A PRELIMINARY LIST OF THE ARTHROGASTRA OF NORTH 

 AMERICA (EXCLUDING MEXICO.) 



BY LUCIEN M. UNDERWOOD, PH. D., SYRACUSE, N. Y. 



The Arthrogastra of North America have scarcely been studied except 

 in two or three families, the principal part of the American literature 

 consisting of scattered notes and descriptions. Two or three more preten- 

 tious papers have been published by Wood, Putnam and Hagen. A 

 broad field for study is open for future investigators. In order to call 

 attention to the group and secure such co-operation of collectors as may 

 be possible, the following preliminary list of twenty genera and fifty-nine 

 species has been prepared. A few forms are added from Lower California 

 and Cuba which will probably be found within the limits of the Uilited States. 

 Additions and corrections to the list are solicited, as well as specimens 

 from all parts of the country, for which a suitable return will be made.
