interrupted line. The stigmatal line ranges from light green 
to white. Numerous colorless hairs arise from prominent 
warts. The body is microscopically mottled with the warts 
arising from dark green areas. Areas between are lighter 
green. The blunt shiny hairs of the second instar are much 
reduced and not easily distinguishable from the other hairs 
of the body. Short fuscous hairs on the head. Head surface 
finely granular. 
Chrysalis 
Length 6.5 to 10.8 mm. Typically pierid-shaped. Dark 
greenish glaucous. Mottled with light and dark green. Just 
prior to emergence the dark green mottling assumes a light 
fuscous appearance. On the wing pads this is in the form of 
dendritic more or less parallel lines in the same direction as 
the veins. Those on the tongue case are at right angles to 
the axis of the tongue. Fewer on abdominal segments ; none 
in intersegmental areas. Absent on dorsal side of abdomen 
except for an irregular para-dorsal row of splotches. Mark- 
ings increase laterally and ventrally. Surface smooth. Cre- 
master blunt. Spiracles rimmed with fuscous. Mouth-parts 
and especially antennse are frequently outlined in fuscous. 
Eggs were laid May 29 and 31. Some hatched two days 
later. The duration of the different stages of this species 
varies extremely. Color markings also show a wide varia- 
tion. Each instar may require from three days to a week or 
ten days. The pupal stage requires an average of seven 
days. Females have never been observed ovipositing earlier 
than nine o'clock in the morning. Eggs are laid on very 
small seedlings of Bidens leucantha. Many false starts are 
made before an egg is actually laid. A female may visit sev- 
eral seedlings and at each one go through the motions of 
oviposition without extruding an egg. Then she may lay 
several eggs in rapid succession each on a different seedling. 
Eurema lisa (Bdv. & LeC.) 
First Instar 
Head height .28 mm. ; head width .3 mm. Head trans- 
parent and nearly colorless. Smooth with few hairs. Length 
of body 1.7 mm. Transparent yellow. Green in gut visible. 
Longitudinal rows of rather long fuscous tapering hairs.
