darker green marks along sides just above each dot, 
each mark lying diagonally across each segment. The 
It rva is a beautiful object to look at. As the larva grows 
older and bigger the dark green line fades. 
Full-grown larwa: Head, blackish brown; body, 
yellow-green, humped, points of each segment having 
one stiff white hair, line along back reddish-purple, 
small short hairs all over the body, diagonal line on each 
segment light green, just discernible, small black dots 
along full length of sides. Fringe of hairs along sides 
of body; fringe of longer hairs, look like some shades o!' 
brown, on each end of larva. 
The larva is attended by a small brown ant, usually 
one to three; The larvae feed on a pea-like vine, here 
usually called wild sweet-pea, because the flowers are 
almost as large as the garden sweet-pea. They prefer the 
flowers and buds. 1 collected most of my larval speci- 
mens inside the green seed-pods because the flowers ha' 1 
fallen. The flower is a mauve or lavender colour.* 
Pupa: Bound and hairy. Colour soon after pupation : 
Head, thorax and wing-cases, are clear green in most 
darker green in some with black spots over each eye- 
case; the remainder has scattered black dots and spots 
all over it. Line of black dots along thoracic ridge con- 
tinuing full length of abdomen. 
Abdomen: Pinkish-white tinged with green, minute 
black dots all over it, line of black dots along each side 
corresponding with dots on larva,. 
As the pupa develops the butterfly inside, the colour 
changes until it becomes pinkish-cream or white with all 
the above-described spots and dots upon it. Some pupae 
have more black dots on them than others. The pupa is 
fixed with cremaster and central girdles. 
The foregoing description was discovered in part 
about five years ago. At that time only the last instar 
(full gr wn) pupa and butterfly were obtained. I found 
lots of egg® laid upon the host plant and was able to 
stand and watch the females lay their eggs on the 
flower-buds. The pressing need to work my farm with- 
out any help during the war prevented me from extend- 
ing my observations. However, this year I was able to
