78 SPOLIA ZEYLANICA. 
white subdorsal band, extending from the lower edge of the 
dark dorsal bar to the upper side of the sub-dorsal hair papules, 
which were thus strongly accentuated in appearance. The 
white bar was most marked on abdominal segments 1-4 
and 7-8. In this larva the median spot on abdominal segment 
7 was red. This larva pupated in stage 2, never assuming 
the appearance of the third stage, but the second stage was, as 
usual, confined to one instar. It gave rise to a normal male 
imago. 
In another case I found a larva in stage 3 which possessed 
a broad white lateral suffusion from the meta-thorax to the 
anal segment. This larva gave rise to a normal female. It is 
thus apparent that the white bar is not indicative either of 
sex or of larve which pupate without assuming the appearance 
of the third stage. 
Pupa.—tn no ease have I found a cocoon formed. The male 
pupa is 15 mm. long, chocolate-brown, slender. The wing 
cases are fully formed. The female pupa is 25 mm. long, 
ovate, with noticeably small wing cases. It is free, or attached 
to a twig by a few silk threads. The colour is similar to the 
male pupa. Pupz of both sexes have tufts of short lighter 
hairs in rings on the abdominal segments, a few scattered 
tufts on the thoracic portion, and a collection of closely set 
small tufts around the head end. Both sexes have an obtuse 
anal spike. 
Imago: Male—KEKxpanse 30 mm. Fore wings brown, 
lighter basally, across which portion are three ill-defined 
crenulated dark lines from costa to dorsum. The inner half 
of the costal margin is dark, but exterior to cell there is a 
whitish patch on costa, which may be very noticeable, or 
nearly uniform with the brown of the wing. ‘The outer portion 
of the wing is dark, with a post-medial lunular line of darker 
brown, divided from the outer dark area by a lighter brown 
line of lunules. There is a dark spot in cell, and a dark lunule 
at the end of it. The median nervure is dark and prominent, 
especially from the sub-basal line to end of cell. The terminal 
cilia are yellowish at the extremity of each vein. The hind 
wings are a uniform somewhat lighter brown, but in one 
specimen (which originated from the above described larva
