A 9 specimen contained in the collection does not altogether agree 

 with Miss Ricardo's description in that the eyen are thinly pubescent. The 

 abdomen has median white triangular spots on segments one to four 

 inclusive with faint grey tomeutose banding on segments three and four 

 and broad apical lateral spots on segments two to four. The sub-callus 

 also bears a deep median longitudinal groove. The wings are uniformly 

 blackish-brown ; a small appendix present. Length, 14 mm. 



O^.s-. — It is considered inadvisible to more than make the above note 

 until the specimen has been comparetl with an authevitic specimen of N. 

 feDjHSOiii, Ricardo.

 no appendix present. 



(fbft. — 'I'he thorax of the two specimens before me is more or less 

 abraded but sufficient t hoi'acic clothing i-emains in the type to show its 

 nature. It is a very distinct species and may be separated from S. duddt, 

 Ricardo, ami S. IniiidntKs, Rigot, by its thoi'ax, alxlomen, legs, wings; the 

 ])alpi are also distinctive.
