50 THE CANADIAN ENTOMOLOGIST. 



gynandromorphs, are by no means unknown." He mentions seventy- 

 one published eximples of such, of which eight belong to the Papilioninae : 

 ••' most of these show complete bilateral distinction, the wings of one side 

 being of one sex, of the other of the opposite sex. Dr. W. J. Holland 

 writes me that he has a P?pilio Polyxenes" (Mr. Scudder's name for 

 Asterias) "collected by Mr. Mead, in which the abdomen is female, 

 while the wings have the male colouring." The example I describe 

 above is, then, just the reverse of the one in Dr. Holland's collection, the 

 abdomen being male, the wings female. I hope to get this specimen, as 

 well as the albino male Colias, figured in my Volume HI. 



3. Papilio Bairdii. 



Mr. Bruce also sent me eggs of P. Bairdii, from West Colorado, in 

 189 r, obtained by cjntining the female over the food-plant ; and from 

 these I reared several larvae to pupa and imago. The butterflies in no 

 way differed from the typical forms. The larvae were distinctly different 

 from the Asterias larvae, which were feeding at the same time. I have 

 the set of drawings of them by Mrs. Peart, and shall certainly figure the 

 stages in Butt. N. A. 



4. New species, Papilio Hollandii. 



Mr. Bruce obtained in West Colorado three examples, male, of a 

 Papilio wholly unknown to me, and which lies between the sub-groups of 

 P. Zolicaon and Asterias. Like the species of the former sub-group, the 

 abdomen is yellow. In all the members of the other sub-group the 

 abdomen is black, with rows of yellow spots. The upper side of both 

 wings in these examples is not distinguishable from the male Bairdii, the 

 yellow bands and spots being of the same character, and the anal ocellus 

 has its sub-oval pupil connected by a black ligament with the marginal 

 stripe. On the under side the facies is quite different from Bairdii, by 

 reason of the marginal yellow spots being very large and confluent ; the 

 spots of the mesial band very large, fully as much so as on the upper 

 side. The abdomen is wholly yellow, except for a black dorsal stripe 

 and four fine lines beneath, two on either side the venter. 



It has been suggested that these might be hybrids between Zolicaon 

 and Bairdii. I know nothing of hybrid butterflies, and if there is
