Wings brownish grey, rather thickly covered with black hairs ^ 

 and with a fringe of long black hairs around the whole border 

 except at the tip of the wing, where, for the distance between the 

 lower branch of the second longitudinal vein and the upper branch 

 of the fourth, the black hairs are replaced by long, snow-white 

 bristly hairs. Five spots 011 the wing-border (each consisting of a 

 few silvery white scales, which have a faint bluish tint) are placed 

 as follows : a larger one in the centre of the fore border, the second 

 (a small one) just beyond the first ; the third at the end of the lower 

 branch of the fourth longitudinal vein ; and the fourth and fifth at 

 the tips of the sixth and seventh longitudinal veins, the fourth 

 spot being the largest. 



Described from a perfect unique $ in the Indian Museum 

 collection captured by Dr. Annandale at Kurseong, 5-vii-o8.

Body : Ground colour of thorax blackish brown, of abdomen, 

 blackish, both covered with thick, long, pale yellowish grey 

 bristly hair, plentifully intermixed on the thorax with black hairs, 

 and likewise, to a less degree, on the base of the abdomen. The 

 hairs on the thoracic dorsum show a tendency to be arranged in 

 fan-shaped sets. On the abdomen they are arranged in a thick 

 row of long ones on the posterior border of every segment, with a 

 shorter, erect row in front of them. Pleurse light to dark 

 mahogan}^ brown, bare, or nearly so. Byes bronze, with large 

 facets. The antennee have the two large basal joints (second one 

 cylindrical, wider than the first, which is cup-shaped) covered with 

 short white scales, and are surrounded by a cluster of longer ones ; 

 flagellum of thirteen small globular joints of equal size, last one 

 conical, each with a circlet of a few long black hairs, and more 

 numerous, short white ones. 



Legs : Femora and tibiae grey, with minute greyish white 

 pubescence, a number of longer, white bristly hairs (with black 

 reflections in certain lights). These are apparently irregularly 

 placed on the fore legs and the femora, but show a tendency 

 to form longitudinal rows. Those, at least on the hind tibiae are 

 arranged in three such longitudinal rov/s, one pointing outwards, 

 the other two rows, posteriorly. The apical part of the tibiae is 

 narrowly but thickly clothed with jet-black scaly bristles, and the 

 extreme tip with a circlet of white scaly bristles. The tarsi are 

 thickly covered with jet-black scaly bristles, the tips of the meta- 

 tarsus and following joint bearing a circlet of white scaly bristles. 

 The metatarsus bears several very strong long black bristles, and 

 the extreme tarsi tips have minute cream-coloured scales. 



Wings : Dark grey, with all the veins bearing a double row of 

 spreading hairs, and without scales. Upper fork of second 

 longitudinal vein bifurcates at two-fifths of the wing, and the
