a short transverse streak placed on the inner series of gradate veinlets, and sundry 

 scattered dots at the base of the wing and on the dorsal margin ; veins and veinlets 

 whitish, with small and distinct black points, from each of which springs a blackish 

 hair ; most of the veinlets of the inner gradate series, some in the outer, and several 

 at the base of the costal area, black ; costal margin with pale ciliation, which 

 is very long near the base ; reticulation very open (transverse veinlets few) : 

 posterior wings with a black spot upon each side of the pterostigmatical region ; 

 neuration without black points ; some of the gradate veinlets in both series blackish. 



I have re-described this insect, partly because it was erroneously 

 placed by Mr. Walker in Ghrysopa, and also because I have before me 

 three fine examples taken by Capt. Lang at Masuri in June and July, 

 it having hitherto been unique. It is an anomalous Osmylus, and I am 

 not very clear as to the existence of ocelli, which I believe are present, 

 though certainly obscure. The species is best placed in this genus 

 provisionally.

In JHus. Brit. 



Lurid greyish-brown with yellow and blackish hairs intermingled. Antennae 

 yellow. Eyes grey. Prothorax stout, rather longer than broad. Legs pale yellow ; 

 anterior and intermediate tibiae with three black spots externally, of which one is 

 in the middle, one near the base, and one near the apex. 



Wings rather long, the apex acute, the apical margin straight ; greyish- 

 hyaline; pterostigmatical region with a blackish spot on each side, a smaller 

 blackish spot placed across two of the nervules of the outer gradate series, and 

 two or three more in the disc on the cubital region ; on the inner margin of the 

 anterior wings at about one-third of its length from the base, is a rounded raised 

 (convex) fuscous spot with black veins : neuration for the most part black, but 

 white here and there : sub-costa and radius in the anterior wings whitish, with six 

 pairs of long black spaces, and with black lines in the membrane in the sub-costal 

 area, one line being placed between each pair on the veins ; in the posterior wings 

 there are five pairs of black spaces on these veins, and no lines in the sub-costal 

 area : the net-work of the basal portion of the wings is moderately dense ; the 

 gradate series not parallel but converging on the inner margin. 



There is one example (not in good condition) in the British 

 Museum, indicated as from Port Natal ; but, without being able to affirm
