yellow bristles beneath ; all the femora about the base with a whitish 

 yellow pubescence (especially on the under side) which usually merges 

 into the black one and which sometimes disappears, and on the post- 

 erior tibiae there is a few paler pubescence about the base, though 

 sometimes disappeared; apical joint of all the tarsi bearing a fringe of 

 somewhat long blackish bristly hairs about the upper apical margin. 

 Pulvilli dull orange yellow ; claws obscurely brownished red at the base 

 but black at the tip. 



Abdomen broader than the thorax, and very slightly longer 

 than the head and thorax (including the scutellum) together, flattened 

 and the tip not pointed but roundly convex, black. Dorsum moderate- 

 ly shining but slightly dusted with brownish, the posterior margin of 

 each segment very narrowly but distinctly tinged with yellow but obscured 

 by a dense ashy grey tomentum, with three interrupted ashy grey 

 dorsal stripes composed of triangular spots, which are usually incon- 

 spicuous on the apical three segment and can easily denude especially 

 on the posterior segments ; these spots not continued with the preced- 

 ing spot or following one, but the three spots on the same 

 segment connected with each other by a narrow ashy grey hind 

 marginal band ; the sides very narrowly tinged with yellowish 

 brown, but not covered with a ashy grey dust ; pubescence on the disc 

 sloping, rather numerous and black, but on the ashy grey spots and on 

 the same coloured posterior marginal bands mostly greyish white ; on 

 the sides there are rather numerous outspread black hairs, which about 

 the insides of the lateral margins are intermixed with a rather con- 

 spicuous yellowish white pubescence, especially on the second and third 

 segments. Ventre black, moderately dusted with grey, with narrow 

 yellowish grey hind marginal bands except on the basal segment cloth- 

 ed with fine sloping yellowish pubescence with longer less sloping black 

 bristly hairs intermixed ; the black hairs become more conspicuous to- 

 wards the tip, and on the seventh segment much more bristly and 

 almost erect.
