scribed and figured by Savigny in his Memoires sur les Animuux suns 
Vertebras, Paris, 1810.), with palpi, a spiral tongue; the body covered 
with hair. The scales resemble feathers : they be over one another in 
an imbricated manner, the shaft towards the body of the insect and the 
expansion towards the end of the wing, reflecting the most brilliant co- 
lours. „ 
Genus 51, Papii.io. 
Antenn* clavate, gradually thickening towards their extremist mngs 
when at. rest erect and meeting upwards. Alt tlie insects ol this ge- 
nns fly in the day-time. , 
Linne in a peculiar and instructive manner divided this beautiful 
and numerous tribe into sections, instituted from the habit or general 
appearance, and in some degree from die distribution oi the colour ot 
the wings.

This is an insect of great beauty, and may be considered as tl.c onlv 
British species of Papilio. It is well known to collectors by the title ot 
the Swallow-tailed butterfly, and is of a beautiful yellow, with black 
spots or patches along the upper edge of the superior wings; all the 
win-s are bordered with a deep edging oi black, decorated by a double 
row of crescent-shaped spots, of which the upper row is blue and the 
] ower yellow. The under wings are tailed, and are marked at the in- 
ner aivde or tip with a round reel spot bordered with blue and black. 
The larva of this species feeds on fennel and other umbelliferous 
plants. It is of a green colour encircled with numerous black bands 
spotted with red, and is furnished on the top of the head with a pair ol 
short trntacula of a red colour. In the month of July it changes into 
the chrysalis or pupa stale, fixed to some part of the plant on which it 
feeds and in the month of August the perfect insect appears. It fre- 
quently happens that two broods of this butterfly are produced in the 
same summer ; one in May, having been in the pupa state all the winter, 
the other in August from the pupa of July. {PI. O.fg. 1.)

palpi two : whig* deflected.

sects. They flyvery swift, for theinostpart early in the morningand 
late iii the evening, some of the smaller species during the day.
