NOTES ON AFRICAN MYRMELEONIDjE. 



By Nathan Banks. 



The following article is based largely on the collection of 

 African Myrmeleonidas of the Berlin Museum, which the cura- 

 tor, Dr. R. Heymons, wished me to work out for them. Mr. 

 Esben Petersen has kindly loaned me his collection of Abyssin- 

 ian Myrmeleonida?, which contains several species previ- 

 ously unknown to me. My own collection contains a num- 

 ber of species, principally from South Africa from Dr. H. 

 Brauns' duplicates from the Petersen collection, and material 

 purchased from dealers. 



There are many other species recorded from Africa. Some 

 of these are probably synonyms of well-known species. I have 

 made a new arrangement of the genera, and given tables to 

 species as far as possible. 



Much of the Berlin Museum material is from German East 

 Africa (D. O. Afrika), but many valuable specimens are from Ger- 

 man Southwest Africa (D. S. W. Afrika), from Kamerun and 

 Togoland. 



The types of the new species, except where otherwise indi- 

 cated are in the Berlin Museum. 



TABLE OF GENERA OF AFRICAN MYRMELEONIDA. 



1. In the hind wings but one (rarely two) cross-veins before the origin of the 



radial sector; the anal usually ends in the margin (Dendroleonins).. . .11 



In the hind wings four or more cross-veins before the origin of the radial 



sector; the anal often runs into the cubital fork (Myrmeleoninae) 2 



2. In the hind wings the anal is not connected directly to the hind margin by 



cross-veins, but to the post-anal by a series of cross veins; wings heavily 



marked; pronotum very much broader than long (Palparini) 3 



In hind-wings the anal vein is connected directly to the hind-margin by several 

 cross-veins (Myrmeleonini) tj 



3. Two or more series of costal cells nearly to the base of wing Stenares 



But one series of costals, except near the stigma -1 



4. Apex of subcosta incrassate ... Pamexis 



Apex of subcosta not incrassate o
