62 ACIDALIA. By L. B. Prout. 



the areole, but it is doubtful whether this would preve constant. Forewing usually with all 5 lines present, 



somewhat ferruginous-tijited, the first sharply angled m the cell, the second (corresponding to the principal 



line of arenosaria) somewhat the strongest and well beyond the middle, the last three (post median and two 



subterminals) near together; cell-spot present. Hindwing paler and more weakly marked, but not devoid of 



markings like arenosaria. Margin of both wings with dark dashes between the veins. Under surface of both 



albiceraria. wings very pale yellowish, with median and postmedian lines present. — albiceraria H.-Sch. (= sulphuraria 



infuscata. Frr.) is the smaller and less distinctly marked form and inhabits S. E. Russia and Transcaucasia. — ab. in- 



fuscata I will take drawing from H.-Sch. ab. nov. (= ochroleucaria H.-Sch. fig. 469, 470, nom. praeocc.) 



vitellinaria. (7 a) is a form with almost the whole of the forewing much darker, suffused with fuscous. — vitellinaria Ev. 



represents albiceraria in Persia and Siberia, extending in the latter country from the Altai to the extreme 



east (Amurland, etc.). It is larger and more sharply marked, the discal spots of both wings strongand black. 



iimnistaria. A. imtnistaria H.-Sch. (4 h) is somewhat ampler- winged than the two preceding and of a lighter sul- 



phur-yellow (our figure does not represent one of the brightest forms). It is at once distinguished from them 

 by the two fine, ivavy brown lines, darker punctuated on the veins. Discal and terminal spots black, not ex- 

 tended into dashes. Subterminal shades faintly indicated. Under surf ace with thick postmedian line, the base 

 of the forewing suffused more or less with brown. The $ antenna is furnished with moderately strong fascicles 

 of cilia, the hindtarsus at least as long as the tibia. Taurus to Transcaucasia and Persia. 



latelineata. A. latelineata Graes. (=divisariaCAj\) (7b) is another conspicuous species. Larger than arewosana, which 



it nearly resembles in the markings of the forewing. Ground-colour of forewing rather deeper and more ochreous, 

 the brown postmedian line thick and strong, the outer of the two subterminals stronger than the inner. Hind- 

 wing paler, but with the markings of the forewing reproduced. Cell-spot almost or entirely wanting on both 

 wings. Under surface similarly marked, the basal area, at least of forewing, usually with some brown suffusion. 

 The 9 is rather smaller than the 3*, and with slightly nari'ower wings, but otherwise similar. Apparently 

 local, recorded from the Southern Ural, West of Issyk-Kul and from the Hi district. A specimen before me is 

 from the Alexander Mountains. 



ieckemria. A. beckeraria Led. (7 b) Pale grejdsh ochreous with sparse grey dusting, the lines grey, little darker than the 



ground-colour, but the antemedian and postmedian marked with black spots on the veins; antemedian bent 

 in cell, wanting on hindwing ; median shade sinuous, not very thick, on forewing following, on hindwing prece- 

 ding the sharply black discal dot; postmedian lunulate-dentate, the teeth accentuated by the black vein-dots, 

 somewhat oblique outwards from costal margin of forewmg, a little incurved between the radials; dark distal 

 shading and pale subterminal line very weak; distal margin with black dots or short dashes between the veins. 

 Underside paler, weakly marked. Vertex of head also paler, collar brown, cj antennal ciliation regular, not very 

 long. The specimens which I have seen, from Sarepta in some numbers and one or two from Syria and from 

 Quetta, show comparatively little variation and Herr Pungeler writes me that the form which has recently 

 been taken in numbers in Central Italy also only differs m being of a rather more whitish tone. When Stau- 

 DiNGER (Iris, vol. 5, p. 154) speaks of it as a strongly variable species, I suspect that this is chiefly due to his 

 having confounded several species under the one name. That this is at least partly the case, has been 

 shown above, under rubellata and cumulata. The range of variation in true beckeraria is chiefly in the strength of 

 the markings, both on the upper and under surfaces; in particular the central shade, which is usually rather 

 indistinct, sometimes forms on both wings above a quite strong dark central band, the dark shading proxi- 

 mally to the pale subterminal line also being subject to some intensification. It may be that in some of the 

 Asiatic localities from which I have seen no material, more striking aberrations or local races do really occur. 

 Alpheraky records two handsome greyish, strongly marked specimens from Kuldja, where, however, most 

 of the examples are quite typical. A pair from Quetta (a hitherto unrecorded locality) collected by Nurse in 

 June 1902 and 1903 and now in the British Museum, are also normal in all respects. The species has a wide 

 area of distribution, extending locally from Italy through Southern Europe, Asia Minor and Syria to Central 

 Asia and N. W. India, and including S. E. Russia, the locality from which it was first known. Also once in Shan- 

 Si, Central China. It is said to occur in June and July, but at least in the Kuldja district there are two gene- 

 assimilaria. rations, April and August. — assimilaria Stgr., likely a distinct species, is said to differ in possessing only the 

 two lines, placed at equal distances from the central spot, the outer not sharply dentate, and in the distal 

 area a strong, complete dark band, much further from the outer line than in the allied forms; on the hind- 

 wing the central spot is placed proximally instead of distally to the inner line. Described from a single $ 

 from Ferghana. 



rebeli. A. rebel! nom. nov. (= agraria Rbl. nee Joan.) is extremely like a small, whitish form of beckeraria, 



to which, indeed, it was referred by Staudinger, but is distinguished by having the vertex snow-white and the
