EEVISION OF ELEODTINI BLAISDELL. 455 



Elytra elongate oval, fully twice as long as wide ; haae subtruncate, 

 feebly sinuate laterally; humeral angles more or less distinct; inarghi 

 acute, not foliaceous nor suddenly formed, evenly and gradually 

 reflexed and attaining the apex; sides feebly arcuate, gradually nar- 

 rowing to apex and attenuately converging, apex acute and not pro- 

 duced ; disc more or less concave, suture frequently raised posteriori}' ; 

 here the disc is more or less biconcave, gradually, evenh' arcuately 

 declivous behind, acutely inflexed laterally, the inflexed sides moder- 

 ately oblique and plane; surface sculptured with fine, irregularly, 

 sparsely, and evenly placed, subasperate punctures, the inflexed sides 

 similarly sculptured; each puncture bears a very minute decurved 

 seta. 



Epipleunv narrow, scarcely at all differentiated from the inflexed 

 sides of the elytra and similarly punctured; distinctly defined at apex 

 and feebly, minutely dilated beneath the elytral apices. 



Sterna opaque and finely, irregularly sculptured. 



Parapleiiroi opaque and obsoletely punctate. 



Abdomen opaque, finely, rather evenly and not densely punctulate; 

 first two segments horizontal, third slightly oblique, last two nuich 

 less convex. 



Legs long and rather slender; posterior femora usually as long as 

 the first four abdominal segments; profemora mutic; tibial spurs 

 quite similar and the protarsi simple. 



Male. — Elongate and rather narrow. Abdomen quite strongly 

 convex, median surface of the first three segments more or less broadly 

 and feebly impressed. Anterior tibia^ suddenly and briefly con- 

 stricted at base. 



Measurements. — Males: Length, 15-20 mm.; width, 6-8 mm. 



Genitcd characters^ male. — Edeagophore elongately subfusiform, six 

 to eight times longer than Avide, more or less arched. 



Basale elongate, about five times longer than wide; sides sub- 

 parallel to slightly arcuate; surface transversely and moderately 

 convex, distinctly membranous centrally at the distal extremity. 



Apicale rather slender, elongately triangular ; dorsal surface moder- 

 ately convex, with a median linear groove at middle two-thirds, very 

 sparsely and finely punctulate: sides briefly arcuate at base and 

 middle, wuth intervening edge and side of apex feebly sinuate; apex 

 subacute and slightly produced ; base distinctly bisinuate with a 

 median subacute lobe. 



Sternite subparabolic in outline, circularly concave at middle like 

 a watch-glass between the bases of the lobes. Each lobe triangular 

 and distinctly longer than wide; external l)order evenly arcuate.^ 

 apex subobtusely rounded, and the internal border straight or feebly 

 sinuate; surface more or less convex, concave internally to sinus, 

 basal third smooth and almost impunctate, apical two-thirds densely
