1890.] LEPTDOPTERA FROM BRAZIL. 553 



penetrated so far up the Araguaya River as Mr. Reynolds, the list 

 may be useful as showing the distribution of Amazonian Butterflies, 



I have to return my grateful thanks to Mr. F. D. Godman and 

 Mr. Osbert Salvin for help in determining many difficult species. 

 My ]>rincipal work on the collection has been done at the Natural 

 History Museum ; and I cannot sufficiently thank Mr, A. G.Butler 

 for his kindness in helping me with my determinations, which, with 

 the imprimatur of three such experienced Lepidopterists, will, I 

 trust, be found to be in the main correct. 



Mr. C. O. Waterhouse has also assisted me greatly with his advice 

 in my descriptions of the new species. 



Mr. Reynolds has sent me the following account of his journey : — 



"The Butterflies in question form part of a small collection 

 made by me while in the interior of Brazil ; and as I was not on a 

 Natural History expedition, but on one that had for its object the 

 exploration of the Araguaya and other rivers, I had to do my 

 collecting under considerable difficulty. 



" When barely 300 miles from Para our steam-launch was wrecked 

 in the first rapid on the Lower Tocantins, and although after great 

 delay and trouble we succeeded in getting her off the rocks and 

 patched her up, we found it i npossible, in the low state of the river, 

 to make our expedition in her; so my companion (Mr. Middleton) 

 and I decided to continue our journey in a canoe. We therefore 

 sent back the launch with all hands, instructing the engineer to stop 

 at the first settlement to buy a boat and hire a black crew, and send 

 them up to where we were encamped above the rapids. I may 

 mention here that after the wreck of the launch we got ashore on a 

 small rocky island in the middle of the rapids, and as we could not 

 get off for several days I had time to collect what little there was to 

 catch in the way of Butterflies, among them being specimens of 

 Mylothris iphigenia and Heliconius antiochus. 



" There was little room in our boat for more than a few neces- 

 saries ; but I managed to stow away a net, some camphor, and a 

 book of paper for wrapping up the Butterflies, and also a couple of 

 old biscuit-tins for storing them in. We expected to reach a settle- 

 ment on the Araguaya called Leopoldina in about three and a half 

 months, intending from there to go overland to the city of Goyaz, 

 then to return by the River Vermelho, and cross the country 

 between the Araguaya and Upper Tocantins Rivers, and on reach- 

 ing the latter to return by it to Para, We had therefore a very 

 long journey before us ; so, to avoid delaying the canoe, I used to 

 take the opportunity of our getting into the rapids or a very strong 

 current to land and go into the forests, making my way through 

 them as the boat was working up the stream, and in this way my 

 principal collecting was done. Any one who has been in a tropical 

 Brazilian forest will understand the difficulties I had to contend 

 with. Occasionally I would come across a bit of comparatively 

 clear ground where I could collect ; but generally my way lay 

 through the densest of vegetation, and it took me all my time with 

 my cutlass to make any progress at all. If I thought that the
