“Wing is much spotted, costa has six dark spots and sub¬ 
costal t^vo. The first longitudinal has six spots, the central 
spot being divided into three. The second vein has two dark

spots. The fourth vein has two spots on the main stems, with 
two on the upper and two on the lower branch. The fifth vein 
has two on the main stem, with two, often three on upper, and 
two on the lower branch. The sixth long vein has three dark 
spots. The fringe is dark with light areas opposite the termina¬ 
tions of the veins and their branches. 
Legs are black with many white spots ; hind leg has 2J-2J 
white tarsi; the first tarsus has its lower third covered with 
white scales, the remainder is black. The metatarsus has a 
distinct white band at its lower end, this band is most constant, 
the remainder is speckled. The tibia is spotted and has a 
distinct black band at its lower end. The femur is black with 
many white spots. Mid-leg, all the tarsi are black, the joints 
are white, metatarsus, tibia and femur black with many white 
spots. Fore-leg, the two lowest tarsi are black, the second has 
a well marked and constant white band, the first also has a pale 
band at its distal end. 
J . There are many broad upright forked scales on the 
head, otherwise the cephalic ornamentation is the same as in the 
female. Palpi have three, often four white bands, the basal, 
the smallest is often very indistinct, the central is longer, and 
the apical the same as in the female, is often divided into two. 
There are not complete bands as in the female; antennae have 
marked club-shaped ends, which are covered with dark bristles.
