86 CIDARIA IMMANATA. 



months I have bestowed as much pains as untoward 

 circumstances would permit, may not prove altogether 

 unacceptable. 



To begin with C. russata. On the 11th of August, 

 1863, I captured a female moth ; she at once laid 

 some eggs, from which the larvae were hatched simul- 

 taneously on the 23rd of the same month. I fed 

 them on sallow and strawberry, and they attained the 

 length of half an inch before hybernation. About 

 the 15th of February, 1864, they began to feed 

 again, and had all of them attained their full growth 

 and were spun up between the 10th and the 23rd of 

 April. During the latter month I also captured four 

 or five larvae, and they too were spun up by the 26th. 

 The moths (about fifteen in all), from both bred and 

 captured larvae, emerged between the 5th and the 

 18th of May. Meanwhile, on the 10th of May, I 

 received from Mr. Batty, of Sheffield, one full-fed 

 larva, which he had found on whortleberry; this spun 

 up at once, and the moth appeared on the 27th of 

 May. A few days later, during the first week of June, 

 I obtained four or five batches of eggs from captured 

 females. The larvae from the first of these were 

 hatched on the 11th of June, and the rest in due 

 order; they fed up fast on sallow and strawberry; 

 the first began to spin on the 15th of July. The first 

 moth appeared on the 5th of August, and the rest 

 continued to emerge till the first week in September. 

 I did not set out all of them, but there must have 

 been several dozens. 



Now for the dates of G. immanata. I captured 

 a female moth of the var. marmorata on the 12th 

 of August, 1863 ; she at once laid eggs. Also in 

 the latter part of August and the first week of 

 September I received from Mr. J. B. Hodgkinson 

 (who was then in Westmorland) and from Mr. Batty, 

 of Sheffield, several batches of eggs laid by females 

 of the dark type (they kindly enclosed the moths 

 for my inspection) ; some of these eggs I kept for
