REVISION OF ELEODIINI BLATSDELL. 107 



Stemite transversely parabolic. Each lobe with the outer border 

 evenly arcuate ; apex more or less rounded ; internal border more or less 

 straight; surface feebly convex, shining, sparsely to rather densely 

 punctate, setose, setae not dense and moderate in length. Membrane 

 slightl}^ setose across the bottom of the sinus, the latter moderate in 

 size. 



Female. — Genital segment quadrate, slightly longer than wide, 

 with a slight antero-posterior convexity, setose. 



Valvula (Plate 3, fig. 20). — Dorsal plate oblong, varying more or 

 less in width. Surface glabrous and shining, plane to feebly concave, 

 sparsely punctate in apical half and along the internal moiety to 

 base, setae rather short ; sides subparallel ; outer lobe of apex not 

 differentiated from the apical margin of the plate, evenly rounded, 

 well developed, scarcely defined from the very small and hardly visible 

 internal lobe. The valvular apex obliquely and inwardly truncate, 

 sometimes very slightly sinuate at the inner third, apical area set 

 with rather long and flying seta\ 



Appendage small and conical, partly visible from above, directed 

 backward and more or less inward. 



Siiperuyr jnidendal membrane long, reaching to the base of the in- 

 ternal lobe of the apex, and longitudinally rugulose. 



Ventrolateral surface more or less evenly and moderately convex, 

 sparsely punctate and setose, setae rather short; submarginal groove 

 arcuately bending inward to the fossa, well defined beneath the 

 explanate external border of the dorsal plate and external apical 

 lobe, the latter set with quite long fljang hairs. Internal margins 

 of the valves contiguous in basal fifth, genital fissure broadly fusi- 

 form, margins of the valves not closely approximated at apex. In- 

 ferior pudendal membrane visible in basal half of the genital fissure.
