PETILAMPA; DYSMILICHIA; PROXENUS. By W. Warren. 215 



74. Genus: Petilampa Auriv. 



Tongue small, aborted; palpi porrect, the second segment hairy below, the third smooth and 

 slender: irons smooth; antennae of <J shortly ciliated; thorax and abdomen without crests; the <$ of 

 slender build with ample wings: the $ stouter with the wings much smaller. Larva, as far as known, 

 in the lower parts of stems of grasses, hybernating small and feeding up in spring. Type Petilampa 

 minima Haw. 



P. minima Haw. (= arcuosa Han-., duponchehi Bsd., airae Frr. (45 h). Forewing pale ochreous, minima. 

 slightly dusted with darker, and washed with pale ochraceous; the median area in $ usually a little 

 deeper-coloured, especially in lower half; inner and outer lines fine, obscure, conversely lunulate-dentate, 

 the teeth produced along the veins, sometimes paler-edged, generally marked only by vein-dashes; sub- 

 terminal line faint, preceded by a diffuse dark shade, forming a patch at costa; hindwing ochreous, suf- 

 fused with grey, thickly towards termen, with traces of a dark outer line; some specimens are more 

 strongly suffused with ochraceous or rufous; these constitute the aberration lutescens Haw. (45 h). The lutescens. 

 species, as far as is known, has only a restricted range, being found only in Britain, Denmark, France, 

 Germany, Austria, and Switzerland. Larva ochreous, sometimes pinkish, with darker transverse bars 

 at the segments; dorsal and subdorsal lines paler; head brown; thoracic plate paler brown; feeds in the 

 base of the stems of Aira caespitosa. 



P. palustris Hbn. (= lutea Frr., luteola Fir., exilis Ev.) (45 h). ^ Forewing dull grey brown, some- palustris. 



what sparsely scaled; inner and outer lines slightly darker, indistinct; orbicular stigma an elongate dark 



point; reniforrn a narrow dark lunule; submarginal line faint, preceded by a dark shade, stronger at 



costa; hindwing paler fuscous; the smaller $ has the wings much darker, brownish fuscous, — the form 



aboleta Guen., from Norway and Lapland, is decidedly paler, the forewing more ochreous with less distinct abolela. 



markings; the hindwing whiter: — melanochroa Star, from Amurland is much darker fuscous in both me } an - 



oclivoci 

 sexes: — sajana Hmps. is a greyer form. Occurs throughout Europe except in the extreme south; also sa jana. 



in Armenia, Mongolia, E. Siberia, Amurland, and Kamschatka. Larva brownish; dorsal line whitish; head 



black: said to feed on Plantago, but more probably like minima in stems of a grass. 



75. Genus: Dysmilichia Speiser. 



Tongue well-developed; palpi short, obliquely porrect, the second segment hairy; frons with trun- 

 cate conical prominence with raised rim and a corneous plate below it; antennae of $ typically ciliated; 

 thorax and abdomen without crests; Type Dysmilichia gemella Leech. 



Sect. II. Antennae of <§ ciliated. 



D. gemella Leech (45 h). Forewing rufous brown on a yellow ground; subbasal line indicated by gemella. 

 three obliquely placed yellow dots; inner line accompanied by a yellow striga from costa and four obliquely 

 placed white spots to inner margin; outer line outcurved above and incurved below middle, traversing 

 a double series of elongated white spots with dark edges; submarginal line dark, accompanied by a 

 whitish striga from costa and another from inner margin; orbicular stigma pure white, round, with black 

 ring; reniforrn white irrorated with brown and with a brown central line, outlined with black; hindwing 

 yellowish white w-ashed with brown; the terminal area darker, especially towards apex. From E. Siberia, 

 Japan, and Corea. 



Sect. III. Antennae of <J simply lamellate. 



D. bicyclica Stgr. Forewing dull brown sprinkled with white scales, most thickly at base and along bicyclica. 

 costa; inner and outer lines thick, dark brown, conversely edged with whitish; the inner vertically waved; 

 the outer oblique outwards to vein 6, then dentate-lunulate and incurved below middle; orbicular and 

 reniforrn stigmata brown wdth w r hite annuli, the former round, the latter 8-shaped; submarginal line 

 waved, indistinct, except at costa and inner margin, where its course is marked by white scales; hindwing 

 pale brown. Only from Hi and Kuldja, E. Turkestan. 



76. Genus: Proxenus H.-Sch. 



Tongue present; frons smooth; palpi obliquely porrect, the second segment moderately scaled, 

 the third short; antennae of <$ ciliated; thorax and abdomen both without crests; mid and hind tibiae
