EEVISION OF ELEODIINT BLAISDELL. Ill 



^lightly dissimilar in the sexes, first joint of the anterior tarsi slightly 

 })rodnced at tip beneath. 



Male. — Oblong-, somewhat elongate and moderately narrow, anten- 

 na' reaching to the prothoracic base. Elytra moderately and gradu- 

 ally narrowed in apical third ; abdomen slightly oblique, moderately 

 convex from side to side, broadly and indefinite^ flattened along the 

 middle ; intercoxal process more or less concave. Anterior spur of the 

 anterior tibia about a third longer tlian the posterior, scarcely curved 

 and moderately thickened, gradually narrowing from base to apex, 

 the latter acute. First joint of the anterior tarsi with a small but 

 definite tuft of silken pubescence on the thickened tip beneath. Sec- 

 ond joint simple. 



/^ema^e.— Oblong-oval, robust. Antennae reaching to the posterior 

 fifth of the i:)roth()rax. P^lytra broadly oval and arcuately narrowing 

 in ajjical fourth. Abdomen horizontal, strongly convex and not 

 impressed. Anterior spur of the anterior tibia slightly more than 

 one-third longer than the posterior, curved, distinctly broadened, sides 

 subparallel and rather suddenly narrowed at apex. First joint of the 

 anterior tarsi with a tuft of piceous spinules upon the produced tip 

 beneath. * 



Two forms may be recognized : 



Forma typica. — Glabrous and not pubescent. 



Forma asperata. (LeConte.) — Subscabrous. Antenna? scarcely 

 reaching to the base of the prothorax; sides of the elytra at apex 

 decidedly muricate to subspiculate. Legs sparsely clothed with pale, 

 flavate, recumbent hairs. 



Measurements. — Males: Length, 19.5-i2G mm.; width, G.5-10 mm. 

 Females: Length, 19-27 mm.; width, 8.5-12 mm. 



Genital eharaeters, male. — Edeagophore more or less elongately 

 fusiform and feebly arched. 



Basale more or less elongately suboval, strongly convex and more 

 cr less gibbous in basal half, smooth and shining; sides evenly arcu- 

 ate and converging slightly from apex to base. 



Apicale triangular, slightly elongate, evenly convex above with a 

 rather broad median membranous groove in apical half; sides feebly 

 arcuate to feebly subsinuate in apical half; apex subacute and very 

 narrowly rounded; base feebly and broadly lobed at middle and 

 feebl}' sinuate laterally. 



Stern ite more or less parabolic in outline, about as long as wide. 

 Each lobe wdth the external margin more or less evenly arcuate, 

 sometimes scarcely subangulate at middle; apex subacute to nar- 

 rowly rounded; internal margin more or less arcuate; surface feebly 

 convex, shining and glabrous, quite regularly and not densely' 

 punctate, setose, setse, moderate in length and slightly longer in apical
