dot; costal edge and terminal line rosy, coarsely irrorated 
with blackish fuscous; fringe proximally rosy. 
Hind wing with tail shorter than in the other species; as

Underside whitish green, the borderings fainter and duller 
than above. 
Udamba, Kuila River, 8.W. Congo State (J. S. Bousfield). 
19. Thalassodes floccosa, sp. n. 
(Pl. VII. fig. 4.) 
3 .—44 mm. 
Face green. Palpus with third joint elongate. Vertex 
and base of antennal shaft white. Thorax and abdomen 
green ; abdomen beneath strongly pilose. Hind tibia densely 
clothed with long, golden-brown, floccous hair; tarsus not 
shortened, with similar clothing on the first joint, becoming 
progressively shorter on the second and third joints. 
Fore wing green (faded), with the usual white postmedian 
line almost straight, placed at about 6 mm. from termen, 
chiefly marked as dots on the veins ; termen with a fine dark 
line, darker-dotted on the veins; fringe whitish (defective). 
Hind wing elongate, with the angle at R® well marked ; a 
somewhat raised white cell-mark on DC*, nearly as pro- 
nounced as in Hretmopus marinaria, Guen., more elongate ; 
postmedian line of the normal form, chiefly marked as white 
vein-dots; termen as on fore wing; beneath clothed to 
beyond middle with floccous light brown hair. 
Prov. Wellesley, Malay Peninsula (Distant). 
Probably near lewcospilota, Moore, suggesting an interesting 
transition towards Hretmopus marinaria, Guen. 
20. Prasinocyma rhodocycla, sp. n. 
(PI. VII. fig. 6.) 
9 —37 mm. 
Palpus slightly over twice as long as diameter of shaft, 
second joint reaching beyond frons, third joint longer than 
second. Like oculata, Prout (Nov. Zool. xxii. p. 316), from 
Uganda, but with the face reddish, somewhat mixed with 
green, the wings broader, with rather more rounded termen, 
the white strigulation less strongly developed, a small white 
spot beyond middle of hind margin of fore wing. The fringe 
—green in the proximal part—is greyer and rather paler in 
the distal.
