1. Subfamily: Oenochrominae. 
For the general characters of this subfamily the reader is referred to Volume 4 , p. 2 and Volume 12, p. 5 . 
All the veins of the hindwing are developed, the costal (except in Dehos and a few other genera) being free 
or connected with the subcostal by a bar near the base. The 2 nd radial normally arises from the middle of 
the discocellulars, but in Petovia (which should perhaps be ti’ansferred to the Heniitheinae) it arises much more 
anteriorly. Only a few scattered genera are developed in the Aethiopian Region, the most noteworthy being 
the day-flying Aletis group. 
1. Genus: I>ebos Swh. 
Remarkable for having the 2 nd— 3 rd subcostals long-stalked, widely separate from the 4 th, raising 
some doulA as to whether it truly belongs to the Geometridae. Wings narrow, glossy, 2nd radial of the hindwing 
weak. Antenna of G nnipectinate. The type is Indian (see Vol. 12, p. 6, pi. 1 a). The only other known species, 
described below, differs from it in having the 1st subcostal of the forewing running into the costal and the costal 
of the hindwing anastomosing with the subcostal to about the middle of the cell, thus possibly calling for 
generic separation. 
D. purpureofusa Front. Expanse about 16 mm. Head and palpus orange-brown. Body and ^\h\gs, purpurco- 
glossy dark brown or blackish, the wings shot with strong purple reflections — strongest costally on the 
forewing, abdominally on the hindwing and distally on both wings. Portuguese East Africa, only the type 
known. 
2. Genus : Atle^^mobatlira Prout. 
Aspect of Ozola, but with the costal vein of the hindwdng closely approximated to the subcostal near 
the base and without a connecting bar. Face protuberant. Hindtibia of wuth the terminal spurs obsolete; 
5 wuth all spurs. Only one species. Nothing is knowui of the early stages. 
A. ozoloides Prout (la). Similar to a pale, sharply-lined Ozola microniaria Walk. (Vol. 12, pi. 3 d) but ozoloides. 
broader-winged, wuth the apex of the forewung much less produced. White, wuth some browur diisting, the lines 
finely brown. Lindi, Tanganyika Territory. 
3. Genus: Atrophy la Warr. 
Palpus rather short. Antenna of bipectinate, with rather long branches. Legs long and slender; 
hindtibia with all spurs. Forewing wuth apex acute, 1st subcostal anastomosing wuth stalk of 2nd— 5 th to form 
an areole. Hindwing with costal vein closely approximated to subcostal near base, or even anastomosing, 2 nd 
subcostal commonly stalked with 1st radial. Only one species known, exclusively African. 
A. vethi Sn. (— dichordata Warr.) (Ta). White with rather strong grey-brown, ochreous-brown, veilii. 
or reddish-brown irroration, the lines of the forewing fine, sharply-expressed except at the costal margin, the 
gentle, regular curve of 2nd line characteristic. Angola, Uganda, Kenya Colony, Rhodesia, Transvaal, etc. 
I have also before me one example from Senegambia. — meloui suhsp. nov. is more reddish (especially beneath) meloui. 
and has the cell-dots in general better developed. Hindwung less whitened, the line generally very indistinct.
