hairs ; each of the areas mentioned above has three to four distinct 

 rows of bristles arising from black rounded spots. A few bristles also 

 arise from the dorso-pleural suture. Scutelluni whitish except for a 

 black band in the middle. Postscutellum with alternating bands of 

 grey and brown in a longitudinal direction. Laterally the thorax is 

 dark brown except at the sutures, which are light yellow. 



Wing (fig. 2) 2-7 the length of thorax, base to subcostal junction -61, 

 anterior forked cell -23, posterior forked cell -15 of the whole wing. Wing 

 veins densely covered with spatulate scales. Costa dark-scaled all along 

 except at the base near the junction of the humeral cross- vein, where 

 there is a yellow-scaled spot involving the base of the first longitudinal 

 also. The second yellow spot is a large one at the apex of the wing 

 opposite the termination of the first longitudinal and extending more 

 than half the length of the anterior forked cell. All the veins clothed 

 with dark yellow scales except for the following five patches of black 

 scales : (1) at the base of the second longitudinal vein, (2) at the 

 forking of the second longitudinal vein, (3) at the base of the third longi- 

 tudinal and at the same position on the second and fourth longitudinal 

 veins, covering the cross- veins as well, (4) at the origin of the fourth 

 longitudinal vein and (5) at the forking of the fourth longitudinal vein. 

 The wing-fringe is of a darkish hue with jet black j)atches at the tij)s of 

 the posterior branch of the second longitudinal and the anterior branch 

 of the fourth longitudinal veins ; between these two dark patches the 

 fringe is of a yellow colour. The arrangement of large and small 

 scales m the fringe is quite normal. 



Halferes with the capitellum of a dark brown colour, the scape and 

 scabellum being yellowish. 



Coxae scaleless, of a creamy colour with a few hairs ; trochanters also 

 with a few hairs and of the same colour as coxae. Fore legs uniformly 

 brown except for the white spots at the femoro-tibial and the tibio- 

 tarsal joints. The femur of the middle legs has a three-coloured band 

 owing to the arrangement of the scales ; it is formed of white scales 

 in the middle, black above and brownish at the tip of the femur. In the 

 hind legs the femur (fig. 3) has, just below the middle, a large tuft of 

 black scales surrounding it entirely ; below this tuft there is a very pro- 

 minent tuft of snow-white scales reaching to the knee-joint, the condition 

 appears to be simply a much more exaggerated one than that found in 

 the femur of the mid-legs, except that the brown band at the tip of the 

 femora of the middle pair of legs is absent. The tibial and tarsal 

 portions of the mid and hind pairs of legs are uniformly brown except 

 for a whitish band at the tibio-tarsal joints. Ungues simple. 



Abdomen dark brown, without any scales except a few black ones 

 on the last segment and on the genitalia ; it is covered by a large 

 number of golden yellow bristles. 



The structure and form of the egg is not known. 



The Larva (fig. 4.) 



The head is of a dark brownish colour with three pairs of branched 

 hairs on its dorsal surface. The clypeal hairs are rather small, the inner
