140 ENTOMOLOGICAL NEWS [M^y, '20 



delay of thirteen days occurred at the Island of Santa Lucia, where interest- 

 ing and unexpected collecting was done. At Rio de Janeiro he was joined 

 by a volunteer assistant, Mr. R. Gordon Harris. 



After spending some time in Rio de Janeiro, a trip was made in company 

 with Brazil's foremost entomologist, Dr. Adolph Lutz, to the State of 

 Minas Geraes in the north, as far as to Pirapora, the head of navigation 

 on the Sao Francisco River; some days were spent at Lassance on the 

 Rio das Velhas as guests of the Institute Oswaldo Cruz. It was at this 

 place that Dr. Chagas first worked out the details of the transmission by 

 a Redwing bug {Conorhinus) of a trypanosome causing a ver^' serious 

 endemic disease of the region. Some days were also spent in the alpine 

 meadows at Diamantina, Brazil's highest city, and also as guests of the 

 State of Minas Geraes at the Capitol, Beldo Horizonte. 



Returning to Rio de Janeiro, the party proceeded to cross the States 

 of Sao Paulo and Matto Grosso by rail to Corumba on the Paraguay 

 River, and thence to Urucum. Interesting collecting was encountered 

 at various points along this trip, but especially at Urucum, 20 kilometers 

 from Corumba, on an isolated mountain range at an elevation of 2200 

 feet, at the upper limit of a tropical forest. Here, despite continuous 

 rainy weather, a very interesting and abundant fauna was encountered. 



From Corumba they proceeded by rail via Sao Paulo to Uruguayana on 

 the Uruguay River, at the Argentinean frontier, a distance of 2500 miles; 

 from there they were about to proceed, when last heard from, to the falls 

 of the Iguazu on the Alta Parana River. 



The plans of the party contemplate spending a brief while in Argentina, 

 at Buenos Aires, La Plata, Cordoba, Mendoza and possibly Tucuman, 

 a visit to Montevideo, and then to spend from six weeks to two months 

 in Chile, visiting several places, to as far south as Chiloe Island; thence 

 to Oruro, Cochabamba and La Paz in Bolivia, and to Lima in Peru. 



At Lima,. Dr. W. T. M. Forbes and Jesse Williamson will join the ex- 

 pedition, which will, if conditions prove favorable, cross the xAndes via 

 the central route and down the Pichis, Pachitea, Ucayalli and Maranon 

 Rivers to Iquitos; stopping at favorable points on the eastern side of the 

 Andes. The party will return to New York in September next. 



The Expedition is entrusted with the delivery of extensive collections 

 of North American insects and of vertebrates to four scientific institutions 

 in South America. While not neglecting general collecting. Dr. Bradley 

 is devoting especial attention to the collecting of Hymenoptera, especially 

 of the aculeates, and is endeavoring to obtain series of nests of \'espidae 

 with their inhabitants. Mr. Harris is doing general collecting of insects. 

 Dr. Forbes will devote his attention primarily to Lepidoptera, and relieve 

 the other members of the necessity of devoting attention to this time- 

 exacting group after he joins the Expedition. Mr. Williamson will collect 



Odonata.
