4. Subfamily: Larentiinae. 
Of this subfamily, as of the preceding, a faiily comprehensive account has l)een given in connection 
with the Palaearctic fauna (see Vol. 4, p. 152). It was formerly considered to be very ])oorly represented in 
the African Region, but the exploration of the higher mountains has yielded many interesting additions; 
for instance, the “Voyage de Ch. Alluaud et R. Jeannel en Afrique Orientale,” of which the Geontetridae 
have been recently worked out (Mem. Soc. Zool. Fr. Vol. 39, fasc. 5), has shown just over one-third of 
the represented species to belong to the Liirentiina^ and almost one-third of the forms in this subfamily to 
be new. The late Mr. T. A. Barns also made many valuable discoveries and every visit to the higher alti¬ 
tudes of Kilimandjaro, Kenya and Ruwenzori will surely reveal others. At the same time, our definition 
of the subfamily as consisting of “s mall or moderate-sized moths” is probably even more exactly apy)lic- 
able to Africa than to any other region; there is nothing here to a])proach the Triphosa of the Himalayas 
in size or the Callipia of South America in combined size and gaiety of colouring. 
In brief, the subfamily is best distinguished by its venation: forewing with 12 veins, almost in¬ 
variably with one or two areoles, 1st discocellular very short or wanting, 2nd radial ])retty normally ]daced; 
hindwing with cell more or less shortened, costal vein anastomosing strongly with it or (in some of the 
Lobophom group) connected by a bar nea end of cell. Rarttern, at least of forewing, generally consisting 
of a large number of lines, commonly more or less grou])ed into bands. Tongue, hindtibial spurs and fremdum 
nearly always normally developed. genitalia with gnathos vestigial or wanting, anellus lobes and juxta 
generally with special developments. 
1. Genus: lilois Hb. 
A large genus, of somewhat doid)tful position, but having evident affinities with the Slerrhinae, to 
which it may eventually need to be transferred. But for these affinities, its high degree of specialisation 
wnuld have involved our placing it at the end, with the Hydrelia group. Face smooth. Palpus short. 
Tongue developed. Legs simple. Both wings with cell short; forewing with areole generally small, occasionally 
wanting, all the subcostals stalked, the 5th separating before the 1st, 1st discocellular well developed; 
hindwdng with costal anastomosing strongly, 2 nd subcostal stalked, 1st median stalked. The genitalia have 
been little investigated but suggest — like the forewing — a possible relationship to Anisodes. Ohiefly South 
American; a sprinkling of species in the Indo-Australian and African regions. 
A. Antenna in 1) o t h sexes simple. 
E. oressigenes Front (9 a). Areole fairly large, hindwing exce])tional in having the 1 st median not oresshjoies 
stalked. Easily known also by its yellow wdngs, with rust-red reticulation. Kivu: Nirogongo Volcano, 
2800 m. 
E. anisorrhopa sp. n. (9 a). Expanse 17—20 mm. White, with black cell-dots and terminal dashes anisor- 
and a characteristic pattern of irregidar lines, alternately thick (and brown) and very slender or ])unctiform rhopa 
(more fuscous), the median of the forewing extremely bent round the cell-dot. Underside more weakly marked.

E. innocens Warr. (9a). Less small, hindwing more angled; more suffused, wdth the median area innoccns. 
of the forewing darkened into a band; terminal dashes small and w'eak. Areole wanting. Kikuyu Escarpment. 
E. alticola Avriv. (lOa). Rather variable in size and in the ground-colour, which may be either altkola. 
red-brown, as in the type, or dusk}^ drab, as in the specimen here figured. Areole w'anting. Retinacidum 
weak. Antenna of ^ lamellate, v/ith very short ciliation; otherwise very suggestive, both in shape and mark¬ 
ings, of some South American species of the section Gainbogia Guen., in which the A L strongly jiectinate.

B. A n t e n n a in both sexes 1) i ]) e c t i n a t e with strong 1) r a n c h. e s (P s e u - 
d a s t h e n a Moor e). 
E. grataria Walk. (= pallicinctaria Walk.) (9 a). Extremely variable in coloration — dull purple, grafaria. 
rosy or even somewhat ochreous, only with slight purplish suffusions in the median area —, but generally 
recognizable by its shape, its nearly clear yellow fringes and, at least on the forewing, yellow' outer spots 
between the radials. Areole generally wanting. Several aberrations have been named from the Indo-Austra- 
lian Region, where it has an enormoiis distribution, and these will be described in Vol. 12. — ab. medio- mediofusca. 
fusca Profit, described from Pondoland, is a rare form with a complete dark median band. Known African 
localities for grataria are Nigeria to Angola, Uganda, Kenya Colony and Natal; WAiiKER’s type was from 
Ceylon.
