ENTOMOLOGY. 



observed in a Papilio denominated by the continental entomologists 

 Papilio Hectorides, a fine and very striking object in the cabinet of 

 M. Gerning of Frankfort, and of which we also possess an elegant 

 example, a subject intended in our mind to appear in a future plate, 

 in order to render the characters of Papilio Latreillii more expHcit. 

 The insect alluded to will be found, on comparison, materially 

 different, notwithstandiug its similarity in this particular : the white 

 spot on the under wings is placed considerably lower, in the present 

 insect, being situated posterior to the middle of the disk, while in 

 " Hectorides it is central, or rather anterior to the middle. The 

 insect is also altogether smaller, and besides having the red spots on 

 the lower wings disposed in another manner, the first pair of wings 

 are crossed in the middle with a white list or band, as well above as 

 beneath, no trace of which is perceptible in Papilio Latreilii.
