Hob. North China (Shanghai). (Coll. R. Fortune, Esq.) 



This insect so closely resembles the male of S. emarginata, that, 

 with the exception of the pale margins of the segments of the 

 abdomen, there is scarcely another specific difference ; both have 

 the second submarginal cell narrow, which receives the first 

 recurrent nervure in the middle.
