REVISION OF ELEODIINI BLAISDELL. 373 



Parapleurce somewhat sparsely punctate, hairs short. 



Ahdonu'it horizontal, glabrous and shining, very sparsely punctate, 

 hairs short. 



Leffs comparatively moderate in length and rather slender. 

 Anterior femora mutic ; protibial spurs about similar in the sexes, the 

 anterior a little longer than the posterior; tarsi dissimilar in the 

 sexes. 



Male. — Body rather slender. Antenna^ reaching a short distance 

 beyond the base of the prothorax. Elytra evenly arcuately decli- 

 vous posteriorly. Abdomen moderately convex, first two segments 

 distinctly impressed at middle. Protibial spurs subequal, slender, 

 and acute. Protarsi with the first two joints y&ry feebly thickened 

 at tips beneath, each bearing a small tuft of silken pubescence that 

 ()l)literates the groove. 



Female. — Body rather robust. Antenna^ reaching just slightly 

 beyond the prothoracic base. Elytra rather broadly oval, arcuately 

 and almost vertically declivous posteriorly. Abdomen quite stronglj' 

 convex. Anterior spurs of the protibia? a little longer than the pos- 

 terior, both slightly thickened and acute. Anterior tarsi with the 

 first joint slightly thickened at tip, groove interrupted by a few paler 

 spinules, that are transversely arranged on tip. 



Measurejiients. — Males: Length, 10.2-12.5 mm.; width, 4.2-5 mm. 

 Females: Length, 12-13 mm.; Avidth, 5.2-6 mm. 



Genital characters^ male. — Edeagophore elongately oval and 

 scarcely arched. 



Basale oblong, not three times as long as wide; surface evenly con- 

 vex, with sides feebly arcuate. 



Ajjicule subequilaterally triangular; surface rather strongly con- 

 vex, without groove; sides distinctly sinuate in apical two-thirds, 

 arcuate in basal third; apex more or less attenuate and acute; base 

 broadly lobed at middle and feebly sinuate laterally. 



Sternite transverse. Each lobe triangular, with the external bor- 

 der more or less simuite in basal half, thence more or less obliquely 

 truncate to apex, the latter narrowly rounded; internal border more 

 or less straight; surface feebly convex, sparsely punctate in apical 

 half, setose, setai quite long, still longer on apical margin. Mem- 

 brane not setose across the bottom of the sinus, the latter rather 

 broad. 



Female. — Genital segment elongately triangular, superior surface 

 plane. 



Valvula (Plate 4, fig. 11). — Dorsal plate narrow and elongately 

 oblong: surface plane, glabrous, very sparsely and obsoletely punc- 

 tate, setose; sides subparallel; apical margin evenly rounded and 

 clearly defined from apex, the latter small and finely setose; external 

 lobe obsolete.
