GENUS 18. TYPE 



This genus has given infinite trouble in the past as regards 

 the identity of the species. The genitalia now offer a 

 certain amount of security; at the same time, it is important 

 to note that the species run exceedingly close to each other. 

 We give the full synonymy as a help. 



Valva long, delicate; costa and sacculus very weak; 

 transtilla a central arm curved, indent; saccus practically 

 divided. Uncus absent; socii well developed and firm, the 

 chief specific character. ^Edoeagus cardinate, sigmoid, 

 pointed. Cornutus a single spine. 



Ovipositor rather narrow. Ostium wide; bursa spined, 

 with circular spined star
