Genus Papilio 
daries, and the narrow bands of yellow spots on the wings 
closely resembling those found in the same location on the wings 
of P. asterias, $. Expanse, 2.50-2.75 inches. 
Early Stages. —These still await description. 
Indra occurs on the mountains of Colorado, Nevada, and 
California. 
(13) Papilio brevicauda, Saunders, Plate XL, Fig. 5, $ (The 
Newfoundland Swallowtail). 
Butterfly. —There are two varieties of this species—one with 
bright-yellow spots, one with the spots more or less deeply 
marked with orange-yellow on the upper sides of the wing. 
The latter variety is represented in the plate. The form with the 
yellow spots is common on the island of Anticosti; the other 
occurs quite abundantly in Newfoundland. Expanse, 2.75-3.00 
inches. 
Early Stages. —Both the caterpillar and the chrysalis show a 
very strong likeness to those of P. asterias. The larva feeds on 
umbelliferous plants. 
The range of the species is confined to the extreme northeast¬ 
ern part of our faunal territory. 
(14) Papilio bairdi, Edwards, Plate XL, Fig. 2, $ (Baird’s 
Butterfly). 
Butterfly. —This form, the male of which is represented in the 
plate, is the Western representative of P. asterias, and is charac¬ 
terized in general by the fact that the size is larger than that of 
asterias , and the postmedian band of yellow spots is broader. The 
female is generally darker and larger than that sex in asterias. 
Expanse, 3.25-3.50 inches. 
Early Stages. —Not unlike those of P. asterias. The cater¬ 
pillar feeds upon Umbelliferce. 
The seat of this species or form is Arizona, whence it ranges 
northward. 
(15) Papilio brucei, Edwards, Plate XL, Fig. 4, <3 (Bruce’s 
Butterfly). 
Butterfly. —This species, which is thought to be the result of 
a union between P. oregonia and P. bairdi, is found in Colorado. 
Oregonia is, unfortunately, not represented in our plates. It flies 
in Oregon and Washington, where P. bairdi is not found. In 
Colorado and adjacent regions meeting with the form bairdi , which 
ranges northward from Arizona, hybridization has occurred, and
