144. GENUS PROSOMPHAX, WARREN 
Prosomphax. Warren. Ann. S. Afric. Mus. Vol. ro (1), p. 20 (1911). 
Characters. — Face smooth. Palpus very short. Tongue slight. Antenna in (gj bipectinate to 
two-thirds (in Q simple, quieta). Hindtibia in c not dilated, in both sexes with terminal spurs only. 
Abdomen not crested. Frenulum in gf slight, in Q wanting. Forewing triangular, with costa nearly 
straight, shouldered at extreme base and arched distally. apex prominent, termen straight, oblique, cell 
one-half, SC! from cell, anastomosing with C, SC* normal, R! stalked, R? from near apex of cell, 
M!approximated at origin to R?; hindwing with apex and termen rounded, tornus pronounced, 
C approximated to SC for some distance, but not anastomosing, SC? short-stalked with R!. 
Early stages unknown. 
Certainly related to OmpAZax and Rhadinompkax, but distinguished by the absence of median spurs. 
We have not been able to study Warren's type species, but have quoted the characters given by him, 
merely making one or two additions from quieta which will certainly be found applicable. 
Type of the genus : ProsompAhax callista, Warren. 
Geographical distribution of species. — 5. Africa, ? British E, Africa, 
1. P. callisia, Warren. Cape. 
Prosomplax callista, Warren, Ann. S. Afric. Mus. Vol. 10 (1). p. 20 (1911). 
1) The type is a C, not « Q » as described, 
2) Omphax leucocraspeda, nov. sp. — G Q9, 3o-36 mm. Face and palpus crimson, the latter in & minute, in Q nearly equal to 
diameter of eye. Vertex w'ite, tinzed with ochreous, occiput green, side of collar red. Antennal shaft ochreous-whitish proximally, more ochreous distally, 
pectinations in c? ochreous. Legs ochreous below, mostly crimson above. Thorax and base of abdomen green dorsally, abdomen otherwise white,the green 
continuing narrowly (and somewhat interrupted) on dorsum of segments 3-4. Wings bright green, irrorated with whitish; costal edge of forewing narrowly 
pale ochreous; no lines or spots; fringes whitish, slightly tinged with ochreous, their extreme bases mixed with green. Underside slightly paler, costal 
edge of forewiny ochreous as far as SC, in basal balt usually tinged with red, Transvaal: Kranspruit, r9 Dec. 1906 (type C! and 2r Dec. 1906 (G), Riet- 
fontein, 7 Dec. 1904 (Q), Boltfontein, 8 Jan. 1907 (Q), all from A. J. T. Janse; Salisbury. Mashonaland, Aug. 1900 (Q), G. A. K. Marshall; Mashona- 
land (Q) H. B. Dobbie. All these specimens are in coll. Brit. Mus. Also a Q from Kranspruit, 22 Dec. 1906, in coll. L. B. Prout, and one from Pretoria, 
5 Dec. 1907, in coll. A. J. T. Janse. In one exanple SC! of forewing is free; in the rest it anastomoses with C, in three also with SC?. The structure is 
typical, except in the absence of crests; DC? of both wings excessively oblique.
