whitish; crossveins in the gradate series and part of the adjoining longitudinal

In » Notes from Leyden Museum», XXXVI, 267, fig. 3, 1914, I have 

 mentioned a specimen (deposited in Leyden Museum) from Agualani, Casa- 

 baya, S. E. Peru, as belonging to Gayomyia falcata. At that time I did not 

 possess the work of Blanchard, and I had only at hand a copy of the de- 

 scription. I am now convinced in regarding that specimen as belonging to a 

 new and undescribed species, closely aUied to Blanchard's species. 



Hemerobius Skottsbergi Navas, The Natural History of Juan Fernandez 

 and Easter Island, Vol. Ill, 125. 



One male and one female were present from Masafuera, and one male 



from Masatierra, Juan Fernandez 

 (Backstrom leg.). 



I think the species is the same 

 as Hemerobius Bolivari Banks (Proc. 

 Ent. Soc. Wash., vol. XII, 159, 1910) 

 from Columbia and Peru. I possess 

 two female specimens of the last 

 named species from Peru, determined 

 by Banks himself, and they agree 

 exactly with those from Juan Fer- 

 nandez. I give here a drawing of 

 the anal appendages of the male 

 of Skottsbergi, and when a male 

 of Bolivari comes at hand, the question as to the synonymy can then be 

 settled.
