74-90nim. ; the males on the whole being about the same size as th& 

 females. 



The last small spot of the wing-band just below the costa may be entirely 

 wanting ; indeed is generally wanting in the females from North Kanara. 



Lana, 1st Star/e. [vide figs, overleaf). — Shape: swollen in segments- 

 3, 4, 5, thinning off to tail which is only half the width of segment 4. 

 There is a large fleshj^, supraspiracular tubercle on segments 3, 4, 14 

 which is dorsolateral on segment '2 : the one on segment 2 being on 

 front margin, that on segment 14 on hinder margin and the rest in centre- 

 of respective segments. These tubercles are long, conical, covered with 

 little fine spines which are longly bifurcated at ends. There are four 

 bifurcated shafts on front margin of segment 2 ; in a row between the 

 dorsolaterals there is also a row of 4, similar shafts on segment S 

 between the supraspiraculars ; the same on segmeiit 4 : subdorsal and 

 dorsolateral. On segments 4 to 12 there is a subdorsal, circular, ochreous 

 tubercular spot set with o or 6 bifurcated shafts. On segments 5 to 12 

 there is a lateral tubercular spot with a single bifurcated shaft. On each 

 segment 2 to 12 there is a supraspiracular tubercular spot with a short 

 and a long bifurcated shaft and, under each spiracle, a similar spot 

 also with two bifurcated shafts; and on the base of each proleg or in a 

 corresponding region (where there is no proleg) a pair of similar bifurcated 

 shafts. Segment 13 has the same arrangement of spots with shafts as the 

 other segments. The spiracles are very small and black. The head is- 

 round, lightish brown-orange in colour, with a broad, dark band across from 

 eyes to eyes ; eyes are black ; clypeus large, triangular; labrum, antennte 

 and jaws same colour as head, the last with tips dark. Colour of larva is 

 green with the tubercles of segments 2, 3, 4 ochreous, those of segment 14 as 

 well as that segment itself, white; a dorsal, sublateral and lateral brownish 

 longitudinal band the whole length of larva ; belly and prolegs white; true 

 legs transparent white; all bifurcated shafts are black; the shafts of 

 dorsolateral tubercles of segment 14 (tail points) are simple, not bifurcated. 

 Segment 14 is fiat and trapeze-shaped. L : 6mm. ; B : 2mm. in broadest 

 part without shafts. 



2nd Stage. — The bifurcated shafts have all disappeared. The conical 

 tubercles of segments 2 and 14 still exist but are now covered with simple, 

 spinous hairs; the dorsolateral tubercles of segments 3 and 4 are very much 

 shortened and similarly covered with hairs. The whole surface of the body 

 is covered with fine, extremely minute, dark, pointed hairs. The head is 

 round, orange, spotted darker, with the eyes brown. The colour of larva is 

 dark olive-green, with the scars of the tubercular spots of 1st stage light ; 

 anal segment with tubercles thereof white; the subspiracular region whitish ; 

 a spiracular white line from segment o to segment 13 ; dorsolateral tubercles
