REPORT 4, UNITED STATES ENTOMOLOGICAL COMMISSION. 



December 30.— Temperature, 40° F,, 8 a. m. Wind W. Clear. 



One parasite, Pimpla couquisitor, in box No. 11. 



December 31. — Temperature, 45° F., 8 a. m. Wind W. Clear. 



To summarize : Have placed in box No. 1, 54 cbrysalids. Transferred 9 to No. 3 box. 

 Twenty-seven came out as motbs and one parasite, leaving 17 cbrysalids in tbat box, 

 wbicb on last nigbt was upset by a wind and contents lost. 



In No. 2, glass jar, placed 23 cbrysalids. Eigbt bave issued as motbs and one a 

 parasite, leaving 14 cbrysalids. 



In No. 3, glass jar, a number of eggs. Tbese bave become darker, but otberwise ap- 

 pear to be uncbanged. 



In box No. 4 placed 13 cbrysalids on October 12. On November 9 introduced 60 

 cbrysalids, making aggregate 73. Introduced, November 17, 25 cbrysalids, making 

 sum total 98. Removed 19 dead motbs November 28, leaving 79 cbrysalids. 



Placed a number of motbs in box No. 5 on October 15. Of tbis lot 60 motbs were 

 out by November 2. On November ).7 introduced 25 cbrysalids. On November 28 

 removed 20 dead motbs, leaving a number of cbrysalids. Tbere was no development 

 in tbe last 25 cbrysalids placed in tbe box. 



Put up a number of cbrysalids in glass jar No. 6 October 15; 3 motbs came out by 

 31st ; 4 dead motbs removed on November 28. No further developments. Put up 

 101 cbrysalids in No. 7 glass box (vivarium), October 20. Tbese developed into motbs 

 slowly up to November 3, wben tbey commenced to die, and all were dead on tbe 

 November 28, wben I introduced 40 fresb cbrysalids. At tbis date, January 2, 1882, 

 some of tbe eggs retain tbeir green color, wbile witb tbe larger number tbe color 

 is slightly darker brown. From my observation, tbis as well as previous seasons, and 

 from tbe difficulty of procuring nectar by tbe last brood of motbs, and tbeir 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 cbrysalids 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 cbrysalids. There has been in this box no 

 development to tbis date, January 2, 1882. 



Same date, arranged box No. 10 and placed in it 140 cbrysalids; no development in 

 tbis box to date. The three last boxes, Nos. 8, 9, and 10, have been placed where they 

 bave been subjected to atmospheric conditions, and have been kept damper than those 

 in the house, and consequently the transformation of the cbrysalids has been retarded. 



On November 9 put in box No. 11, 60 cbrysalids; on November 18 there were 20 living 

 moths; on Npvepaber 21, 10 dead and 11 living; on November 28 all moths dead; 39 

 cbrysalids left inbox; on November 30, 1 ichneumon, Pimpla conqidsitor. On Novem- 

 ber 28 put up in box No. 12, 80 cbrysalids, brought in on November 21. No devel- 

 oj)ment to date ; cbrysalids looking fresh and sound. 



On November 29 put up in glass bottle No. 13, same date, a few cbrysalids. No de- 

 velopment ; cbrysalids looking sound. There has been an exceptional absence of par- 

 asites tbis season. I shall expect a larger proportion from tbe cbrysalids on hand. 



By a review of my report you will perceive that I have a large number of cbrysalids 

 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. 



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,
