PAPILIO. 215 



form found in Central America ; there, however, it comes into contact with two other 

 forms, P. protesilaus and P. telesilaus, both southern types with a very wide range in 

 South America. It will be observed that we unite the Colombian P. archesilaus 

 with our Central- American insect. From specimens before us it seems included 

 within the limits of the variation of the more northern form. 



Regarding P. macrosilaus (for a long time only a MS. name in Boisduval's collec- 

 tion) a few words seem necessary. Gray first mentioned it in a published work as a 

 variety of P. protesilaus, associating it with a Honduras specimen, but with inade- 

 quate characters. Bates ascribed it to the form with fawn-coloured lunules subse- 

 quently described as P. telesilaus. Boisduval himself says that Daubenton's figure in 

 the * Planches Enluminees ' is a good representation of his P. macrosilaus, and this 

 certainly agrees with the Colombian insect ; he adds that his own specimen came from 

 Costa Rica. Under these circumstances P. macrosilaus has some claim to priority 

 over P '. penthesilaus ; but the uncertainty of its application makes it desirable that 

 P. penthesilaus, a name fully characterized, well figured, and located, should be 

 employed. 



We met with P. penthesilaus in some numbers in the low-lying forest-region of 

 Northern Vera Paz ; here it frequented the sandy banks of the forest streams. 



Females of all these forms are exceedingly rare. We have one, however, taken with 

 its male at Calobre in the State of Panama, from which it appears that there is no 

 material difference in the coloration of the sexes ; the female, however, has a slightly 

 ochraceous tint pervading the wings.

This is a common form in South America, extending over a large portion of the 

 hotter regions. It enters our fauna as far as the line of the Panama Railway, and our 

 examples from there agree as to size with those of Colombia, and are rather larger than 

 those found in more southern regions. Felder, in his description, fully entered into 

 the local variations of this form.
