Fore wing rather short and broad; very pale green, the 
costal edge pale ochreous, more broadly at base ; antemedian 
line wanting ; postmedian slender, ochreous white, from hind 
margin at about three-fourths, obsolescent from R? forward ; 
terminal line and fringe whiter. 
Hind wing with abdominal margin relatively long, termen 
strongly rounded in posterior part; line of fore wing con- 
tinued, farther from termen, weak at abdominal margin. 
Fore wing beneath nearly as above, the line weaker ; hind 
wing somewhat whiter, the line weakly indicated. 
Gambia (A. Moloney). 
Closely similar to V. carnifrons, Butl., the only non- 
African species of the genus. 
25. Neurotoca insolens, sp. n. 
(Pl. VIL. fig. 19.) 
3 .—33 mm. 
Face red. Palpus extremely minute, red. A short tongue 
present. Vertex and proximal part of antennal shaft red; 
occiput green. Antennal pectinations about twice as long as 
diameter of shaft. Thorax above green; abdomen dirty 
whitish ochreous, with dark belts (possibly discoloured), crests 
slight. Underside whitish. Fore leg marked with red on 
upper and inner side. 
Fore wing less pointed than in the typical species ; M! 
connate; green, as in Heterorachis simplex, Warr. (haploa, 
Prout) ; costal margin red at base; cell-mark faintly darker 
green; fringe white. 
Hind wing more rounded than in the typical species; C 
anastomosing with SC at a point near the base, then diver- 
ging, M' shortly stalked; as fore wing, except costal margin. 
Underside almost uniform whitish green ; fore wing with 
costal margin ochreous, at base reddish, the costal and apical 
regions slightly greener than the rest of the wing. 
Victoria Falls, Rhodesia (L. H. Druce), type and another. 
Placed provisionally in Vewrotoca, as it would fall there by 
my keys (Gen. Ins. fase. 129, p. 14; Nov. Zool. xx. p. 434), 
but probably requiring a new genus. ‘There can be little 
doubt it is a direct development of Heterorachis, with the. 
median spurs of the hind tibia wanting. 
26. Prohydata ignita, sp. n. 
(Pi. Vil. figs 10:)

Face white, with a tinge of yellow, the upper part light
