PLATE XXXVII, 



Few species of the Papilio tribe present an appearance more 

 extraordinary than P. Enothrea. This is an insect of the middle 

 size, having the margins of the wings pretty deeply Indented ; the 

 colour a deep fuscous with the disk green : the green forming a 

 broad common band across all the wings. Towards the tip of the 

 anterior wings is a series of lunate spots which forms a kind of 

 boundary line to the green disk of the anterior wings, and a series of 

 five larger spots of the same black colour on the posterior edge of 

 the green disk of the lower wings. There is also a series of somewhat 

 incurvate lines midway between that series of spots and the posterior 

 margin. Beneath, the prevailing colour is blackish, without any 

 shade of green, and is marked with a few obscure sagittate spots, 

 and a white dot on the ribs. 



This remarkable Insect inhabits Sierra Leone. 



These two curious Insects are displayed in the annexed plate in 

 the attitude of resting, with the wings expanded, upon a sprig of the 



BROWALLIA ELATA, THE UPRIGHT BROWALLIA, 

 a variety with violet coloured flowers, that inhabits Peru. 



It need scarcely be observed in addition that most species of the 

 PaplHo tribe, at the moment they rest from flight, appear with the 

 wings expanded, but that having placed themselves securely by the 

 assistance of their feet upon the plant, or any other body upon 

 which they alight, they throw their wings up in an erect position. 

 There are very few of the Butterfly tribe that do not appear to most 

 advantage when the wings are expanded, and it is for this reason that 

 the artist is almost invariably disposed to represent these insects
