I possess a single specimen of each sex of this species, 

 ■which vary as above. Whether this represents sexual di- 

 morphism, as I am inclined to believe^ or simple variation^ 

 can only be decided when a series of specimens are available 

 for examination -

Fowler has included the S. paraUela,Vi'aW., as a synonym 

 of S. lineata, Walk. The two species are, however, quite 

 distinct by markings of tegmina and shape of face, and 

 Stal correctly pointed out the identity of the former species 

 with C. festa, Germ.
