roundly curved downwards, its apex broadly and roundly curved 

 upwards. 



Length 15-20 millim.

Type in the British Museum. 



The examples that I have seen exactly agree with Cameron's 

 description in every way, excepting in having the labrum no 

 longer than half the clypeus and the nervellus intercepted at its 

 centre.* 



No doubt can remain that this species is congeneric with 

 S. bombycivorus, Grav., from which it differs in its basallv infurnate 

 radial and subapically infumate first cubital cells, in the basally 

 much more strongly inflexed internal cubital nervure, in having 

 the nervellus more strongly postfurcal and intercepted a little 

 lower, the radial nervure of the hind wing much more strongly 

 sinuate basally, with its recurrent nervure appreciably nearer the 

 apex of the wing ; the scutellum and rnetanotum are less rugulose, 

 and the former laterally carinate nearly to its apex ; the eyes are 

 equally euiarginate, and the ocelli large, in both species.

 all the specimens (including the type) that I have examined.
