130 THE CANADIAN ENTOMOLOGIST. 



capture of the imago on July 19th raises the other question : — Were these 

 belated individuals of the spring brood, or abnormally early specimens of 

 the summer brood ? 



Eggs laid at about the middle of July would not hatch until early in 

 August, at a time when those first hatched would already be nearly one 

 month old. In September I found full grown and less than half grown 

 larvae together in one stem, and the full grown larvse were getting ready 

 to spin up. Those half grown at that time increased very slowly, and up 

 to the first weeks in October were still feeding. Meanwhile, the larvae 

 that spun up early in September were quiescent within the cocoon, and 

 up to date — February 23rd — none of them have transformed to pupae. 

 To get two broods into one season, all the periods must be considerably 

 shortened and the development must be much more rapid. 



For these reasons I believe that we have in New Jersey and north- 

 ward one brood only ; that the time of appearance of the imago extends 

 over nearly if not quite one month, and that six weeks may be the period 

 of flight; that at least 15 days are required for the eggs to develope ; 

 that the larva requires from seven to eight weeks to come to maturity ; 

 that the larva remains unchanged within the cocoon during the winter. 

 The date of pupation and the period passed in that stage has not yet 

 been ascertained. I hope Dr. Kellicott will be able to ascertain this posi- 

 tively, and thus complete the life history of the insect. The economic 

 problem of how best to deal with the species need not be discussed in 

 this connection, but is much simplified by the better knowledge we have 

 of its habits. 



OBITUARY. 



THE ABBE PROVANCHER. 



It is our painful duty to record the death, in his 72nd year, of the 

 Abbe Leon Provancher, who for many years, despite great discourage- 

 ments and disadvantages, laboured zealously and assiduously to develope 

 and disseminate a knowledge of the natural history of Canada, and 

 especially of his native province. He was born in 1820, at Becancour, 

 Que., and for some years was Cure of Portneuf, and one of his earlier 

 entomological writings was a list of the Coleoptera of that district. 

 Compelled by enfeebled health to relinquish the regular and more active 

 duties of the ministry, he removed to Cap Rouge, near Quebec, and
