1878. 201 



first, and over that, of fine cambric ; the larva made a hole through the 

 grenadine, and crawling between the two coverings, cut through the 

 cambric in a horse-shoe curve with about five-eighths inch radius, and 

 drawing this partially detached portion together with silk, fixed it 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 S. ferrugalis ? , appeared at the end of August, 1877. 



Yery nearly at the same date, Mr. Jeffrey disturbed a female 

 moth from some plants of E. cannabinmn, 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, September 12th, she continued to lay a 

 few more on the side of a jam pot, into which she had been put, to- 

 gether with leaves of the food plant. We doubted the fertility of the 

 eggs at first, but they all hatched in due time, those in my possession, 

 on September IJith and 15th, and all the larvae matured and spun up, 

 some in the leaves of their food and some in pieces of muslin supplied 

 for the purpose. 



Meanwhile, both IMr. Jeffrey and myself did not forget to look 

 occasionally on other plants, and on September 19th, he found several 

 of the larvae far advanced, others very young on the Uupaforiicm, and 

 on October 10th, a few nearly full fed on Stachys pcdustris, 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 faggots 

 of wood there, which, at the time, was a puzzling circumstance. On 

 my part, besides finding one on E. cannahinum, 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, detected 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 S. sylvatica, which had jjupated 

 in a day or two, produced the motli on the twenty-fifth day, i. e., Oc- 

 tober 20th, and Mr. Jeffrey bred one in a cage out of doors on the 9th 

 of September, and the Eev. J. Hellins, to whom I had sent two of the 

 larvse reared from eggs, b^ed one moth on the 17th of the month, 

 and the second moth in the first week of this present January, 1878. 



"Whether there are two broods or more of ferrugalis, I am, at 

 present, unable to say, but that some few are bred late in the year, 

 and probably hibernate till spring, has now become evident.
