Sogra mordax Navas. 



S. iraciinda Navas does not differ, except in marks that are 

 variable. 



Acanthaclisis longicornis Rbr. 



The type has two series of costals except on the basal sixth of 

 wing; ten cross-veins before radial sector in fore wing, eleven branches 

 to radial sector, numerous marks between the radius and subcosta. 



Phanoclisis new genus, 



Pronotum slender ; costals crossed on base, not beyond, otherwise 

 like Acanthaclisis. 



Type, Acanthaclisis longicollis Rbr. 



Navas has given the name Nora for this species, but that name is 

 long since preoccupied. 



The type has about eight cross-veins before the radial sector in 

 each wing, ten branches to radial sector. 



Myrmelodes medius Navas. 



This is Mynnelcon doralice Bks. In my description I mentioned 

 the appearance of two radial sectors upon which character Navas has 

 made his new genus. But there is really but one radial sector (as in 

 all Myrmeleonidse) ; the fork of the radial sector has the cross-veins 

 so as to give it the appearance of a branch from the radius instead of 

 a branch of the radial sector. There are no more longitudinal veins 

 than usual in the family. The same structure appears in one species 

 of Palpares. 



Myrmeleon stigmalis Navas. 



This is the widespread M. obscurus Rbr. 



Myrmeleon buyssoni van der Weele. 



This is a true Myrmeleon, and in my table of African species runs 

 to 5, but the pronotum is yellowish, with two dark, submedian stripes. 



Myrmeleon hyalinus Oliv. 



Is a true Myrmeleon. The head is gone ; the pronotum in poor 

 condition ; the metanotum has three pale spots ; abdomen black, the 

 segments faintly margined behind with yellowish ; hind femora 

 brownish, hind tibiae dark at tip, spurs scarcely as long as first tarsal
