COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 1149 



89. Delias eucharis- Upperside : white. Fore wing : the veins broadly 

 lalack, this colour broadened triangularly at the termination of the veins, 

 costal margin narrowly black; a broad, black, postdiscal, transverse band 

 from costa to dorsum, sloped obliquely outwards from costa to vein 4, thence 

 parallel to termen. Hind wing with the veins similar but for three-fourths 

 of their length much more narrowly black ; a postdiscal, transverse, black 

 band as on the fore wing but much narrower, curved and extended only 

 'between veins 2 and 6 ; beyond this the veins are more broadly black and 

 this colour, as on the fore wing, broadens out triangularly at the temina- 

 tion of the veins ; the interspaces beyond the postdiscal, black band pink, 

 due to the vermilion coloration of the underside showing through. Under- 

 side : fore wing similar but the black edging to the veins much broader, 

 the upper two interspaces beyond the postdiscal, transverse band tinged 

 with yellow. Hind wing : ground-colour bright yellow, the veins and trans- 

 verse, postdiscal band as on the upperside but much more broadly black, 

 the latter extended from the costa to vein 2 ; the interspaces between the 

 veins beyond the postdiscal fascia with a series of broadly lanceolate or 

 cone-shaped, vermilion-red spots, each spot very narrowly edged with 

 white ; the basal portion of interspace 6 white, in contrast to the bright 

 yellow of the ground-colour. Antennse black ; head, thorax and abdomen 

 white, the apical joint of the palpi black ; the head and thorax with a 

 mixture of black hairs that gives these parts a grey-blue appearance. 

 Upper and undersides similar to those in the female, but the black edging to 

 the veins and the postdiscal, transverse bands on both fore and hind wings 

 very much broader. Expanse : 80-85mm. 



Egg. — Light yellow in colour ; white immediately after laying ; very 

 shiny, of an ordinary size, ovoid in shape, truncated at bottom, standing 

 erect, smooth with indications of course longitudinal striation. 



Larva. — (PI. 1, figure 17.) Head round, flattish, black, with a white line 

 at base of jaws and mandibles ; antennse white, black tipped. Body 

 ^cylindrical ; 2nd segment slightly smaller than head ; anal segment ends 

 jound and is short. The colour of the body is a greasy, greenish-yellow 

 brown. The front half of the 2nd segment is white, with a black patch 

 dorsally behind the white part ; there is a lateral white line on segments 2 

 and 3. The head is sparsely covered with long, white hairs, those near the 

 top of face being longer than the others. The 2nd segment has a collar of 

 6 longish white. hairs. There is a subdorsal row of long, white, erect hairs, 

 one to each segment proceeding each from a white tubercle; there 

 is also a dorsolateral and supraspiracular row of white hairs, each 

 hair proceeding from a white tubercle. The body is besides covered 

 with small white tubercles, each surmounted by a small erect, white 

 hair. Spiracles smallish, oval, light. Ventrum yellow. L : 40mm.; B :
