12. Two series of costal cells for most of distance in fore-wing ; in hind- 



wing but one series Leiiiolemns. 



Three series of cells in fore-wing for part way, and two in hind- 

 wings Caliiieimirus. 



13. In hind-wings anal runs parallel to the cubital fork for a long dis- 



tance ; a line in apical part of both wings, and between the 

 cubitus and the hind margin ; antennae more than their 



diameter apart Ameroiiiyia. 



In hind-wings the anal does not run parallel to cubital fork for any 

 considerable distance, often not more than one or two cross- 

 veins between them 14. 



14. Antennae more than their diameter apart at base ; usually four 



cross-veins before radial sector in hind-wings 15. 



Antennae not diameter apart at base ; first branch of radial sector 

 at or before the end of anal vein in fore-wings 16. 



15. No line in apical part of the wings, but one between the cubitus 



and margin in fore-wings ; first branch of radial sector arises 

 much beyond the end of the anal vein ; spurs not much 



longer than first tarsal joint Myrnieleon. 



A line in apex of both pairs of wings ; spurs as long as two tarsal 

 joints ; first branch of the radial sector arises opposite the 

 cubital fork Amazoleoii. 



16. A comb of long bristles on the outer posterior edge of coxa I. 



Aiistroleoii. 

 No such comb of bristles Clatlironeuria. 



P^iren Navas. — This includes Mynneleoti modestus Blanch, 

 which agrees closely with P. bellator Navas and probably is 

 the same species ; there are three cross-veins before radial 

 sector in the fore-wing. 



Calineniurus Bks. — Elicura Navas agrees with this genus. 



Lincoya Navas. — This generic name has long been pre- 

 occupied in Zoology ; but the genus is perhaps the same as 

 Austroleon. 



Lemolemus Navas. — It is possible that this is the same as 

 the North American Brachynemuriis, at least I do not know 

 at present how to separate them. 



AMEROMYIA n. gen. 



Differs from Myr^necaehirus in that in both wings the anal 

 runs parallel to the cubital fork for a considerable distance ; 

 first branch of radial sector arises a long distance before end 

 of anal vein, two or three cross-veins before radial sector in 

 hind-wings, three or four in front-wings ; costal series simple ;
