tember, to transform, and two days thereafter the pupa worked itself to tha 

 surface. The moth, which proved to be a $ , appeared May 25th. On 

 the 29th of August I found my second larva of this moth ; it was full fed 

 and considerably larger at the time of pupation than the previous capture. 

 It burrowed into the earth the same day, and a short time thereafter the 

 pupa wriggled itself to the surface, the imago, a ^ , appearing on the 23rd 

 of May. My third larva of this moth was received by post, September 

 I St last, from a friend at Clermont, New York, who informed me that it 

 was found by his gardener, and was thought to be a great rarity, as that 

 important functionary had declared that he had never seen the /ikes before. 

 Strange that sp ponderous a caterpillar should have escaped the gardener's 

 more ponderous foot ! Luckily it was not thought to be a snake, or for 

 the love of St. Patrick he would have counted it among his squashes. It 

 burrowed into the earth on the 6th of September, and in a few days the 

 pupa appeared upon the surface. It would seem from these facts that it 

 matters not at what time the larva pupates, the imago appears at the end 

 of May. It is also made evident that the pupa remains upon the surface 

 of the ground during the winter. 



CORRESPONDENCE. 



ON THE BREEDING OF LEPIDOPTERA. 



On the 5th of December, 1883, I took from a room which had not 

 yet been warmed up, this winter, a number of pupae (Heterocera) of dif- 

 ferent species. These I took to a room having a warmth of from 64-80 

 degrees Fahr. (16-20 Reaumur), to ascertain the amount of warmth the 

 different species of Lepidoptera need to reach the imago state, with the 

 following success. On January i6th, '84, the first imago disclosed a fine 

 specimen oS. Hemaris tenuis. On January 27th, another H. tenuis hatched 

 in good condition ; also a Telea polyphemus, and on February 4th a large 

 female of Apatela lepusculina also disclosed. I have yet a number of 

 pupae exposed to the same warmth, and will report of further success. 



A NOTE ON VANESSA (AGLAIS) MILBERTI. 



In September, 1883, on a Thursday, I took a number of caterpillars 

 of Vanessa Milberti on the common nettle, which were full grown. On
