which is black ; a large white spot, nearly a band, near the apex 
of the femora. Ungues equal and simple. 
Q. Head densely clothed with broad upright forked scales, 
creamy white in front, rich ochraceous behind ; with a dense tuft 
of white hairs projecting forwards ; antennae dark brown, with 
tufts of white scales on the joints, verticillate hairs white; palpi 
densely scaly, covered with brown scales and four prominent 
white rings, the broadest being the apical one. 
Thorax brown to ashy-brown, covered with broad, flat, spindle- 
shaped grey scales, giving it a frosty appearance. Some of these 
scales have a slight ochraceous tinge in some lights, three distinct 
tufts of long and some short white scales projecting forwards 
over the head ; thoracic hairs pale golden ; scutellum brown, with 
similar scales to the mesonotum, and pale golden border-bristles 
may be seen when held in one direction, black when held in 
another; metanotum brown; pleurae densely white scaled. (When 
held in certain lights two dark lines show on the posterior part 
of the mesonotum, due to two dark lines on the denuded surface.) 
Abdomen black, densely clothed with flattish scales, the base of 
each segment nude and thus black, then follows a row of white 
scales, the remainder rich ochraceous ; at the sides of the apical 
end of each segment isa tuft of rather long flat black scales ; 
border-bristles pale ; venter black, with flat white scales. Legs 
with pale bands; fore legs with the femora and tibiae grey 
beneath, with a few brown scales scattered above, metatarsi 
and first two tarsi with broad apical white bands, last two 
tarsi and bases of the others dark brown, ungues equal and 
simple; mid legs much the same, but the femora dark towards 
the apex, with a large white spot near the apex, which is black ; 
apex of tibiae, metatarsi and first two tarsals white, last two 
deep brown, ungues equal and simple. In the hind legs the 
femora and tibiae are much as in the mid, the apex of the meta- 
tarsus is white, and the whole of the tarsi except a narrow black 
band at the base of the first joint ; ungues small, equal and simple. 
Wings (fig. 64) with the veins mostly clothed with pale 
creamy scales, with four large black costal spots and two small 
basal ones, the apical, second and fourth black costal spots 
extend evenly on to the first long vein, the third has a large 
median and a small dark spot at each end ; there are also small 
black spots on the veins as follows :—One at the base of the first 
fork-cell, one at the base and another at the apex of the third 
long vein; two on each branch, and three on the stem of the
