COMMON BUTTERFLir.S OF THE PLAINS OF INDIA. GjO 



slightly back, tliu riirvo being very slight, iind reach only the level of head- 

 vertex : they are eiinal iu length to half the centre ones ; the outer margin of 

 these side-horns bears three simple spines, the bottom one the longest, the 

 margin of head beneath these horns has two or three small spines ; between 

 the vertex-horns are two moderately large, sharp spines, out' on each side 

 of dorsal line ; the colour of head is green like the body, the jaws are 

 rose-coloured, sides of head just above jaws with a rose coloured s-hort stripe 

 in front of which is a yellow stripe reaching to base of lower horn ; colour of 

 central horns green covered with small tubercles bearing each a fine semi- 

 adpressed seta ; tlie side -horns rose-coloured with tuberculous surface also :, 

 the central horns are round-topped, the side ones bluntly pointed. The seg- 

 ment 2 is much narrower than head ; the anal segment is the narrowest part 

 of the body. Surface of body covered with irregular rows of small yellow 

 light tubercles, hemispherical in shape, each bearing a small white seta bent 

 back at the tip, a golden-yellow subspiracular band composed of rather large 

 hemispherical tubercles each bearing a small recurved seta : this baud not ex- 

 tending to segment 2. Colour of body dark green with, sometimes, a large 

 white circular mark dorsally on segment 7 which may occupy half the width 

 of segment or less, or may be entirely wanting or be reduced to a small rose- 

 coloured spot. L: 45mm.; B : 7mm. ; L.of middle horns: 4mm.; of outer 

 horns : 2mm. 



Picpa. — The shape is like that of Ch. imna only a little more elongated. 

 Head square in front and convex transversely above, flat below, broader behind 

 than in front. Wings slightly expanded parallel to each other from 

 middle of thorax to segment 7 ; body is broadest at segment 8, 

 the distance from end of wings to cremaster is only ^ the total length 

 and that part of the pupa is more or less hemispherical in shape, the 

 cremaster being fixed well the ventral side of the apex of the sphere, or these 

 abdominal segments are broad dorsally and narrow ventrally which is saying 

 the same thing ; the cremaster is nearly perpendicular to the longitudinal axis 

 of bodj- and is moderately long, strong and square in transverse section ; at 

 its base on each side are three spherical little tubercles as well as two some- 

 what flattened ones in front : 8 in all ; spiracles green, oval with a white 

 central slit. There is hardly any constriction ; the thorax is long, convex to a 

 small degree and with a tendency to dorsal carination. The surface is finely 

 rugose under lens, somewhat shiny. The colour is grass-green ; a minutely 

 marbled white lateral abdominal line ; another white line above spiracles ;. 

 front margin of head continued over shouldeis along wings to segment 7 also 

 white : cremaster and its tubercles reddish brown. L : 13mm ; B. 8mm. at 

 thickest part. 



Erjrj -Spherical, with longitudinal ridges fine ; colour translucent yellowish 

 with a broad dark red irregularly margined zone round the upper half. 



Habits. — The eggs are laid on the upperside of a leaf in the hot sun. 

 The larva lives on the upperside (.»f a leal making a Led of silk to
