 rare 4 . 



P. lycidas may readily be distinguished from all members of this section of Papilio 

 by the yellow abdominal fold of the hind wings. The primaries are more elongated 

 and pointed than those of other species of our region.

Mr. Bates determined specimens obtained by us in Guatemala 3 to be identical with 

 P. numitor of Cramer, a butterfly of Surinam. We have always considered this identi- 

 fication to be correct, and this is still our opinion, though Cramer's figure is not at all 

 a satisfactory one, the band of spots on the secondaries being unusually small. As 

 regards the range of the species, the wide gap between Guatemala and Guiana is now 

 found to be in a great measure filled up by the extension of the Central- American 

 insect to Costa Rica, and its reappearance in Colombia and Venezuela in precisely 

 similar form and colour. Specimens from the last-named countries were described by 

 Pelder as P. latinus, a name which, if Mr. Bates's determination is correct, becomes a 

 synonym of P. numitor. Like all other members of this group of Papilio it frequents 

 the forest of the low-lying districts, its range in altitude probably not exceeding 

 5000 feet.
