Thy maris fasciatus, n. s. 



Thymaris is one of Foerster's subgenera of Campo- 

 plegoidcs ; it is a subdivision of Cymodusa : wings without 

 an areolet, and post-petiole with a transverse depression. 

 Foerster has described no species of the genus, and the 

 only described species I know of is one by Brischke, 

 which has pale legs.
