A paper by Mr. Hewitson was then read, containing descriptions of some new Pa- 

 pilionidas, of which the following is an abstract. The paper is accompanied by two 

 coloured Plates. 



" Many of our true Papilios which have now separate names, will, I believe, if 

 better known, prove to be only sexually and not specifically distinct. 



" Papilio Tullus proves to be the female of P. Sesostris. 



" Papilio Proteus and Areas, are male and female ; and I have no doubt that P. 

 Pirithous is the $ of P. Lycophron, and P. Acamas the J of P. Thersites." 



Papilio Bolivar. 



Allied to P. Yertumnus. Anterior wings deep black, with an irregular silvery 

 green patch, from the inner margin to near the middle of the wing : posterior 

 wings black, with a dark crimson patch at the lower half of the cell.
