faintly sinuated. The alulae have the tip. blackish and the fringe 

 mostly pale. The abdomen in the male of six segments, behind 

 compressed, the small hypopygium without any long appendages ; 

 in the female of five segments, depressed, conical ; the anterior 

 segments with the hind margin ciliated towards the sides. The 

 hind coxae, and sometimes the middle pair also, have a black 

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

 the tip ; the fore tibiae 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 

 is usually armed in some peculiar way beneath in the male, except 

 species 22.

Dull brassy, not shining. Antennae of the male scarcely half as long- 

 as the thorax ; arista as long as the antennae. The tip of the femora,
