A. Neuroptera. 



The tbree following families are closely allied and form 

 together with the Osmylidae (not present in this collection 

 and therefore not mentioned here) a rather independent group 

 within the Neuroptera. If we deal especiallj^ with the ner- 

 vature of the wings, we find that the Nymphidae may be 

 looked upon as the most primitive or the eldest family. Tn 

 this family we have no coalescence of the main-nervures. 

 In the subcostal area numerous cross weins are present. Bs

arises close to the base of the wing, and it emits numerous 

 branches. M is forked at some distance from the base of 

 the forewing, but at the base in the hindwing. In the hind- 

 wing ilf 2 gives off from its apical part a long series of branches 

 to the hind margin. Cu forks close to the base in both pairs 

 of wings. In the forewing Cu^ (and sometimes also C-w,) is 

 branched in the same peculiar manner as ilf 2 in the hindwing. 

 1 A, 2 A and 3 A present, at least in the forewing. In the 

 Ascalaphidae and the Myrrneleonidae the crossweins in the 

 subcostal area are lacking. Rs arises further out in the 

 forewing. M is apparently unforked in the forewing; but 

 as stated concerning the Myrrneleonidae it is due to the fact 

 that M2 in its free basal part only has the appearance of a
