below middle, dentate lunulate, sometimes reduced to points on veins only; subterminal line pale, very 

 faint: terminal line black; a d?rk cell dot; bindwing largely suffused with brown red; the outer line 

 followed by a sinuous pale yellow band; cellspot dark. Satsuma and Yokohama, Japan; Ussuri, E. Siberia. 



2. Genus: Penisa gen. nov. 

 Differs from Micraeschus in having the termen of both wings evenly curved. Lam. feeds on minute 

 lichens, under fragments of which, attached to its body in the form of tufts., it conceals itself, pupating 

 in a lichen -covered round cocoon suspended by a thread of silk. Tj^pe Penisa oblataria Walk, 

 albolinearia. P. albolinearia Leech (51b). Forewing brownish grey, with slight pale and dark irroration ; inner and 



outer line u marked by black scales, conversely edged with a diffuse white band; subterminal line faint, whitish; 

 a terminal row- of black lunules; a diffuse blackish cellspot; hindwing paler. Moupin, Chang- Yang, W. China. 

 leucostida. P. leucosticta Hmps. (51 n). Forewing pale rufous with slight pale irroration; inner and outer lines 



marked by white costal spots and spots on inner margin, the outer only marked across wing: hindwing 

 with the outer line similar. Yokohama, Japan. 



3. Genus: Polyorycta gen. nov. 

 A development of Porphymvia from which it is separated by the forewing of the J 1 having 4 long 

 grooves beyond the cell between costa and vein 5; the palpi straight, obliquely porrect, and well-developed. 

 Type P. dimidialis F. 

 dimidialis. P. dimidialis F. (= secta Guen., hemirhoda Walk., roseifascia Walk., haemorrboida Moore, adulans 



Feld., basilissa Meyr.) (51 b). Forewing with the basal area yellow, limited by an oblique white line 

 minutely angled close below costa at 2 ls ; outer lire pale, straight or faintly curved and towards costa 

 inherit and crenulate to the angle cf median line, the included space bright deep rosy, wider on inner 

 margin; space between outer and. submarginal lines, except at costa, olive brown, beyond submarginal 

 again rosy; fringe rosy tipped with white; hindwing luteous whitish, suffused with ruddy grey along 

 inner and outer margins. This tropical species, occurring in India and through the islands to NeAv Guinea 

 and Australia, is also found in Japan and China. 



4. Genus: lieptosia Guen. 

 Tongue present; irons smoothly rounded; palpi upturned, stout, thickly and closely scaled, the second 

 segment long, L ,he third distinct; antennae of $ finely but distinctly ciliated; thorax and abdomen smooth, 

 without crests; wings finely sealed, crossed by parallel waved lines, rising from oblique costal spots: 

 hindwing with the markings effaced along costal area and on submedian fold. Larva oE '.be only species 

 known feeding on seeds in autumn and pupating in % slight cocoon on the ground. Type L. velox Hbn. 

 velox. L. velox Hbn. (= caliginata Tr. ; mendaculalis Tr., anomala Bmb.) (51b). Forewing bone colour, 



slightly tinged with yellowish trey; costa marked with 4 small concise black triangular spots, from 

 which *he subbosul, inner, median, and outer lines rise and cross the wing, wavy, parallel, dark, more 

 or less interrupted; submarginal pale, dentate, with grey shading on each side, that on the inner side 

 tinged with rufous; orbicular stigma a dark dot; reniform large, indistinct, traversed by the median line; 

 hindwing with only the submerginal line and its shades marked, and same wavy grey bands along the 

 abdominal margin. Mainly a mediterranean species, occurring in the South of Spain and France, in Italy, 

 Istria, the Bflkan peninsula, Morocco, Cyprus, Bitlrvnia, Lj'dia, Taurus, Syria, and Armenia. 

 velocior. L. velocior Stgr. (51 b). Considerably larger than velox, more uniformly suffused with grey; the costal 



spots brown, like the lines, not black, the lines better marked and more continuous; hindwing with the trans- 

 verse shading more developed. Eecorded only from Sicily in Europe, and from Syria and Taurus in Asia Minor. 

 dardouini. L. dardouini Bsd. (= mendacula Frr., velox Tr. nee Hbn.) (51 b). The same size as velox, but 



dark slaty grey with the lines and shadings blackish grey or brownish grey, placed as in that species but 

 thicker and clearer, edged outwardly with paler, the median line strongly bent outwards beyond the 

 reniform, the praesubmarginal shade broad; the submarginal line sinuous not dentate; the hindwing equally 

 dark, with the markings complete except in costal region. Larva dull yellow or green, with a broad 

 rod brown transverse spot on the dorsum of each segment, cut by a yellow dorsal line, and containing 

 on each side several yellow dots; head and thoracic plate dark brown; feeds on seed capsules of Antkeri- 

 cum ramosam in autumn, pupating in a slight ooccon among rubbish. Found in Portugvl, S. France, 

 Piedmont, Italy, Austria, Hungary, Bosnia: also in Bitbynia and S. Taurus. 

 miasma. L. miasma Hmps. (52a). Forewing purplish grey with fuscous suffusion: inner line somewhat 



diffuse, waved, preceded by a dark shade; outer line double filled in with whitish, outcurved above and 

 incurved below middle; subterminal grey between two dark shades; median line distinct, excurved round 

 cell, then oblique; a dark spot in cell below a dark costal spot; two blackish discoidal bars connected at 

 middle; hind wing grey suffused with fuscous, with the commencement of dark lines marked on inner margin. An 

 example is recorded by Hampson from Kiukiang, Central China; beyond this it is only known from S. India.
