Nesoleon pallens Klug. 



Is as I have identified it ; the abdomen has a narrow dark median 

 stripe, as in figure. 



Nesoleon lepidus Klug. 



Is very similar to N. pallens, but the abdominal marks are differ- 

 ent ; the segments having a mark extending along the posterior sides^ 

 as in figure. 



Nesoleon erythrseus Navas. 



=: A^. pallens. 



Nesoleon interruptus Navas and N. divisus Navas are both 



A^. varie gains (Brit. Mus.). 



Nesoleon rimatus Navas (Paris Mus.). 



= .V. variegatus. 



Nesoleon cognatus Navas. 



= N. pallens. 



Nesoleon scalaris Navas. 



= A'', lepidus. 



Myrmeleon punctulatus Oliv. 



Is a Nesoleon, and agrees with N. pallens. 



Myrmeleon abyssinicus Klap. 



^= Nesoleon pallens. 



M3n:meleon pertennis Klap. 



Agrees with Nesoleon variegatus. 



I have still another species of this genus which I have not seen in 

 any of the European collections. 



Nesoleon tumidus new species. 



In general marked like N. mysteriosus Gerst. but hardly as heavily, and 

 the pale area in apex of wings is therefore not as prominent. The wings are 

 as broad as in that species, and the outer margin more rounded ; there is no 

 mark up from end of anal vein ; the pronotum not as slender as in A'', mysteri- 

 osus, but with the three stripes complete ; the vertex has a black cross, the 

 front with a large black spot extending much below the antennae and covering 

 the front of the vertex ; the thoracic marks as in A'^. mysteriosus but broader ; 

 abdomen lined on base, beyond dark ; legs more heavily marked than in A''.
