[44] REPORT 4, UNITED STATES ENTOMOLOGICAL COMMISSION. 
December 30.— Temperature, 40° F., 8 a. m. Wind W. Clear. 
One parasite, Pimpla conquisitor, in box No. 11. 
December 31. — Temperature, 45° F., 8 a. m. Wind W. Clear. 
To summarize : Have placed in box No. 1, 54 chrysalids. Transferred 9 to No. 3 box. 
Twenty-seven came out as moths and one parasite, leaving 17 chrysalids in that box, 
which on last night was upset by a wind and contents lost. 
In No. 2, glass jar, placed 23 chrysalids. Eight have issued as moths and one a 
parasite, leaving 14 chrysalids. 
In No. 3, glass jar, a number of eggs. These have become darker, but otherwise ap- 
pear to be unchanged. 
In box No. 4 placed 13 chrysalids on October 12. On November 9 introduced 60 
chrysalids, making aggregate 73. Introduced, November 17, 25 chrysalids, making 
sum total 98. Removed 19 dead moths November 28, leaving 79 chrysalids. 
Placed a number of moths in box No. 5 on October 15. Of this lot 60 moths were 
out by November 2. On November 17 introduced 25 chrysalids. On November 28 
removed 20 dead moths, leaving a number of chrysalids. There was no development 
in the last 25 chrysalids placed in the box. 
Put up a number of chrysalids in glass jar No. 6 October 15; 3 moths came out by 
31st; 4 dead moths removed on November 28. No further developments. Put up 
101 chrysalids in No. 7 glass box (vivarium), October 20. These developed into moths 
slowly up to November 3, when they commenced to die, and all were dead on the 
November 28, when I introduced 40 fresh chrysalids. At this date, January 2, 1882, 
some of the eggs retain their green color, while with the larger number the color 
is slightly darker brown. From my observation, this as well as previous seasons, and 
from the difficulty of procuring nectar by the last brood of moths, and their conse- 
quent ill condition for hibernation, I conclude that Aletia is to be classed with that 
family of moths that do not hibernate as imago. 
October 21, put up 61 chrysalids in box No. 8. No development in this box until 2 
dead moths were discovered in it on November 28. It remains in statu quo. November 
5, arranged box No. 9 and placed in it 90 chrysalids. There has been in this box no 
development to this date, January 2, 1882. 
Same date, arranged box No. 10 and placed in it 140 chrysalids; no development in 
this box to date. The three last boxes, Nos. 8, 9, and 10, have been placed where they 
have been subjected to atmospheric conditions, and have been kept damper than those 
in the house, and consequently the transformation of the chrysalids has been retarded. 
On November 9 put in box No. 11, 60 chrysalids ; on November 18 there were 20 living 
moths; on November 21, 10 dead and 11 living; on November 28 all moths dead; 39 
chrysalids left in box ; on November 30, 1 ichneumon, Pimpla conquisitor. On Novem- 
ber 28 put up in box No. 12, 80 chrysalids, brought in on November 21. No devel- 
opment to date; chrysalids looking fresh and sound. 
On November 29 put up in glass bottle No. 13, same date, a few chrysalids. No de- 
velopment ; chrysalids looking sound. There has been an exceptional absence of par- 
asites this season. I shall expect a larger proportion from the chrysalids on hand. 
By a review of my report you will perceive that I have a large number of chrysalids 
subjected to various temperatures and conditions, such as to afford a good test for 
ascertaining whether and how Aletia hibernates or survives the winter in this lati- 
tude. 
I shall likewise, in due time, report to you upon the Malvaceous family of plants in 
this locality, furnishing you with list of same, and list of those of the State, as far as 
lies in my power, and will prosecute search for Aletia larva in same. 1 
Hoping that my researches may prove of some interest to the Department, and de- 
siring a continuance of the work, I have the honor to be, 
Yours, truly,
