1911] Notes on African Myrmeleonidce 13 



Gymnoleon exilis n. sp. 



Face pale yellow, a large black interantennal mark, a row of spots 

 across the vertex, the middle one the largest; pronotum pale yellowish, 

 a pair of black submedian stripes, not quite parallel, and a lateral stripe 

 each side; rest of thorax pale, with a pair of dark submedian lines, 

 broken, but extending over the scutelli, a lateral dark line over base of 

 wings; abdomen rather pale, with dark stripe on each upper side; legs 

 pale, middle and apical mark on tibia?, except the hind tibiae have only 

 the apical mark, tips of tarsal joints black. Wings hyaline, venation 

 mostly brown, but the longitudinal veins are interrupted with pale, 

 many of the cross-veins with a pale dot or space; many of the forks in 

 posterior and outer part of fore-wings have a black dot, a larger spot 

 near end of anal vein, and faintly dark at anastomosis of cubitus and 

 median, this last mark is more prominent in the hind-wings, often 

 elongate. Wings rather slender, acute at tips, the hind pair plainly 

 longer than the forewings, narrower and subfalcate at tips; about seven 

 crossveins before radial sector in forewings, about S branches of radial 

 sector in each wing, in forewings the anal vein ends before the origin of 

 first branch of radial sector, and the forks of cubitus are plainly diver- 

 gent. The pronotum is longer than broad, and broadest behind; the 

 abdomen is much shorter than the wings. 



Expanse 45 mm.

Gymnoleon elizabethae n. sp. 



Face yellow, a black band below the antennae reaching above them, 

 the vertex broadly rounded in front and dark brown, back of vertex 

 gray, with two rows of blackish dots, front of vertex with a median furrow 

 making the front plainly bilobed; antennae brown, tip paler, pronotum 

 short, dull blackish, a faint paler spot each side in front, and one or two 

 in the middle; thorax brown, indistinctly marked with pale; a deep 

 black band on metanotum; abdomen blackish; legs short, yellow-brown, 

 with black marks on tibiae, hind tibia only at tip, tarsi mostly dark 

 brown, except the basal joint of hind tarsus which is yellow; no spurs; 

 basal joint of tarsus as long as second and third together. Wings with 

 black and white venation, on radius the black and white are in long 

 streaks, elsewhere in short spots, along cubitus and its fork are several 

 small clouds of brown, and a longer oblique mark on cubitus and median 

 near their tip, stigma dark at base, and a cloud near end of anal and 

 cubital fork. Wings slender, subfalcate at tips, anal and cubital fork 

 in forewings run parallel for a distance longer than width of wing, the 

 cubital fork nearly parallel to the cubitus; twelve branches of radial 

 sector in each wing; in apical part of wings the longitudinal veins are 

 very close together. 



Expanse 52 mm.
