ochreous; in rufa Tutt unifonn reddish brown; and in nigricans Stgr. (= fusca Tutt) (49 g) sooty-black; rufa. 

 from another point of view, the reniform stigma ma}- contain, only one, — the lower, — white spot, or ni 9pcans. 

 neither; ab. unipuncta Tutt (49 h) and ab. obsoleta Tutt (49 g) respectively; ab. paludicola Hbn. f. 624, Tbsolrta. °' 

 if the figure is not exaggerated, represents a dark reddish brown specimen, with the median and costal paludicola. 

 veins white; a small black orbicular stigma and large black reniform with a white lunule on its inner 

 edge; and all the veins white before termen; the hindwing grey, with paler base and a dark cellspot. 

 Occurs in Britain, S. Sweden, the Baltic provinces of Russia, throughout Central Europe to N. Italy 

 and Spain. Larva pinkish ochreous; the spiracular line paler; head dark brown; feeds in stems of Phragmites. 



A. resoluta Hmps. (49 h). Forewing greyish suffused with redbrown and dusted with dark fuscous; resoluta. 

 a brownish shade below median vein and between vein 4 and submedian fold; costal edge dark brown; inner 

 line obscure, oblique, brown, dentate inwards on veins, preceded in cell by a brown point; a whitish 

 streak on outer half of median vein, its extremities slightly bent upwards, with a short dark streak bet- 

 ween them; outer line blackish, oblique to vein 7, then dentate and inwardly oblique; subterminal line 

 formed by a row of small dark marks, angled at 7, then oblique; a marginal row of black dots; hindwing 

 whitish suffused with brownish. Japan. 



A. dissoluta Tr. (= neurica Hbn. ff. 659 — 661, nee 381, hessii Bsd.) (49 h). As often happens, dissoluta. 

 the insect first described by this name is a comparatively rare dark-reddish suffused form of the much 

 commoner and paler arundineta Schmidt, to which it bears much the same relation as fratema Tr. does 

 to its type form typliae Tluibg. This form, which was formerly taken in S. W. Germany, and at Whittle 

 sea and Yaxley Meres in the fen country of Britain, has been lately rediscovered in Kent; — arundineta arundineta. 

 Schmidt (= neurica Dup. nee Hbn.) (49 h) the more general form, at least in Britain, has the forewing 

 greyish ochreous dusted with fuscous, the two folds with a slight reddish tinge, separated by a black 

 streak from base below cell, which runs as a more diffuse shade sometimes to termen; veins often dark 

 gre}' or blackish; outer line represented by black vein-dashes; the upper stigmata interrupted in middle 

 by the reddish tint of the cell; their upper portions marked by black dots; the lower lobe of reniform 

 filled with black and edged with white scales, somtimes complete throughout; a series of black marginal 

 hurdles; hindwing dirty grey; the $ is paler, narrower- winged, without any red tinge, dusted with grey ' 

 instead of fuscous, without the strong black median streak; the two folds olive fawn colour; the black in 

 lower lobe of reniform strong and edged with white; the hindwing paler, showing more clearly a dark 

 outer line and terminal shade; the underside of both wings with a distinct dark cellspot. Found in 

 Britain, Holland, Denmark, Germany, S. Russia; in N. Persia and Turania. Larva dirty white, often with 

 a reddish tint, sometimes also pale green; the tubercles dark; spiracles white in black rings; head dark 

 brown; thoracic and anal plates pale brown; pupates in lower end of the reed stem. 



A. neurica Hbn. (= edelsteni Tutt) (49 h). Forewing brownish fawn colour, hardly dusted with neurica. 

 darker; no distinct dark streak along middle; edges of stigmata marked by pairs of black dots above and 

 below, interrupted in cell; the upper half of each broader than the lower; (in arundineta this is not 

 the case;) median vein marked with black and white scales; lower lobe of reniform not black, but 

 some black scales above median vein on each side of it; inner and outer lines complete, the latter strongly 

 hmulate-dentate ; a row of black marginal lunules; hindwing brownish grey, with dark outer line and 

 terminal border; tips of shoulders white; underside without cellspots or other markings. Occurs in Britain, 

 S. Sweden, Germany, Austria and Transylvania. Larva dull bluish green, with 3 faint pale grey dorsal 

 lines and fine black tubercles; spiracles black; head black-brown; thoracic plate yellowish brown with 

 darker edge and dots; living, like the previous species, in reed stems. 



A. polita Walk. (= nonagriella Walk.) (49 h). Forewing reddish or fulvous brown, densely sprinkled with polita. 

 black, the two folds clearer, without speckling; lower ends of stigmata shown by black dots ; inner and outer 

 lines marked by black vein-spots; a marginal row of black dots; hindwing paler brown. China and Japan. 



A. phragmiticola Stgr. (49 i). Forewing dark brownish grey, with a white streak and dark points ^^to. 

 on outer half of median vein and just beyond; darker than arundineta, the same colour as dissoluta; no 

 trace of reniform stigma; veins before termen whitish; hindwing dull fuscous. S. Ussuri district, Amurland. 



A. sparganii Esp. (49 i). Forewing light yellowish ochreous flushed with rufous, especially in the <J; sparganii. 

 veins paler, and sprinkled with dark fuscous, especially the median vein; lines represented by series of 

 black spots, the outer only distinct and complete; reniform stigma marked by two or more blackish dots 

 at its lower end; a series of black terminal dots; hindwing pale dull yellowish, more or less suffused with 

 fuscous, except towards inner and outer margins. Britain, S. Sweden, Central Europe, N. Italy, Russia. 

 The species is variable both in colour and clearness of markings; thus ab. obsoleta Tutt (49 i) is an obsoleta. 

 ochreous form dusted with grey and without any reddish or yellowish admixture; ab. rufescens Tutt (49 i) rufescens. 

 has the forewing more or less strongly reddish and the hindwing suffused with fuscous to outer line; 

 while ab. bipunctata Tutt (49 i) has a black dash above median vein, representing the base of an otherwise bipunclala. 

 unmarked orbicular stigma, as the black crescent with its pale centre at end of cell represents the reni- 

 form; this form is independent, of colour. Larva slender, pale yellow green; subdorsal and lateral lines 

 darker; head and thoracic plate pale brown; feeding in stems of Typha, Sparganium, and Iris.
