NOTES FROM WEST SUSSEX : LEPIDOPTEEA IN 1920. 49 



Aijlais urticae. — Not common. Fresh brood on July 24th. Worth- 

 ing, Sompting, Lancing, and Bramber. 



Gonepteryx rhamni. — Hybernated specimens first recorded on May 

 10th ; not uncommon in the vicinity of woods and heaths. I was 

 surprised not to see any of the fresh brood later in the season. 



Vanessa io. — May 14th. Scarce, only a few hybernated specimens 

 observed near Steyning and Goring. I saw nothing of the fresh 

 brood. 



Pyrameis cardui. — May 14th. Immigrant specimens were ex- 

 tremely plentiful in the spring and early summer, especially in that 

 part of the country embracing the Downs. The fresh brood, though 

 not quite so much in evidence, was also common, and put in an 

 appearance on July 19th. 



P. atalanta.—M&y 14th. Hybernated, or immigrant, specimens 

 fairly numerous, and met with in company with P. cardui, sunning 

 themselves on the roads, more frequently in the lanes leading up to 

 the Downs. The fresh brood, first noticed on July 19th, was also 

 rather common. 



Pararge megera. — First brood, May 14th ; second brood, August 

 3rd. Common, more particularly in Down-land and on the sandy 

 heaths north of the Downs. 



Hesperia malvae, — May 14th. An abundant species in many 

 localities. 



Pieris napi. — First brood, May 20th ; second brood, July 12th. 

 Common. 



Callophrys rubi.— May 20th. Sparingly met with near Clapham, 

 Angmering, Washington, and Edburton. 



Brenthis eitphrosyne. — May 20th. Locally common in several of 

 the woods both north and south of the Downs. On May 26th, in a 

 wood near Patching, I netted a fine $ aberration while it was settled 

 and sunning itself on the ground. The forewings of this specimen are 

 edged along the outer and inner margins with a blackish suffusion, the 

 four basal markings coalesce and make a large, solid, black patch, 

 while the zigzag series of spots, beyond the black marking at the end 

 of the discal cell, are confluent, forming an irregular and broadish 

 band across the middle of the wing ; the basal markings on the hind- 

 wings are, also, strongly marked and confluent, but clearly defined 

 without any suffusion of black scales. 



Eumicia phlaeas. — First brood, May 21st ; second brood, July 16th. 

 Not uncommon. I took two interesting specimens: (i.) A ? , on June 

 1st, near Clapham, which may be described as ab. radiata-caeruleo- 

 punctata, as it combines both these named forms ; and (ii.) a ? , on 

 August 17th, near Storrington, which has the outer part of the copper- 

 colouring on the right forewing bleached, while the submarginal spots 

 on both forewings are rather elongate. Ab. caeruleopunctata was not 

 uncommon in the district. 



Aricia medon. — First brood, May 21st ; second brood, July 24th. 

 Clapham, Lancing, and Edburton. Not so common as one might 

 have expected considering the abundance of its food plant, Relianthe- 

 vnun chamaecisius. 



Coenonympha pamphilus, — May 21st. Common throughout the 

 district. 



Nisoniades tages. — May 21st. Plentiful in many localities on, or
