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-Mamore 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-Mamore. 



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:
