CAPTUEES AND FIELD REPORTS. 91 



Satynis egeria. From April 19th, throughout the season, very common 

 iu the island. I think that this species must undoubtedly hybernate, both 

 as larva and pupa. In a wood which I was in the habit of visiting daily, 

 it was noticeable that after the examples of the first spring emergence had 

 become decidedly and pretty uniformly worn, a new supply of what were 

 obviously freshly-disclosed specimens presented themselves towards the 

 end of May. 



S. 7neg(Bra. From May 11th; both broods in abundance. Larvae from 

 ova laid on Aug. 13th are now hybernating ; they have never entirely 

 ceased feeding during the whole of the mild winter which we are at present 

 experiencing. 



S. semele. This species was already abundant in South Devon by June 

 27th. I had not seen it in the Isle of Wight previous to this date, where 

 it abounded later on in the season. 



S. ianira. From June 6th. No bleached specimens seen last season. 



S. tithonns. From June 27th, in abundance, till Aug. 30th. 



S. hyperanthes. From June 30th till Aug. 7th. This butterfly always 

 seems to be for a much shorter time on the wing than any of the other 

 single-brooded Satyrs. This seems rather to point to the probability of the 

 larvae being more nearly of the same age previous to hybernation. 



Ccenonympha pamphilus. First appearance, May 8ih. 



Thecla rubi. From May 9Lh (Isle of Wight) tillJuly 11th (S. Devon). 



T. quercus. Very abundant at Parkhurst in July and August. 



Polyommatus phlceas. From May 9th till Oct. 17th. On Sept. 29th 

 some females were seen, busily engaged in depositing their ova on dwarf 

 plants of Rumex acetosella. On examination a profusion of ova were 

 discovered on them. This plant is so hardy, even in severe winters, that 

 probably it affords the most suitable resting-place for the winter larvae of 

 P. phlceas, which hybernate at different ages, and feed in mild weather. 



LyccBna agon. Not observed in the Isle of Wight. By June 29th in 

 abundance on the South Devon coast. 



L. agestis. Very few of the first brood seen ; the second brood in fair 

 numbers, both in South Devon and Isle of Wight. 



L. alexis. From May 12lh, in abundance. An interesting variety of 

 the under side of a male was procured near Atherfield, Isle of Wight. In 

 it the normal fawn ground-tint is completely usurped by pure white, the 

 former being restricted to a few slashes along the base of the wing-rays, 

 the spots on the fore wings being prolonged into broad dashes. 



L. adonis. Of the first brood of this species I was unable to find any 

 examples, although, wishing to procure some for a friend, special search 

 was made for it, and that in known localities. In August, however, it 

 turned up abundantly, being specially common near Carisbrooke ; also 

 being found near Ventnor, near Mottistone, and sparingly on the Fresh- 

 water downs. 



L. corydon. By July 22nd abundant in the island, often in profusion, 

 till the end of August. The bulk of the males appear before the females 

 are visible. Specimens of the latter, with the spots on the fore wing under 

 side coalescing into horizontal bars, not rare, frequently occurring on one 

 side only. 



L. alsus. Sparingly near Carisbrooke and on the Undercliff. Although 

 out on May 27th, I met with a solitary fresh specimen on July 22nd. 



L. argiolus. A solitary specimen of the first brood seen, but in the 

 first huh of August common, locally, at Carisbrooke ; also about the
