de Alfacar, is thickly striated with olive grey and entirely without lines or shading, the pale olive reniform 

 stigma being quite obscure. Known only from Andalusia. 



0. lubrica Frr. (68 f). Forewing whitish grey regularly striated with darker grey; the inner, median, tubrica. 

 and outer lines rarely distinct, except at costa: when visible, cloudy and interrupted; the reniform stigma 

 brown, its inner edge velvety black, and with three black spots on its outer; subtcrminal line pale grey, flexuous, 

 preceded by a diffuse dark grey shade, the terminal area generally darker grey; hindwing dull yellowish brown 

 suffused with grey, with a broad blackish terminal border and whitish fringe; in the form obscurata Spul. obscurata. 

 (68 f) the forewing also is invaded by the yellow brown tinge, and the markings are often diffusely darker; 

 — in sublubrica Stgr. (68 f) the striae and markings of the forewing are all strongly blackish fuscous and the sublubrica. 

 hindwing is much darkened; — lubrosa Stgr. is paler ash grey, the hindwing yellower, with sharply defined lubrosa. 

 black terminal border. The species is found in the Ural and Altai Mts., Russia; sublubrica occurs in the Ural, 

 Uliassutai, and Thian-shan Mts., and in the Issyk-Kul district; lubrosa at Hi and Issyk-Kul. 



0. pastinum Tr. ( = lusoria Hbv. nee L.) (68 f). Forewing pale luteous grey covered with dark vermi- pastinwn. 

 culations; the costa and terminal area brownish grey; inner line outwardly curved, greyish brown, often obscure; 

 outer line dark edged with pale, outcurved above, indented on submedian fold, followed by a diffuse dark shade; 

 the subterminal line hardly distinct; orbicular stigma a black dot; reniform a black lunule, its lower end 

 produced outwards and followed by two black points; hindwing pale brownish grey, with an indistinct outer 

 pale line; the form astragali Bmb., from Spain, is more densely covered with dark striae on the forewing, of astragali. 

 which the terminal spots are hardly visible; on the other hand, dilutior Stgr., from the Kentei Mts., has paler, dilutior. 

 less marked, forewings; ab. decolor ab. nov. (68 f) is much paler and without any brown tinge: nearly a score decolor. 

 of this form were taken in July and August 1901 — 1903 at Tarasp in the Engadine by Mr. Rothschild and Mr. 

 Haktert; they may be identical with ab. dilutior Stgr. from Kentei. Larva pale yellowish grey, dotted with 

 black, with a row of yellow r spots in the middle and a row of small yellow spots on each side of the back; 

 laterally with a broad white grey-mottled black-dotted stripe above, and beneath an orange stripe dotted 

 with white and edged below with yellow; also a black stripe above the feet; feeds on Vicia cracca and Lathyrus 

 palustris. Occurs in Britain, Scandinavia, Finland, throughout Central Europe, Portugal, Spain, Livonia, 

 Galicia, S. Russia, Dauria, and Amurland. 



0. viciae Hbn. (— coronillae H.-Sch.) (68 g). Forewing pale lilac grey, thickly striated with olive and viciae. 

 fuscous; the costal spots (sometimes the costal stripe), the lines and shadings olive brown; the lines are often 

 very indistinct, more particularly in the $\ subterminal line paler, preceded by a broad olive shade; reni- 

 form stigma olive brown, its black edges cut up into small spots; veins towards termen finely pale; hindwing 

 pale olive grey brown, with a darker subterminal shade; in the ab. caecula Stgr. (68 g) the reniform stigma caecula. 

 is without black outline, while all the lines and shadings are clear and well defined; ab. brunnea ab. nov. brunnea. 

 (68g) resembles caecula in the brownness and clearness of the inner, median, and outer lines and of the praesub- 

 marginal shade, and in the two diffuse dark shades of hindwing, but the reniform stigma agrees with that of typical 

 viciae; the pale veins are also very little marked. The $ described has no locality label, but from the setting 

 is probably from the same locality as the $ example of caecula in the Tring Museum, viz. Wiesbaden. Larva 

 light grey; dorsal line dark, swollen on each segment, with a white central line; subdorsal lines blackish; 

 dorsal tubercles black in white rings; on the sides are dark oblique streaks, and beneath the black spiracles 

 two dark dentate lines; on Vicia. The larva of this species is said to feed up in autumn and pupate without 

 overwintering. Found in Scandinavia, the Baltic provinces of Russia, St. Petersburg, Central Europe, 

 Holland, France, Switzerland, Rumania, S. Russia, the Altai and Tarbagatai Mts., and in Amurland. 



0. craccae F. (68 f). Larger than viciae. Forewing darker grey, with a slaty violet tinge, striated craccae. 

 and dusted with darker; the veins pale; costal spots blackish; lines very faint, except the paler subterminal, 

 and that often only shown by the darker shade preceding it ; hindwing paler, sometimes with a yellowish tinge, 

 with a smoky fuscous terminal border; — ab. immaculata Stgr., like caecula Stgr., the aberration of viciae, immaculala. 

 has no black edging to the reniform stigma and the costal spots paler; — subsp. laevigata subsp. nov. (68 1), laevigata. 

 from the South Tyrol, is large, with the forewing uniformly slate coloured, and without darker dusting or 

 striation; in a 2 from Uralsk, received from M. Bartel, — ■ subsp. grisea subsp. nov. (68 g), the forewing has the grisea. 

 costal spots prominently black, the inner and outer lines dark fuscous and distinct, the space between them 

 and the terminal area both dark grey, contrasting strongly with the paler basal area and pale outward edging 

 of the outer line ; the reniform stigma has the inner edge finely black, but is filled up with the dark grey of the 

 median area, its outer edge being represented by two or three black points only ; the pale veins show up distinctly 

 in the dark grey suffusion; the hindwing is wholly dark fuscous; the example is only as large as average viciae,
