As Entomologist to the Stanford Expedition, it was my privilege 
to spend the summer and fall of 1911 making collections in various 
parts of Brazil. Natal and Ceara on the East Coast were our head- 
quarters for the first three months, and from these stations side trips 
were made to nearby points. In the early part of July, when the 
other members of the party returned to the States, Dr. Fred Baker 
and I remained at Para, and subsequently went up the Amazon to 
Manaos. We hoped to be able to get into the region of the upper 
Rio Madeira. Our hopes were more than realized, for Mr. May, 
senior member of the firm, May, Jeckyll & Randolph, then engaged 
in constructing the Madeira-Mamoré Railroad, took an active interest 
in our work and provided us with transportation from Manaos to 
Porto Velho on the little steamer owned by the company, and with 
letters to several of the engineers and medical men. From the time 
of our arrival at Porto Velho till we left, we were shown the greatest 
hospitality by everyone in the foreign colony. Dr. James Laidlow 
and Messrs. Nixon and Troop cared for us in their homes at Porto 
Velho, while along the line of the railroad and in the construction 
camps everyone gave us all possible assistance. Some of the men, as 
Messrs. H. N. Burton and Fry, themselves interested in insects, 
collected during spare hours and generously turned over to us such 
specimens as we wanted. It is impossible adequately to express our 
appreciation of the kindness with which we were treated while on the 
Madeira-Mamoré, 
As a great deal of territory was covered, and several distinct faunal 
regions visited, it seems advisable to give a list of the localities in which 
collections were made. These are:
