162 MANIA. By W. Warren. 



area with inner edge straight to vein 5 from anal angle, then obliquely truncate; median vein and veins 

 towards termen finely whitish; a patch of whitish scales on submedian fold beyond outer line; hindwing 

 deep olive fuscous. Che-tou, W. China. 



grisea. 0. grisea Leech (38 h). Forewing pale lilac grey clouded with darker, somewhat violet, grey, and 



dappled with dark grey; subbasal line developed into a velvety black oblique band, interrupted into 

 blotches by the veins, the ground colour immediately beyond it whiter grey; inner .line very indistinct, 

 regularly curved, not angled, as in the other species, ending on inner margin in an oblique black streak 

 nearly touching subbasal line; median shade curved parallel to inner line and like it only plain on costa 

 and at inner margin; the places of the stigmata are occupied by mere indefinite pale patches; terminal 

 area olive grey with pale veins, limited inwardly by the violet grey ground colour, the edge of which curves 

 from 2 ji of costa to anal angle; above and below vein 5 are patches of black scales within the terminal 

 dark area; hindwing dull olive fuscous; the species is still smaller than canimaculata, and is distinguished 

 at once by the absence of distinct lines; — in the ab. plenifasciata ab. nov. (39 b) the space between 

 inner and outer lines is olive fuscous, with diffuse, ill-defined outer edge. Omei-shan, W. China. 



7. Genus: Mania Tr. 



Differs from Ortliogonia in the strongly crested thorax and abdomen. Larva stout, naked, with a 

 slight hump on segment 12; the head small: hybernates, feeding up in spring; pupa in an earthen cocoon. 

 Type Mania maura L. 



maura. M. maura L. (= lemur Meinecke. virgata Tutt) (39 b). Forewing dull fuscous blackish, the median 



area usually darker; the paler ground colour being really ochreous grey, thickly dusted with fuscous; 

 subbasal line double, forming two series of groups of black scales across basal area; inner and outer lines 

 double, filled in with pale, both oblique basewards below vein 1; median vein and its branches pale; sub- 

 costal space with 5 black blotches above median area; orbicular stigma large, oblique, pale with dark 

 dusting; reniform dark with pale outline, widened outwards on both sides below; submarginal line pale, 

 preceded by a dark fuscous shade, angled outwards above and below middle; apical area above vein 6 

 pale grey; hindwing dull fuscous, with a straight pale band beyond middle, followed by a broad black 



striata, subterminal border, outwardly edged by a pale submarginal line ; in the form striata Tutt (39 b) the trans- 

 verse lines as well as the median vein and veinlets are conspicuously pale. Larva pale ochreous clouded 

 with darker; dorsal and subdorsal lines whitish, irregular, with oblique pale darker-edged streaks between; 

 spiracles reddish above a j r ellow line above the feet; on the 11th. segment a yellowish white black-edged 

 transverse stripe; feeds on numerous low growing plants. The species occurs throughout Europe; also in Ar- 

 menia, Asia Minor, Palestine, and W. Turkestan. 



muscivirens. M. muscivirens Btlr. (39 b). Forewing olive fuscous; the median area and part of the terminal 



usually much darker fuscous, the intervening space and the basal area paler; the subcostal, the median 

 vein with its veinlets across the darker areas, the transverse lines, and the outlines of the upper stigmata 

 olive ochreous; inner line well-curved, below median strongly oblique to inner margin near base; outer line, 

 bracket-shaped, slightly angled outwards above vein 4, followed by dark and light dashes on the veins; 

 claviform stigma blackish, broad and short; upper stigmata with fine pale outlines; submarginal line 

 ochreous grey, indented on each fold, preceded by a dull olive fuscous shade beyond a paler clouded space 

 which follows the outer line; hindwing dark fuscous. Japan and Corea. 



This and the following three Chinese species have more elongate, narrower forewings than the 

 European maura, approaching in this respect the species of the preceding genus Ortliogonia, likewise 

 oriental. 



vmala. M. venata Hmps. (39 c). Smaller than muscivirens, the paler basal and postmedian areas suffused 



with silvery grey, which forms a pale lunulate band in postmedian area before the narrow darker cloud 

 which precedes the submarginal line; veins slenderly yellowish; median area beyond reniform black; hind- 

 wing brownish fuscous. W. China only. Distinguished from muscivirens by the inner line being more 

 lengthily outcurved below median vein before the oblique course towards base commences. 



nyclichroa. M. nyctichroa Hmps. (41 d). The same size as venata, but with a distinct yellowish brown tint 



instead of silvery grey; the median and terminal areas hardly darker than the rest; inner line angled 

 outwards on the submedian fold, then oblique inwards; outer line closely approximated to reniform stigma; 

 the veins scarcely paler ; hindwing deep fuscous. Kiukiang, Central China; W. China. This and the follow- 

 ing species have no pale streak along the inner margin of forewing.
