Legs of male sparsely hirsute, except the anterior, of which the ven-

Male genitalia, see Plate TiVII, figs, la-lc. 



Color of alcoholic specimen grayish brown, the posterior margin of 

 each segment, the carinas, antenna^, and legs, yellowish brown.

OMODESMUS, new genus. 



Body rather large, about five times as long as broad, oblong, taper- 

 ing slightly at both ends; dorsum slightly convex and the carinse 

 more nearly horizontal than elsewhere in the present family. 



Antennii; (?). 



First segment slightly less than three times as broad as long; pos- 

 terior margin nearly straight, the lateral parts only slightly curved 

 forward. 



Segihents show faint traces of three transverse rows of small 

 granules. 



Lateral carinse with lateral thickened margins well developed and 

 distinctly continued upon the anterior and posterior edges of the 

 carina*; on anterior segments the lateral margins are strongly thick- 

 ened and very broad; the posterior corner of these segments is also 

 strongly thickened, so that the broad margins are not distinct mesad. 

 Corners of all carin.c more prominent and produced caudad than in 

 other known genera of the family. 



llepugnatorial pores 13. 



Preanal scale minutely apiculate; setiferous tubercles distinct, close 

 together. » 



Sterna with a distinct, transverse, medianly interrupted ridge 

 between the bases of eacii pair of legs. 



Sternum of sixth segment of male witli an oblong, strongly apiculate 

 process between the bases of the anterior ])air of legs. 



Sternum of fifteenth segment of males with a broadly ensiform i)rocess 

 projecting cephalad from between the anterior pair of legs into a socket 

 in the posterior part of the fourteenth. 



Legs of males rather slender, scarcely crassate; dorsal face of sec- 

 ond joint inflated into a large, rounded prominence; anterior six male 

 legs M'ith a small fleshy sole at the apex of the last joint below. 



Coxa^ of second male legs produced ventrad into an obliquely conic 

 process with the seminal opening located in a slight depression of its 

 ventro])Osterior face. 



Male genitalia with second joint proximally hirsute and trigonal, 

 the ungual portion proximally strongly compressed and strongly 

 curved cephalad upon itself; it is .then expanded into a large, irregu-
