THE COMMOy BUTTEltFLlES OF TILE PLAINS OF INDIA. Or,5 



the picture of a catliarine-wheel firework ; the bottoms of all the cells are 

 Huely <:jraniilatG(l and that of the micropyle-snrface is pitted; the whole 

 surface is shiniuj^ like glass iu a strong side-light. The colour is very 

 light bluish-greeuish to the eye ; under the lens all the walls and promi- 

 nences are white and the bottoms of the cells greenish. B: O. 4 mm.; 

 H : O. L> mm. 



Larva.— \% of the typo of Lampido^ Ixtticus ; in shape very like that of 

 Naeadnha atrata ; head light, translucent yellow, eyes black ; hidden 

 under segment '2, round ; body the same breadth from segment 4 to seg- 

 ment 10. and, if anything, getting broader towards the latter segment ; 

 broadest about middle or segment 10, highest in middle — nearly the same 

 height from segment o to segment 10; segment l* is more or less semicir- 

 cular in outline, convex transversely and tumided, with a deep, central, 

 dorsal 4-sided depression at each lateral angle of which is a single 

 hair and tho bottom of which is clothed with minute, sparse, erect, star- 

 hairs and the segment has a depressed, lateral point just above the 

 spiracle and a further longer depression in front of it : the anal segments — 

 11 to 14 — are, together, nearly indistinguishable one from the other, have 

 their dorsal line sloping gently to end, arc more or less flat on top and the 

 surface pitted dented aU over, the extreme end of segment is broad and 

 round ; segment 11 suddenly lower than 10, the latter somewhat tumid 

 at hinder margin : segment 11 has the hinder margin curved convexly for- 

 wards slightly ; segment 1 2 has the hinder margin very strongly curved 

 forward. The surface of the larva is clothed densely (about a star-diame- 

 ter apart) with short stemmed, shining, whitish yellow stars and dark red, 

 star-based, slightly curved, feathered bristles, all very small, producing, 

 by their colour, the j)attern of lines and patches ; the margin of body and 

 bases of legs clothed with longer, fine, light hairs from simple, conical — 

 tubercular bases, those at the ends somewhat fulvous. The star-tops are 

 not as wide as a spiracle, the bristle from them about o x their length, 

 the simple-based marginal hairs 3 x these and still very short ; seginents 

 o, 4 dorsally dented a good deal, giving the appearance of flat tops to 

 those segments ; segments 8-10 with a lateral dent just above spiracles, 

 the dent being long and transverse (to body); all segments well distin- 

 guished from each other, the hinder margin of each one being higher than 

 the front margin of the succeeding one ; gland rather large, mouth-shaped ; 

 organs of segment 12 with the circular openings white. tSjnracles round, 

 rather small, flush, white, the protrusible white cylinder with feather — hair 

 bristles thinly dark-rimmed. Colour of larva dark or light green with an 

 interrupted, broad, dark red or greenish, dorsal line on segments o-lO ; 

 this line flanked by a more or less bright j^ellow (or whitish) line on each 

 segment, which gets broader towards the hinder margin and runs (mt late- 

 rally along the hinder margin ; a broad, subspiracular. dirty, pinkish band, 

 bordered sometimes by a more or less bright cream yellow interrupted 

 band below : a dark, red spot near the hinder, lower margin of each seg- 

 ment; segments 11-14 dirty pinkish; segment 2 dirty green. L : 9 mm. ; 

 B : 2"7o nnn=:a little more than greatest height. 



Pupa. — The shapr- is quite normal and like the other Nacaduha pupjo.. 

 It is square in front, rounded behind where the anal segment is turned 

 under, the head being a good deal broader than the anal end ; highest at 

 the thoracic apex, visibly higher than at segment G; broadest at segment 

 8 where the wings are somewhat roundly prominent seen from above and 

 they are prominent back to the shoulders; the shoulders are also rather 

 prominent ; the thorax is very convex, large and rounded ; the ventral 

 line is ever so slightly concave ; segment 2 has a straight front margin, 

 the hind-margin is slightly waved forwards dorsally, the dorsal line is
