ADAPTABILITY TO CLIMATIC ENVIRONMENT. 208 



the Klaphrus, it only comes out when the sun shines and is exceedingly 

 rapid in its movements. In moss on the mountains and of the sides of 

 waterfalls occurred Leateva sharpi and L. pubescens, Homalnta silvicola, 

 H . obloiujiiiscida and H. eremita^Ocijin^a incrassata , A rpedium brachypterum, 

 Gymnusa variegata, etc. The very rare Brynporus ru/ipennis and 

 Mycetoporiis monticola were taken by me on Ben-na-buird nearly 4000 

 feet up. 



Melanic forms of the following species were found — Lesteva longely- 

 trata (with quite black legs), Klaphrus lapponicus, Anchomenns ericeti and 

 A. parutn}iunctatns, Corymbites aerw/inosiis (nearly black <J), Tacliinxs 

 subterraneus, Pterosticliiia vitreus, Carabiis arrensis, Amara lunicollis, and 

 Phratora vitelUnae. 



In the river bed of the Dee we took Coccinella 5-punctata and 

 Crypto/iypnus maritimus, a very agile and difficult species to catch, 

 occurring in numbers on the boulders, a new record, I believe, for the 

 Dee. It flies in the sun, runs as fast as a tiger beetle with its long 

 legs, and " skips " oif the large stones into the shingle. In a sand-pit 

 Tachinus eloncfatus, Byrrhus dorsalia (very finely marked), Barynotiis 

 schdnherri (abundant), Erirhinus aetliiops, and Phyllotreta fiexuoHa 

 occurred. Sweeping for the two latter in a marsh near was successful, 

 a series of each being taken. 



Geodroniicus nigrita was captured on the wing, one specimen being 

 taken from the clutches of a predaceous Dipteron. Philonthus puella 

 in deer and cow dung, chiefly in the latter. 



Gonioctena pallida was abundant on hazel and sallows, Dorytvinus 

 tiulaciniis being also common on bushes of the latter. 



Beating fir-tops produced Eros aurora, Ernohius niyrinus, Crypto- 

 p/iayus eylindrus, Tomicus bidentatus, T. quadridensy etc. 



ZeiKjophora turneri was very scarce on aspens, the beetle evidently 

 not being on, as it should occur in numbers. Several specimens of 

 Epuraea silacea were taken on birch stumps, and Ayathidium rliinoceros 

 scarce in the woods. 



A fine variety of Coccinella hieroylyphica was found on a patch of 

 Sphaynum, the shoulder-marks being confluent in two semicircles. 

 Silpha opaca and S. niyrita were picked upon the roads, one of the latter 

 being infested with an enormous stout intestinal worm, very many 

 times longer than the beetle. Several specimens of Patrobus crcaratus 

 taken in a sand-pit were also infested with a smaller and thinner worm. 

 I hope to visit Braemar again ; the air, beautiful scenery, and moun- 

 tains well stocked wir.h deer, apart from the insects to be found, make 

 it an ideal place in which to spend a holiday. 



Differences of adaptability to climatic environment in certain 

 Nearctic Papilionids. 



By CECIL FLOERSHEIM, B.A., F.E.S. 

 I have been much struck during the past few years by the great 

 dift'erences in adaptability to climatic environment shown by the 

 various kinds of Nearctic Papilionids I have bred in my butterfly- 

 house. Indeed, the species which I should have thought most likely 

 to become single-brooded in England has remained persistently double- 

 brooded at least, whilst that which I thought I should stand verj* little 

 chance of restraining from its habit of producmg several generations
