 ■with hair. The scales resemble feathers : they lie over one another in 

 an iniljricated manner, the shaft towards the body of the insect and the 

 expansion towards the end of the \ving,reflecUng the most brilliant co-

Genus 51, Papilio. 



Antcm}^ clavatc, gradually thickening towards their extremity: wings 

 when at rest erect and meeting upwards. All the insects of this ge- 

 nus fly in the day-time. 



Linne in a peculiar and instructive manner divided this beautiful 

 and numerous tribe into sections, institutetl from the habit or general 

 appearance, and in some degree Irom the distribution of the colour of 

 the wings.

This is an insect of great beauty, and may be considered as the only 

 British species of Papilio. It is well known to collectors by the title of 

 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 

 wings are bordered with a deep edging of black, decorated by a double 

 row of crescent-shaped spots, of which the upper row is blue and the 

 lower yellow. The imder wings arc tailed, and are marked at the in- 

 ner angle or tij) with a round red 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 nun)crous black bands 

 spotted with red, and is furnished on the top of the head with a pair oi" 

 short teutacula of a red colour. In the month of July it changes into 

 the chrysalis or pupa state, fixed to some part of the plant on which it 

 feeds, and in the montli of August the perfect insect appears. It fre- 

 quently happens that two broods of this butterfly arc produced in the 

 same summer; one in May, having been in the [lupa state all the winter, 

 the other in August from the pupa of July. {PI. O.f'g. 1.)

Antcnim attenuated at each end : tongue in most species stretched out : 



palpi two: rw«gs deflected. 



Some of the species of this genus are the largest of lepidoptcrous in- 

 sects. They fly very swift, for the most part early in the morning and 

 late in the evening, some of the smaller species during the da}'.
