C. eucela Prout. Expanse 21 mm. Hindtibia of cJ dilated. Antennal shaft white, spotted with red. 
Fore wing with 1st subcostal anastomosing with costal. Colour of didida, but with the cell-dots darker green, 
not brown. Face brighter red than in the most similar Prasinocyma {scissaria, tranquilla), palpus shorter. 
Pretoria, only the tyjDe cj known. 
C. clopia Prout (4a). Still more similar to Prasinocyma, the wings being a little broader than in the 
two preceding, rather more bluish green and with very fine whitish strigulae. Antennal shaft not spotted with 
red. Cell-spots scarcely darkened. Pretoria North. 
C. dilatata Walh., ostensibly from South Africa (Dr. Andrew Smith) is almost certainly Australian, 
apparently indistinguishable from a worn $ of assimilis T. P. Lnc. Macleay went to Tasmania in 1839 and 
was working out his insects at the same time to which Walker’s type is assigned, so that some confusion of 
labelling may have occured. 
36. Genus: Heteroracliis Warr. 
Perhaps a section of Omphax. Palpus similarly minute, the wings often equally devoid of markings, 
the only constant difference is that the antenna of the $, as well as that of the (J, is pectinate. Abdomen with 
or without crests. Hindtibia with 4 spurs. Hindwing generally rounded; 1st median well separate or {melano- 
phrag7na and the subsequent species as far as tornata) often stalked. Entirely African. 
H. insueta Profit (5 c) is an anomalous species, with the palpus scarcely so short as in true Pieter or achis, 
the wings with the iridescence and markings of an lodis. Crests bordered with orange-red. Wings grey-green 
with purplish reflections or in the only known $ almost entirely purple. Diego Suarez, Madagascar. 
d A 
H. asyllaria Sivinh. is possibly a form of diaphana (A-^r), but is generally larger, with the inner margin 
of the hindwing relatively longer. Terminal dots very slight, the cell-dots, on the other hand, well developed. 
Venation as in diaphana. Madagascar. 
H. diaphana Warr. (4 a) resembles a Prasinocyma in its colour and short white strigulae, but differs 
in the very short palpus and pectinate $ antenna. Face red. Crests slight. Both wings with 1st median widely 
separate. Cell-dots small but sharply black. Minute terminal dots, sometimes visible only with the lens. 
IMadagascar. 
H. malachitica Saalm. (2 i). A pretty species, the lines marked by white vein spots, the terminal line 
lilackish, the fringes tippeil with brown, otherwise white with sharp dark spots at the veins. Madagascar. 
H. trita Prout (4 a). Much smaller, much deeper green, without markings except at the termen, 
whicli bears pnre white, dark-edged lunules; costal edge reddish; fringes rosy, proximally mixed with black. 
Diego Suarez. Like the devocata group but with the 1st median of both wings separate. 
H. dichorda Prout (3 k). Very distinct in its bright green colouring and strongly marked lines. Crests 
red-brown. Widely distributed: Senegal, S. Sudan, Uganda, Keyna and Tanganyika, the type from the last- 
named locality. 
H. prouti B.-Baker (3 k). Much paler, more delicate green, really white with dense green irroration. 
Abdominal crests white, forming a ridge. Both wings with the 1st median arising close to the 3rd radial; the 
white lines finely edged in median area with bright yellow. Angola (type), Rhodesia, Gold Coast, Bahr-el- 
Ghazal, Kenya, Angoniland. 
H. perviridis Prout. Expanse 37 mm. Bright, opaque green as in Omphax, which indeed it altogether 
resembles except in the C antenna, which has strong pectinations, the proximal ones over twice the diameter 
of the (very liroad) shaft. The is still unknown, perhaps not distinguished from the following. Face purple- 
red. Abdomen above concolorous with wings. Fringes green, at the tips whitish. Transvaal: Pretoria. 
H. simpHcissima Prout (3 k). Rather smaller ($ 33 mm), pectinations in 4 or 5 times width of shaft, 
in $ scarcely 1. Tip of abdomen and of fringes white. Both wings with costal margin slightly less elongate then 
in pterviridis. Transvaal and Natal. 
H. simplex Warr. (= haploa Prout) (4 a). Extremely similar to simpHcissima. Pectinations of the ^ 
antenna about 3 times the diameter of the shaft; those of the $ about twice the diameter of the shaft. The 
wings are of a rather less deep and bright green than in simpHcissima, but it is difficult to obtain unfaded 
specimens. It Yevy ^tron^y vecdiWii Omphax leucocraspeda Prout (4 b) but is bluer green, vuth the frings green 
proximally. Described from the Kikuyu Escarpment. Specimens from Nyasa and Rhodesia, which I have 
doubtfully referred here, seem to have somewhat shorter pectinations in both sexes.
