3350 Insects. 



bourhood. Solitary examples of insects away from their native soil, 

 have occasionally occurred I believe in most counties. 



In September last, while partridge-shooting in a field of standing 

 barley, near to Biggin Hall, I observed a single specimen of Colias 

 Edusa. Two coveys of birds were marked down in the barley, and 

 immediately over them the Edusa was slowly and majestically taking 

 its flight. Had I not been in company with other sportsmen, compa- 

 rative strangers to me, I believe my entomological propensities would 

 have gained the ascendancy over my sporting ones ; for I certainly 

 felt a very strcmg inclination to hand over my gun to the keeper, and 

 spring the coveys for the chance of capturing the fly : however, as 

 matters stood, the partridges were to suffer, and so the Edusa escaped. 



The great prize of all the butterflies of our neighbourhood, how- 

 ever, I hold to be Polyommatus Arion, which, if I mistake not, was 

 first discovered here by myself some thirteen or fourteen years since. 

 It is confined entirely, so far as my experience goes, to Barnwell 

 Wold, and the adjoining rough fields, with the exception of a single 

 specimen, which I once met with in a rough field near Polebrook. Its 

 flight is somewhat peculiar, being different from that of others of the 

 same genus, and more resembling that of Hipparchia Pamphilus and 

 Tithonus. Independently of its manner of flight and size, it is in 

 most instances easily distinguished on the wing from the other blues, 

 by its dark and irony appearance. Many entomologists have of late 

 years visited Barnwell Wold in search of Arion ; in short, a summer 

 never passes without meeting in my rambles with brother entomolo- 

 gists from distant parts of the country ; I rejoice, however, to be able 

 to state that its annual occurrence does not appear to be diminished 

 in consequence. Unless my memory fails me, I think Mr. Wolley, of 

 Trinity College, Cambridge, informed me that he one year captured 

 in a few days between fifty and sixty specimens, in and about Barn- 

 well Wold, though, in point of weather, the days were anything but 

 favourable. 



I may perhaps as well add, that I have heard of Papilio Machaon 

 having been seen here ; and it is by no means improbable, from our 

 vicinity to the fens of Whittlesea Mere, now, alas ! no more : a flight 

 of six or seven miles would easily cover the distance. 



Two specimens of Argynnis Lathonia are reported to have been 

 seen or taken in Ashton Wold ; and a few of L. Camilla in the woods 

 near Benefield : for the authenticity of these, hovevcr, I am not able 

 to vouch.
