 INSECTS Polyommatus segon, Bork. Locally common on boggy heaths — agestis, Schiff. (medon, Esp. ; astrarche, Bgs.). Norwich, Hunstanton, Lynn, Merton, Thetford, Broom Heath — corydon, Fab. Abundant at Ringstead Downs ; found casually at Hunstanton, Lynn and Snettisham — argiolus, Linn. Cawston, Booton, Thetford, Broome and Gillingham ; but not common — alsus, Fab. (minima, St. C). Cromer and South Crcake, scarce ; but found plentifully near Swaffham by Mr. Atmore in 1898 — acis, Sch. (semiargus, St. C). Recorded in this county by Haworth and Stephens in the early parts of the century, but, as in other parts of England, long since extinct Apatura iris, Linn. Foulsham, Dersingham, but rare ; formerly at IVhitlingham ; not scarce in Foxley Wood Vanessa c.-album, Linn. Very rare in the county. The Rev. W. F. Welch informed Lord Walsingham that he saw a specimen in his garden at Stead- sett in October, 1858, and took one in the same place in September, 1861 ; the Rev. J. W. Colvin took one in the Rectory garden at Yarmouth ; and Mr. E. A. Atmore reports a specimen at Walpole — polychloros, Linn. Widely distributed and formerly common ; now very un- certain in appearance — antiopa, Linn. An occasional migrant. In 1872 it was suddenly observed quite commonly in the county, especially at its north-east corner, and a considerable number were taken. Within a few days the course of the migrating flock was traced in some degree across the county and onward until specimens reached scattered localities in the West of England. It has been recorded casually in the county so early as 1834, and in various other years to 1891 Argynnis paphia, Linn. Generally uncom- mon ; much more plentiful in Foxley Wood — aglaia, Linn. Almost confined to the east coast, but once found commonly at Whitesley — adippe, Linn. Local in the woods of the north and west of the county — lathonia, Linn. Excessively rare. I have seen a specimen which was taken at Plumstead, near Norwich ; others are recorded at Beechamwell, Halvergate^ Caistor and Booton Argynnis ^euphrosyne, Linn. Local in this county. Stratton Strawless, Horsford, Tindall Wood, Cawston, Runcton, Mid- dleton ; in woods — selene, Fab. Local in most of the same woods ; also at Hoveton St. jfohn, Hethel and Wootton Melitaea artemis. Fab. (aurinia, St. C). In marshy meadows ; very local. Nor- wich, St. Faiths, Horning, Cawston, Aldeby and Beachamwell Melanargia galathea, Linn. Found locally at Kirby Cane by Dr. W. M. Crow- foot, who also noticed that it moved from one spot to another almost every season. Recorded in Norfolk by Curtis Satyrus semele, Linn. Common on coast sandhills and inland heaths Pararge asgeria, Linn. Norwich, Merton, Thetford, Ditchingham, Sparham ; un- common in the county Epinephile tithonus, Linn. Abundant — hyperanthus, Linn. Plentiful in damp woods Syrichthus alveus, Hub. Several specimens were captured about twenty-five years ago in a damp hollow at the edge of a wood at Cawston, by the Rev. T. H. Marsh. These I found in his collec- tion under the name of the next species, to which he had referred them — the latter being apparently absent from that district. The locality has been carefully searched in many subsequent years, but no more specimens have been found. This species is scarcely known otherwise as British, and it is supposed that a small migration from the other side of the North Sea may have taken place, but without causing a permanent settlement — alveolus, Hb. Woodton, Tyndall Wood, Ditchingham, Ketteringham, Horning ; scarce and very local in the county Hesperia comma, Linn. Taken by Mr. Atmore, near Swaffham Cyclopides paniscus. Fab. A single specimen was taken near Thetford, in the presence of the Rev. H. Williams Nisoniades tages, Linn. Ditchingham, Ket- teringham, Cawston ; very local, yet re- corded in the county by Haworth and Stephens 139
