The Butterflies of Chile. 291 



46. Co lias leshia. 



Papilio leshia, Fabricius, t. c., p. 477. 



This was abundant and very variable at Buenos Ayres, 

 and was found as high as 9000 feet near Puente del Inca. 

 I also took a single albino female on the Chilean side of 

 the pass at about 9000 feet on December 18th. I cannot 

 find that the species has been recorded previously west of 

 the Andes, and I did not find it anywhere in Argentina 

 along the frontier. 



47. Colias vauthieri.

 C. cunninghami, id., i.e., p. 471. 



Very abundant everywhere in Chile and in Argentina 

 along the frontier from sea-level up to 8000 feet and 

 probably higher. Extremely variable in size and in the 

 colour and markings of the female ; of which, however, 

 I have never seen an orange form. I could not see that 

 climate had any influence on the species, those from the 

 cold and windy plains about Lake Nahuelhuapi being 

 as large and bright as those from the damp warm forest 

 near Temuco. 



The spring brood, however (oninusctda, Butl.), which I 

 did not find, is small, and has a narrower black border on 

 both wings, and Cunninghami, But!., is a narrow-winged 

 southern form from Sandy Point. 



48. ? Colias euxanthe. 



Colias euxanthe, Feld., Reise Nov. Lep., ii, p. 196 

 (186.5). 



I took what I believe to be this species in the Horcones 

 Valley near Puente del Inca at about 10,000 feet on 

 December 12th, but the specimens were unfortunately lost 

 on the road when starting for Chile, and I have never 

 been able to recover the bag which contained them. As 

 it is a native of the mountains of Bolivia and Peru, there is 

 nothing improbable in its extending southwards.
