June, I9I3-] BaNKS : NOTES ON AFRICAN MyrMELEONID^. 151 



joint; wings acute, and almost falcate at tips; many cross-veins before 

 radial sector in each wing, nine or ten branches of the radial sector; 

 venation entirely pale. 



Myrmeleon cinereus Klug. 



This is a true Myrmeleon; the head has a dark interantennal mark, 

 a spot above it on middle of front, and three spots across vertex; 

 prono'tum as figured. 



Myrmeleon obscurus Rbr. 



Is a true Myrmeleon, as identified by Van der Weele ; it has seven 

 to eight cross-veins before the radial sector in fore wings, five cross- 

 veins in hind wings, eight branches of radial sector; subcosta, radius, 

 and cubitus strongly marked with dark. M. eapciisis Rbr. appears to 

 be the same species, but rather larger, the venation and markings are 

 the same. 



M. fictus Walk, is the same species; M. sccretiis Walk, is probably 

 the same, but the type is broken. 



Nesoleon fasciatus Navas. 



Is a true Myrmeleon and close to M. obscurus, perhaps the same. 



Myrmeleon ochroneurus Rbr. 



Is a true Myrmeleon. There is a large mark on front of the head 

 reaching below the antennae ; vertex and pronotum as figured ; thorax 

 with some submedian pale spots ; legs pale. Wings rather slender 

 and acute, subcosta and cubitus and its branches dotted or spotted 

 with dark, otherwise venation is pale; 14 cross-veins before radial 

 sector in the fore wings, 8 in the hind wings, 10 branches to radial 

 sector, a line through cubital area in both wings; in fore wings the 

 radial sector arises plainly beyond the end of anal vein. Related to 

 M. lethifer and M. medialis. 



Formicaleo madagascariensis Weele. 



Is a true Myrmeleon, related to 71/. furcatus. 



Hagenomyia luctuosa Navas. 



This is Myrmeleon lethifer Walk., the M. nigridorsis Kolbe. In 

 the Brit. Mus. Navas has identified an entirely different insect as M. 

 lethifer.
