tion were turned over to Dr. W. M. Mann, Assistant Curator in the 

 Division of Insects of the U. S. National Museum, and a man of wide 

 experience in tropical travel and collecting. Under his direction the 

 party will continue its work in Bolivia and Western Brazil, making 

 studies and collections in the valleys of the Rio Beni and some of its 

 tributaries, including the Rio Negro and Rio Ivon. The trip into Col- 

 ombia as originally planned, was modified, and the party will con- 

 tinue its work in Bolivia and Brazil until March or April. The botani- 

 cal work of the expedition is being continued by Dr. O. E. \Vhite, a 

 representative of the Brooklyn Botanical Gardens and Harvard Uni- 

 versity, assisted by Seiior Cardenas, a young Bolivian botanist of prom- 

 ise, who was taken on as a member of the party at the request of the 

 Bolivian Department of Agriculture. 



In spite of the change of plans for the Colombian part of the jour- 

 ney and the early termination of Dr. Rusby's active work in the field, 

 we feel confident that the results when ultimately gathered together 

 will prove the expedition to have been well worth while and to have 

 fully repaid expenditures made therefor. Before Dr. Rusby left the 

 party they had collected over 3000 plant numbers and to this many 

 more will be added. They have already shipped to this country many 

 boxes containing specimens of economic importance. Other depart- 

 ments of the work of the expedition have been equally successful. Dr. 

 Mann has collected over 100,000 insects, including 125 different 

 species of ants. The collection of fish is also important and growing 

 rapidly as they descend to the deeper and wider rivers.

COMPILED BY E. T. CRESSON, JR., AND J. A. G. REHN. 



Under the above head it is intended to note papers received at the 

 Academy of Natural Sciences, of Philadelphia, pertaining to the En- 

 tomology of the Americas (North and South), including Arachnida and 

 Myriopoda. Articles irrelevant to American entomology will not be noted; 

 but contributions to anatomy, physiology and embryology of insects, 

 however, whether relating to American or exotic species, will be recorded. 



The numbers in Heavy- Faced Type refer to the journals, as numbered 

 in the following list, in which the papers are published. 



All continued papers, with few exceptions, are recorded only at their 

 first installments. 



The records of papers containing new genera or species occurring north 

 of Mexico are grouped at the end of their respective Orders.
