STUDIES IN AMERICAN TETTIGONIIDAE 

 (ORTHOPTERA)

BY JAMES A. G. REHN AND MORGAN HEBARD 



A REVISION OF THE SPECIES OF THE GENUS 

 ATLANTICUS (DECTICINAE) 



The acquisition of certain very peculiar types belonging to 

 this interesting genus, not referable to any of the generally 

 recognized forms, made necessary not only the examination of 

 all the material in our possession or in our charge, but also that 

 in the other more important American collections. As a result 

 we have been compelled to completely revise the classification of 

 the genus, to correct the assignment of certain of the older names 

 and to distinguish the more permanent from the many relatively 

 variable, and therefore taxonomically valueless, characters found 

 in the genus. Although the number of valid species in the genus 

 has been considerably increased, but two were previously un- 

 known, as a number of previously synonymized or incorrectly 

 assigned names represent well characterized species, which are 

 here correctly located.
