group of the greyish white at the nape, on the shoulders, near 

 the wing joints, and around the "bare space" almost forming 

 a submedian line on either side, on some specimens a faint 

 ill defined submedian light spot on either side, brown bristles 

 mostly confined to the lateral margins. The yellowish scales 

 are scattered through the brown ones on the middle portions 

 of the mesonotum ; scutellum dark, covered with the greyish 

 white scales and heavy dark brown bristles grouped on the 

 margins of each lobe ; metanotum light brown, nude with a 

 dark median line ; pleura brown, heavily clothed with white 

 long flat scales and long light hairs. 



Abdomen dark, covered with very dark brown almost black 

 scales, and narrow white bands which on the third and fol- 

 lowing segments broaden so as to form basal white lateral 

 spots. A few white scales are scattered throughout the brown 

 ones on some segments. The first segment has two sub- 

 median white spots and many light hairs, the second segment 

 has a median narrow light line extending from the base to the 

 distal margin, the following segments have narrow basal white 

 bands not always complete, and widened to form the lateral 

 spots, the eighth segment largely, in some specimens entirely, 

 white scaled ; venter light scaled, the membrane showing 

 through somewhat darker in some specimens. 



Legs : coxje light brown, rather heavily clothed with white 

 scales and line long hairs ; trochanters with some brown scales ; 

 femora covered with dark brown and white scales intermixed, 

 the ventral aspect lighter almost to the apex, more marked on 

 the hind legs, of which the ventral aspect is almost white, a 

 tiny light knee spot ; tibi?e also with dark and light scales inter- 

 mingled, a ventral light line and very narrowly light at the 

 apex ; the first tarsal joint on the fore legs, darker, a minute 

 basal light spot and a line of white scales that reaches nearly 

 to the apex, which is dark, second and third tarsal joints have 

 small basal light bands, reduced to a mere dot on the fourth, 

 and the fifth is wholly dark. On the mid-legs the first tarsal 

 joint shows a very narrow light line, not extending the whole 

 length of the joint, the second, third, and fourth tarsals basally
