wismariensis Schmidt a broad black stripe runs longitudinally through the middle of wing from base to termen; wismarien- 

 — in nigrocostata Stgr. a broad black stripe runs along the costa; — nigristriata Stgr. is more like the typical grey s f s - 

 form, but with many black streaks running parallel to the veins. Found in Britain. Scandinavia, Holland, Ger- nigrislriata. 

 many. Austria. Hungary and Russia. Larva ochreous with fine dark and light longitudinal lines; bead and 

 thoracic plate brown: said to feed witb avidity on other larvae and insects which creep into the reed-hollows.

inner and outer lines represented only by rows of dark vein-dots; orbicular stigma a black longitudinal 

 streak; the reniform represented by two black points, the larger nearer base; a small pale point beyond 

 the outer black one: terminal points black: hindwing pale grey, semitransparent ; the veins and terminal 

 line dark: the fringe pale. Described by Graeser from a single <$ from Wladiwostok, Amurland. 



114. Genus: Oria Hbn. 



Tongue weak: Irons smooth, with a rough tuft of hair; palpi slender, obliquely porrect, the second 

 segment hairy, the terminal pointed: head, thorax, and pectus with woolly hairs; thorax and abdomen 

 without crests: forewing elongate, the costa somewhat shouldered at base and inflexed before apex. Larva 

 in stems of grasses, feeding from autumn to spring. Type Oria musculosa Hbn. 



Sect. I. Antennae of r? ciliated. 



0. musculosa Hbn. (= nervosa Stph., flava Frr., frumentalis Lindem., flavescens Hmps.) (48 f). musculosa. 

 Porewing whitish ochreous suffused with yellowish, the pale ground colour showing as streaks along the 

 folds and an oblique streak from apex to end of cell, where the reniform is marked by a pale blotch with 

 a grey spot at its lower end: veins towards termen grey-tinged; hindwing whitish, washed with grey, the 

 veins darker; laeta Alpih. is a small, pale, yellowish form from Central Asia. Occurs in Central and laela. 

 Southern Europe; in Morocco and the Canaries; and in Asia Minor, Armenia, Syria, and Persia; has been 

 occasionally captured on the South coast of England. Larva pale greenish, with four dark lines at even 

 distances apart, forming spots on the anal segment; head redbrown; thoracic plate yellow; spiracles black; 

 living from autumn to spring in the stems of Calamagrostis Epigeios and Eye. 



Sect. II. Antennae of <J with tuberculate fascicles of cilia. 



0. myodea Smb. (48 f). Like musculosa but distinguished by the grey longitudinal streaks in the myodea. 

 discoidal field, in the interval beyond cell, and along inner margin. Found only in Spain and Portugal. 



115. Genus: Argyrospila H. S chaff. 



Tongue present: frons smooth; palpi short, obliquely porrect, not reaching in front of face; head, thorax, 

 and pectus woolly ; antennae very minutely serrate and ciliated ; forewing elongate. Type Argyrospila succinea Esp. 



A. succinea Esp. (= maculata Ev.) (48 f). Forewing pale olive brown, sometimes grey-tinged: a succinea. 

 streak at base of cell, another on submedian fold in the place of the claviform stigma, the orbicular and 

 reniform, — the former small, oblique, the latter obliquely lunular with a dark spot at lower end, — 

 an oblique outer line from apex to inner margin, generally interrupted above and below middle, indented 

 on each fold, and the veins at termen running out through the fringe, all shining white; hindwing olive 

 grey; the fringe white; the ab. olivacea B.-Haas has the dark shades of forewing deep olive green, the olivacea. 

 hindwing entirely olive green. Ural Mts., Armenia, Tura, Hi and Issyk-kul, Turkestan. 



A. '? formosa Graes. Forewing broad; the apex produced, but blunt; the termen sinuous, gibbous formosa. 

 beyond veins 3 and 4, incurved below apex, and oblique to anal angle; hindwing also large, gibbous at 

 middle of termen. The usual cross lines absent from forewing, which is longitudinally streaked with rosy 

 red, olive brown, greenish, and black; costa and inner margin and a streak below median vein rosy, 

 becoming brownish or yellowish as they approach termen; cell at base deep black, splitting into two black 

 lines along the upper and lower margins, the cell between them olive brown; vein 1 at base and base of 

 inner margin also black-scaled; orbicular and reniform stigmata pure white, outlined with black, the space 

 between them black; the orbicular a short dash; the remform a large lunule with pointed ends, obliquely 

 placed, with the ends curved outwards, and a small black fleck in the hollow between them; on the origin 

 of veins 3 and 4 a round white point in a black ring; terminal area gay; an oblique black streak from 

 apex to reniform; veins 3, 4, 6, 7 on red streaks radiating from beyond reniform, and containing between 

 them towards termen sharp black streaks; fringe black, mottled with yellow brown beyond the veins; 

 hindwing dark grey, paler towards base, with slight cell spot; fringe mottled from apex to vein 2, thence 

 to anal angle and also on inner margin dark grey. Described by Graeser from a single $ bred from an 

 unknown larva in August at Nicolajefsk, Amurland. 



116. Genus: Sesainia Guen. 

 Tongue weak and short; frons smooth; palpi porrect, loosely rough-haired below; antennae rather 

 short; thorax and abdomen without crests; forewing narrow and elongate. Larva in the stems of cereals, 

 pupating in situ with the head downwards. Type Sesamia vuteria Stoll.
