k ' It suffices to dip these apples into Nitric Ether, and then to suspend 

 them, by means of twine, to the branches of trees at a convenient height 

 for the ready introduction of the insects into the bottle of Cyanide. As in 

 the case of ' sugaring,' the best places are forest glades, edges of woods, 

 sides of roads adorned with trees or hedges, etc. 



"Lepidoptera are so much attracted by the odour of this Ether, that 

 they attach themselves to the apple, and suffer themselves to become com 

 pletely intoxicated by the vapour, remaining in such a perfect state of 

 immobility as to permit, without difficulty, the introduction of the apple 

 into the bottle, and the collection of Lepidoptera in a most perfect state 

 of freshness." 



In the subsequent number of Petites Nonvcllcs Entomologiques (Oct. 

 15, 1871), we find the following result of experiments with this mode of 

 attracting moths :- 



" M. Fallon has tried, in the forest of Senart, the mode of collecting 

 by means of Nitric Ether, of which we spoke in our last number, and has 

 communicated to us a curious observation on the matter. He tried this 

 method three days running, and on the third day he saw, in twenty 

 minutes, his baits literally covered with moths. But the first day not a 

 single moth came, and the second day he scarcely saw any. This shows 

 Entomologists possessed of little patience, whom want of success at first 

 might discourage, that ill-success may be accidental. 



"M. Fallon conjectured that the cause of the absence of moths during 

 the first and second days of Iris trial, might be attributed to the proximity 

 of vines, and the maturity of the grapes, which drew away the moths. 

 This appears to be undoubtedly the case, though it is not perhaps the 

 only cause ; we should as readily ascribe the fact, in part, to a too great 

 abundance of Ether vapour during the first days. Indeed, the vapour 

 of Nitric Ether, sufficiently diluted, has a very decided odour of Reinette, 

 but when it is in large proportion, the Ether character of the odour pre- 

 dominates too much, and it has but slightly the odour oiReinettc. In this 

 condition, Nitric Ether can have but few attractions for moths." 



[nquilinous Moth Larva in Oak Galls. -I have lately bred the 



moth from the little Tineidous larva, referred to on page 119, as infesting 



acorns injured by a pip-like gall. It is a little speckled gray species 



belonging to the genus Gelec/ua, and which I had previously bred from 



. variows other oak galls, and especially from that of Cynips </. ee/itr'itola, O.S.
