but rather smaller; forewing grey with black dusting and pale cross lines; the hindwing (cf) as in capnistis, 

 white. — Zeitun, in Asia Minor.

semna. R. semna Piing. Close to capnistis Led., but paler, the markings clearer; the veins all pale grey 



and the lines pale; a row of blackish wedgeshaped marks before submarginal line; hindwing white. Askhabad. 



rectangida. R. rectangula Schiff. (= exclamans Ev.) (lOi). Forewing purplish brown with grey irroration; costa 



with dark brown triangular spots; cell between upper stigmata and the base (sometimes the whole) of 

 claviform blackish; edges of stigmata very slenderly ochreous, the reniform retracted along median vein to

andereggii. at base. — ab. andereggii Boisd. (12c) is darker, without the grey irroration, the lines not showing paler; 



acutangula. while in ab. acutangula Stgr. the forewing is browner, and the stigmata more conspicuous. In Europe this 

 species occurs in Switzerland, Italy, Austria, Roumelia and S. Russia; in Asia Minor, W. and E. Turkestan 

 and W. and E. Siberia. — Larva grey; dorsal line narrow divided by a row of yellowish spots: subdorsal 

 lines yellowish; lateral lines broadly brown, with the white black-bordered spiracles on their lower edge; 

 head yellow brown with 3 black streaks; on low plants, among which are enumerated clover and melilot. 



moerens. R. moerens Stgr. Forewing blackish, tinged with purplish-grey; the lines indistinct; claviform 



stigma large, black-edged; cell and space beyond to outer line black, defining the upper stigmata; hind- 

 wing dark fuscous, paler in cell. Described by Staudinger from a single d* from Urga, Mongolia. 



melanura. R. melanura Koll. (lOi). Forewing creamcolour; lines marked by black spots on costa and inter- 



rupted marks across wing, the outer line with a swollen spot on each fold; a broad black marginal border; 

 fringe dark, with base and tips paler; reniform stigma alone sometimes represented in outline; hindwing 

 grisescens. white, the dark border paler and more diffuse. — The form grisescens Stgr., which is smaller, is said to 

 melanurina. have the forewing dull grey; — melanurina Stgr., queried by him as gener. aestiva?, is only half as large 

 as the typical examples with forewing yellower and more slender dark border. — The only European 

 locality is Dalmatia, whence it was first described ; in Asia it occurs in Asia Minor, Persia and W. Turkestan ; 

 the form grisescens comes from Persia and Pontus ; and melanurina from S. Palestine.
