EEVISION OF ELEODIINI BLAISDELL. 243 



Epipleurm moderate in width beneath the humeri, thence f>;rad- 

 iially narrowing to apex ; surface smooth, subopaqne, and usually 

 impunctate. 



^Sterna not strongly punctate and more or less rugulose. 



Paraplc>i?'a' sparsely and obsoleteh^ punctate. 



Abdomen horizontal, obsoletely punctate on first three segments, 

 more strongly so on the fourth and fifth segments. 



Leffs moderate in length, slender to somewhat robust ; anterior 

 femora armed with an acute tooth in both sexes; tibial spurs similar 

 in the sexes, the anterior subequal and acute. The tarsi are simple 

 and similar in the sexes. 



Male. — Elongate and scarcely robust. Elytra somewhat gradually 

 narrowing posteriorly, arcuately and slightly obliquely declivous. 

 Abdomen moderately convex, slightly and broadly impressed on 

 first two segments. 



Female. — Elongate and rather robust. Elytra not noticeably nar- 

 rowed behind and arcuately declivous, abdomen somewhat strongly 

 and evenly convex. 



Measurements. — Males: Length, 19-26 mm.; width, 8-9 mm. Fe- 

 males: Length, 20-28.5 mm.; width, 8-10.8 mm. 



Genital cliaracters., male. — As in gracilis., except that the median 

 groove of the apicale extends to the basal fourth and becomes wider 

 and more membranous. 



Female (Plate 5, fig. 19). — Genital segment trapezoidal, moder- 

 ately robust and sparsely setose. 



Valinda. — Apparently oblique at the apex. Dorsal plate oblong, 

 concave, inner fourth reflexed and glabrous, external three-fourths 

 obliquely and gradually reflexed ; surface glabrous and shining, 

 sparsely punctate and setose, setre moderately short and fine ; external 

 border nearly straight; internal margin arcuate in apical three- 

 fourths thence sinuate to base; apical margin arciiate and at the 

 internal fourth continuous Avith the surface of the apex, angle not 

 evident, each set with a few rather long setso. Apex triangular, with 

 its external border giving the valve an obliquely truncate appearance 

 as it passes into the inferior margin of the fossa, chitino-membranous, 

 setose, setae mostly fine, a few longer on tip. 



Appendage semi-oval, slightly longer than wide, quite evenly 

 rounded, flattened and transverse, finely setose, with a \q.vj loose 

 tuft of longer seta? at apex. Fossa transverse between the apical 

 margin of the dorsal plate and external border of the apex. 



Basal prominences not large but distinct. 



Superior pudendal membrane reaching to about the middle of the 

 dorsal plate and somewhat distantly longitudinally rugulose.
