SIRINOPTERYX. By L. B. Proot. 335 



other plants, hibernating. Moth in July, a few small second-brood specimens in September. Central and S. 

 Europe to Altai. — persica Men. (= nivea Btlr.) (17 c) differs in being white or almost white, the lines often persica. 

 thicken, fringe of forewing more reddish, apex less falcate. Very variable in size. Distributed from Trans- 

 caucasia to Japan. Thibrry-Mieg and Bastelberger unite it with ebuleata. — citrinata form. nov. Shape dirinaia. 

 of persica, lines and cell-mark at least as thick, ground-colour as bright yellow as in sambucaria, shghtly more 

 greenish tinged, with stronger greyish strigulation, the Lines more greyish. W. China: Pu-tsu-fang, June — 

 July, 4 (J(J in coll. Brit. Mus. Perhaps a distinct species. The ochreous brown face distinguishes it from ebuleata. 



0. similaria Leech. (17 c). Similar to the whitest persica, forewing rather shorter, the distal margin nimihmn. 

 being less oblique, hindwing with tail shorter, the secondary tail at the 1st radial relatively better developed. 

 Face and palpus bright golden brown, face paler below. Omei-shan and Chang Yang. Also on Formosa. 



0. cretea Swinh. (= ? lata Matsumura) (17 f, as cretacea). Smaller than similaria, hindwing rather creiea. 

 narrower, tail stiU shorter, wings less strigulated, line on hindwing rather more curved. Lower part of face 

 sometimes white. Japan. Possibly a Euctenurapteryx; I have before me $$ only. 



0. ebuleata Guen. (= multistrigaria Walk., kantalaria Feld.) (17 d). Very like persica but generally ebuleata. 

 intermediate towards the colour of sambucaria. Differs from both in having the face white or whitish, except 

 a narrow band on upper part. Apex of forewing not falcate. Strigulation on forewing and distal part 

 of hindwing strong, nearly always some slight grey shading between the spots at the tail. Lines and cell-mark 

 generally thick. My material agrees with Gxjenees description; OsBRTHtiRs figure is brownish, scarcely recog- 

 nizable. N. India and W. China. — ■ yerburii Btlr., founded on a single discoloured $ from Murree, is perhaps yerbmii. 

 an aberration, differing chiefly in shape; apex of forewing sharper, distal margin faintly subconcave; tail of 

 hindwing longer, lines rather slender. Face apparently not whitish. Alpheraky records an example from 

 Szechuan. — purissima Th.-Mieg (= thibetaria Bastelb.) is white, scarcely tingend with yeUow, fringe of pvrissima. 

 forewing white. Face white, otherwise it might be confused with persica. Alexander Mountams, Central Asia; 

 ,, frontier of Tibet" at 3000m elevatoin (?). — caschmirensis Bastelb. is also white, but larger, costal margin cascJimiren- 

 broadly white, scarcely stringulated, Hnes more leaden grey. Face pure white with narrow red-brown band *''*■ 



above. Kashmir. 



0. pluristrigata Warr. (17 c) also has the ground-colour pure white, face and palpus also white, the phirisiri- 

 forewing rather evenly striated with pale fuscous, fringe not rufous, the hindwing with the spots smaU, the ^" "' 



fringe faintly tinged with rufous. N. W. Himalayas. 



0. costistrigaria Leech (17 e). Differs from all the foregoing in the black costal marks, the strong, cosUsiriga- 

 almost continuous strigulation of the distal area, etc. W. China: Omei-shan. "*• 



0. latitnarginaria Leech (17 e) is possibly a remarkable aberration of the preceding, but the lines are latimargi- 

 narrower, that of the hindwing rather differently placed, the costal strigulation slighter, distal area of fore- nana. 



wing almost entirely black-grey, the 2 normal spots of the hindwing large and red, a third spot posteriorly 

 to them black. Omei-shan. 



0. excellens Btlr. (17 e) is very distinct in the more oblique antemedian line, the dark streak along exceliens. 

 the 2nd submedian of both wings, row of black terminal spots of hindwing etc. Dharmsala. 



0. kernaria Ob. (17 d). Whitish, the usual lines thick and in addition with both wings irregularly fcemaria. 

 spotted with grey-brown. Hindwing with 3 black spots at distal margin. W. China: Tse-kou. 



0. adonidaria Ob. (25 b). More yellowish, stiU more strongly spotted, postmedian line differently adonidaria. 

 placed, hindwing with shorter tail and only two marginal spots. W. China: Tien-Tsuen. 



0. aristidaria Ob. (25 c) is according to the figure certainly no Ourapteryx, but as no structural clue arisHdaria. 

 is given it must be provisionally left here. Shape and general aspect of the African genus Eurythecodes 

 or the American Antepione. Yellow, with slight purple-brown irroration; a postmedian hne at about two- 

 thirds (on hindwing scarcely beyond one-half), distally to which both wings are entirely purple-brown. Discal 

 dots minute. Antenna in ^ perhaps bipectinate. Possibly related to Auaxa. W. China : Siao-lou. 



63. Genus: JSiriuopteryx Btlr. 



Characters oi Ourapteryx, but with the first two subcostal veins of the forewing arising separate, the 

 1st successively anastomosing with the costal and with the 2nd subcostal. Only 3 or 4 species are known, 

 chiefly N. Indian. 



S. rosinaria Ob. Bright yellow, the costal edge of forewing (more broadly at the base) and all rosinaria. 

 fringes red; cell-spots black, above mixed with red, lines weak, greyish, the antemedian sinuous from cell- 

 spot to hindmargin. Distal margin of hindwing crenulate, the tail rather slight. Siao-lou, W. China.
