REVISION OF ELEODITNI BLAISDELL. 381 



Tliree forms may be recognized according to the character of the 

 sculpturing: 



Forma sublasvis. — Simihir in form to the typical form, but smoother, 

 with the sculpturing somewhat obsolete. 



Forma typica. — Strongly and roughly sculptured ; elytra rugosely 

 punctate, the interstices between the punctures elevated and convex, 

 and more or less confluent transversely. 



Forma intermedia. — Sculpturing more strongly nniricato-tubercu- 

 late, with the intervals between the punctures less convex and conse- 

 quently less rugose, approaching pimelioides. 



Genital characters^ male. — Edeagophore stoutly fusiform, feebly 

 arched. 



^as«?e oblong, about twice as long as wide; surface evenly convex; 

 sides feebly arcuate, and the apex quite deeply and triangularly 

 emarginate. 



Apicale triangular, rather narrow, usually distinctly narrower at 

 base than the basale at apex; surface strongly convex, wnthout 

 groove; sides nearly straight or feebly arcuate, slightly prominent at 

 ; base; apex acute; base acutely lobed at middle, laterally feebly 

 sinuate. 



Sternite subparabolic. Each lobe triangular; external border 

 more or less straight or feebly and broadly sinuate in basal two- 

 thirds, thence quite evenly arcuate to apical margin, angle nar- 

 trowly rounded; internal margin feebly sinuate; surface very feebly 

 convex, punctate and setose in apical half, setae moderate in length, 

 not dense, longer toward and on apical margin. Membrane not 

 setose across the bottom of the sinus, the latter more or less triangular 

 and apparently not closed by the membrane. 

 Female.- — Genital segment triangulo-trapezoidal, surface of the 

 valves sliglitly declivous, setose. 

 Valvula (Plate 4, fig. 6). — Dorsal plate oblong, feebly narrowed 

 from base to apex. Surface plane or feebly concave, smooth, punc- 

 tures scattered, each with a rather long flying seta; borders quite 

 straight ; apical margin oblique, angle obtuse and feebly rounded ; 

 internally not distinctly defined from the apex, the latter rather short 

 and membranous, rounded at tip and clothed with moderately long 

 setse. 



Appendage mammilliform, with a pencil of quite long hairs at 

 tip. Fossa rather large at base of the external apical surface. 



Basal prominences not evident. 



Superior pudendal memhrane longitudinally rugulose, and attain- 

 ing the middle of the dorsal plate. 



Ventrolateral surfaces. — Body triangular, surface lines straight 

 when viewed longitudinally, quite evenly convex laterally, sj^arsely 

 setose in apical half, seta? moderate and more or less flying. Sub-
