THE ENTOMOtOGIST. 141 



the 14th of April. They began to fly between five and six 

 o'clock p.m.; earlier in the afternoon two or three of them 

 were sitting on every oak-trunk. My companion and I were 

 much interested in watching the intelligent way in which the 

 males sought out the nearly-wingless females. We noticed 

 two males rising out of the brushwood, at a distance of at 

 least ten yards from where a female was sitting on a branch, 

 and going straight to her in a curious, hesitating sort of flight, 

 reminding us very much of the manner of a pointer-dog when 

 taking up a difficult " scent." In another instance I was 

 looking at a female crawling on a tree, when a male flew off" 

 another tree at a few yards distance, and, alighting close 

 beside her, copulation at once took place. In these and 

 other cases the males flew against the wind, and almost in a 

 straight line to the females; and we therefore concluded that 

 it was the sense of smell, or something very like it, that was 

 guiding them. It VNas certainly not sight. — Robert Service ;

W. Thomas. — Asthenia pygmcBana. — I have Asthenia 

 pygmaeana, my own capture, in my cabinet, and should be 

 most happy to show it to you or your correspondent Mr. 

 Thomas. — Charles Boden ; 127, Tooley Street, April 19,

Does Crocallis elitiguaria Hybernate? — Mr. Newman's 

 reply to Mr. E. Holton (Entom. ix. 88) would lead us to 

 infer that the larva of Crocallis elinguaria usually does 

 hybernate. Is not this a mistake? I never knew an 

 instance of this species hybernating in any other than 

 the egg state. — Geo. T. Porritt ; Huddersjield, April 5, 

 1876. 



■ Mr. Helton's notice of the hybernation of Cro- 

 callis elinguaria in the egg state (Entom. ix. 88) is in strict 

 conformity with my experience of that species. 1 have bred 

 the species four years from eggs deposited by captured 

 females. I have invariably found them hybernate in that 

 slate, and commence hatching the last week in February. 

 The hatching generally extends over a period of from three 

 to four weeks. — Thos. H. Hedtcorth ; Diinston, Gateshead,
