1911] Notes on African Myrmeleonidce 7 



subfalcate at tip, and differ at once from Myrmeleon in having 

 a line through the apical part of each wing, partly formed by 

 the bent branches of the radial sector. 

 Type — N. braunsi Bks. 



1. Wings with large black spots , 2 



Wings with only small black marks 3 



2. Wings almost all black, more than apical half of hind-wings black, only the 



stigma and an apical spot pale braunsi 



Wings mostly pale, less than apical half of hind-wings black, large stigmal 

 and apical spots pale boschimanus 



3. No interantennal mark 4 



Interantennal mark distinct 5 



4. Pronotum with three dark stripes (unnamed species from Kamerun, but one 



specimen) sp. 



5. Pronotal stripes slender and broken; wings rather narrow; a dark spot at the 



base of the stigma, one at end of the cubital fork, and one over cubitus 

 and median near their ends; elsewhere but little marked trivirgatus 



Pronotal stripes plain and complete 6 



G. Wings rather evenly marked all over with small blackish spots at the forks 

 of the veins; the outer gradates not more prominent than other veins, nor 

 a mark at the end of the cubital fork punctatissimus 



Wings not evenly marked all over 7 



7. Wings almost all hyaline, only faintly marked and then most noticeable near 

 the outer apical margin; stigma darker at base pallens 



Wings unevenly marked, the stigma with a prominent dark spot at base, the 

 outer gradates marked, and a pale unmarked streak beyond it, no promi- 

 nent spot at end of cubital fork mysteriosus 



Similar to N. mysteriosus, but the wings not much marked, except at the 

 gradate series, and near the end of the anal vein, thus two oblique lines 

 on each fore- wing; st'gma dark at base; longitudinal veins of wings strong])' 

 marked variegatus 



Nesoleon braunsi Banks. 



I have seen only the types from Willowmore, Cape Colony, 

 (Dr. Brauns). 



Nesoleon boschimanus (Peringuey). 



Head black; a large pale spot each side on face; vertex pale, with 

 black dots, three in each of three rows, median spots sometimes con- 

 nected; pronotum with broad median black, and two narrower stripes 

 each side, the median continued back over the thorax, and the lateral 

 also continued, but in a broken and branched form; abdomen black, 

 some of the segments beyond middle are pale at tip; femora brown; 

 tibia? pale, with a black tip, and on front and middle pair a median band 

 also; tarsi, except basal joint, mostly black; spurs weak, hardly more 

 than one-half the length of the basal tarsal joint. Wings moderately 

 broad, about as in N. mysteriosus; apex acute; venation interrupted 

 black and white; forewings with larger spots along hind and outer 

 margin, a sub-basal spot, a larger oblique median spot, a larger stigmal 

 spot, sloping inward, a spot behind this one; hind wings pale on basal 

 three-fifths; two small spots near disc of wing, then a broad prestigmal 

 band, narrowed in the middle, and broadened behind and reaching out- 

 ward to near tip of wing, a prominent spot beyond the stigma, nearly
