THE COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 671 



removed ; surface covered with erect, not very short, finally bifurcated 

 hairs ; each segment also with a subspiracular tuft of similar erect, longer, 

 yellow hairs ; segment 3 has these hairs along front margin ; segments 2 

 and 14 have longer hairs round front and hinder margins respectively. 

 Colour of larva green-rose, ventrally green ; true legs very small. L: 11mm 

 B : 4" 5mm. 



Pupa.- — The shape and mode of attachment are those of Tajuria cvppus. 

 Head small, hidden under a somewhat large segment 2 which has its front 

 and hinder margins quite flush with the pupal surface ; front of head is 

 in a plane perpendicular to longitudinal axis of pupa as is also the front 

 slope of the thoracic hump ; this hump considerable and very slightly 

 flattened on dorsum, also slightly compressed laterally behind apex ; pupa 

 constricted dorsally behind thorax (segments 4, 5) considerably ; segment 

 6 sloping up again, nearly as high as apex of thoracic hump, segment 7 

 little lower ; the dorsal line of segments 8-11 is at an angle of about 60° 

 with a straight line joining the extreme ends of pupa ; that of segments 

 12-14 is perpendicular to that line ; in lateral outline the pupa increases 

 in width from head-frons backward to shoulders, these somewhat prominent 

 and smooth, the pupa becoming first gradually narrower and then again 

 broader in a concave curve to the broadest part about common margin of 

 segments 7 and 8 ; thence decreasing rapidly in width to form the more or 

 less cylindrical portion composed of segments 10-14, segment 14 being 

 generally broadened out to hinder margin having thus the appearance of a 

 horse's hoof by which the pupa is attached, the " hoof " being provided with 

 booklets round its extreme margin for this purpose ; the ventral line ie 

 straight from front to end of wings, then generally bent, forming an angle 

 less than 180° with the longer front portion, to run straight to cremaster. 

 Seen from above the oiitline is shaped like a fiddle without a handle. 

 Spiracle of segment 2 hardly indicated ; the rest of the spiracles longly oval, 

 yellow-brown, situated on the top of little swellings. Surface of body 

 shiny, pitted with a subdorsal, tubercular swelling on segments 6, 7, 8 ; 

 these swellings or ridges parallel to segment margins and produced laterally 

 down towards spiracles. Colour is as follows : — head, segment 2 and front 

 slope of thorax with wings are enamel-white with a greenish tinge ; apex 

 of thorax patched red-brown, behind which the rest of thorax and segment 

 4 are lighter brown ; the abdomen yellow brownish-green with a lateral, 

 black mark on segment 5. Looking at the pupa from above and slightly 

 in front, the shape and markings give the impression of a monkey's face, 

 segment 2 being the mouth, the front slope of thorax the upper lip; the 

 brown spical thoracic patch are the nostrils, the lighter red-brown hinder 

 part of thorax the bridge of the nose, the black spots on segment 5 the 

 eyes and the swollen abdomen at segments 6, 7 and onwards represent the 

 large forehead, the ridges on those segments parellel to segment margins 

 looking like great wrinkles and enhancing the striking resemblance. L : 

 7mm. ; B : 4-5mm, at segment 6/7 ; H : 4mm. at segment 6^= the breadth at 

 shoulders. 



Habits. — The eggs are laid singijr among tlie insects upon which 

 the larva feeds ; quite a nn:nber sometimes to each colony of these. 

 The larva emerging bnrrows into one of the yonng lice and eats it 

 tip leaving nothing bnt the covering ; this is continued as the larva 

 grows and it is covered by the white excretion of its victims ; it 

 lives amongst them and is not always easily distinguished from 

 them ; the white covering is attached to the larval skin by the 

 forked hairs or bristles described above. When the caterpillar is
