SOOPULA FBERUGALIS. 173 



to the grenadine in such a manner as to form a 

 cocoon, lined throughout with silk, which, from 

 above, had much the form of a pasty ; the imago, a 

 female Scopula ferrugalis, appeared at the end of 

 August, 1877. 



Very nearly at the same date Mr. Jeffrey dis- 

 turbed a female moth from some plants of E. canna- 

 binum, which he captured and shut up in a pill-box ; 

 and on the white paper lining she deposited about 

 thirty eggs, in little groups of twos, threes, and fours, 

 and when these had been sent to me (12th of Sep- 

 tember) she continued to lay a few more on the side 

 of a jam-pot, into which she had been put, together 

 with leaves of the food-plant. We doubted the fer- 

 tility of the eggs at first, but thej all hatched in due 

 time, those in my possession on the 14th and 15th of 

 September, and all the larvas matured and spun up, 

 some in the leaves of their food, and some in pieces of 

 muslin supplied for the purpose. 



Meanwhile both Mr. Jeffrey and myself did not 

 forget to look occasionally on other plants, and on 

 the 19th of September he found several of the larvas 

 far advanced, others very young, on the Eupatorium, 

 and on the 10th of October a few nearly full-fed on 

 Stachys palustris, and, curiously enough, one or two 

 more under strawberry leaves in his own garden ! — a 

 fact which accounted very well for his little boys 

 having' earlier in the season disturbed several of the 

 moths from some fagots of wood there, which at 

 the time was a puzzling circumstance. On my part, 

 besides finding one on E. cannabinum, I took a full- 

 fed larva on Stachys sylvatica on the 4th of October, 

 and on the 11th found a solitary plant of Arctium 

 minus much ravaged, and after a careful search de- 

 tected one full-grown larva still remaining, the others, 

 which I reckoned might have been twenty in number, 

 having fed up and gone. To my surprise the larva 

 I had taken on Stachys sylvatica, which had pupated 

 in a day or two, produced the moth on the twenty-
