THYATIRA. By W. Warren. 325 



T. mdllendorffi Fixs. (49 d). It seems to me that Pixsen was premature in sinking his species to auro- mdUendorffi 

 rina Btlr. The forewing is much less strongly coloured, the pale and dark shades being less contrasted; the basal 

 patch is smaller, with less rounded outline; the pale markings in the terminal area are straighter and more 

 linear, and vein 1 is marked with white; hindwing likewise not so dark. Aurorina is a Japanese species only; 

 mdllendorffi is from Corea. 



T. aurorina Btlr. (49 e). Forewing olive tinged with purplish red in places ; a rounded pure olive blotch aurorina. 

 at base edged by a velvety black line curved from costa to submedian fold, then oblique to vein 1 and running 

 in basewards to inner margin; within the black limiting line the edge is yellow below costa, projecting yellow 

 streaks to base along costa and subcostal vein ; below subcostal white, projecting a white streak along median, 

 meeting a pearly white oblique dash from vein 1 ; in the purplish tinged central fascia are two black lines in- 

 wardly, plainest at each extremity; outer line treble, oblique inwards above subcostal in the pale costal blotch 

 above the stigmata, reappearing below vein 6 beyond cell as 3 and ultimately 5 waved lines interrupted at 

 submedian fold; followed at costa by an inwardly oblique shining yellow streak and below submedian fold by a 

 curved white black-edged line which forms externally the limit of a round olive blotch at anal angle, tinged 

 in its inner half with pui-plish; stigmata purple with pale annuli, the reniform with a pale linear centre; a purple 

 oblique shade from costa before apex containing a curved yellow streak; a pearly white curved space from 

 apex to above anal angle, followed by 4 purple blotches between veins 2 and 6; terminal lunules yellow 

 filled up with brown, preceded by a dentate dark line edged with white from vein 2 to 6; fringe brown, rayed 

 with yellow and white-tipped; hindwing olive fuscous; the fringe pink, white at tips. Japan. 



The 5 following species have longer and narrower f o r e w i n g s. 



T. apicalis Leech. Forewing pale olive grey; median area deeper, with a small pale costal patch beyond apicalis. 

 the origin of outer line; basal patch whiter, small, rounded, with dull brown clouds below median vein and 

 vein 1 ; a pale creamy white blotch at apex, inwardly bounded by the dentate submarginal line, which runs 

 obliquely and forms also tlie boundary of the anal patch, which is larger and nearly filled with brown; a row of 

 pale dark -edged terminal lunules ; fringe olive grey ; hindwing pale olive grey ; basal half limited by a darker curved 

 line, followed by paler, which again becomes darker towards termen. Near aurorina, but S7naller and more 

 delicate; described from a single J from Nitou, W. China. 



T. tenuis Hmps. Forewing fuscous; the basal area greyish, bounded by an obliquely sinuous line; an tenuis. 

 ill-defined siiuious grey line from lower angle of cell to inner margin; an irregidar grey subterminal line met 

 by an oblique dark mark from apex; orbicular and reniform stigmata small, gi^ey, edged with black;. hindwing 

 grey. Described from a $ only from Yatong, Tibet. 



T. ornata Leech (49 n). Forewing olivaceous bi'own; stigmata with black outlines; an oblong white omala. 

 streak from base of costa, thicker at base, to the dark inner line, irregularly deflexed at end and forming the 

 inner margin of that line; the upper and lower edges of the blotch diffusely dark olive; outer line blackish, 

 elbowed below costa, then nearly straight and slightly oblique to inner margin, bordered by a diffuse white space; 

 subterminal line wavy, whitish tinged with pink, expanding towards apex; a whitish pink-tinged costal space 

 above reniform stigma; a row of black pale-edged terminal lunules; fringe olive chequered with white; hind- 

 wing fuscous, with a faint cbisky median line. Allied to T. opalescens Alph., which also occurs in Western China. 



T. opalescens Alph. (49 n). Forewing pale olive brown with a slight slate coloiired tmge; a white opalescens. 

 somewhat flattened semicircular streak from base, its ends resting on the submedian fold, the upper and lower 

 edges diffusely dark olive; submarginal line broad and white, ciuwing inwards from apex to vein 6, along 

 wliich it is shortly outbent, thence oblique, parallel to termen, to vein 2, along which it is deflected mwards, 

 then again oblique to vein 1, where it is recurved to inner margin; stigmata of the ground colour ,»with darJv 

 outlines; beyoiid the reniform a whitish costal patch, before which a very obscure dark outer line rises, sloping 

 outwards to vein 6, then outcmwed to the elbow in wubniarginal line; the space within the elbow at anal 

 angle white tinged with brownish; fringe brown chequered with white; hindwing greyish white. Ta-tsien-Iu, 

 Western China. The last two species are closely allied to the Indian species undulans Hmps. 



T. pryeri Btlr. Forewing dull grey brown; an oblong whitish blotch from base above submedian fold, pryeri. 

 containing one or two black dots at base, and between the median vein and the fold tinged with bro%\aiish, 

 touching at its extremity a second oblong blotch along costa, bounded by the dark outer line; costal area 

 at base deep olive brown ; a long obli(£ue apical whitish blotch, preceded on costa by a deep olive brown blotch ; 

 subterminal line dentate, pale, preceded by a dark shade; anal blotch dull brick red; terminal lunules brick 

 red edged with black; fringe brick red, rayed with dark; hindwing fuscous; fringe rufous. Jaj^an.
