The recent abundance of hibernated Butterjlies, Sfc. — The feature of the spring 

 and early summer of 1892 has undoubtedly been the occurrence in unusual numbers 

 of Vanessce, and more especially lo, Atalanta, and cardui. The latter has appeared 

 in such quantity as to strongly suggest immigration ; but no parallel can be drawn 

 in this case with the extraordinary immigration that took place in 1879, for the 

 season that year was one of the most inclement ever known, and moreover, we have 

 not at present heard of immense migratory swarms on the continent, such as pre- 

 ceded the immigi-ation of the species into this country in 1879, and it is scarcely 

 necessary to say that in the early summer of this year (1892) the heat was sometimes 

 almost tropical. The swarm of V. cardui in 1879 was abnormal, both in amount 

 and in the conditions under which it occurred. Colias Edusa has appeared in some 

 numbers, and widely spread ; almost every active collector has seen or taken it near 

 London, and we have heard of it from far west in the south of England. The 

 hosts oi Plusia gamma seem to us to have been certainly immigrants for the most 

 part ; the somewhat numerous captures of Deiopeia pulchella may probably be 

 placed in the same category, with some others. 



In other Orders there has been no lack of proof that an unusually high tem- 

 perature is conducive not only to immigration, but also to abundance, and, in some 

 cases, to premature development. 



At the time of writing this note we are disagi'eeably reminded that a great 

 change has taken place. From a nearly tropical temperature we have plunged 

 almost into winter again, and several degrees of frost have been registered in the 

 south of England. It remains to be proved in how far the " promise of spring" 

 will be realized in autumn, and we look forward to the result with considerable 

 interest, more especially as regards Colias Edusa. — Eds.
