strongly oblique, of both wings faintly concave. Only known from the North-East comer of Tibet (Koko-Nor 

 and the Amdo district). 



cuprinaria. R. cuprinaria C/if. (= phoeniceariafi'mpsra.) (la) is another very distinct species, recognizable at once by 



its more rounded apex, the nearly uniform purplish-coppery hue of both wings and yellowish under-side with 

 a distal border of purplish-coppery on both wings. The lines on the forewing are placed widely apart and scarcely 

 discernible except by fine yellow luies which bound the inner line proximally and the outer distally; for the 

 rest, the position and course of the lines are most nearly as in vastaria, the inner rather strongly dentate. 

 Discal spot present on both wings, but indistinct. Occurs in S. E. Armenia, Persia, Transcaspia and Afghanistan. 

 Christoph's original figure and description are so extremely bad that it is difficult to behove that they represent 

 the same species which he afterwards figured mider the same name, and which is now called cwp-wana. Incase 

 it should prove that he confused two different species, the earlier one (perhaps of the badiaria group) must, 

 on its rediscovery, bear his name, and the present one must be called pJioenicearia Hmpsn. (erroneously de- 

 scribed as an Acidalia).

R. acidaria is apparently a locally variable species, three different races having been made kiaown 

 by Staudinger. The shape of the wings and their colour recall badiaria and terrestraria, or rather (the apex 

 of the forewing being rather acute, the distal margiia of the hindwmg well rounded) praecisaria, and there is 

 probably a really near relationship m this direction, notwithstanding the difference in neuration. The fine 

 and rather straight central luie, placed about midway between the others, will distinguish it from all the species of 

 similar size excepting vt&tcarja; from m6icana it differs abundantly in shape, in the smuous outer line and in the 

 acidaria. entire lack of rosy colouring. The under surf ace is extremely weakly marked. — In acidaria (Sif/;-. (3d) the ground- 

 colour is pale yellowish grey, the markuags moderately well expressed, the additional hne which accompanies the 

 median line distally sometimes much fainter than in the example figured. Ferghana, Thian-Shan, Issyk-Kul. — 

 grisearia. grisearia Stgr. (3 d) from further south-west (Transalai) is darker in colour and at the same time more strongly 

 alexandm- marked. — alexandraria Stgr. from south-west of Issyk-Kul, is unknown to me, but is described as bemg of a 

 )-uf. uiore reddish-yellow ground-colour and more weakly marked than acidaria acidaria, the inner line being entu'ely 

 absent, the outer only occasionally present; the under surface is much more reddish. According to Staudinger, 

 the species appears to be very common throughout central Asia. 



herbicolens-group.

herhicolens. R. herbicolcns Btlr., on which Butler founded his genus Delocharis, is closely similar to acidaria in 



colour and markings, both above and beneath, but is considerably smaller (size of vinacearia), the costal margin 

 of the hindwing relatively longer, the dark shading which follows the median line on both wings usually stronger 

 and broader, forming more or less of a band, and the distal area often more noticeably dark-shaded. North- 

 muricolor. West India. — ab. muricolor Warr., though described from Simla, will probably occur also in Palearctic 

 localities. It has the forewing of a greyish mouse-colour, the markings obliterated excepting a slight black 

 cell-spot; hindwing paler, hence retaming traces of the two transverse lines. 



tristrigalis. R. tristrigalis Btlr. (3 e) is another of the smaller species, probably related to vinacearia. The ground- 



colour is dull reddish ochreous, the markings darker. Math a more or less strong rosy tinge. The middle line, 

 as in acidaria and herbicolens, is double, usually more or less united by dark shadmg into a narrow band. This 

 character, together with the less sinuous outer line and the minute or obsolescent cell-spots will at once 

 distinguish it from vinacearia. The name of tristrigalis was not happily chosen, as it is the one species of the 

 genus which can be said to have four Imes on each wing. Under surface brighter red-ochreous, about as in 

 inconspicua, the markings nearly as above, but weaker, the mner Ime of both wmgs wanting. Dharmsala and 

 Sultanpur. 



rara. R. rara Btlr. (3 e) differs from tristrigalis and vinacearia in its brighter ochreous ground-colour (our 



figure of vinacearia ab. stigniatiui is too yellow), absence of inner liiae, at least on the hmd^ving, and more denti-
