this narrow- winged African form under the names bequaerti (Revue 

 Zoologique Africaine, p. 409, 1912) from Belgian Congo, and pudica 

 (Ann. Soc. scient. Brux., p. 82, 1914) from Transvaal. In my collec- 

 tion are twenty-four specimens ( <$ ) of the narrow-winged form from 

 Abyssinia and one <$ from Madagascar, and amongst the materials 

 here dealt with several specimens ( $ ) are also present. At present 

 I am not able to arrive at any definite conclusion, whether we have 

 to do with a distinct species or only a geographical form. 



I have prepared for the microscope preparations of the appendages 

 of the male of both forms, but it seems to me that the differences, 

 if any, are very small. Probably a close examination of the female 

 (which is not present amongst the narrow-winged specimens before me) 

 may decide the question. 



There is another African species, Chrysopa congrua, Walker (Cat. 

 Neur. Ins. Brit. Mus.,p. 238, 1853 West Africa, Congo, Central Sahara) , 

 belonging to the group in which the first cross-vein from Its in the 

 forewing joins M outside the basal median cell ; but this species is 

 easily distinguished by its dark brown antennae.

Two specimens, Cape Town (L. Pc'ringuey leg.) ; one specimen, Smith- 

 field, Orange Free State (Kannemeyer leg.) ; one specimen, Klerksdorp, 

 Transvaal (E. Gr. Alston leg.). 



The four specimens differ iu some degree, but it is easy to see that 

 they all belong to the same species. Face more or less suffused with 

 reddish or pale reddish brown. A black spot on each gena. Palpi 

 dark brown to blackish. No spot between the antennae. Vertex raised, 

 reddish brown ; along the front border of the elevation a blackish 

 A- formed streak in the two specimens. Antennae pale brown and 

 dark banded; second joint almost totally black. Prothorax reddish 

 brown (with irregular blackish markings) , broader than long, and with 

 truncate front angles. Meso- and metathorax with broad pale greyish 

 longitudinal median band and a broad blackish lateral streak. 

 Abdomen reddish brown with pale pleurae. The body dark brown 

 haired. Legs greyish yellow ; intermediate and hind femora with a 

 broad brown band before the apex ; tip of tibiae brown. Longitudinal 

 veins mostly pale in the basal half part of the wings ; but the basal
