1911] Notes on African Myrtneleonida 19 



Formicaleon persephone n. sp. 



Face pale yellow, a black band below antenna? and one above, two 

 transverse rows of spots on the vertex; antennae pale, annulate with 

 with brown; pronotum broader than long, dull blackish, a faint median 

 pale line and an indistinct outer pale stripe each side; rest of thorax 

 dark, marked a little with pale, posterior margin of anterior lobe of 

 mesothorax pale; abdomen blackish, a pale spot above before middle of 

 each segment; legs pale, hind femora and tibias with blackish dots, 

 front femora darker, tibia; with basal and apical dark mark, and tips of 

 tarsi black; apical joint of tarsus not as long as the others together, 

 spurs as long as four joints, curved. Wings extremely slender, fully 

 six times as long as broad, acute at tips; venation mostly black, the 

 radius mostly pale, the subcosta interrupted black and white, cubitus 

 with longer streaks of black and white, cross-veins on large patches are 

 pale, the gradates black, a black spot at base of stigma and over union 

 of subcosta and radius; 7 crossveins before radial sector in forewings, 

 about 11 branches of radial sector in each wing. 



Expanse 50 mm. 



From Thies, Senegal. Its small size and very narrow wings 

 separate it from all others. 



Formicaleon hesione n. sp. 



Face pale, a black band below and one above antenna?, pale between, 

 vertex brown, three double black spots behind in a transverse row, and 

 in front of these are two others, submedian; antennas pale, annulate with 

 brown; pronotum broader than long, dark, a median pale line, and a 

 large anterior spot each side, not clearly outlined, but reaching backward; 

 rest of thorax dark, marked with pale, especially on the scutelli; legs 

 short, pale, tibia? marked with brown above near base and at tip, tips 

 of tarsi dark, dark dots on hind femora, black hairs below on femora 

 and tibia? I, tarsi short, apical joint about as long as others together, 

 spurs as long as four joints, curved; abdomen shorter than wings, 

 blackish, a pale spot above before the middle of each segment, apical 

 segment with a pale spot each side near tip. Wings hyaline, venation 

 black and white, some large patches of white veins, costals black at 

 each end, four spots behind radius, < me before radial sector, one on origin 

 of radial sector, one on first branch of radial sector, and one near stigma, 

 the stigma with basal black mark, and a spot on radius beyond, a short 

 oblique mark over end of anal vein, and the outer gradates plainly 

 black, also a spot over the first crossvein between cubitus and cubital 

 fork; in hind wings a spot at base of stigma, one just behind radius near 

 by, and one on radius beyond stigma. Wings very slender, acute at 

 tips, 7 cross veins before radial sector in forewings, about 10 branches 

 of radial sector in both pairs. 



Expanse 58 mm. 



From Nssanakang, Kamerun. In general appearance it is 

 very much like Nemoleon J^-maculatus from East Africa, but the 

 gradates are more plainly marked, and the tarsi are very 

 different in structure.
