One asks oneself what was the cause of the increase in the 

 captures on 19th and 20th ; the temperature gives no clue, the 

 amount of darkness increased, but it was the same on the 21st 

 when the numbers fell. 



From these tables it appears that the hours of darkness have 

 some effect, the temperature during the summer months at any 

 rate little or none.

NOTES AND OBSERVATIONS.

 Chichester for several days I noticed two specimens of Euchhe 

 cardamines on September 13th, and succeeded in taking one, a male, 

 near Boxgrove Priory." — Joseph Anderson ; Chichester. 



COLIAS CROCEUS AB. FAILL.3E AND HERSE CONVOLVULI IN LINCOLN-

 house I took a specimen in excellent condition of Colias croceus ab. 

 faillae Stef. I see the late Mr. Eowland Brown refers to this 

 aberration as follows : " Often occurs near Florence and is no doubt 

 widely distributed elsewhere." It would be interesting to learn 

 whether any other captures have been made this year in England. 

 On the day previous to this my neighbour brought me a large moth 

 that he had found at rest in his garden frame ; on examination it 

 proved to be Herse convolvuli in good condition. — G. T. Pigott 

 (Major) ; Somerby, Barnetby, Lincolnshire. 



Colias croceus at Plymouth. — Colias croceus was plentiful at 

 the end of August near Plymouth. I saw quite thirty one morning 

 in the limestone quarries at Pomphlett, and was fortunate enough to 

 note two var. helice, one of which I took. I also captured a female
