connected to the large black spot behind it. Seven cross-veins before 

 radial sector in hind wings; eight branches to radial sector in both 

 pairs; abdomen shorter than wings. 

 Expanse 40-45 mm. 



From Deutsch Sud. W. Afrika; Grootfontein, Okahandya, 

 and Gr. Namalaut. 



Nesoleon mysteriosus (Gerst.). 



From various places in D. O. Afrika (Berlin Museum); 

 and Mt. Algego, Uganda (Banks coll.) 



Nesoleon variegatus (Klug). 



From Harrar, Abyssinia (Petersen and Banks coll.) 



Nesoleon trivirgatus (Gerst.) 



From Grootfontein, D. S. W. Afrika. This may be but a 

 pale form of N. variegatus. 



Nesoleon punctatissimus (Gerst.) 



From Windhoek, Reitfontein and Reheboth, D. S. W., 

 Afrika, and Lindi, D. O. Afrika. This may be the Myrmeleon 

 lanceolatus Rambr. 



Nesoleon pallens (Klug). 



Several specimens collected by Kristensen in Erythraea 

 I believe are this species; there is some variation in length and 

 breadth of wing and one specimen has the wings about as Klug 

 figures, but the abdomen does not show the transverse dark 

 marks, nor does Klug's description mention them, so I presume 

 the figure is too highly colored in this respect. Klug's species 

 is surely a Nesoleon as he shows plainly in his figure the fine line 

 in the apical venation of the forewings. 



Hagenomyia new genus. 



This genus agrees in general with Myrmeleon ; there are sev- 

 eral crossveins before the radial sector in the hind wings; the 

 spurs are no longer than the first tarsal joint ; which is longer 

 than the second ; the antenna? are wide apart at base ; and there 

 is no line through the apical part of the wings; it differs from 

 Myrmeleon in the much broader wings, in having the radial 

 sector of forewings arising before the cubital fork, and in 

 having many costals before the stigma crossed. 



Type — Myrmeleon tristis Hagen.
