﻿228 THE ENTOMOLOGIST. 



in summer the haunt of the nightjar and many warblers ; and in 

 winter a hiding-place for the majority of our species of ducks. 

 Lyccena corydon could then be taken here, and Aporia cratcegi 

 was common in Elm Grove. (Vide a paper read by Mr. H. 

 Moncreaff before the P. and G. Natural Science Society.) 



The wall was demolished nearly twenty years ago ; of the 

 ferns I have only found three species on the island. Southsea 

 has become a well-known watering-place, and Landport the 

 busiest part of the town. The rabbits have a feeble hold on the 

 north of the island; hares are very scarce; the nightjar I have 

 never seen or heard here. L. corydon occurs very sparingly on 

 Portsdown Hill, and A. cratcegi has been extinct for twenty years. 



My notes are taken from a list of the fauna of the district, 

 compiled by myself and members of the Portsmouth and Gosport 

 Natural Science Society. The district proper is the whole of the 

 land south of Portsdown Hill, enclosed by parallel lines drawn 

 from the east and west ends to the shore ; but I shall not confine 

 myself strictly to these limits, as very little has been written on 

 the insects peculiar to this district. 



The Rhopalocera are divided among the several families, as 

 follows : — Pieridse, 8 species ; Nymphalidse, 13 ; Apaturidse, 1 ; 

 Satyridse, 8 ; Lycsenidse, 10 ; Erycinidse, 1 ; , Hesperiidse, 5 : 

 total, 46 species. Two of them are now extinct, thus reducing 

 the total to 44 species, all of which are to be found within ten 

 miles of Portsmouth Town Hall. 



PlEBID^E. 



Aporia cratcegi. — Once common in Elm Grove, Southsea, but has now 

 been extinct for about twenty years. 



Pieris brassier. — Common. In the evening of August 8th, 1887, in 

 Alder Marsh, near Gosport, Mr. T. H. Larcom and myself stood on one 

 spot, and without moving counted, within a space of not more than six 

 square feet, over two dozen (I believe it was twenty-nine) specimens of this 

 species and P. rapce, which were resting for the night on the bramble 

 bushes. A few days previously I counted over fifty white butterflies in the 

 Bury Koad ; they were, no doubt, a portion of the swarm that visited the 

 southern counties during the autumn of that year. The larvae of P. brassicce 

 and P. rapes were very numerous in October and November, 1888, at 

 Gosport. P. rapce. — Quite as common as P. brassicce. P.napi. — Common, 

 but rarely so common as brassier and rapce. P. daplidice. — Portsdown Hill 

 is the only locality in the district where this insect has been taken. Mr. 

 J. J. Moore took two specimens here; Mr. H. Moncreaff, one; Mr. Taylor, 

 one ; a fifth is said to have been taken by another collector ; and a sixth 

 was seen by Mr. Larcom and myself on some chalky ground, August 22nd, 

 1886. I am unable to obtain the dates of the above captures, but none are 

 very recent. 



Euchlo'e cardamines. — Generally common throughout the district. I 

 have several specimens with the inner margin sulphur-yellow. A few years 

 ago Mr. Larcom obtained a male with an orange blotch on the under wing 

 near the hind margin ; so far as I can discover it is not a pupal stain.
