of silky web by the last see'ment to the underside of a leaf of the food- 

 plant, and is girt about the middle with another web. The double 

 dorsal line in the larva becomes rather more bluish before the insect 

 changes." 



Six empty pupa-cases, Mr. Dudgeon informs me, have recently been 

 found by him on the food-plant, all attached to the under surface, with 

 the head of the pupa turned towards the apex of the leaf. All were 

 found at 2,000 feet elevation in the Darjiling district, where the butterfly 

 swarms. Another butterfly of the subfamily Nemeohiincs, Bodona ado- 

 nira, Hewitson, probably feeds on Mcesa chisia of Don in Darjiling, a 

 pupa having once been found by Mr. A. V. Knyvett on that bush (also 

 one of the plants on which Z. flegijas feeds), " attached to the leaf in 

 exactly the same way as is Z. flegijas, i. e., by the tail and with a median 

 silken girth." 



I append a full description of the pupa of Z. flegyas obtained at 

 Badamtam near Darjiling, 3,400 feet elevation above the sea, by Mr. 

 Dudgeon. 



Pupa, '55 to '70 of an inch long.* Shape fusiform, broadest in the 

 middle, tapering towards both ends, with the anterior end truncate- 

 rounded, distinctly broader than the posterior ; the whole pupa extra- 

 ordinarily flattened, and consequently of very slight depth even in the 

 thickest part ; the divisions between the segments well-marked ; the 

 posterior segment bluntly rounded ; the head also rounded, divided in the 

 middle line at the apex into two lobes by a shallow notch, the sides of 

 which are parallel to one another and at right angles to the bottom ; 

 colours light bright yellowish-green throughout, above marked with rich 

 emerald-green narrow lines arranged in an arabesque-like pattern on 

 the two outer thirds, a sei-ies of round spots along the middle of the 

 back on the abdomen only, and a subdorsal line on either side interrupt- 

 ed at the segmental constrictions. The under surface is pale yellowish- 

 green throughout, entii'ely unmarked. Owing to the extremely depressed 

 form of the pupa, the wing-cases are almost entirely invisible fi'om 

 above ; they show only by a very narrow emerald-green line on each side 

 of the thorax and two anterior abdominal segments. The whole surface 

 of the pupa is entirely smooth, without any hairs or shagreening whatever. 

 Owing to its beautiful coloration and curious markings this pupa is one 

 of the prettiest I have seen, and far surpasses anything known to me in 

 the family Lyccenidcs.
