about equal to the length of the fifth ; first joint just a little longer 

 than wide. 



The metatarsi are about one-half as long as a metatibia; joints 

 two and three subequal in length, a little longer than wide, and 

 together shorter than the fourth; the first about a half longer than 

 wide. 



DENTIPES GROUP, Section B. 



The present section contains those species that have the integu- 

 ments glabrous and more or less shining, and never distinctly as- 

 perately sculptured. The caudal characters, as already defined, show. 

 Avithout doubt, a genetic relationship not heretofore recognized. As 

 in Section A some of the species are ecaudate, but unlike those in that 

 section, there is here no tendency to hirsuteness among its constituent 

 species ; on the other hand there is a tendency to complete non-devel- 

 opment of such epidermal structures; spines and spinules are de- 

 veloped here as in the species of the i)receding Section. 



The anterior tibial spurs are similar in the sexes, acute and mod- 

 erately divergent, at times feebly curved backward. 



The abdomen is horizontal and the intercoxal salient of the first 

 segment is always wider than the metasternal process. 



The genital characters are the same in this section as in the }u-e- 

 ceding one. 



The s])ecies may be tabulated as follows: 



All of the femora armed. 



Femoral teeth strongly developed, long and acute; elytra more or less 



A-ertically declivous behind annata. 



Femoral teeth rudimentary but distinct on the mesofemora and obsolete 



on the metafemora var. impotens. 



Femoral teeth quite equilaterally triangular, shorter, broader, and less 

 acute; elytra evenly and arcuately declivous behind and more attenuate. 



Diilitnrix. 



Femoral teeth smaller and obtuse, otherwise as in militari-s var. fciiionitii. 



Anterior femora alone armed. 



Thorax strongly constricted at base. 



Thorax strongly transverse and very strongly rounded at the sides. 



Disc with sides narrowly impressed and granulate, more or less evenly 

 and moderately convex; elytral apex more or less attenuately pro- 

 duced or caudate acuticauda. 



Disc witli sides l)roadl.v impressed and granulate, less convex ; punc- 

 tuation fin(>]y nuu'icate ; elytra more or less attenuate and not 



caudate var. InticoUis. 



Thoi'ax moderately strongly and evenly rounded at the sides ; elytra not 

 attenuate behind with apex obtusely rounded, never acute nor pro- 

 duced dcntipcs. 



Thorax feebly constricted at base. 



Thorax transverse; elytra striato-punctate, series quite closely placed 

 and impressed, intervals more or less convex suhpinguis.
