EEVISION OF ELEODIINT BLAISDELL. 83 



Legs moderate, strongly punctate, anterior femora mutic; anterior 

 tibial spurs dissimilar; first joint of the anterior tarsi slightly thick- 

 ened at tip beneath. 



Male. — Oblong-ovate, comparatively narrow, sometimes subcylin- 

 drical. Antenna* reaching to the base of the prothorax. Elytra 

 rather narrowly oblong-oval, gradually narrowed in apical fourth, 

 lircuately and slightly obliquely declivous behind. Abdomen dis- 

 tinctly oblique, very moderately convex and broadly impressed at 

 iniddle of the first two segments. Femora sometimes slightly thick- 

 ened; anterior tibial spurs rather short, the anterior about one-half 

 longer than the jDosterior, feebly thickened and gradually narrowed 

 from base to apex, acute. Anterior tarsi with a tuft of spinules on 

 the thickened tip beneath, the pencil of modified spinules scarcely 

 evident. 



Female. — Body robust, ovate, antenna^ not reaching the base of the 

 prothorax. Elytra broadly oval, frequently inflated, moderately nar- 

 rowed at posterior sixth, arcuately and vertically declivous behind. 

 Abdomen horizontal and strongly convex. Anterior spurs of the 

 anterior tibia^ robust and broad, at least twice as long as the posterior, 

 sides arcuate and parallel, narrowed in about apical fourth and sub- 

 acute. Anterior tarsi with a small transverse tuft of ordinary spi- 

 nules on the thickened tip of the first joint beneath. 



Measurements. — Males: Length, 16.5-21 mm.; width, 6-7.5 mm. 

 Females: Length, 17.5-24 mm.; width, 8-12 mm. 



Genital characters^ male. — Edeagophore (Plate 2, fig. 8) fusiform 

 to flattened oblong-ovate, rather stout and arched. 



Basale oblong; surface rather strongly convex, sides more or less 

 arcuate. 



Apicale triangular, slightly elongate; surface somewhat strongly 

 and evenly convex, with a median membranous groove in apical half; 

 sides feebly arcuate in basal half, thence broadly and feebly sinuate 

 to apex, the latter somewhat narrow and acute; base with a small 

 rounded lobe at middle and broadly sinuate laterally. 



Sternite (Plate 2, fig. 5) transverse. Each lobe slightly quadrate, 

 with the external border quite straight in basal half, thence broadly 

 arcuate to apex, angle narrowly rounded; internal border quite 

 straight; surface moderately convex, sparsely and strongly punctate, 

 setose, seta? moderate, longer and denser in apical area. Membrane 

 sparsely setose at bottom of the sinus, the latter broad. 



Female. — Genital segment (Plate 2, fig. 6) quadrate, not deflexed 

 apically and setose. 



Valcula. — Dorsal plate oblong, slightly narrowing toward apex, 

 explanate externally and at apex; surface nearly plane, impunctate 

 in basal half, elsewhere sparsely punctate and setose, setae rather 

 short and reclining; external border nearly straight, converging
