dead in No. 11; 11 moths in No. 11; 7 dead in No. 7. Visited a field of fresh land 
cotton, where the foliage was partially frost-bitten but much still fresh. Found one 
flg f. recently deposited, and some chrysalids. Few insects noticeable. Placed 7 
chrysalids in No. 11. Sent you 3 boll worms (Heliothis), taken from tomato.

November 25. — Temperature 20° F., 7 a.m. Freezing and char. Visited a field. 
Found the plant in too m sat isfaot < >r\ a Mate t«» make any examination, the effect -of 
the severe freeze of previonfl Bight. 
November 26. — Temperature Saf 
iperaturo 30° F., 6 a. m. Wind north. 
November 28. — Temperature 40° F., 8 a. m. Wind north. Removed 20 dead moths 
from box No. 7. Introduced 40 chrysalids into same, brought in on 21st instant. 
Moth in a torpid condition. 
Put up 80 chrysalids in box No. 12, brought in on Slit instant. Removed 4 dead moths 
from No. 6; 2 moths out in No. 8; 20 dead moths removed from No. 5; 19 dead 
from No. 4. Sprinkled dry earth Olie-fourth of an inch thick over chrysalids in 
these two boxes and replaced ihem on the eaith. No development iii boxes Nos. 9 
and 10. 
On close examination at 1 p. m. found the mollis supposed to be torpid all dead. 
Removed 36 from No. 4; 2 from No. 1; 19 from No. 11; 32 from gauze bag. 
Not a moth in any of my boxes living or dead. Temperature at 1 p. m. 64° F. 
Mollis living ami in motion on the -1st, and supposed t<> be living for some days 
subsequently, as they did not change their natural position, were all killed doubtless 
by the freeze of the 2.">th instant. This would indicate that the moth cannot survive 
a temperature belon K> j or 20° F. 
In regard to copulation, from my observation, it is carried on most actively at twi- 
light. When observing my vivarium by lamp-light I have witnessed no demonstra- 
tion in that line. As eggs, however, are abundantly laid on the glass, leaves, and 
stalks of cotton, and the wooden sides <>f my boxes, procreation must go on normally.

vino ran on a cedar tree in a cot ton-held. They appear to be sound. Put up in glass 
bottle No. 13.
