The duration of the pupal state as noted by Dr. Booth for August to 
September 2, was 10 to 11 days. At Holly Springs, Mississippi, a 
uuraber of worms pupated between August 28 aud 31. Some of the 
pupae issued after 15 days and others not uutil after 27 days. Two 
others which had pupated September 4 and 7 issued September 20 and 
30, making 16 and 22 days for the pupal state, respectively. Another 
worm pupated August 3L. This pupa was alive, but had not issued at 
last observation, October 20, when it was injured and died later.

The sexes of the Boll Worm moth can usually be readily recognized, 
especially if but a short time has elapsed since their issuance. After 
the females have deposited most of their eggs and their wings have- 
become worn and battered the sex is less easily distinguished. The 
body of the female is noticeably more robust than the male; especially 
the abdomen, which is distended somewhat by the eggs which are being 
matured. The end of the abdomen is ovoid, acute, the tip not provided 
with so large a tuft of thick hairs as is that of the male. The abdomen 
of the male tapering more gradually is slightly longer, of less diameter, 
and more cylindrical. 
When feeding or ovipositing, the flight of the moth is much slower 
than when flying long distances. The moth approaches a flower or 
gland, often steadying itself with the fore legs, in any case fluttering 
its wings rapidly, with antennae in constant motion. Sometimes they 
alight to sip sweets, or perhaps to rest ; in either case the wings are not 
closed down upon the body, but are partially spread and elevated, leav- 
ing bare the abdomen. If, however, the moth alights to hide, the wings 
are folded down closely upon the body. Much the same flight is ob- 
served in the female when ovipositing, sometimes alighting to do so, 
but usually only steadying herself with the fore legs. In the act of 
oviposition, the abdomen is bent forward sickle-shaped, bringing the 
apex squarely upon the surface to be deposited on. The time occupied 
in depositing an egg in this manner is equivalent to the time it requires 
to count three or four slowly. At this rate, and in the interval of flying 
about from plant to plant, some half dozen eggs are deposited, when 
the moth is seen to fly away. So far as can be determined these inter- 
vening flights are for the purpose of feeding and rest from labor. 
Though the habits of the Boll Worm moth have been classed as noc- 
turnal, aud tbey are principally so, yet its diurnal habits are perhaps of 
geater importance than has hitherto been supposed. During continued 
daily observations on the Boll Worm in the field the moth was frequently 
seen flying about, and at times observed to feed. Upon closer obser-
