 rings just after the base, of the fore tibiae, at the knees of the middle 

 legs, at two-fifth and four-fifth of the middle tibiae, on the basal two- 

 third of the first joint of two posterior tarsi, and on similar parts of 

 the hind legs only more narrowly at the knees ; the middle dark ring 

 on the two posterior tibiae more or less brown and not very well- 

 defined ; the basal dark ring on the same almost always much more 

 paler than the middle one and more inconspicuous ; all the femora 

 obscured by a dense grey tomentum except for the knees quite bare 

 from dust, the pubescence on the front one long and mainly blackish, 

 on the middle femora nearly all yellow but black about the tip, and 

 on the hind femora antero-ventrally long and almost all yellowish but 

 denser and shorter all about the tip, and a small fringe of somewhat 

 bristle-like and black hairs on the ventral margin of the apex of hind 

 femora; front coxae long and strong, much greyer than the femora, 

 and bearing long pubescence which is whitish on more than the basal 

 half but black afterwards and shorter on the outside ; posterior coxae 

 short and greyish, and bearing rather long mainly whitish pubescence ; 

 front tibiae covered with a short and black pubescence though there 

 are pale hairs on the orange part, and with a very few touch-hairs ; 

 middle tibiae with numerous scattered long blackish hairs, and some 

 shorter pale .j hairs on the typical bands, and bearing two unequal black- 

 ish spurs ; hind tibiae with a long conspicuous rather dense black- 

 dorsal fringe, and with a long finer but almost equally dense ventral 

 fringe, but with rather numerous yellowish hairs almost all over especi- 

 ally on the pale bands ; all the tarsi with numerous conspicuous black 

 pubescence and with a few long curved pale hairs at the apical upper 

 margin of the terminal joint, and bearing blackish claws and yellowish 

 brown-grey pulvilli.
