CAPTURES ARD FIELD REPORTS. Il5^ 



Those found in the open to-day by my son were all very small. — 

 E. Sabine; The Villas, Erith, March 13th, 1902. 



Catalogue of the Lepidoptera of Ireland. — There are three 

 points I am sorry not to see touched upon in the review of this Cata- 

 logue (diite, p. 54). First, why Ccenonumpha typlioii occurs further 

 south in Ireland than in England, /'. e. why it should occur in the 

 Killarney district and not in the wilds of Dartmoor and Exmoor, in 

 Devonshire. Second, the occurrence of Bankia argentula both in the 

 English fen counties and in the west of Ireland, but not in the inter- 

 vening space. Third, why should our islands have been restocked 

 from the Continent since the climax of the Glacial Period ? One 

 question is, how long might the ova and pupae of insects remain 

 buried in the earth or in rubbish, beneath snow and ice ? If they can 

 do so for years, what occasion was there for our islands to be restocked ? 

 Another is, was not the greater part of Europe overwhelmed, as much 

 as our own islands ? What prevents our islands from being part of the 

 Arctic Kegions but the changeability of the winds ? Should the wind 

 blow uninterruptedly from the north-east for twelve months or more, 

 we shall again have a glacial period. — C. W. Dale ; Feb. 8th, 1902. 



CAPTURES AND FIELD REPORTS. 



CoLiAs HYALE NEAR Dartford IN 1902. — While out Collecting larvte 

 this morning, one of my sons saw a male of this species disporting 

 itself on the railway bank. It passed close by him several times, 

 apparently in good condition, its colour being very bright. I should 

 fancy this is a "record " early appearance. Are we to have a third 

 ht/ale year in succession? — E. Sabine ; Erith, March 13th, 1902. 



Thecla w-album and Colias edusa in Bristol District. — It might 

 interest some readers to know that T. w-album was very common last 

 year in certain favoured spots at Bristol, while in the season of 1900 

 it positively swarmed. In the latter year G. edusa was very abundant 

 in Leigh woods and neighbourhood. — M. J. L. Davis; Lyndhurst, 

 St. Ronnan's Avenue, Redland, Bristol. 



YoRKsmRE Dragonflies. — Mr. H. J. Burkill sends the following 

 notes on Yorkshire dragonflies : — "In the ' Entomologist ' for 

 February last Corduleyaster annulatus is reported for 1901, from York- 

 shire. I saw two insects of this species on Aug. 15th, 1901, in 

 Hayburn Wyke, a wooded ravine on the coast, six miles north of 

 Scarborough. Being unprovided with a net, I could do no more than 

 stalk them slowly, and on one occasion stood for nearly ten minutes 

 within five yards of one of the pair which was sunning itself on an 

 ash-trunk. I think there is no doubt as to the identity of the species, 

 the alternate yellow and dark bands being so very conspicuous. A 

 few miles further north, on Sept. 4th, 1899, I captured several 

 specimens of Synipetrum scoticum on the moors. This last year, in 

 June, I found Libellula depressa very abundant on the cliffs south of 

 Scarborough, together with Isclmura eler/ans and a few Agrion puella. 

 I might add that I picked up a dead male Caloptenjx virgo, in the road
