became abundant everywhere, and was generally dis- 

 tributed at elevations of 3000 to 5000 feet in all suitable 

 situations. I have figured three specimens to show the 

 great variation which exists in the species. The type of 

 lej)toneuroidcs is a very large male, and agrees well with 

 my largest. Though at first I thought that the androconia 

 on the male fore- wing of some specimens would distinguish 

 them, yet on careful comparison of my very large series I 

 am unable to separate what Butler calls jplumheola, which 

 he thinks the mountain form of leptmuuroides. This, 

 which is often smaller, was found by Edmonds at 6000 feet 

 in January, but was not out when I left Chilian at the end 

 of December. The species does not seem to occur in the 

 low country or on the coast of Chile, as Reed says he has 

 never seen it. It is probable that what he figures as 

 S. antcirdica is the same as j)/76»i&eo/a Butler, described 

 from the Straits of Magellan, which however he does not 

 allude to in his paper on Edmonds' collection. This is also 

 found at Port Famine, and was placed with ■pluitibcola in 

 the British Museum by Butler. Staudinger also figures as 

 Erchia ijlumhcola, var. Duscni, a variety of the same form 

 from the Rio Aysen in S. Chile, showing that the species 

 has a continuous distribution from about the latitude of 88° 

 to the far south of Chile. From the figure of Duscni I 

 do not see much to distinguish it, and it is to be hoped 

 that the practice of giving varietal names to specimens of 

 whose distribution and variation so little is known will not 

 be adopted as largely by authors as it has been in the 

 Holarctic Butterfly Fauna.

This is one of the common species of Chile which I 

 first took in the Chilian V-alley at about 3000 feet in 

 December, when it was just coming out. Afterwards I 

 found it on the coast near Coronel rather worn, and later 

 it was common in the Renaico Valley at 2000 feet, and 

 was found almost everywhere up to about 3000 to 4000 feet 

 and as far south as Nahuelhuapi, where, however, the 

 specimens show differences which might enable those 

 from Argentina to be separated from those taken in 

 Chile. In order to show these differences clearly, and
