SO I remained for only three days. The next stage of the journey 

 was on a river steamer travelhng to Obidos (Obydos, Bates). On 

 board the steamer I was able to collect nmnl^ers of insects around 

 the electric lights. The thick forest around Obidos is rich in game 

 and insects are plentiful. It is what might be called a "Natural- 

 ist's Paradise." Here the largest of its genus, a tree-top flyer, 

 Morpho hecuba, is found. To offset the pleasures of this paradise, 

 mosquitoes are extremely bad both day and night. I left Obidos, 

 travelling by night about 150 miles up the Trombetas River to a 

 village called Oximinia, a small place with about 600 people, situ- 

 ated on the edge of the forest. This place is very secluded and 

 rarely visited by naturalists. After ten days of good collecting I 

 returned to Obidos. From Obidos I continued my way up the 

 Amazon to Parintins and thence to the town of Itacoatiara (Ita- 

 coatiara or Serpa, Bates). I remained there for three weeks and 

 then pushed on to Manaos (Barra or Manaos, Bates), a beautiful 

 city situated on a hill. After collecting about the outskirts of this 

 city for a few days, I moved on to a place called Flores, about ten 

 miles out from Manaos on the electric line. Here I was successful in 

 making a large catch of insects, many being new to science. 



Teffe (Ega, Bates), about 300 miles up the SoHmoes River, an- 

 other of the main tributaries of the Amazon, was my next objective. 

 The settlement here seemed to be almost the same as when Bates 

 was here over sixty years ago, excepting the fine brick building 

 erected hj the Roman Catholics as a residence for their priests. 

 The most striking thing to me was the luxuriance of the vegetation 

 around Teffe Lake and the abundance of Micro-Lepidoptera and 

 Diptera. While at Teffe I managed to ward off a severe attack of 

 malaria which was threatening me. I stayed in this vicinity for 

 two months and then boarded the steamer ''Belem," travelling 

 further up the Solimoes to Iquitos, in the Peruvian Department of 

 Loreto. This trip required ten days. While on board the steamer 

 I was able to catch a number of insects attracted to the electric 

 lights at night. Landing at Iquitos, I found it to be a large, up-to- 

 date city, not very far behind our northern cities. The forest about 

 the place proved excellent for collecting. One day while walking 

 in the forest, I noticed a hole in the side of a bank, apparently the 

 entrance of some animal's burrow. By swishing my net about 

 the entrance, I caught four or five crane-flies and later on found 

 the same occurrence, the crane-flies representing one or two spe- 

 cies. At this place, crane-flies were noted in numbers swarming 

 in the sunlight. After two weeks' time, I caught a steam launch 

 that plies between this place and Yurimaguas on the Huallaga 

 River, a distance of some 550 to 600 miles. Here I lived with an 

 Indian family who were very hospitable. Looming up in the west 

 I could see the Andes Mountains. I procured a guide through my 

 Indian host and took a walk into the forest. The air here seemed 

 much fresher than that of the low-lying regions of the Amazonian 

 Basin. 1 lemained at Yurimaguas for about a month and then
