ROUND THE CHESTER ELECTRIC LAMPS. 245 



A. leporina. — A few specimens were taken. 



Smerinthus Mice. — The honours of the season fell to a visitor, 

 Mr. Quinton, who captured a specimen of this addition to the 

 district list, at the end of June. 



S. ocellatus. — Common during the first three weeks of the 

 month. On the night of the 5th no less than five were on the 

 ground at the same time, and within five or six paces of the 

 same lamp. Three of them were captured, and the remaining 

 two escaped. 



S. populi.—I did not observe this species until the 14th. It 

 was often flying round the same lamp in company with S. ocel- 

 latus. This fact, together with the non-union of two species so 

 like each other in size and general appearance, is, I think, very 

 significant. The same observation applies to other species ; for 

 example, A. badiata and A. derivata. 



Chosrocampa elpenor. — One taken, June 7th. 



Notodonta dictcea. — Fairly common, but they had to be 

 worked for. A collector might, up to the middle of the month, 

 have taken, on an average, one or two per night. Netting would 

 begin, in these long days, at 11.15 p.m. The round of lamps 

 would be worked, and then the return made for moths at rest. 

 This would take up to 2 a.m. or 2.30 next morning, when the 

 great luminary would rise in the east, and the electric lamps 

 would blanch and grow pale before it. 



N. dictceoides. — A few, I am told, but very few, were captured. 



N. ziczac.— Fairly common. 



Dasychira pudibunda. — A few were taken. 



D. bifida. — This good and handsome moth was a common 

 visitor. 



D. vinula. — Very common. 



D. furcula. — Occasional. 



Habrostola triplasia. — A fine-looking, dark moth, and fairly 

 plentiful. There was a handsome form with the basal outward- 

 bent line, and the outer-marginal inward-bent line, almost 

 scarlet.
