Four New Species of South African Hemerobiidgs. 37 



long, sutures deep, interspaces slightly convex, the median, some- 

 what broad buff band is hardly visible past the middle, and the 

 lateral ones are sub-dorsal ; these bands are no longer distinct on 

 the metanotum ; the under side is concolorous, flavous like the legs, 

 which have the ultimate tarsal joints slightly infuscate ; wings 

 hyaline with a very distinct flavous tinge ; reticulation also flaves- 

 cent, especially the sub-costal and radial veins which are con- 

 spicuously yellow, very bristly, and reaches the pterostigma, which is 

 distinct ; the wings ara two and a half times as long as broad, not 

 acuminate, but not rounded either at apex, with the posterior margin 

 plainly sinuate at a short distance from the apex ; hind-wings very 

 long, very slender, nearly twice as long as the fore-wings, but 

 curving strongly downwards at about two-thirds of the length, 

 where each broadens, becomes plainly quadri-costate, and tapers 

 suddenly near the tip, the enlarged part is more bristly than the 

 anterior, and the constricted part is clothed with a long, black villo- 

 sity ; the whole wing with the exception of the constricted apical 

 part is flavescent. 



Length 15 mm. ; expansion of fore-wings 53 mm. ; length of hind- 

 wing from base to curve 41 mm. ; with the curve included 51 mm. 



This species cannot be mistaken for any other South African 

 one. It is probable that in the $ the fore-wings are a little more 

 acuminate.
