EEVISION OF ELEODIINI BLAISDELL. 97 



Legs moderate in length, comparatively somewhat slender. Femora 

 miitic and not thickened ; anterior tibial spurs dissimilar in tli,e sexes ; 

 anterior tarsi with the first joint slightly thickened at tip beneath, 

 groove interrupted at the ventral apical margin, tuft of spinules 

 feebly developed and slightly dissimilar in the sexes. 



Male. — Oblong-ovate to ovate, not slender. Antennfip reaching a 

 short distance beyond the j^rothoracic base. Abdomen feebly oblique, 

 moderately convex, more or less impressed at middle on segments one 

 and two. Anterior spurs of the anterior tibia' usually about 

 three times longer than the posterior, slightly broadened and slender, 

 acute, gradually narrowing from base to apex. 



Female. — Ovate, robust. Antenna' reaching at least to the protho- 

 racic base. Elytra arcuately and vertically declivous behind. Abdo- 

 men horizontal, strongly convex. Anterior spurs of the anterior 

 tibia? much broadened and produced, about three times as long as the 

 posterior, sides subparallel and narrowed in apical fourth, subacute, 

 W'Orn spurs are obtusely rounded at tip. 



In the material before me three forms may be recognized : 



Forma typica. — Elytra generally flattened on the dorsum, sides of 

 the disc are not broadly rounded, and the inflexed portions are ob- 

 liquely and inwardly declivous. Elytral disc very densely and rather 

 finely muricately punctate. 



Forma granulato-muricata. — Elytra generally moderately convex 

 on the dorsum, sides more or less broadly rounded, disc moderately 

 densely granulato-muricate, granules fine and shining. 



Forma tuberculo-muricata. — Pronotum more arcuately declivous 

 laterally, with the margins more or less invisible from above. Elytra 

 more coarsel}^ and strongly sculptured, subtuberculately muricate, the 

 punctures much sparser than in the typical form. 



Measurements. — Males: Length, 14.2-17.5 mm.; width, 0.2-7 mm. 

 FeTnales: Length, lG-20.2 mm.; width, 7.6-8.5 mm. 



Genital eharacters, male. — Edeagophore elongately ovate, pointed 

 and slightly arched, 



Basale oblong, evenly convex above ; sides feebly arcuate. 



Apicale triangidar, twice as long as wide, evenly convex above, 

 with a rather wide median membranous groove in apical half; sides 

 straight and convergent to the subacute tip; base with a rounded lobe 

 at middle, feebly sinuate laterally. 



Sternite subparabolic, almost as wide as long. Each lobe with the 

 outer border more or less straight in basal two-thirds, thence obliquely 

 subtruncate to apex, tip narrowly rounded; internal margin feebly 

 arcuate; surface scarcely convex, glabrous, very sparselv punctate in 

 apical half and setose, seta' moderately long, longer on apical margin 

 and rather sparse. Membrane wath scattered seta? across the bottom 

 of the sinus, the latter quite deep.
