CONCHOLOGY. 



his description, not from the specimen itself, but from the drawings 

 of Mr. Jones, of Chelsea, which had been copied from the specimen 

 in the cabinet of Mr. Francillon, and it was to the drawing therefore 

 of Mr. Jones, and not to the specimen of Mr. Francillon's cabinet 

 that Fabricius annexed the name of Pylades. Those drawings must 

 for this reason be now considered as the only positive memorial of the 

 identity of the Fabrician species, Papilio Pylades, that remains extant 

 at this time. The figures, it may be added, which are submitted in 

 the annexed plate, are faithful copies from the original drawings of 

 Mr. Jones, so inscribed in the hand writing of Fabricius, a circum- 

 stance that must remove every shade of doubt as to the individual 

 object to which Fabricius had assigned that appellation. 



Papilio Pylades is a species of the Butterfly tribe, of moderate 

 size, in comparison with the generality of those which appertain to 

 the same family, the EquUes Achivi of Fabricius. The upper sur- 

 face exhibits an appearance of much simplicity and elegance : the 

 disk is white, and the broad black limb, or border, by which it is 

 surrounded, is marked with a number of spots and semilunar marks 

 of white disposed with much regularity. The disk of the lower sur- 

 face is also white, but surrounded with a pale brown, or fulvous 

 limb, and marked with white spots in the same manner as the broad 

 black border on the upper surface. A few of the white spots on this 

 fulvous border are surrounded by black lines and spaces. There is 

 also a red band marked with black and blueish spots, that extends 

 along the main or anterior rib of the upper wings, from the base, as 

 far as the middle of the wing, and a spot of red at the base of the 

 posterior pair.
