L. coassata Bhn. (= duplicata Hhn. tig. 491 in err. = coassaria Bsd. ^= stepparia Bsd. = multiplieata coassata. 

 Stgr.) (6 e, as duplicata) is easily distinguished from all the preceding species of Lithontege by the larger amount 

 of markings on the forewing above. In addition to a dark oblique line from the apex to the posterior margin, 

 placed nearly as in griseata, Uvo further lines are present, the first antemedian, bent in the cell, the second 

 just beyond the middle, somewhat sinuous; a lunulate-dentate white subterminal line and a straighter, less 

 distinct white proximal line accompany the outer oblique line. — ab. asinata Fri\ is a more weakly marked asinata. 

 form, usually of smaller size. The dark lines are more or less obsolescent, but the white subterminal remains 

 distinct. — ochraceata Stgr., from Amurland, is smaller than the type and strongly shaded with pale oclireous. — ochraceata. 

 The type form ranges from S. Russia to the Hi district, but is local. Of its early stages we have no information. 



L. pallescens Stgr. is unknown to me. It is said to be nearest duplicata ochraceata, like that narrow- pallescens. 

 winged, but rather smaller, much lighter, dirty white with the costal margin and the veins slightly darkened. 

 Forewing with only an extremely weak, narrow, dull brownish submarginal band from the apex, weakest in 

 its posterior half. Hindwing unmarked. Under surface clearer white, the band wanting. Taken on sandy 

 ground, Tumartin-Gol, Uliassutai district. 



L. castiliaria Stgr. (^ duroata Th.-Mieg) (6e). Quite distinct from all the other species. Forewing castiltaria. 

 brown with a curved pale yellowish submarginal band. Hindwing whitish grey. Under surface much paler, 

 quite weakly marked. Only known from Castile. 



L witzenmanni Stndf. (\2a). Forewing whitish, shaded with brown, especially in the distal area; a small luitxen- 

 but distinct black discal dot and numerous dark transverse lines; proximally to the discal dot these run very »««'"«'• 

 obliquely from both margins and are very acutely angled in the cell; distally to the dot a group of 3 contiguous 

 grey lines and then a group of 3 brown ones run nearly parallel with the distal margin ; a white subterminal 

 line, not crenulate, interrupted anteriorly by an oblique dark line from apex; a further dark line exactly 

 parallel with the distal margin and a fine dark terminal are separated by a second (narrow) white line; fringe 

 white or whitish, with a fine dark intersecting line and some dark marks at tips. Hindwing dirty brovraish 

 white, browner in distal part, with very faint indications of darker lines Forewing beneath somewhat infuscated 

 the markings in part showing through from above. Described from some cfcf' from Mardin, Mesopotamia. 

 The only specimen before me, a ? from Urumiah, N. W. Persia, is rather larger and whiter, possibly 

 representing a local race. 



L. bosporaria H.-Sch. (12 a) is only known to me from the figure, which, however, is according to Standfuss bosporaria. 

 very correct. It differs from ivitzemnanni in having the brown markings developed into definite bands; a basal 

 patch and first band acutely angled in the cell; middle band parallel with distal margin, but sending out a 

 branch proximad at costal margin, thus irregularly Y-shaped; third and fourth bands parallel with distal margin, 

 the fourth close to it, not quite reaching the apex (which remains white), crenulate on its proximal edge. 

 Hindwing pale brownish grey with two white bands, 'the distal one narrower than the median. A rather 

 small (circ. 28 mm) species, somewhat recalling the South African Conchglia, the ground-colour of the forewing 

 being snow-white. Herrich-Schaffer gave the locality as "the neighbourhood of Constantinople", but Guenee 

 received it from "South Russia" and according to Staudinger it only occurs in Russian Transcaucasia. 



L, usgentaria Chr. (lib) has never been described, but is founded on a recognizable figure in Romanoff's usgentaria. 

 "Memoires". The type form, from Transcaspia, measures about 28 mm. Wings rather narrow; forewing very 

 pale grey, proximahy with a more brownish tone, distally more bluish; an obUque, slightly curved brown line 

 runs from the posterior margin near the base about as far as to the middle of the cell; a narrow brown 

 band parallel to and rather near the distal margin, edged with white proximally; a whitish subterminal line. 

 Hindwing whitish brown-grey, with one or two whiter lines or bands. The only specimen before me is rather 

 larger and more strongly marked than Christoph's figure, a distinct, though minute black discal dot is present 

 on each wing and the inner line of forewing is acutely angled in the cell and continued (though exceedingly 

 fine) to the costal margin, much as in witzenmanni. — ignorata Stgr. is nearly twice as large as the type, ignorata. 

 much darker, the forewing more distinctly and darkly marked, the hindwing fuscous grey. Ferghana. 



L amoenata CAr. (12 a). 85 mm. Forewing bluish white-grey with two bands composed of several parallel amoenaia. 

 black lines with the interspaces partly brown, partly white; the proximal band, commencing with 3 dark dots 

 on the costa, is subobsolete in its anterior part, but reappears after an acute angle in the cell and is thence 

 distinct to the posterior margin; distal band subsinuate, composed of 4 lines, about parallel with the termen; 

 discal dot small but distinct; subterminal fine thick, anteriorly irregularly dentate, but for the most part of its
