ENTOMOLOGY 
MEDICAL AND ECONOMIC ENTOMOLOGY 
By J. BEQUAERT 
Tuer Arthropoda collected during the Harvard African Expedition are so nu- 
merous that it is impossible to even enumerate them all in this Report, since 
many of them are as yet unidentified. I have therefore limited my studies 
chiefly to groups that are of medical or economic significance, though I have 
included lists or brief accounts of some others that are of especial interest on 
account of their habits or distribution. 
To my own Report are appended a series of entomological contributions 
prepared by some of my colleagues, all of whom I wish to thank for their kind 
help. In some groups, I have also been greatly assisted with identifications 
by specialists. For such help I am indebted to Mr. Nathan Banks (in the 
Ricinulei), Dr. H. EK. Ewing (in the mites, sucking lice, biting lice and fleas), 
Prof. Alfred Emerson (in the termites), Mr. J. A. G. Rehn (in the Orthoptera), 
Mr. F. W. Edwards (in the mosquitoes and midges), Dr. J. Waterston (in the 
biting lice), and Dr. W. Horn (in the tiger-beetles). 
In addition to the contributions contained in the present Report, the fol- 
lowing papers dealing partly or wholly with insects obtained by the Harvard 
Expedition, have been published elsewhere.
