tips, the hind pair almost subfalcate at tig; about eleven crossveins 

 before the radial sector in forewings, six in 'hind wings ; about twelve 

 branches to radial sector in each wing. 

 Expanse 73 to 90 mm. 



From Erythrasa (Kristensen coll.). Types in collections 

 of Banks and Petersen. 

 Myrmeleon lynceus Fabr. 



From Victoria, Kamerun, and a smaller specimen from Togo. 

 The M. leucostigmatus Weele, from Kamerun, is a synonym. 



Myrmeleon formicaroides Weele. 



One specimen from Misahohe, Togo. 

 Myrmeleon quinquemaculatus Hagen. 



A common African species, specimens from Ginda (Petersen 

 coll.), Kilimandjaro (Banks coll.) and various places in Togo 

 and D. O. Afrika. M. polyzones Gerst. and M. rapax Kolbe 

 are synonyms as already stated by Van der Weele. 



Myrmeleon validus McLachlan. 



From Tamatave, Madagascar (Banks coll.). 



Myrmeleon atlas n. sp. 



Similar to M. 5-maculatus, but much larger. Face yellow, with a 

 median black spot below, the interantennal mark is not complete below, 

 but indented with the pale reaching up between antennae, and the mark 

 is not continued all around the lower edge of the antennal socket: 

 marks of vertex similar to those of M. 5-maculatus; the pronotum 

 shows a large pale median spot in front, and at each upper corner, with 

 a narrow extension backward; the abdominal segments are pale only 

 near middle (not to base as in 5-maculatus); the legs yellowish brown, 

 not plainly marked. Wings much more slender than in M. 5-maculatus, 

 especially the hind pair, and more falcate at tip; venation mostly dark, 

 subcosta and radius plainly interrupted with pale; stigma not very 

 distinct; there is a longer series of crossed veinlets before the radial 

 sector in forewings than in M. 5-maculatus. 



Expanse ll'li mm. 



From Kwidjwi, Ost Afrika. 



Gymnoleon new genus. 



But one crossvein before radial sector in the hindwings,. 

 several in forewings; costal series simple, cubital forks not very 

 much divergent; antennae rather close together at base; pro- 

 notum slender; no spurs; legs of moderate length, the last joint 

 of tarsus as long as the basal joint. 



Type — G. exilis n. sp. 



By absence of spurs it is related to the genus Cymnocnemia, 

 but differs at once in the very much shorter and stouter legs.
