172 , Report on 



Of this division we have 43 species recorded from this 

 district out of the 64 known British species. We have also 

 records of three others, which we prefer to call doubtful until 

 their occurrence has been verified, ist, Leiicophasia sinapis 

 (the wood white), which is recorded as having been seen on 

 the higher part of Riddlesdown, where it might be looked for. 

 2nd, Melitcea arteniis (the greasy frittillary), which is recorded 

 from Sandwich, Kent, rather beyond our limit. 3rd, Apatnra 

 iris (the purple emperor), a specimen of which is recorded as 

 having been seen. It was flying round the tops of some oak 

 trees at Selsdon in the year 1S74. As it was seen at the same 

 time by an experienced entomologist, who endorsed the 

 opinion, we feel that we are justified in recording this fine 

 insect. 



Of the 43 species actually authenticated, Pieris brassicce is 

 noticed by many to have become much less common than 

 formerly. Colias edusa and C hyale are remarkable for their 

 erratic appearances, being abundant in some localities in some 

 years, and extremely rare at others. Of the genus Arf^ynnis, 

 we have all the six species recorded in our district, although 

 one, A. Lathonia, is entered as being recorded by Newman in 

 August, 1868. We have a variety of A. Selene recorded by 

 one of our members. We have also all the Vanessas recorded, 

 although the rare V. antiopa has not fallen to the lot of any ot 

 our committee, still the record is good, and no doubt this was 

 one of its former haunts, being near the Camberwell district. 

 V. Cardui (another erratic) is recorded as being very abundant 

 in 1877. We have records of only two specimens of Argi 

 galathea, and they are from Reigate. Of the genus Satyrus 

 we again have all six species, S. Seiiiele being very common at 

 Riddlesdown. The hair streaks are well represented, and may 

 be looked for in the Croham and Selsdon district, whence we 

 have recorded rnbi, quercus and IV. album ; of the blues, 

 LyccEua, we have six out of a possible eight, L. acis and L. 

 arion, being absent. L. corydon is confined entirely to the 

 chalk, and is abundant at Riddlesdown. L. Alsiis is recorded 

 from the same place, and L. Argiolus frequents ivy, near 

 which it is often taken. Of the Hesperida, skippers, we have 

 five out of a possible seven, the best being H. comma, which 

 is recorded as sometimes occurring in great abundance at ■ 

 Reigate and Box Hill. The unrecorded species are H. linea 

 and H. acteon.
