LiBELLULIDj;. 



1. Palpopleura Portia, Drury. Occurs throughout 

 Tropical Africa, and varies much according to locality. 



2. Libelhda sp. ?. I sent this insect to M. de 



Selys-Longchamps, who says it is scarcely to be separated 

 from a common but undescribed Brazilian species, L. 

 hilineata, (Hagen, MS.) . I possess an example from 

 Zanzibar, taken by Dr. Kirk. 



Myrmeleonid^. 



1. Palpares latipennis, Ramb. And a larva probably 

 of this species. P. indemens, Walker, from Natal, and 

 P. cephalotes, Walk, (nee Klug), from Congo, are most 

 likely forms of the same species. 



2. Myrmeleon sp. ?.
