EEVISION OF ELEODIINT BLAISDELL. 301 



obsoletely margined; sides moderately arcuate from base to apex, 

 finely margined, the margin frequently more or less narrowly re- 

 flexed ; base moderately arcuate and rather coarsely margined, about 

 one-third wider than the apex and distinctly greater than the length; 

 apical angles distinct and more or less prominent anteriorly, gener- 

 all}^ acute and not dentiform; basal angles distinctly rounded, fre- 

 quently subobtuse. 



Propleura' sparsely punctate and more or less rugulose, frequently 

 smooth externally. 



Elytra broadly oval and usually strongly inflated, always less 

 than twice as long as wide, widest at the middle; base moderately 

 emarginate, usually as wide as the contiguous j^rothoracic base; 

 humeri obtuse, not prominent nor rounded; sides evenly and quite 

 strongly arcuate, apex more or less produced; disc quite evenly and 

 strongly convex from side to side, at times more or less feebly de- 

 pressed on the dorsum, and more strongly rounded laterally, evenly 

 and arcuately declivous posteriorly ; surface punctate and feebly sul- 

 cate, punctures more or less coarse and arranged in moderately dis- 

 tant series, intervals at times feebly convex^ at others flat, with a 

 single series of fine punctures, which are more or less regularly or 

 irregularly arranged; laterally and on the apex the punctures be- 

 come much coarser and the intervals at times strongly convex. 



Ej)ij)leur<:v moderately narrow at base and very gradually narrow- 

 ing to apex, superior margin near base broadly and feebly sinuate; 

 surface smooth, very finely and distinctly or obsoletely, sparsely 

 punctate. 



Sterna more or less shining, moderately densely punctured and 

 rugose. 



Parapleural more or less coarsely punctate. 



Abdomen, horizontal, moderately convex, shining, and glabrous, 

 very sparsely punctulate and more or less rugulose. 



Legs rather long and moderate in thickness. Anterior femora 

 armed in one sex. Anterior tibial spurs similar in the sexes, the 

 anterior slightly longer than the posterior, both acute. Tarsi nearly 

 similar in the sexes; each joint, except the last, of all the tarsi with a 

 slender and acute tuft of golden-yellow and somewhat modified 

 spines on apical angles beneath. (See male.) 



3Iale. — Elytra rather gradually and arcuately declivous behind 

 and produced at tip into a moderately long cauda, which is not hori- 

 zontal; elytral sides and dorsum feebly and broadly sinuate before 

 the produced apex, the latter with its inferior surface a part of the 

 general internal elytral surface and narrowly margined at the sides 

 by the epipleurse. Abdomen more or less broadly impressed in the 

 median line on first three segments. xVnterior femora armed with a 

 rather long, acute, and rather strongly curved tooth at outer fourth.
