State of Rio Grande do Norte. 
Natal. On the coast, in an arid, sandy and wind-swept district. 
Ceara-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 northwesterly direction. The surrounding country 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. 
Independencia. Dr. Heath and I spent a week at the little village 
of Itamatahy, near Independencia, 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 Ceard. 
Ceard. 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. 
Baturité Mountains. Mr. Williams, the Director of the railroad 
between Ceara and Inixadé 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. 
Maranguapé Mountains. Mr. 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 hillsides were 
taken several species not found elsewhere. 
State of Para. 
Paré. Nearly all of the material labeled Paré 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.
