fornian examples the wings are also broader than in the eastern 

 ones, but there is not that wide aberrancy that marks in a 

 moment the above-described New Mexican form. 



The largest examples of Philenor that I have seen were from 

 Ohio, Pennsylvania and New York, whilst the smallest were 

 from Georgia, and especially Florida, where, to the contrary, 

 another of our species, the well-known Tarnus, is found of 

 large and frequently enormous size. The Californian examples 

 of Philenor are small, or, at most, only of medium size. 



Papilio Cleombrotus. 



Expands 3 j inches. Head and body black ; on head are two 

 obscure yellowish spots, two more on the collar, and one on 

 each shoulder. Abdomen with yellow lateral stripes. 



Primaries narrow. 



Upper surface black, with greenish blue sheen on basal third ; 

 a large yellow central spot, partly within the median cell, and 

 partly outside the median nervure. Fringes on upper half 

 outer margin black, on inner half black and white. 



Secondaries rounded outwardly, outer margin dentated. Deep 

 shining greenish blue, except along the costa, where the blue 

 shades into or is replaced by black ; a row of small white sub- 

 marginal lunules ; dentations narrowly fringed with white. 



Under surface. Primaries uniform dark chestnut-brown, with 

 the yellow central spot of upper side repeated. 



Secondaries same brown as primaries, with the same small 

 white submarginal lunules of upper surface ; above each of these 

 latter is a crimson more or less lunate spot, the one near the anal 

 angle very much larger than the others ; at the base of wing three 

 crimson spots placed one at shoulder, one within base of discoidal 

 cell, and one between the median vein and inner margin ; this 

 latter is the largest, and is sagittate in shape. 



From the condition of the abdomen I am unable to decide as 

 to the sex of the single example on which the above description 

 was based. 



Hab. — Amaz. Sup. 



This insect is closely allied to Pausanias Hew., but differs 

 decidedly from it in the following particulars : In the entire 

 absence of the large pale semitransparent apical patch, and in 

 the fringe of inner half of outer margin being white and black
