Both are Mesograptae , each represented by a single specimen in the Brit. Jlus. 

 I find in my notes that both produced on me the impression of M. Boscii, although 

 the description of S. coalescing reads more like that of M. jilaniventris Loew; tuo 

 female, described by Walker, is probably a ditt'ercnt species.
