HEMISTOLA; LOPHOSTOLA. By L. B. Prout. 
4 :} 
0. delicata Warr. differs chiefly from vivida in having a slender dark terminal line, interrupted at (teUcala. 
the vein-ends by large white dots, the fringe whitish, with rather large grey spots opi)osit6 the vein-ends. The 
face is perhaps less red and the $ palpus a trifle longer still. Natal (type), S. Mozamlhcpie and Kenya Colony. 
0. punctilineata Warr. (4 h) scarcely differs constantly from delicata except in having the white dots pund.i- 
which represent the two lines (or at least the postmedian) accompanied by larger dark dots. Terminal line and 
dots generally slighter, the spots on the fringe connected by a reddish line. Perhaps both are forms of one 
species, 'punctilineata commonest in the d', delicata in the 5. Cape to S. Rhodesia. 
0. minima Prout. Smaller than the other species (lb mm); probably nearest to delicata. Rather bluer minima. 
green, terminal white vein-dots present, but no dark line; fringe similarly spotted. Abdominal white spots not 
red-edged. Nigeria. 
67. Genus: Heiiiistola Warr. 
Palpus variable in length, generally quite short. Antenna pectinate in the (d and usually in the $. 
Thorax beneath hairy. Abdomen not crested. Hindtibia with all spurs, rarely with hair-pencil. Wings ample, 
densely scaled, the hindwing typically with a blunt or a sharp angle at the 3rd radial. Venation normal, the 
costal of the hindvdng not anastomosing with the cell. A rather heterogeneous assemblage of Old-World 
species (see Vol. 4, p. 30). 
H. ( ?) ereuthopeza Profit (4i). Palpus short and slender. Tongue rudimentary. Antenna in ereuthopeza. 
pectinate. Narrower winged than true Hemistola, probably related to Eucrostes rujociliaria H.-Sch. but with 
4-spurred hindtibia. Forewing nearly as in that species, hindwing whitish. unknown. Orange Free State. 
H. (?) incommoda Prout (4i). Wings broader than in ereuthopeza. Tongue developed. Otherwise Incommoda. 
nearly akin to that species. The hindwing, proximally whitish and distally more green in fresh specimens, 
discolours through moisture to a rather bright ochreous. Described from Transkei (Cape Colony), subsequently 
obtained by Prof. Janse from Rietviel, Natal. 
H.hypnopoea Prout (4 h) differs from all the other Hemistola in its didl, pale yellow-green colour, hypnopoea. 
which recalls Nothoterpna or Acollesis. Palpus slender, a little longer than diameter of eye. Antenna in d' vith 
the pectinations short, in $ not pectinate. Hindtibia in E with a hair-pencil. Madagascar. 
H. albifimbria Warr. (4 i), founded on a $ from Nyasaland, was described as a Thalassodes and albifimbria. 
transferred, according to the discocellulars of the hindwing, to Prasinocyma, but proves to have no frenulum 
in the cj and is probably a Hemistola with non-pectinate $ antenna. It is of a lighter, more yellowish green than 
the similar species of Prasinocyma. Very widely distribixted: E. Africa, Uganda, N.E. Congo, Nigeria, Senegal. 
H. tricolorifrons Prout recalls a still broader winged Prasinocyma ampla except in the minute palpus 
and absence of (J frenulum. Face red above, strongly mixed with green in middle, white below. Wings thinly 
scaled, strigulated as in Prasinocyma, without markings; hindwing rounded. Mount Kenya, W. slopes (type) 
and Lamu Islaird. 
68. Genus : I^opliostola Prout 
A very natural genus, showing the rare combination of strongly developed abdominal crests with loss 
of frenulum in both sexes. Palpus in shortish, in $ longer. Antenna in both sexes simple. Hindtibia in both 
sexes with terminal spurs only. Forewing with all the subcostals on a common stalk. Exclusively African. 
L. atridisca Warr. differs from the other species in having the hindwing less bent. Cell-spots black- 
brown; terminal line obsolete; fringe unspotted. Natal; also from Pondoland, Transvaal and S. Mozambique. 
-- cumatilis Prout (41) from Madagascar, is of a bluer green, the cell-spots larger, wliite vein-dots better cumatilis. 
developed, terminal white dots also present on the veins. — dummeri subsp. n. expands 29 mm, is brighter green dummeri. 
and has the cell-spots at least as small as in atridisca, but of a reddish colour, and the hindw ing begins to make 
some approach in shape to that of cara, which may possibly prove a further race of the same species. Uganda: 
Mulange, Jinja, May 1922 (R. A. Dummeb), type E Mus. Tring. A d' from Nairobi in coll. Joicey. 
L. cara Prout has nearly the shape of annuligera (41) but is smaller, a little brighter green, cell-spots cara. 
red, scarcely pale-centred, terminal line weaker, fringe more yellowish, with its spots redder, costal margin 
of forewing not dark-spotted. Nigeria (type). Ivory Coast and W. Kivu. The less small size and plain green 
fringe differentiate all the races of atridisca from it. 
L. annuligera Sivinh. (4 1). Readily recognized by its conspicuous dark terminal line and whitish, dark- annuligera. 
spotted fringes; costal margin of forewing with dark strigulae. Uganda. Also known from French Guinea, 
Gold Coast, Ashanti, Nigeria, Cameroons and possibly Nyasa.
