ENTOMOLOGY 



The wings of all the Papilios and Pbalasnas alread j 

 discovered are composed of a membranaceous or transparent 

 skin, extended between the tendons, or sinews ; these are 

 generally covered with small feathers of different shapes and 

 colours, which present, when rubbed off, to the powers of 

 the microscope, a most curious object, being plaecd over 

 each other like the tiles of a house. When these are only 

 inserted on certain parts of the wing, the rest appear 

 transparent, similar to those of the common fly. The 

 present moth is from a fine specimen in Mr. Bullock's 

 collection, and is a male insect, the female is possessed of 

 wings one inch larger in length and breadth ; although this 

 observation of the superior size is not always a certain 

 Criterion, as in some few species nature varies from that 

 rule. The under wings are ornamented by a beautiful 

 chain-border, the upper wings consist of red and black 

 streaks at each extremity, the space chiefly occupied with 

 undulated dashes of black and brown, the antenna? are 

 short and plain, and the whole presents to the view the true 

 character of the Simplex Munditiis of Horace, which, if 

 it could possibly be translated, might be denominated, ele- 

 gance joined with neatness.
