torpor of hybernation, there must be a degree of temperature 

 sufficiently high to prevent freezing. 



There is no perceptible difference between the imago — the 

 butterfly — of the early and late broods of the Vanessa. But I 

 think, that the shells of the eggs, deposited in the Spring, by the 

 hybernating female, are much harder and more " shell-like " in 

 their nature, than those deposited by the females of the next 

 brood ; and that the larvae of the second brood consume more 

 food than those of the first brood. In point of fact I am posi- 

 tive of the last assertion. I have in years past reared large num- 

 bers of the Fanessa, from the egg to the butterfly, in my cocoon- 

 ery. And, for a number of seasons, I have selected several lar- 

 vae of each brood, of as nearly as possible the same size and 

 healthfulness, and weighed the quantity of food consumed by 

 each lot. I found, in every case, that the larvae, which produced 

 the late, or hybernating butterflies, consumed between five to ten 

 per cent, more food, during the period embraced between the 

 tenth day after hatching, and the day of transformation into the 

 pupa, than those of the earlier brood. 



In closing these brief and dry notes, I will say, that there are 

 many points connected with the life of the Vanessa, and many 

 obscure data to be cleared up, that are worthy of the attention 

 and close study of any one, whether he be an entomologist or 

 not.

 the nasal organs in this disease. Dr. Daly, of Pittsburgh, U. S.
