rather exposed to view than otherwise. And from the occur- 

 rence in one spot of larvae, adult and newly hatched, it 

 would seem that a succession of imagos are attracted to the 

 same locality, though it will sometimes happen that the 

 nettles have been so far stripped that the latest out have, 

 perforce, to migrate before they are full grown. — J. R. S.

Late emergence of Lepidoptera. — It would be easy, if not 

 particularly interesting, to bring together many proofs of the 

 great check given to insect-life by the ungenial weather of 

 early summer, though the effects were, as was to be expected, 

 very various in different counties. I propose to cite a iew 

 instances, in addition to those already given, showing how 

 some of the moths occurring in the London district were 

 affected thereby. The general broods of the following larvae 

 were two or three weeks in arrear of their usual time : 

 namely, Odonestis potatoria, Arctia caja, Bombyx neustria, 

 Liparis auriflua, Abraxas grossulariata (in open places, not 

 so in gardens), Cheimatobia brumata, Hybernia leucophearia, 

 H. rupicapraria, Selenia illunaria, Diloba caeruleocephala, 

 Cosmia trapezina, and Yponomeuta padella, the latter appear- 

 ing in good numbers at last, greatly to the discomfiture of 

 some persons who, priding themselves upon their hawthorn 

 hedges, hoped they had escaped the ravages of the species 

 for the present season. Of imagos, amongst the Macro- 

 Lepidoptera, I might cite many instances : some, however, 

 especially amongst the Noctuae, are so capricious, that what 

 is a late emergence in the experience of one observer is an 

 average appearance in the estimation of another. The follow- 

 ing were noticeably behind the wonted period in London, or 

 in the country south and east of the metropolis, as seen or 

 captured by myself: — Melanippe montanata, M. galiata, 

 Cabera exanthemaria, Anaitis plagiata, Camptogramma 

 bilineata, lodis lactearia, Hemerophila abruptaria, Acronycta 

 Psi, Acidalia straniinata, Euclidia Mi, and Orgyia pudi' 

 bunda. From the paucity of Tortrices and Crambi on the 

 wing in June, it was evident that in these families the 

 unfavourable effects of the season had also been felt. — Id. 



Agamogenesis in Sphinx Ligiistri. — Perhaps some of the 

 readers of the ' Entomologist' will recollect, or, on referring 

 to vol. V. p. 375, will find, a communication from me on the
