong, with sides quite 

 strongly reflexed and parallel, scarcely retracted; external border 

 quite straight ; internal slightly angulate and sinuate near base ; api- 

 cal margin quite truncate, angle evident and set with longer seta^ ; sur- 

 face strongly concave. Submarginal groove shallow and broad at 

 base, visible from above but less strongly defined toward apex. Apex 

 short, finely setose, and noticeably longer than the appendage. 



Basal pronvmences strongly developed and setose. 



Appendage short, not prominent, conical, setose, with a loose pencil 

 of quite long sette at tip. 



Valvular membrane more or less visible in the intervalvular space, 

 caudad to the pudendal membranes. 



Superior pudendal mem^hrane reaching about midway between the 

 base and apex, not longitudinally rugulose. 



Ventrolateixd surfaces not very strongly inflated, setose in apical 

 half, scarcely transversely concave before the apex ; internal margins 

 of the valves contiguous in basal half, genital fissure rather widely 

 fusiform and the inferior pudendal membrane is not visible.
