pea green covered with microscopic blackish hairs arranged 
more or less in transverse rows on the tops of the transverse 
folds of each segment. Hairs arise from prominent tu- 
bercles. Lemon yellow interrupted suprastigmatal line 
very thin. Wide stigmatal line whitish green. Below the 
stigmatal line the body is lighter green. The numerous 
hairs are longer and more lightly colored. Just dorsal to 
the stigmatal line is an irregular line of black to iridescent 
tubercles of various sizes. They are most numerous on the 
thoracic segments, least numerous on the anal segments. 
Legs and prolegs light transparent green. Tips of claws on 
legs slightly fuscous. 
Chrysalis 
Length 32 mm. Very light green to yellow. The anterior 
end terminates in a long thin club-shaped tip. In color this 
is burnt sienna. From it extend two lateral lines of the 
same color. Each extends along the dorsal edge of the 
wing pad then continues as a suprastigmatal line. A mid- 
dorsal line of similar color passes from the first abdominal 
segment to the tip of the shallowly bifurcate cremaster. 
Edges of eyes same color. Body smooth with no prominent 
hairs or tubercles. The chrysalis is very stout-bodied in the 
thoracic region bulging considerably ventrally and slightly 
laterally. It is suspended in the manner characteristic of 
Pieridse and Papilionidse with a girdle around the thorax. 
Oviposition is most frequent in the late forenoon and early 
afternoon. The butterflies circle around large bushes of 
Cassia spectabilis, deposit a single egg, then another a few 
feet away. One insect may lay as many as fifteen eggs on 
a single bush at one visit and repeat the performance at a 
subsequent visit. Each egg is laid singly on the edge of the 
leaf. It is fastened by its blunt base but reclines on its side. 
Eggs laid May 4 hatched four days later on May 8. Each 
instar requires on the average four days. One larva which 
pupated May 5 emerged May 14, nine days having passed.
