uelle writes : " It is very local, but occurs at Beverley in Yorkshire, and near 

 Bristol, and has been taken in Hampshire, near the New Forest." 



In her " Butterfly Collection's Vade Mecum," published in 1827, Miss 

 Jermyn only gives the following localties for Machaon — Fenny Places, Acle, 

 and Horning, Norfolk ; Cherry-Hinton, Madingley, Whittlesea, and Grand- 

 chester, Cambridgeshire.'" 



In 1841, three specimens of Machaon were taken by three different col- 

 lectors at Haverhill, Suffolk. 



In 1856, George Austin writes in the " Entomologists' Weekly Intelli- 

 gencer," I have been accustomed to find the larvse of Machaon year after 

 year in the osier beds, behind Beaufroy's Distillery in Battersea Fields, but 

 never once detected it in the winged state." 



In 1871, Newman in his "British Butterflies," writes, "I have repeatedly 

 found the caterpillar feeding on rue in a garden, on Tottenham Green j tins 

 was probably fifty years ago. It can now only be sought for, with any pros- 

 pect of success, in the counties of Cambridgeshire, Huntingdonshire, Norfolk, 

 and perhaps Suffolk. In the "Young Naturalist," for 1879, we read " Ln 

 England, Machaon is a fen insect. It was formerly common in all the Nor- 

 folk and Cambridgeshire fens, and then occasionally visited gardens in the 

 suburbs of London. Now it is almost, if not entirely, confined to Wicken 

 Fen, in Cambridgeshire." 



Departed friend, alas, good-bye, 

 Wilt thou Wicken too forsake ? 

 In Dorset, Somerset, Yorkshire, Kent, 

 We mourn thy loss — 

 Yea, regret it, 



PAPILIO PODALIRIUS. 

 Scarce Swallow-tailed Butterfly. 



Podalirius, Linn. Podalirius, brother to Machaon. 



The wings are pale yellow, with black transverse bands, the intermediate 

 ones on the fore wings shorter ; hind wings with a black border marked 

 with several blue crescents. They have also a long tail, and the eye-like spot 

 at the anal angle of the hind wings is orange in front, and black, dusted 

 with blue, behind. They expand from 2| to 3| inches. 



The caterpillar is thick, shaped somewhat like a woodlouse, and contracted 

 behind. It is green, with yellow lines on the back and sides, and with yellow 

 transverse lines spotted with red. It feeds on almond, sloe, plum, apple, 

 pear, and oak. 



The chrysalis is shorter than that of Machaon, and stouter in proportion, 

 more decidedly bifid at the head, and more pointed at the tail. In colour it 

 is ochreous, with darker streaks,
