178 SIDEMIA. By W. Warren. 



15. Genus: Sideniia Stgr. 



Tongue well-developed; frons smooth; palpi upturned, the second segment hairy in front, the third, 

 usually, quite short: thorax with hairy vestiture; the prothorax and metathorax slightly crested; abdomen 

 without crests: forewing with termen crenulate. Type Sidemia speciosa Brem. 



Sect. I. Antennae of $ bipectinate, the apex serrate. 



spilo- S. spilogramma Bmb. (= christophi Alpli.) (41 g). Forewing purplish fuscous, somewhat blacker in 



gramma. me ji an area ■ inner marginal fringe white with black scales protruding over it ; inner and outer lines black, 

 obscure; the median shade thick and black; claviform stigma obscure, with some ochreous and dark 

 scales; orbicular and reniform blackish, with distinct yellowish white annuli; submarginal line very slight, 

 indicated by a blacker shade preceding it; hindwing with basal 2 J3 whitish, the veins fuscous; the terminal 

 border dark fuscous, broad at costa narrowing off to anal angle; fringe whitish. Sarepta, S. Eussia; 

 Siberia ; Amur/land. 



inutilis. S. inutilis Alph. (42 a). Forewing whitish with brown irroration and suffusion; the area from end 



of cell to termen at apex and vein 2 fuscous ; the median nervure and its nervules and the submedian vein 

 white to beyond outer line; inner and outer lines double, filled in with whitish; claviform stigma narrow 

 and elongate, whitish, with fuscous lateral edges and central line; orbicular wedge-shaped, whitish with 

 fuscous outline: reniform with fuscous centre and outline, the annulus whitish; submarginal line obscure, 

 with dark marks preceding it; hindwing white, the costal and apical areas fuscous; a row of terminal dark 

 points from apex to vein 2. Corea. I doubt if this species is distinct from depravata Btlr., which varies 

 much in size. 



depravata. S. depravata Btlr. (41 g, h). Forewing pale grey suffused with dark grey and often with a brownish 



tinge; the costal area sometimes remaining paler; median vein and veinlets and the submedian paler; 

 inner and outer lines black, conversely lunulate-dentate; the inner prominently projecting on submedian 

 fold; the outer preceded by black diffuse markings between the veins, that on submedian fold enlarged; 

 submarginal line pale and waved, also preceded by black markings; a black spot in cell before orbicular 

 stigma which is often flattened and elongate; the reniform large, with dark centre and outline; sometimes 

 a black dash below median vein between basal and inner lines; hindwing whitish, gradually becoming 

 smoky fuscous to termen; varies considerably in size, the c?c? generally rather larger than the $?; typical 

 suffusa. examples are pale grey and show the markings clearly; in ab. suffusa ab. nov. (41 h) these are all more or 

 less obscured by a dull dark grey suffusion. Japan, Corea, China. 



Sect. III. Antennae of $ with sessile fascicles of long cilia; palpi with third segment longer. 



contecta. S. contecta Graes. $. Forewing ochreous white, tinged with rufous brown; inner and outer lines 



black, well-marked; the former outcurved and obsolescent towards inner margin; the latter oblique out- 

 wards to vein 6, then oblique inwards; median shade diffusely darker; orbicular stigma whitish, lunular; 

 reniform brown in centre, the annulus white and outline black; subterminal line whitish, diffusely widened, 

 with darker shading on both sides; hindwing whitish, becoming fuscous towards termen, the veins darker; 

 fringe white; in the $ the abdomen and both wings are strongly tinged with brown. Issyk-kul and 

 Alexander Mts., YV. Turkestan. 



zollikoferi. S. zollikoferi Frr. (41 h). Forewing dingy greyish ochreous, dusted with dark grey, especially in 



the $; lines hardly visible; the outer indicated by slight dark and pale dashes on veins; the submarginal 

 paler with grey edges, the terminal area faintly darker beyond it; orbicular and reniform with faint pale 

 internigrala. annuli and grey scaling; hindwing dull whitish, tinged with brownish grey along termen; — ab. internigrata 

 ab. nor. (= ab. 1. Hmps.) (41 h), shows the lines and markings clearly, being suffused with blackish between 

 the subcostal vein and submedian fold to outer line and more densely before and beyond submarginal line, 

 the veins all being of the pale ground colour; the wedgeshaped marks before submarginal line, except 

 between veins 6 and 7, black; stigmata paler and plainer; a slight trace of a dark-edged claviform; hind- 

 wing whiter, with dark fuscous terminal border and black terminal line. Larva green, feeding on low 

 growing mountain plants. A species of sporadic occurrence; Britain, N. Germany, Hungary, Switzerland, 

 Eussia, W. and E. Turkestan; the aberration only from the Ural Mts. 



slandfussi. S. standfussi Wi.sk. (41 i). Differs from zollikoferi in being smaller, fuscous-grey; the inner and outer 



lines and the upper stigmata pale; hindwing whitish, the terminal area fuscous preceded by a curved dark 

 outer line. Found in Switzerland, in the Tyrol, in S. Bavaria, Upper and Lower Austria, and in the Mts. 

 of Boumania. 



Sect. 1Y. Antennae of $ subserrate, the serrations with short tufts of cilia and a longer bristle. 



speciosa. S. speciosa Brem. (= bremeri Ersch., snelleni Stgr.) (41 h). Forewing pale lilacine grey, suffused, 



between subcostal vein and submedian, with deep olive brown, darkest on the two folds; basal area of
