BEVISION OF ELEODIINI BLAlSDELL. 183 



The tibial grooves of the femora are well defined and concave, 

 glabrous and impunctate and prolonged inwardly upon the femora; 

 their margins are subcarinate. External borders of the tibite punc- 

 tate and pubescent and not in the least carinate. 



The tarsi are slender and api^arently slightly compressed. 



A protarsus is about one-third of its length shorter than a meso- 

 tarsus; joints small, the first distinctly larger and longer than the 

 second, the latter about as long as W'ide; the third just slightly 

 shorter, and the fourth still smaller, both slightly wid^r than long. 

 In the female the first joint is less robust. 



The mesotarsi are about one-fourth of their length shorter than a 

 metatarsus; the first joint of each is about as long as the third and 

 fourth taken together; the second a little longer than wide, and the 

 third and fourth about as wide as long, each gradually and slightly 

 decreasing in size and length in the order mentioned. 



The metatarsi are about one-fifth of their length shorter than their 

 metatibia^; first joint of each is just slightly longer than the next 

 two taken together, the second distinctly longer than the third, the 

 latter a little more than half as long as the fourth. 



Subgenus ELEODES Eschscholtz. 



In the present subgenus the species have the anterior femora more 

 or less dentate in one or both sexes; the teeth are abortive in caudifera 

 and longipilosa. 



The anterior tarsi of both sexes are simply spinous beneath, or at 

 the most the first joint may bear a small tuft of modified spinules in 

 one or both sexes, and the first one or two joints are never dilated in 

 the male, although in a few species the first joint may be thickened 

 at apex beneath. 



Thie internal spurs of the meso- and metatibise are longer than the 

 external. 



For the positive recognition of the constituents of this subgenus 

 the female genital characters must be relied upon. 



The male genitalia have undergone but little ditferentiation along 

 the lines of specific specialization and are valueless for the diagnosis 

 of species. 



They may be enumerated as follows : 



Sithgcneric genital churaeters^ male. — Apicale of the edeagophore 

 distinctly longer than wnde; dorsal surface moderately convex, with 

 a more or less complete membranous median groove, which at times 

 is strongly developed, at others feebly so; apex acute and not dis- 

 tinctly attenuated ; base distinctly lobed at the middle. 



Female. — Genital segment more or less trapezoidal in outline and 

 robust, conspicuously setose in apical moiety with evident tufts of
