154 ENTOMOLOGICAL NEWS. [April, '13 



gan insect agree with those from Jamesburg, but those from 

 New Mexico, of which I have a very long series and which 

 are certainly comyntas, approach in the length of the hooklike 

 extremities of the clasps the Californian examples of amyntula 

 and also in the straight spike-like falces of the tegumen. We 

 thus have a somewhat similar evolution of the genitalia going 

 on with comyntas, as I have shown to be the case with amyn- 

 tula, both species being full of interest from this point of view. 



From the facts of their life-history and their distribution, as 

 also from the fact of their flying together in the Mount Shasta 

 district, together with the differences in the genitalia, I cannot 

 conclude otherwise than that the two species are distinct from 

 each other and that, as already stated, they are nearest to 

 coretas and not to argiades. Amyntula does not appear to 

 have extended its range far to the East and in this respect 

 differs from its more dominant ally, comyntas, which has 

 spread itself right across the American continent into Califor- 

 nia. Manitoba and the western side of Lake Superior appear 

 to be its eastern limit, at least I can trace no record further 

 east. The localities other than those already named are : 

 Stoney Mountain near Winnipeg (Wallis) ; High River, Al- 

 berta (Williams); Lake Kootenay, Sicamus, Penticton, Ash- 

 nota, B. C. (all Mrs. Nicholl) ; Vancouver (Day) ; Victoria, 

 B. C., California, widely distributed; Utah (common); Colo- 

 rado, Western Montana, Arizona, Nevada. 



It is not unlikely that some records may have escaped my 

 notice, but it will be seen that amyntula has a much more lim- 

 ited range than comyntas, especially so east to west. Three 

 local races of amyntula have been described, viz., monica from 

 Southern California, tijua Reakirt, and also herrii Grinnell. 

 Mr. Grinnell, with whom I have had the pleasure of a short 

 correspondence, is evidently a very keen observer, but I think 

 if he had had the advantage of having the type of amyntula 

 before him that he would not have described the form. My 

 friend, MT. Oberthiir, has kindly lent me his type of this spe- 

 cies and I have it now before me, so that I can compare it 

 accurately with the description of the variety. The differences
