is very sparsely covered with very sliort yellowish scales, which 

 probably even iu perfect specimens never wliolly cover the surface; 

 scales at sides of thorax more yellow than orange. Posterior calli 

 ])roininent, ferruginous, covered with irregular siuall black bristles,

 2nd segment (which is the widest) a wide band of scaly yellouish- 

 white pubescence ; the remaining segments also bear similar bands 

 at their bases of more whitish scaly pubescence, this being 

 shortest on the 5th segment ; on the posterior borders of the 1st, 

 Gth, and 7th segments a row of rather strong black bristles, 

 directed backwards. Genital organ distinct, black, encircled 

 towards the posterior part and at the sides by a rather thick 

 fringe of orange hairs ; the tip itself more greyish, and bearing-

 base of the costa, where they are larger and are intermixed with 

 close-lying, dark greyish scales; at the extreme base of the costa 

 is a very powerful, thick, black, curved spine. Teguhe bright
