beyond and at tip darker brown; pronotum broader than long, yellowish, 

 with two broad black stripes and the lower margins black; rest of thorax 

 pale, striped and spotted with black, scutelli mostly pale, the mark 

 over base of the forewings includes two pale spots; abdomen shorter 

 than wings, brownish, paler on basal half and there with lateral black 

 line; legs pale, anterior femora and tibiae dotted with black, tip of tarsi 

 black, apical joint of tarsus nearly as long as others together, spurs about 

 as long as four joints. Wings hyaline, stigma rosy, longitudinal veins 

 black and white, radial sector and branches and most of the crossveins 

 black. Wings rather broad beyond middle, tips acute, hind wings sub- 

 falcate; S crossveins before radial sector in forewing, two in hindwing, 

 13 branches of radial sector in both wings. 

 Expanse 85 mm. 



From Langenburg, D. O. Afrika. In general similar to 

 F. lethalis, having broad wings and slender antennae, but the 

 two crossveins before radial sector in hindwing distinguish it. 



Formicaleon ilione n. sp. 



Face pale, a vertical black line between bases of antenna?; a broad 

 deep black band above antenna' ; two, rather curved, bands on the vertex, 

 connected in middle by dark, and the posterior one extended behind 

 in middle; pronotum with a broad black median stripe, broken up 

 1 lehind into lateral projections, a spot each side near front on the trans- 

 verse groove, and the posterior sides black; rest of thorax mostly black, 

 with a broad pale stripe each side, sides of scutelli pale; abdomen black, 

 each segment (beyond the basal) with a pale stripe each side, connected in 

 front of the dorsum, venter rather pale, the pleurae of thorax heavily 

 streaked with black, leg Short, hairy; femora thick, with many white 

 hairs and bristles and a few black ones, anterior femora mostly black, 

 others paler, especially below, front and middle tibiae with two black 

 bands, hardly visible in hind tibia?, tarsal joints tipped with black, very 

 short, the basal especially so, the fifth as long as all others together, 

 spurs longer than three joints. Wings with the longitudinal veins 

 heavily marked with black and white, the costals and many crossveins 

 mostly black, black spot at base of stigma, a long curved prominent 

 black stripe over the gradates toward tip of wing, and a short, oblique 

 mark upward from near the end of the anal vein; hindwings less marked, 

 the anal vein wholly, and the median vein on the basal third very pale 

 yellowish, other veins marked slightly with black. Wings not very 

 long, quite broad at stigma, hind pair much narrower, both pairs acute 

 and subfalcate at tip, the outer margin being slightly concave, seven 

 cross-veins before origin of the radial sector in the forewings, ten to 

 eleven branches of the radial sector in each wing. 



Expanse GO to 65 mm.
