120 BOTYS PANDALIS. 



male and female, quietly sitting on the leno cover ; 

 this, without disturbing the moths, I removed to 

 a fresh pot, and on the 24th found presumptive 

 evidence of their having paired, in a patch of the deep 

 yellow eggs laid on the white surface near the bottom. 



Whether in our climate the imago would emerge at 

 this time of the year when under natural conditions I 

 should think is very doubtful ; in a warmer climate it 

 seems to be regularly double-brooded, for Gruenee 

 says it flies "en mai, puis juillet et aout;" perhaps 

 therefore in hot summers a second flight of moths 

 might occur in August with us, but hitherto only one 

 flight has been recorded, the date of which Wood, 

 Humphreys and Westw^ood, and Stainton agree in 

 giving as (the beginning of) " June." (William 

 Buckler, 5th November, 1880; E.M.M., December, 

 1880, XVII, 156—158.) 



BOTYS HYALINALIS. 



Plate OLIII, fig. 2. 



On the 27th of July, 1883, Mr. W. R. Jeffrey 

 captured a female moth of this species, which 

 deposited her eggs between the 30th of July and 

 the 2nd of August. The larvse hatched on the 11th of 

 August, and on being supplied with leaves of various 

 plants growing in the locality where the moths 

 were flying, soon showed their preference for those of 

 Centaur ea nigra, at once spinning little webs along the 

 side of the midrib towards the stem; they ate away 

 the under-side, leaving the upper cuticle untouched, 

 and thus making little transparent blotches, which 

 showed where they were feeding; they were, however, 

 themselves so glassy and translucent that they were 

 most difficult to detect, and hence several were lost or 

 destroyed in changing their food. They continued to 

 grow till the beginning of October, and as it then 

 became apparent that they would hibernate, Mr.
