THE COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 445 



tersection or corner; the walls about as high as one-third of a cell-diameter, 

 the spine as long as the walls are high; the concave bottoms of the cells minutely- 

 pitted. The largest cell-diameter is 0-075 mm; the walls are 0- 05 mm. in width, 

 the cells round the m'icropyle are at least 0-05 mm. broad; the micropyle 

 funnel-shaped and 0-lmm. at the mouth. Colour is light-green in the cells, the 

 walls are enamel-white, the spines translucent-white, B: 0'9 mm., over 1 

 mm. with the spines; H: 0*45 mm. without spines. 



Larva (PI. II, fig. 22). — The shape is somewhat abnormal and the horizontal 

 section would be a very good representation of a rather short boot-sole, the heel 

 being the posterior end of the body. The head is always hidden under segment 

 2 ; segment 2 is more or less semi-circular or rather trapeze-shaped, the narrowest 

 side being the front margin, the margin is somewhat tumid and there is a dorsal, 

 central, apparently triangular (really 4-sided) depression situated on a dorsal 

 tumidity again, the bottom of the depression is glabrous with fom' or five 

 minute tubercles, the thickened border dented on the front margin in the dorsal 

 line forming a small triangular sinus ; the body is broadest and highest at about 

 segment 6, increasing from segment 2 backwards, after which it decreases in 

 height and breadth gradually to the hinder margin of segment 8, increasing 

 again in height and breadth, though in a lesser degree, in segments 9-11 ; the 

 dorsal slope being more or less gradual from 6 to 11, 12 after which 13-14 have 

 a much more steep slope : these two end segments are short and narrower by 

 a good deal than segment 12 ; segments 8, 9 are generally narrowed into a kind 

 of waist, 7 and 10 being broader — generally, because in certain positions 

 Avhich the larva assumes, this is not the case ; in repose the hinder margins of 

 all segments 3-10 is higher than the front margin of the succeeding segment ; 

 the ventrum is flat ; all segments are well marked and the dorsoventral 

 margin is transparent. The /«ea(Z is rather small, round, shining, yellow with 

 a large triangular, white-outlined elypeus and black eye-patch and mandibles. 

 The surface of the body is very shining and finely and distinctly pitted as also 

 laterally corrugated ; the free margins of segment 2 and segment 14 as well as 

 the ventrum on the sides are all sparsely covered with minute, erect, stiff, 

 dark hairs. There is a small, transverse gland on segment, and the organs 

 on the segment 12 are small and cylindrical when protruded. Spiracles rather 

 small, oval and more or less the same colour as the body. Colour of the body- 

 is oily green-yellow with a broad, electric-blue dorsal, lateral and subspira- 

 cular band, the whole length of larva from segment 2 to segment 12 ; 

 segment 13 has only a dorsal smudge of blue. L : 17 mm. to 23 mm. ; B : 

 7 mm. 



Pupa (PI. II. fig. 22a). — The sJiape is normal but very stout. The hmd- 

 frons is perpendicular to the longitudinal axis of pupa ; segment 2 has the dorsal 

 slope in continuation of the front slope of the thorax ; the thorax is somewhat 

 flattened on the apex and the posterior slope is steep and short ; the 4th segment 

 is nearly as high as the thorax so that there is little hump about the latter ; the 

 dorsal line ascends gradually from segment 5 to segment 7 which is the highest 

 part as well as the broadest of pupa ; the slope from 7 to end is short and steep 

 to the end which is rounded, segments 13, 14 being tmned under; segment 2 

 is rounded in front, broadens out to its hinder margin from where the sides of 

 the pupa are parallel as far as segment 5 ; after which the abdomen swells out 

 again to segment 7. The surface of pupa is slightly rugose imder the lens. The 

 spiracles of segment 2 are linear, slightly raised, light ; the rest are linear, light- 

 colom-ed slits in the middle of a round, dark surface, each sunk in a shallow 

 depression. Colour of pupa is brown of many shades dorsally with a darkish, 

 dorsal longitudinal line and a black, circular spot at edge of wing (laterally) 

 on segment 5; ventrum dirty greyish. L: 12*5 mm. and over; B: nearly 

 7' 5 mm ; H : 7 mm.
