Parthenot virens, Moore, Annals of Nat. Hist. 1877, p. 47. de Niceville, Butt, of India, etc., ii. p. 149

Iji.\go. — Male and female. Upperside with the ground colour uniformly 

 senescent-green. Foreioing witli the two outer cell-marks nearly opaque and greenish- 

 white, the transverse discal semidiaphanous white macular band interrupted, broadly 

 separated by black veins, the portions smaller and shorter than in P. Gambrisi us, the 

 two median spots rounded, the submedian very small and round ; the marginal 

 black bands broad. Hindiviiig with the black basal bands narrower, the inner discal 

 spots prominent, the outer discal duplex-marks shorter and broader, the subraarginal 

 spots broadly conical, and the marginal band broad, these three latter series thus 

 showing narrower interspaces. Underside somewhat darker than in P. Gambri>iii(,s. 

 Forewing with the markings more broadly black-bordered, the marginal bands 

 broader, macular, and black. Hindioing with the markings blacker and more 

 broadly defined. 



E.'^panse, c? 4 to 4^-0, ? 4j^ inches. 



Caterpillar. — Cylindrical. Head and anal segment minutely spined, other 

 segments with minute sublateral spines ; third to twelfth segment each armed with 

 erect subdorsal rather long branched-spines. Colour olive-green, with a sublateral 

 pale yellow band ; head and spines purplish ; feet brownish. (Taken from the 

 original drawing made in Kanara by the late S. N. Ward, and from the published 

 figure by Mr. J. Davidson.) Mr. Ward, in MS. Notes, fully describes the larva, 

 probably taken just previous to pupation, as the colours given differ from his original 

 drawing, which also includes the pupa and imago, as follows : — " August 6th. Larva. 

 Head dull yellow-brown ; back ditto, but more brown ; sides brownish-purple, upper 

 part yellow, middle all through lighter, purple below ; back and sides covered with 

 minute white spots. A ridge of foui'-branched spines purple at top with others 

 below are inserted just along top of the back, those on 3rd, 4th, 10th and 11th 

 segments being longer than the others, those on the 3rd longest of all. A single 

 spine (forked) on the 3rd and 4th segments, and single on rest of the other segments 

 just above the yellow mark, and a line of plain white spines at the bottom of it, four 

 on each joint, of which the 4th is far the longest, and a shorter row just above the 

 feet of which the two middle are longest. The anal segment thickly set with single 

 spines ; head ditto, some black, some white. Feet light brown, except anal, which 

 are black and shining. Changed to pupa August 9th. Imago emerged August 

 12th." 



Chrysalis. — Boat-shaped ; dorsum and thorax arched and somewhat sharply 

 keeled ; wing cases also keeled in front ; head ending in two obtuse points. Colour 

 uniformly brown. Suspended perpendicularly. *
