12 Mr. H. J. Elwes' additiunal notes 



one female from Concepcion, in North Chili, is as small 

 and pale as the female type of minuscula. It then struck 

 me ih^iflaveola, Blanch., was probably the same insect, 

 so I wrote to Prof. Blanchard to know if the type still 

 existed. He replied that it is at Paris, and that he now 

 considers it simply a small variety of C. Vautieri, of 

 which the male was called C. ndilans by Boisduval. 

 The distribution of the species will then very nearly 

 coincide with the geographical limits of Chili.

C. Dinora, Kirby, Trans. Ent. Soc. Lond., 1881, p. 358, 

 described from a single female from Chimborazo which I 

 have seen in Mr. H. Grose Smith's collection, is probably 

 a form of dimera or Euxanthe. 



As I am unable to say with certainty what C. Euxanthe 

 really is, I can only apply the name provisionally to the 

 species now in question, which is a very puzzling one. 



Mr. Whymper in his Andean journey took several 

 specimens of both sexes of a small pale narrow-winged 

 Colias at great elevations in the Andes of Ecuador, 

 namely, Pichincha, 11,0000—12,500 ft.; Cayembe, 13,000 

 ft. ; Antisana, 16,000 ft. As far as I can judge from a 

 hasty examination, it belongs to the same section as 

 Vautieri, but differs markedly from that species, as well 

 as from Leshia and dimera, in their typical examples. 

 There exist, however, several specimens in Mr. Godman's 

 collection which seem intermediate between ? Euxantke 

 and others, namely, two from Poziuzu, on the Ucayalz 

 Eiver, collected by Whiteley ; two from Chili, which con- 

 nect it with Vautieri ; one from Bolivia (Buckley) ; and 

 one or two from the Sierra de Totoral, which are 

 probably a form of Leshia, though more like Euxanthe in 

 general appearance. The material is certainly insufficient 

 to decide anything, and I must therefore leave it a species 

 d'uhia for the present, though I have little doubt that 

 Whymper's specimens at any rate belong to a distinct 

 alpine species. He found them in company with dimera 

 at the upper limit of its vertical range, but going to a 

 much higher elevation, and not nearly so abundant as 

 that species. It resembles Scalidoneura Hermina, Butl., 

 very closely in general appearance ; but the venation of 

 the single type- specimen of that species is certainly dis-
