latter including a submarginal band. 

 Greece ; also recorded from Germany. — 



Found in South Europe, Spain, S. W. France, N. Italy, Dalmatia, and 

 Larva said to feed on Quercus ilex, grey when fullfed, green when young. 



monochroma D. monochroma Esp. (= distans Hbn.) (32 g). Forewing dark grey, suffused with blackish fuscous, 



but without the red tinge of accipitrina, with which it agrees in markings, but the stigmata are more unicolorous, 

 suberis. and the hindwing is darker grey; the form suberis Bsd. (32 g h), is much brighter, all the paler grey areas of the 

 type form being whitish grey, especially the space between outer and submarginal lines, the stigmata, and the 

 basal area; and these white areas are more conspicuous in the <£ than the $; the black streak from base below 

 cell is much more prominent than in the darker type. Throughout S. Europe, Spain, France, Switzerland, 

 Italy, Dalmatia, Sicily, Corsica, Sardinia, Germany, Austria, and Hungary. Larva yellowish green; dorsal 

 line narrow, pale yellow; spiracular line also yellowish with dark lower edge; spiracles white in black rings; 

 on Quercus. 



roboris. D. roboris H. G. (32 h). Forewing pale greenish grey, this ground colour only remaining in the area 



beyond outer line, the orbicular stigma, and a patch beyond claviform, the rest of wing, especially the median 

 area being suffused with darker olive brown and green; lines double, blackish; claviform stigma reddish, edged 

 with black, with a black dash to outer line; reniform large varied with red and brown; marginal area slightly 

 darker, but always with a blackish green spot on submedian fold; hindwing brownish grey, with darker cellspot, 

 cerris. outer line, and submarginal band; cerris Bsd. is a rufous-grey form without any olive tinge. Generally distri- 

 buted in S. Europe and also occurring in Asia Minor. Larva reddish grey dotted with darker; dorsal line pale, 

 traversed on segments 4 to 11 by a dark arched line, with white points in the curves; lateral lines dark; a white 

 dot before each spiracle; on Quercus, especially Q. ilex. 



protea. D. protea Esp. (32 h, i). Forewing olive green mixed with light or dark grey, varied in places with 



pale brown or reddish, the latter tints appearing along the two folds, the whole wing having a mossy appearance; 

 lines blackish, indistinct; a black streak between inner and outer lines, below the claviform which is followed by 

 a rufous patch; upper stigmata slightly paler grey, tinged with green or reddish; submarginal line pale, follo- 

 wed by blackish scaling on each fold ; hindwing dull grey, with darker cellspot, outer line, and submarginal diffuse 

 variegata. band; — ■ variegata Tutt (32 i), is much brighter and gayer; the dark shades, especially in the median area, 

 being intensified, and the paler areas, — viz, the stigmata, the inner margin on each side of the median area, 

 and the space between outer and submarginal lines, — lightened; the apex also is prominently paler and the 



Corsica, terminal area more largely blackened; — Corsica Spul., from the island of that name, is a rough brownish olive 

 grisea. green form; —from Amasia comes a form, which may be called grisea nov. (32 i), in which the tints are merely 



dejecta, dark and light grey, with only the least touch of green or brown, and a second form, dejecta nov. (33 a) decidedly 

 smaller, and uniformly dark grey with the markings all more or less obscured and the hindwing darker, whereas 

 incolorata. in grisea the pale areas are conspicuous and the hindwing whitish; ab. incolorata ah. nov. (32 i), has the ground 

 colour pale or dark grey, without coloured tints except a faint rufous flush along the two folds and the course 

 of the submarginal line. Common throughout Europe and occurring also in Asia Minor and Syria. — Larva 

 greenish, dotted with dark; dorsal line pale yellow; spiracular line yellow; spiracles black; head green; on 

 Quercus. 



intermissa. D- intermissa Btlr. Like typical protea but rougher-scaled and darker, and slightly larger; the reni-

 brown in both sexes. Japan. The Japanese equivalent of protea. 



contermina. D. con term ina Graes. (33 a). Forewing grey tinged with brownish green; the median area browner,

 brown edged with black, pointed at end, followed by a pale patch; orbicular and reniform with pale brownish centres 

 and whitish rings edged with black, the former small, oval, the latter with upper end produced; subterminal

 band. Eecorded only from West Turkestan. 



concinna. D. con chin a Leech (32 h). Forewing olive yellow dusted with black, the centre of the median area 



suffused with black; a reddish flush beyond reniform and on costal area beyond middle; veins blackish; a waved 

 black streak below cell from base; inner and outer lines black, double, filled in with yellow; the inner excurved 

 and wavy; the outer excurved above and incurved below, followed by a greyish white patch in submedian in- 

 terval; subterminal line pale with slight dentate blackish marks on its inner edge, crossed on each side of vein 

 4 by slight black streaks reaching terminal lunules; claviform stigma represented by two black streaks reaching 

 outer line; orbicular and reniform yellowish, with fuscous dusting, outlined in black; fringe chequered yellow 

 and fuscous; hindwing fuscous grey, with dark cell spot, outer line, and subterminal band; marginal lunules
