Rhadinomphax, nov. gen. Prout. 
Omphacodes (part.). Warren, Novit. Zool. Vol. r, p. 396 (1894) (nec sect. typ.). 
Characters. — Face smooth. Palpus in both sexes small (scarcely as long as diameter of eye), 
second joint shortly scaled, third joint not elongate. Tongue present. Antenna in Cf subdentate, or 
with strong, clawed teeth, shortly ciliated, in Q minutely ciliated. Pectus slightly hairy. Femora 
glabrous. Hindtibia in cf not dilated, in both sexes with all spurs. Abdomen not crested. Frenulum 
in gf arising from before basal expansion, in Q wanting. Forewing triangular, rather narrow, costa 
nearly straight, apex moderately acute, termen nearly straight, oblique, cell about one-half, DC? deeply 
incurved, very oblique posteriorly, SC! from near end of cell, anastomosing quickly with C, SC? nor- 
mal, anastomosing strongly with SC! and quite exceptionally also with SC**, R! connate or short- 
stalked, R? from above middle of DC, M! well separate; hindwing with costa long, apex rounded, 
termen rather straight, tornus moderate, cell about one-half, DC? deeply inbent (usually inangled), 
strongly oblique below, C anastomosing to near end of cell, SC? stalked, R? very characteristic, M! well 
separate. 
Early stages unknown. 
Nearly akin to Dichroma, but of somewhat more slender build, with SC? of forewing normal, and 
with non-pectinate cf antenna. Warren evidently drew up his characterization of Omfhacodes from this 
genus, but chose as type directa, Walker, which is abundantly distinct and must of course bear the 
name.

1) Prosomphax (?) quieta, nov. Sp. — 9,35 mm. Face and palpus ochreous red, paler below. Vertex green, paler between antenne 
Antenna pale ochreous, Thorax pale green above. Legs pale ochreous. Abdomen white. Forewing pale green, unmarked; costal edge narrowly pale 
ochreous ; fringe pale green in proximal half, white in distal. Hindwing greenish white, unmarked Underside white, of forewing slightly tinged with 
green, especially in costal half; costa of forewing as above. Machnkos, British E. Africa, 7 July, 1898 (R. C. Crawshay). Type in coll. Brit. Mus. Placed 
provisionally in this genus; the costa of forewing may be slightly more arched ; the cells are shorter, hence there are more stalkings, SC! of forewing being 
shortly stalked (t rough still arising before R!), M! of both wings stalked and SC? of hindwing longer-stalked ; SC! of forewing does not anastomose with C.
