124 Mr. L. B. Prout on new 



Fore wing rather sliort and broad ; very pale green, tlie 

 costal edge pale oclireous, more broadly at base ; anteinedian 

 line wanting; postniedian slender^ oclireous whito, from hind 

 margin at about three-fourths, obsolescent fiom 11^ forward; 

 terminal line and fringe whiter. 



Hind wing with abdominal margin relatively long, terraen 

 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 Hue weaker ; hind 

 wing somewhat whiter, the line weakly iudicated. 



Gambia {A. Moloney^. 



Closely similar to N. carnifrons, Butl., the only non- 

 African species of the genus. 



25. Nturotoca insolens, sp. n. 

 (PI. VII. tig. 19.) 



(^ . — 33 ram. 



Face red. Palpus extremely minute, red. A short tongue 

 present. Vertex and proximal part of aiitennal shaft red; 

 occiput green. Antennal pectinations about twice as long as 

 diameter of shaft. Thorax above green ; abdomen dirty 

 wliitisli oclireous, with dark belts (possibly discoloured), crests 

 slight. Underside whitish. Fore leg marked with red on 

 upper and inner side. 



Fore loing less pointed than in the typical species ; M^ 

 connate; green, as in Htteroracliis simplex, Warr. {Jiaploa, 

 Prout) ; costal margin red at base ; cell-mark faintly darker 

 green ; fringe white. 



Ilind wing more rounded than in the typical species ; C 

 anastomosing with SC at a point near the base, then diver- 

 ging, ]\F shortly stalked ; as tore wing, except costal margin. 



Underside almost uniform whitish green ; fore Aving with 

 costal margin oclireous, at base reddish, the costal and apical 

 regions slightly greener than the rest of the wing. 



Victoria Falls, Rhodesia {E. H. Druce'), type and another. 



Placed provisionally in Ji'eurotoca, as it would fall there by 

 my keys (Gen. Ins. fasc. 129, p. 14; Nov. Zool. xx. p. 43-1), 

 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. 



2&. Proliydata ignita, sp. n. 

 (Pl.'VII. fig. 10.)

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