common on the chalk, but scarce here. — 1913. Eemarkably scarce 

 and late ; not seen at all by me until June 13th at Oxted, and then 

 by no means common ; and Mr. Gillett tells me he only observed 

 the species a few days earlier near his house on the N. Downs, a few 

 miles further east. The second brood has, however, been abundant 

 on the N. Downs, but by no means common hereabouts. 



L. corydon. — 1912. Two males, July 13th, near Otford ; females 

 egg-laying near Oxted, September 7th. — 1913. Both sexes, only 

 moderately common, near Oxted, August 14th. 



Cyaniris argiolus. — 1912. Some six or eight years ago this 

 butterfly was by no means common hereabouts, in spite of the 

 abundance of holly throughout the woods. Latterly, however, it has 

 appeared in profusion, and even the adverse season of 1912, so 

 detrimental to many species, seems to have affected this one less 

 than most. From April 18th, when I record the first, a male, argiolus 

 was abundant everywhere about these hills ; rather less so on the 

 chalk. There, where holly is rare or absent, probably Gornus san- 

 guined is one of the principal food-plants of the early brood of larvae. 

 On May 9th I saw a female lay one egg on an immature flower 

 umbel of this shrub just beneath a bud, and larvae subsequently fed 

 on the petals and unripe berries, rejecting calyx or leaves. It may 

 be of interest to note that near Boscastle, late in June, being unable 

 to find dogwood thereabouts, immature berries of privet and elder 

 were offered the larvae but rejected, they having to be fed up finally 

 on holly. The above-mentioned egg hatched in nine days and pro- 

 duced a butterfly on July 16th. Another egg was observed to be 

 laid at the base of the ovary of a holly-blossom on May 11th. The 

 last specimen I record of this brood was on June 9th, at rest upon a 

 fence. The second brood began to appear on July 13th, specimens 

 of which were less abundant than those of the earlier brood, but 

 still common. A larva was found on ivy-bloom as late as Sep- 

 tember 17th, producing a butterfly on April 17th of this year. — 

 1913. Although not nearly so abundant as last year, butterflies of 

 both broods have been far from rare. First appearance of first brood, 

 April 20th ; of the second, July 29th. A specimen in Kew Gardens, 

 August 20th. Larvae of the second brood have been unusually com- 

 mon on ivy in September last. 



Hesperia alveolus. — 1912. First appearance, April 27th. — 1913. 

 First appearance, May 21st. A perfectly fresh specimen was taken 

 at Mereworth as late as June 14th.
