Of this handsome South African species, which was originally 

 described from Kaffraria, Cape Colony, the Museum as yet possesses

 the Transvaal, in 1895 (H. P. Thomasset).

PLATE IV., FIG. 31. 



Like the last, this species also belongs to South Africa, was 

 originally described from Kaffraria, Cape Colony, and is at present 

 represented in the Museum Collection by only two female specimens, 

 which however in this instance were taken at " Port Natal," in 

 1855 and 1857 (Oueinzius}. 



* Owing to the first posterior cell in the wings of this and the following species 

 (P. brunnipennis, Lw.) being open, the two species strictly belong to the genus 

 Diatomineura, Rond., and since the eyes are bare, to the subgenus Corizoneura, 

 Rond.
