SUDILA FUSCIPENNIS, Sp. nov. 



Long. 10 mm. $ . 



Hab. Ceylon {Rot/mey). 



This species differs markedly from the preceding 

 in the form of the head; it is not so shining; the apex of 

 the clypeus, instead of ending in the middle in two sharp 

 teeth, has only a semicircular incision, the edges of which 

 do not project; the lower part of the head at the sides has 

 the projecting part not quite so lengthened, and is sharper 

 pointed at the apex ; the apex of the mandible is rounded 

 in ^. bidentata, here it is distinctly transverse and not so 

 much narrowed; another marked distinction is found in 

 the median segment; here its sides are bordered by a 

 furrow, which is hardly visible in the other; the legs are 

 distinctly fuscous, or rather piceous; the wings are dis- 

 tinctly smoky, being much darker coloured than in 5. 

 bidentata; the second cubital cellule is perceptibly shorter 

 above and beneath than the third; the two being conse- 

 quently together shorter than the first ; the second trans- 

 verse cubital nervure is straight, more oblique and more 

 narrowed towards the first at the top. 



If I had only S. bidentata to deal with, I should have 

 inferred that the female described below was its female ; 

 but having two undoubted males of distinct species, I am 

 unable to say to which of them it belongs, if indeed it 

 may not pertain to a third unknown male. I therefore 

 am compelled to treat it as a separate species.
