Table 1. Summary of variables for seven instars of individual no. 4 of Rearing 
lot 80-30. (P = pale, pink; D = dark; G = green; S = skeletonizer, soft; H = hard; W = 
eats whole leaf).

constructed by these instars, were soft and less dense than previous 
sections. The apical 2-3 cm of these tubes were extremely diffuse 
and the larvae inside could be seen clearly. Having consumed all 
nearby leaf, hungry larvae dismantled this diffuse portion and 
shifted it laterally until additional leaf surface was located, some- 
times on other leaves of the same plant. 
The final instar larva (G) (Figure 4) was about 7 mm long, lacked 
secondary setae; had prolegs on abdominal segments 3-6 and 10; 
crochets uniordinal, arranged in a circle; prespiracular wart of 
prothorax long, curving part way around spiracle, and bearing three 
setae; mesothorax with a single seta on tubercle pi; abdomen with 
setae alpha and beta widely separated, setae eta and kappa adjacent, 
seta beta on ninth segment placed higher up than alpha, and setae 
beta on ninth segment the same distance apart from one another 
across the dorsum as on previous abdominal segments; head with 
front extending about one-half the way to the vertex. Because the 
two sides of the mesothorax bore slightly different setation, on the 
specimen studied, both are illustrated in the setal maps (Figure 4). 
For ease of comparison, the map of the right mesothorax is shown 
in mirror image. 
The day before pupation, final instar larvae abandoned their 
tubes and dropped to the floor of the cage. No cocoon was 
constructed. 
The pupa (Figure 5) was ovate in outline, 5 mm long, 2 mm wide; 
with wings extending slightly beyond caudal margin of fourth 
abdominal segment; apical 1.3 mm of antennae adjacent on the 
meson except at their extreme tips, and bearing a distinctive raised
