South African Neuroptera. 513 



broad, pale olivaceous grey, the anterior angles slightly reddish, and it 

 has two short black lines on each side. 



I suppose that gigantea is more closely allied to neurodesihun to the 

 two other species.

Of this species a somewhat large number was sent me. 



Seven specimens, Kimberley, Cape, 1912 (Bro. Power leg.) ; five

The South African specimens differ in some points from the European 

 ones. The reddish or brownish-red streak on each cheek and on each 

 side of the clypeus are often wanting, and when they are present they 

 are not so distinct. The veins and the body are not so closely haired. 

 The European specimens form a rather homogeneous unity, and they 

 vary only in a small degree. Some specimens are more or less reddish 

 suffused on the face, some others possess faintly brown lateral margins 

 on the prothorax, or possess a dark indication on the costal cross-veins 

 at their junction with Sc ; but in the African specimens we meet 

 with two rather different forms the usual broad-winged European 

 form with the rounded apex of the wings, and the narrow-winged 

 form with the rather acute tip of the wings and as a rule with more 

 lanceolate basal median cell in the forewiug. Navas has described
