hinules (rarely all) dark-filled proximally. Hindwino; whitish. weakly inarked excepting the cell-dot. S. Tibet: 



Nam La, Tsangpo Valley. 14 000 feet, 24 July l!t24 (J. Kingdon Ward), 7 ^,^ in the liiitish Mviseuin. Probably 



nearest the tianschanica (Alph.) grou]i (V'ol. 4. p. 224). — phariensis .sxhsp. nov. (25 e). Slightly narrower-vvinged, jiJuiriensi.s. 



Costa relatively more elongate; 1 or 2 niore joints of the anteiuia pectinate. Forewiiig with median area slightly 



broader, scarcely difi'erentiated froiu the rest except by the veiy iiighly developed white and dark vcin-dots 



(or Short dashes) f)f the adjoining areas. Tibet: Phari. IG 000 feet, I!) July 1924 (.Major Fv. W. (i. Hixg.ston, 



Everest expedition). Aspect very different. more recaUing some Coenoicphria iHdijimta or even light Colostygia 



mnUistrigaria (Vol. 4); I should iinhesitatingly regard it as a good sijecies but that a ,^ from the same expedition. 



21 July at 14 000 feet (antennae broken) has tiie shape oi oligepeles. the median area slightly more band-like 



than in phariensis type. 



X. aemyla Pront (,Suppl.-Vül. 4. pl. isf) is another high-altitude Tibetan Xanthorhoe (Poshö, E. Tibet, («•mt/la. 

 10 000 feet). Hindwäng somewhat elongate near costa (approaching the shape of an Ortholifha) and with the 

 2nd median arising from the middle of the discocelhdars, thus a2:)preciably behind the cell-fold; nniformly 

 w'hitish, with interrupted dark terminal line. Forewing, on the other band, relatively short and broad, the 

 scaling, the pattern of definite lines and the browner shades totally unlike those oi oligepeles; postmedian approxi- 

 mately parallel witli termen, its sinuosities weak. the median band brownest at its proximal and especially at 

 its distal border. 



X, moiata Feld. (25 e ,^. $). By far the commonest of a small group of S. fndian species whose differ- vwlata. 

 entiation may perhaps give some troidjle. ()n the whole smaller than the rest. Discocellulars normal for Xan- 

 fhorhoe: ,^ pectinations rather long, but not extraordinarily. Attention may be called to the sharply white apex 

 of the forewing beneath and the dark subterminaj shades of both wings. above and beneath. Forewing extreiuel\- 

 variable, particularly as regards the median liand: this ean be dark or mottlcd and nuiy enclose a very ample 

 or a narrow or incomplete pale-grey or wiiite area. often limited to an encirclement of the cell-dot (the name- 

 typical form). Hindwing above very weakly marked, jiale in the ,,^. dark in the $. Underside with the strongly 

 darkened siditerminal shade of the forewing nearly reaching tiie termen. which it touches behind the white 

 apical spot. Ceylon (type) and S. India. — ab. coarctata aor.. parallel to some Palaearctic aberrations thus ronrrtala. 

 named. has the median band extremely narrowed. strongly darkened, basal patch normal, the rest of the markings 

 somewhat blurred. Hindwing with Suggestion of a still narrower band. Nilgiris. 1 $. 



X. trusa sp. n. (25 f). Expanse 33 — 35 mm, about as in the largest moiata. Pectinations extremely long tmsa. 

 (8 or 10 times the diameter of the shaft). the difference from tho.se of moiata readily observable even with the 

 naked eye. No other infallible distinctions can yet be demonstrated, but the following indications should be 

 found useful. Forewing with the antemedian somewhat more curved (yet not nearly so much beut as in the 

 rest of the group); the area just outside the median band decidedly tinged with brown (in moiata nearly always 

 white); fringe less strongly chequered. The hindwing above and both wings beneath are a little less white than 

 in most moiata. but extremely similar thereto. Palni Hills (W. H. Campbell), the exact Situation not given 

 (from Kodaikanal, at 7000 feet. I have seen only moiata itself). The type o. in tiie British Museum, is a beautiful 

 form, with the central band of the median area broadly white, the rest of the wing predominantly dark; of 

 2 ^(^ in my collection (both with the antemedian slightly more curved). the one here figured has the white of 

 the median area less pure than in the type, interrupted behind the middle, the other has the pale central parts 

 of the area further reduced and grey. not white, therefore not very conspicuous. Some $$. probably collected 

 with tliese (W. H. Campbell), are much darkcr and cannot yet be distinguished from some moiata. 



X. greeni sp. n. (25 f). Size oi' trusa, perhaps relatively a little longer-wingcd. Antenna of the c? with r/reeni. 

 the pectinations decidedly long, though not equalling those of trusa; usually v\ith rather more joints pectinated 

 (about 37, against about 32), but curiously inconstant. Tone more brownish, especially of the hindwing, which 

 usually sliows ou the upperside 3 lines, besides indications of the subterminal shading. On the forewing the 

 Chief distinction is in the angulated antemedian, but the subbasal is also slightly more angular than in the two 

 preceding and the interrupted subterminal develops at least a clean white dot in cellule 3. Underside more dark- 

 shaded than in moiata. the subterminal bands nuicli less conspicuous. apical sjjot of forewing less «hite. some- 

 times wanting, the hindwing chai-acterizc<l by the well-developed lines of the proximal part. Discocellulars 

 of the (J hindwing not biangulate. but occasionally showing a very slight fendency to approach that form (2nd 

 radial arising just behind end of cell-fold). Founded on 5 very good si)ecimens (4 ^^J, 1 $) in the British Museum, 

 from Xamunkuli, Ceylon, February ütlO (E. K. (iREEN); also 2 Jj from .Maskeliya, February and July (C. C. 

 Alston) and a $ from Patipola. March. One aberratio)! has the band of tiic forewing more uniformly darkened; 

 in another it contains a pale patch round tlic ccll-s])ot. 



X. magnificata Walk. (25 f). Larger (30 to 42 mm), less brown than greeni, notably on the underside, »uignificata. 

 which is more mixcd with whitisli and has a fairly broad subterminal bantl, though less dark than those of
