170 THE CANADIAN ENTOMOLOGIST. 



female have been described — an orange and an albino. Until the males 

 are obtained from the egg, or until some collector at the summit of the 

 Rockies, or some other range of mountains, takes the male and female /// 

 coitu, the male will remain a matter of doubt. 



My own humble opinion is this : If the female — albino variety — is 

 Elis, as described by Mr. Stecker, the chances are that there will be 

 lemon colored males as well as orange, and that these males were taken 

 by me in 1SS4. There are other species of Colias that have both lemon 

 colored and orange males — such as C. C/iristina — upon some of which 

 not a vestige of orange can be discovered. 



ON THE POSITION OF COLIAS HAGENII, Edw. 



BY W. H. EDWARDS, COALBURGH, WEST VIRGINIA. 



In Papiho, 3, 159, 1883, I described Colias Hagenii as a new 

 species. I related that Mr. T. L. Mead had brought this butterfly from 

 Colorado, in 1871, and that we both were then satisfied that it was not 

 Philodice; that in the summer of 1883, Mr. H. W. Nash, at Pueblo, 

 Col, had sent me some chrysalids of this form, and I noticed that the 

 dorsum was marked by two longitudinal lines, which seemed to indicate 

 sub-dorsal lines in the larva, and which are not present in the larva of 

 Philodice ; that I wrote Mr. Nash to observe as to that, and he soon 

 replied that the larvae he then had on hand did show sub-dorsal lines 

 such as are characteristic of many larvae of Eurytheme ; that I had been 

 unable to get live eggs from Pueblo subsequently that year, owing to the 

 heat which destroyed them en-route, but that Mr. Nash had made obser- 

 vations on the ground, and sent on larvae in alcohol which showed broad 

 sub-dorsal bands, that, he said, in life had had red running through them. 

 That other larvae showed white sub-dorsal lines only, and still others had 

 no trace of such bands or lines, any more than Philodice. All which was 

 like Eurytheme, except that in that species the red was not within the 

 band, but over it in broken bits ; and also under the bands in Eurytheme 

 were often black points. The larvae of Eurytheme in these varieties are 

 figured in But. N. A., vol. 2, plate 21. 



I did not at the time describe the species, but mentioned it as the form
