 Taken near Puente del Inca in the Horcones Valley 

 at 10,000 feet on December 11th, and on the pass in 

 February at 11,000 feet. Chilean specimens are some- 

 what larger than those in the British Museum taken in 

 Bolivia by Sir M. Conway, and what Staudinger describes 

 as mjmfphza seems inseparable.

 I have had great difficulty in naming the Tatochilas I 

 found in Chile on account of their variation, and because 

 Blanchard has described three forms without figures which 

 I cannot identify certainly. 



The first is a well-known species which occurs all over 

 Argentina and Chile, and is known as autodice, Hltbu. 

 This I took near Buenos Ayres, When I crossed the pass 

 into Chile, I saw flying on the head of the valley at about 

 9000 feet a small silvery form, of which I have figured a 

 $ on Plate • XII, fig. 5. This had a rapid flight and 

 appears to be distinct, and to be what Blanchard called 

 microdice. I could not find the female here, but two 

 months later found what I think is the same species fairly 

 common at 4000 feet and upwards on the Argentine 

 frontier near Lake Alumine, and as far south as Lake 

 Nahuelhuapi. Of these I have figured a female from 

 Lake Quilleu, fig. 2, one from Nahuelhuapi, fig. 6, and 

 one from the Sierra de Pemehue, in Chile, fig. 1. A male 

 from Pulmari is like the figure which Mabille calls thcodice 

 in Miss. Cap. Horn Lep., xi, fig, 2.
