 INSECTS The Wood White ^ [Leucophasia sinapis, L.) used to occur in abundance in Whittlebury Forest, and in Geddington Chase, Plane Woods, Sywell Wood, and Yardley Chase ; also near Towcester and elsewhere in the county, but it has not been observed lately. The Black-veined White {Pieris cratcegi, L.) formerly occurred near Peterborough, in Barnwell Wold, and also on the borders of the county between Thurning and Gidding Magna in Huntingdonshire ; but it seems to be now extinct, as it has been in most other English and Welsh counties for some years past. The writer looked for it in vain between Thurning and Gidding for many weeks nearly thirty years ago. The Clouded Yellow {Colias edusa. Fab.) occurs occasionally and was abundant in the county in 1878, 1892 and 1900, and in the latter year the Pale Clouded Yellow (C. hyale, L.) also occurred. The three large Fritillaries [Argynnis paphia, L., A. adippe, L., and A. aglaia^ L.) are commonly distributed throughout the woodlands, and A. paphia is often abundant in Salcey Forest, Whittlebury Forest and other wooded parts of the county. The Queen of Spain Fritillary {Argynms lathonia, L.) has been recorded from the county by Messrs. Hull and Tomalin. The Pearl-bordered Fritillary [Argynms euphrosyne, L.) and the Small Pearl-bordered Fritillary {A. selene, SchifF.) both occur in the county, and the former is common in most of the woods. The latter is more local, but it has been recorded from Waddenham and Towcester. The Greasy Fritillary [Melitcea artemis. Fab.) — always very local — used to be found at Aldwinkle near Waddenham, near Towcester, and near Barnwell, but no recent captures have been recorded. The Comma Butterfly [Vanessa c.-album, L.) so abundant in favourable seasons in certain west-midland counties and other parts of the west and north of England, and in some Welsh counties, occurs in this county, and the writer has taken it near Oundle. It has also been taken near Waddenham, Towcester, Yardley Chase, Sywell Wood, Lilford, Barnwell Wold and Northampton. Mr. W. Edwards records it as frequent near Lilford on ivy-bloom at the end of September. The Large Tortoiseshell [Vanessa polychloros, L.) is recorded from Salcey Forest, Towcester and Barnwell Wold ; and also from Geddington Chase, Weekly Hall Wood, and elsewhere near Kettering. The very rare Camberwell Beauty [Vanessa antiopa, L.) has been taken near Kettering, at Thurning, in Whittlebury Forest, at WeUing- borough, and twice at Northampton. The White Admiral [Limenitis sibylla, L.) was recorded by the late Mr. Bond as occurring near Waddenham ; Messrs. Hull and Tomalin mention Sywell Wood and Lilford as locaUties for it, and Mr. G. C. Druce informs me that he saw a specimen recently near Brackley. The Purple Emperor [Apatura iris, L.) occurs commonly in the great oak woods in the neighbourhood of Rockingham, Kettering, 1 The present occurrence of Leucophaiia linapii and Melitea artitmis in the county seems to require confirmation. — H.
