It is very curions tliat in tliis sppcics and several others the variation in 

 size is considerable, and especially that the intermediate sizes seem to be rarer 

 than the more extreme individnals. We have here cases of imperfect dimorphism. 

 The name of burmanica is based on a very small specimen.

<??. End-segment of antenna h)nger than tha three preceding segments 

 together, in colonr similar to a//ici/tia, forewiug nearly as in yi/i-ans ; essentially 

 different from both in the abdomen being marked 'fiMh.four pale cadmium-yellow 

 side-jiatches which are separated from one another by brownish black basal 

 patches ; the second and third patch the largest ; seventh tergite as in a/fictitia, 

 without the extended white base of qt/rans ; abdomen below and wings rather more 

 tawny than in affictitia, the former with vc^stiges of pale mesial patches, side-tuft 

 (if fourth segment huffish, not white. 



Wings, abore. Forewing : lines not pnnninent, two anteraedian ones almost 



straight, first two discal ones much less curved than in gi/rans. Hindwing riisset- 



mummy-brown at base, an ill-defined distal border of the same colour, middle of 

 wing paler, especially between apex of cell and anal angle, where there is generally 

 a distinctly yellow shade if the long yellow hair-scales are not rubbed away ; in 

 fresh specimens the whole median area is covered with such yellow hair-scales. 



I'tiflerside : basal area of forewing, especially at costal vein, shaded with 

 yellow hair-scales : abdominal area of hindwing more extended yellow_ tlian in

 black distally, narrow, sides jjarallel, end rounded, somewhat incrassate. ( 'lasper

 (PI. L. f. 34). Process of penis-sheath (PI. LVI. f. 19) ending in a long point, 

 distal edge with a few teeth in middle, ]iroximaI edge dentate at least in basal
