PSYCHE. 



[May 1S95. 



but none above. The epigyniim consists of 

 a shallow cavitj divided behind by a septum 

 which is connected with the posterior ridge, 

 in front are two transverse lines and further 

 in front the usual anterior lobe, behind each 

 side appears an oblique convoluted body 

 beneath the surface, and a curved ridge. 



One .specimen of this fine species 

 from Punta Gorda, Florida ; collected 

 by Mrs. Annie T. Slossoii. 



COLIAS HECLA. 



Mr. Bean in an interesting paper in the 

 April Psyche on " A Comparison of Colias 

 hecla with Colias meadii and Colias elis " 

 seems to think I made a blunder in describ- 

 ing a pallid $ form of hecla. It appears 

 to me quite illogical for Mr. Bean to 

 theorize in regard to the lesser degree of 

 variation in hecla, and because the discovery 

 of a pallid female somewhat interferes with 

 these theories, to assume that the identifica- 

 tion of the pallid female is probably an 

 error. The specimen in question came 

 from Northern Greenland, is bright, beauti- 

 ful and faultlessly perfect, and there is not 



the slightest doubt as to what species it is. 

 Mr. Bean's paper is a very valuable one, but 

 in my opinion there is but one key to the 

 solution of all such problems in the Rhopa- 

 locera, and that is the study of many indi- 

 vidual specimens representing the entire 

 geographical distribution. If it were possible 

 to get many series of specimens of hecla, 

 elis, and meadii from the entire territory, 

 in a line, from the home of the Arctic high- 

 lander to New Mexico, we would be able 

 to solve the problem. I am inclined to 

 think that elis will be found to have a 

 greater range than is at present supposed. 

 To show my opinion of the effect of distribu- 

 tion, I think where a species covers consid- 

 erable territory that it would be quite possible 

 in many instances for one of experience in 

 such studies to tell almost exactly from 

 whence it came. By using measurements, 

 etc., I think it would not be difficult to 

 prove the Lapland hecla quite distinct from 

 the Greenland one, but get a series repre- 

 senting the intervening territory and your 

 new species will probably fall into the 

 second line. I should also state that Colias 

 nastes, which Mr. Bean thinks I mistook for 

 hecla, is not found in Greenland.
