in rata- A. aerata Btlr. (= sparganii ab. strigosa Stgr.) (49 k). Eesembles sparganii in colour, but some- 



what smaller in size and with a distinct black streak along middle of forewing. Amurland and Japan. 

 algae. A. algae Esp. (= arundinis Hbn. nee F., cannae Ochs., russa Ev.) (49k). Forewing yellowish 



rufous, the rufous tint predominating in the $, the yellowish in the $; veins more or less tinged with 

 grey; a dark smudge at lower angle of cell; an outer row of dark vein-dots; hindwing grey with a 



liturata. dark paler-edged outer line; a rare form, ab. liturata ab.nov. (49 k) has both lines complete and dentate 

 throughout, the median vein thickly black; — in the Norfolk Fens a very dark form occurs, — ab. 



fumata. fumata ab. nov. (49 k), with the wings, especially in the £, dark brown or black brown. A local species, 

 found in Britain, North and Central Europe, N. Italy, Central and South Russia. Larva greenish dotted 

 with black; head brown; thoracic plate pale green; feeding within stems of Typha latifolia. 

 insoluta. A. insoluta spec. nov. (49 k). Forewing pale or dark redbrown, this ground colour, which is broadly 



visible along both folds, being elsewhere more or less covered by blackish grey scaling, speckled with 

 whitish or pale grey along the veins; outer line marked by a row of coarse black dashes on veins; median 

 vein and vein 1 more particularly whitish-scaled; orbicular stigma round and black, often obscured; reni- 

 form with the outline scarcely visible, marked by two white dots above the median vein; traces of a line 

 of dark spots in submarginal area between the veins; termen itself darker, with a row of distinct black 

 spots; hindwing dull olive fuscous, the veins towards termen shewing pale grey. 3 $$ from Oasis Ted- 

 schen, Transcaspia. Like a large coarse dissolutu. 



cervina. A. cervina spec. nov. (49 k). Forewing pale fawn colour, finely speckled with grey atoms; inner and 



outer lines marked by dark vein dots, the outer ones only distinct; a pale ochreous flesh coloured streak 

 along each fold; that in cell-fold beginning at middle of cell and reaching to subtcrminal line; that in sub- 

 median interval broad and running from base to termen; an indistinct subterminal brown shade just beyond 

 outer row of dots, externally marked by brown spots in the intervals; minute black terminal dots; fringe 

 fawn colour ; reniform stigma indistinctly paler, interrupted by the pale streak ; hindwing dull luteous whitish, 

 slightly fawn coloured in terminal third; underside greyish fawn; head, thorax, and abdomen fawn coloured,

112. Genus: Coenobia Stph. 



Tongue present; irons tufted with rough hair, concealing a projecting, triangular horny plate; palpi 

 porrect or upturned, second segment hairy and long; antennae of ^ ciliated; prothorax with crest; dorsum 

 without crests; tibiae smoothly scaled; forewings of $ narrower than those of £. Larva in base of stems 

 of Juncus lamprocarpus. Type Coenobia rufa Haw. 

 rufa. C. rufa Haw. (= despecta Tr.). Forewing uniform rufous, with an obscure dark streak from base 



along middle of wing; a row of outer dots on veins, sometimes hardly visible; hindwing pale, greyer 

 Uneola. towards termen; in the ab. lineola Stph. (48 e) the forewing is reddish grey; the veins dotted pale and 



pallescens. dark grey; the inner and outer lines shown by rows of dots; in pallescens Tuft (48 e) the red tinge is 

 wholly absent, the forewing being whitish ochreous. Common in damp swampy places overgrown with rushes; 

 often flying in the afternoon sunshine; the $$ are rarely taken, resting concealed in the lower parts of 

 the rush clumps. Occurs in Britain, Denmark, Germany, Saxony, Austria, and France. • — Larva whitish, 

 dorsally reddish; a dark lateral line, and minute dark dots on each segment; head and plates shining brown. 



stigmaiica. C. stigmatica Ev. (= lagunica Graes.) (48 e). Larger than rufa; forewing pale brownish yellow, 



without transverse lines; a black streak from base on submedian fold, diffuse below; a black longitudinal 

 streak in the lower half of cell, beginning before middle and running broader and more obscure to near 

 termen, diffuse below like the basal streak: reniform stigma represented by a long white point in this 

 streak at the base of veins 3 and 4; the terminal area is darker grey brown, the veins still darker; hind- 

 wing pale yellowish grey, with dark terminal line and pale fringe. Described originally from the Ural 

 Mts. : occurs also in the Kentei and Uliassutai Mts. ; in Amurland, and Siberia. 



113. Genus: Nonagria Tr. 



Tongue present ; frons smooth ; palpi upcurved, second segment long, thickly scaled ; antennae of $ 



ciliated; prothorax crested; abdomen slender, elongate, smooth; tibiae smooth; forewing elongate, narrow, 



the costa curved; contains only one species, which is of weak and delicate structure. Larva long and 



thin, living and hybernating in the stems of Phragmites, feeding on the leaves. Type Nonagria maritima Tausch. 



maritima. N. maritima Tausch (= sericea Curt., anella Stph.) (48 e). Forewing silky grey: the veins pale grey, 



the intervals darker, stigmata pale, hardly perceptible; outer line alone represented by a curved row of
