State of Rio Grande do Norte. 



Natal. On the coast, in an arid, sandy and wind-swept district. 



Ceard-Mirim. North of Natal. The immediate vicinity of the 

 town is well cultivated, with fields of cane and cotton, and considerable 

 woody land and abundant water. 



Baixa Verde. The terminus of a little railroad running out of 

 Natal in a northwesterlv direction. The surrounding countrv is 

 hilly and very arid, with much scrub and cacti. At the time we col- 

 lected here everything was dry and collecting was to be had only 

 beneath stones, with which the ground was strewn. 



State of Parahyba. 



Indepcndencia. Dr. Heath and I spent a week at the little village 

 of Itamatahy, near Indepcndencia, as guests of Messrs. Nye and 

 Tessire, engineers on the local railroad. The country is hilly, with 

 abundant vegetation and water. Bamboo breaks afforded interesting 

 collecting. 



State of Gear a. 



Geard. On the coast in extremely arid surroundings. There is a 

 good stream near the city, along which was a fairly abundant fauna. 

 This and the following are type localities of many of the ants described 

 by Mayr and Forel. 



Baturite Mountains. Mr. Williams, the Director of the railroad 

 between Ceara and Inixada gave the members of the Expedition an 

 excursion to the latter village. En route it was possible to collect at 

 several points in the mountains. 



Maranguape Mountains. INIr. Lieb, Assistant Geologist of the 

 Expedition, and the writer made a side trip into these mountains and 

 collected for a day. In the humid canyons and on the hi^sides were 

 taken several species not found elsewhere. 



State of Pard. 



Para. Nearly all of the material labeled Para was taken in the 

 forest on the outskirts of the suburb Souza. 



Santarem. Visited on our return trip down the river. We were 

 able to spend only a few hours here, chiefly among the scrub in the 

 sandy region back of the town.
