Legs of males moderately crassate; dorsal surface of second .joint 

 scarce!}^ inflated. 



Anterior male legs to the sixth provided with a rather small fleshy 

 sole. 



Coxaj of second male legs with a slight rounded prominence in the 

 mesial face of which is located a seminal opening. 



Copulatory legs subcompressed at base, scarcely trigonal, and with a 

 uodiform jirojection on the anterior side; the hairy portion is separated 

 from the ungual by a distinct constriction or notch, as viewed from the 

 side; the ungual portion is very short, less than half the othei' and 

 bears three spiniform processes; the proximal is slender and turns 

 mesad and distad, crossing its fellow; the other two are subequal in 

 size and length; the posterior (ventral) turns mesad and then ventrad 

 (cephalad) ; the other is directed cephalad and bears several slender 

 spiniform teeth, which are directed mesad from its mesial margin. 



HARMODESMUS NITENS Cook. 

 (Plate LV, tigs, la, 1?;.) 

 Harmodesmus nitens Cook, Proc. U. S. Nat. Mus., 1895, XVIII, p. 83. 



Vertex smooth and shining, evenly convex, without hairs; the sulcus 

 slight, the suture distinct. 



Clypeus without hairs; a pair of minute setiferous punctations 

 between the antennal sockets and about as far from each other as from 

 the sockets; somewhat below these is another pair of punctations 

 wider apart; lateral edges of clypeus straight, the inferior corners 

 rather square; labral emargination slight. 



AnteniKc rather sparsely hirsute with short hairs.- 



First segment with the carinju tilted somewhat horizontally, the ante- 

 rior side somew'hat downward; the raised anterior margin extends to 

 the height of the antenniii; the posterior is somewhat shorter; the 

 lateral part thus margined is distinctly rugulose. 



Segments dorsally smooth and shining, the cariuic distinctly rugulose; 

 the posterior subsegments are somewhat more convex than is usual, so 

 that, viewed from the side, the body appears slightly moniliform. 



Lateral carinne with distinct raised margins in front and behind, the 

 calli with their mesial edge distinct and longitudinal; lateral margins 

 rounded, the corners obsolete on anterior segments, the i)osterior corner 

 gradually more prominent, produced only on posterior segments. 



Repugnatorial pores facing dorsolaterad, located in distinct excava- 

 tions of the marginal callus, which is much broader on poriferous seg- 

 ments. 



Anterior subsegments smooth on their anterior part, longitudinally 

 rugulose on the posterior half; transverse sulcus very narrow and dis- 

 tinct, scarcely crenulate; supplementary margin very short. 



Penultimate segment short, exposed portion equal to about one-third
