2. Palpi scaled and with four white bands; the three outer bands 
are broad and equal, the innermost band is narrow; tips of the palpi 
white. 
Proboscis brown with lighter tip. 
Head with broad white forked scales in front and dark ones behind ; 
with a scanty tuft of long white hairs projecting forwards. 
Antennae brown with white hairs. 
Thorax chiefly covered with white 
hairs, but also with a few short spindle- 
shaped creamy scales. Dark longitudinal 
lines and two dark eye-like spots can be 
made out on the dorsum of the thorax. 
Halteres with the knobs covered with 
creamy white scales. 
Abdomen black, thickly covered with 
golden hairs but without scales. 
Wing veins covered with rather broad 
scales (fig. 28), forming numerous black 
and white spots arranged as follows 
(fig. 29): 
The costa shows four large black- 
scaled areas and three small ones; the 
first longitudinal vein shows seven dark- 
scaled areas of different sizes arranged 
as shown in the diagram; the main 
stem of the second longitudinal vein has 
two black-scaled areas, the anterior 
branch has five very small spots and 
the posterior four; the third longitudinal 
vein has two large black areas; the 
fourth longitudinal vein has three dark 
spots on its main stem and generally 
SS ee three on each of its branches; the fifth 
__ LS longitudinal vein has three dark spots 
on its main stem and one at its bifur- 
/ cation, its anterior branch has five dark 
areas and its posterior three; the sixth 
Fig. 28. longitudinal vein has four dark areas. 
Wing seelceiad Se pane The number of dark and light scaled 
areas on some of the veins is not con- 
stant, however, and two or three of the small spots may sometimes be 
joined together so as to form one long dark scaled area. 
The wing fringe is interrupted by a light scaled area at the termina- 
tion of each of the longitudinal veins. 
The legs are speckled with white scales on a brown ground; in the 
fore legs the fifth tarsal segment has a few white scales at its tip and 
there are apical white scales which extend over the joint so as to form a
