E. mfociliaria H.-Sch. (= roseata Warr.) (5 cl). Hitherto placed here, but probably requires a separate rKfocil'taria. 
genus, not only on account of the elongate wings and their relatively long cells, but also of its short palpus, even 
in the $, and aborted tongue. Cape, rare. 
77. Geiitis: Alloclirostes Prouf 
An exclusively African genus, diffeiing ivom Eucrostes principally in that the costal vein of the hindwing 
anastomoses very strongly with the subcostal, often nearly to the end of the cell. Abdomen with white, dorsal 
spots, generally in part surrounded with red. 
A. impiinctata Warr. (= imbridentata Warr.) (4 k). Very similar to saliata (4 1) hut with the cell-dcjts i)»p><»dnfa. 
white, not red, the white lines fairly well developed though very fine. Very widely distributed in Africa south 
of the Sahara, though I have no record for Cape Colony. The type locality is IMombasa Island. 
A. saliata 7<'eW. (4 1) is rarer than the preceding and much more restricted in its range. Natal (type) saliata. 
to Tanganyika Territory. 
A. biornata Prout (4 k) is smaller, the forewing narrower and with broadly rosy, white-mixed costal hiornata. 
border; both wings with white, red-ringed cell-spot and with red, white-spotted border. Natal (type) to 
S. Rhodesia. 
A. imperfecta Prout (5 d). At least as small as hiornata (14 mm). Face green. Wings green, scarcely imperfecta. 
so bright as in saliata, entirely without red markings, the lines greenish white, very fine. Transvaal; Warm- 
berg, 1 o . The hindlegs are wanting in the unique type, but the rest of the structure agress well with AUochrostes. 
78. Genus : Alloclilorodes Prout 
Tongue more vestigial than in AUochrostes, or perhaps wanting. Antenna of $ perhaps merely serrate 
(not certainly known). Vtings more elongate, the forewing more triangular; hindwing with costal vein 
anastomosing to scarcely cell; both wings rvith 1st median widely separate at origin from 3rd radial. Ab¬ 
domen without dorsal pattern; hindwing white. Erected for a single species which does not conform well either 
to AUochrostes or to Xenochlorodes and has more the shape and facies of Chlorosterrha. 
A. elpis Prout (5 d). Smaller than Chlorosterrha semialha (2 g) rather brighter and less bluish green and etpis. 
differing in the structural characters — 2-spurred hindtibia, anastomosis of costal vein of hindwrng and others. 
Cape of Good Hope. 
79. Genus: Xenochlorodes Warr. 
Distinguished from Syncollesis by the absence of the proximal spurs of the hindtibia. See further 
Vol. 4, p. 34. To the three Palearctic species there has subsequently been added one South African. 
X. xina Prout (5 d). Less vivid green than beryllaria Mann, the lines faint. Differs structurally in the xina. 
still more minute palpus, apparent absence of tongue, rather shorter anastomosis of the costal vein of the 
hindwing and wide sej)aration of the 1st median of liotli wings. Transvaal (type), Tanganyika and Natal. 
80. Genus: Acitlaliaistiii^ limps. 
Differs chiefly from Xenochlorodes in the narrower wings and different colour-scheme, the hindwing 
being generally white, the forewing oftenest brown. Antenna of $ generally pectinate. Costal of hindAHng 
anastomosing to near end of cell. The wing-shape, coloration and nearly central position of the 2nd radial 
superficially suggest Sterrhinae. The discovery of the (JG of suhhrunnescens and hicurvifera, wiiich were founded 
on $$, has shown that the genus is not a very natural one, for they are evidently derived, by the loss of the 
frenulum, from a form cognate to Hemidromodes. All the species are African. 
A. A hindtibia simple, wA t h 2 spurs. 
A. (?) porphyretica Prout (4k) is placed here jjrovisionally, biit its systematic position is doubtful, porphijre- 
$ antenna not pectinate. Hindwing not paler than forewing. Madagascar. 
A. (?) prophanes Prout is also aberrant in the non-pectinate P antenna, but more normal in colouring, prophanes. 
Expanse 16 mm. The only known G is brownish drab, AAoth very fine pale edges to the slightly darker central 
area. $ white, slightly tinged with buff, especially at costa; lines black-brown, on forewing thickened anteriorly,
