In the table ia Trans. Ara..Ent. Soc. xxv. p. IU.5, this 

 runs out at 10, because the clypeus is yellow and there is no 

 supraclypeal mark excej-.t a minute scarcely visible dot. It 

 falls near to S. zona/is (Cresson), known only in the male, 

 but is too different to be its female.

In my table cited it runs to 6, birt falls out on account of 

 the peculiar face-markings. In Fowler's table (' Psyche,' 

 Sept. 1899) it runs to 8. cincta (Cress. )j but that has the 

 face all dark in the female.
