faintly sinuated. The alulse have the tip bhickish and the fringe 

 mostly ])a\e. The abdomen in the male of six segments, behind 

 compressed, the small hypopygium withont any long appendages ;

 bristle outside, the posterior femora one at least in front near 

 the tip ; the fore tibire have scarcely more than a single spine or 

 bristle outside, but often appear minutely pectinated in the 

 apical half, one outside row of the pubescence being lengthened 

 there, which is particularly observable in species 21-23 ; the hind 

 metatarsus is nearly the same length as the following joint, and
