witli brown. Structure similar, the palpus perhaps a little stronger. Somewhat suggestive of an Entephria, 
as which Wabken described it. C^ape Colony. 
0. petrogenes Prout (9f). Although our figure is slightly too broad-winged, this sjiecies, like africana, 
presents little of the aspect of tyjucal Orfholitha. ^ antenna with the lamellation deeper than in the two preced¬ 
ing. Forewing more slate-grey, without the brown admixture; sidherminal line broken into white spots (in 
africana forming coimected lumdes); fringe cheqiiered, as also in africana, but in that species the dark spots 
are connected by a thick dark line. Near C^ape Town. 
6. Genus: TjareiitUi Tr. 
This generic name belongs ]>roperly to the Palaearctic clavaria Haw. (see Vol. 4, p. 157), but has been 
applied also to the African species which agree with Ortliolitlia except that the discocellulars of the hindwing 
are biangulate. As these are not sharply differentia,ted from a few with somewhat less elongate hindwing (for- 
inerly referred to Colostygia libn. but showing no manifest connection with the type of that genus, turbata 
Hbn.), Larenfia is here provisionally extended so as to include these latter. Antenna of the ^ pectinate. As 
thus extended, the genus has a very wide distril)iition, including a few Neotropical and Australian species and 
prevalent in New Zealand. 
L. arenaria Warr. (9f). Only known from the $ type, which is in poor condition; distinct from nicti- 
iaria in its sandy tone, the outward tooth in the middle of the postmedian and the whitish hindwing. Kikuyu 
Escar])ment. 
L. sublesta Prout. Expanse 29 mm. Pectinations rather long. Forewing sha])ed nearly as in nictitaria 
(9 g), slightly more sajidy brown, but less so than in arenaria (9 f); median area scarcely darkened, containing a 
small black cell-dot; jwstmedian line weak, much more sinuous than in the species named, the bisected band 
beyond ])ale, biit not quite white. Hindwing with termen waved, with an ap]n-eciable concavity at cellule 5; 
impure white; rather glossy, slightly tinged with lu'own distally; beneath much more irrorated with light brown 
(almost concolorous with forewing) and with a blackish cell-dot and indistinct, sinuous brown postmedian line. 
Mt. Kinangop, Al)erdare Range, 3100 m, only the type (J known. 
L. nictitaria H.-ScJi. (9g). Glossy, indistinctly marked excepting the postmedian and the whitish line 
or ill-defined band l>eyond it, but not lial)le to be confused with any other species. Hindwing l)eneath less pale, 
Avith a more definite subterminal shade. The type form, from the Cape, but extending to Nyasa and Gaza- 
land, is broumish. — cineraria Auriv., from Kilimandjaro, is larger, longei’-winged and greyer, with the hind- 
AA'ing above still more weakly marked. 
L. monosticta Butl. (= nigroeellata Warr.) (9g). More strongly glossy, more weakly marked, with 
a characteiistic black cell-mark on forewing; hindAving beneath someAA'hat streaked longitudinally, a little 
recalling Osteodes. C-ommon in the mountains of Kenya Colony and extending to Abyssinia, Uganda and 
Kilimandjaro. 
L. atrosigillata Walk. (9g). Eorewing broAvner, with cell-spot larger, lines AA'ell expressed. HindAAung 
beneath not longitudinally shaded. Namaqualand (type) to Natal and the Cape. 
L. megalaria Guen. (— atroclarata Walk.) (9g). Rather variable, but ahAnys distinguishable from 
atrosigillata by the more sinuous ])ostmedian line, Avhich, moreover, is little further from the antemedian at 
costa than at hindmargin. On the Avhole more strongly marked, the subordinate lines better developed. “Caf- 
fraria” (Cuenee). Widely distributed from Uganda and Kenya to Angola and the C-ape. 
L. dulcis Butl. (9g), from Madagascar, is smaller, the markings of the foreAAung more band-like, the 
hindwing more ochreous. 
L. diplocampa Prout (9g) is broader-AA'inged, the forewing Avith pattern of close lines and scarcely 
looks like a Ixirentia. Underside AAnakly marked, the forewing AA’ith a slight sulderminal shade, best developed 
anteriorly. unknoAvn. Cape ('olony. 
L. bitrita Feld. (10 a). Conspicuously distinct in the strongly differentiated bands (subbasal and me¬ 
dian) of the foreAA'ing. (J ])ectinations very short. Ca])e Colony (loc. typ.). Natal and TransAuial, but neA^er common. 
L. alluaudi Prout. Expanse 38 mm. Antennal ]Aectinations long, rather slender, Avnll separated. Fore- 
Aving rather glossy, broAvn; basal ])atch rather small, its edge curved; median band rather bi’oad, bounded by 
Avhitish lines and traversed by 3 irregular daik lines (1 ]U'oximal, 2 distal to the small cell-dot); proximal edge 
of the band strongly indented tAA’ice, distal edge Avith slight sxibcostal projection and moderate doul)le lobe in 
middle; a dark-shaded distal band, Avith the sid)teiininal marketl by Avhite teeth l)etAveen the veins. HindAving
