LYGRIS. By L. B. Prout. 



rufescens. and hindmargin, enclosing a small pale area in the middle. — ab. rufescens Gmphg. is described as ferruginons- 

 ochreous, the median area infnscaled, not paler in the middle, the hindwing with a dentate dark line and 

 musauaria. reddish border. — ab. musauaria Frr. is much darker than the type, dark reddish brown with the margins 

 of the central area indicated in blackish, a pale (or even white) line from costa to (he 3'''' radial often remain- 

 ing conspicuous distally to the postmedian; hindwing also somewhat smoky. A frequent form in some localities 

 fuscata. (Scotland, N. England, the mountains of Silesia, Bavaria, etc.) but quite wanting in others. — ab. f uscata Prow^ 

 is a more extreme and much rarer development. Both wings uniformly blackish fuscous, the markings altogether 

 obliterated. I have only seen it from Scotland: Barrett figures one on pi. 361, fig. 3 c of his well-known 

 work. — Larva rather slender, nearly cylindrical, head and prothorax small, mesothorax slightly swollen; 

 variable in colour, grey, brown or green, more or less darkened mediodorsally and u.sually with a pattern of 

 small somewhat V-shaped dorsal markings at the ends of the first 5 abdominal segments. It feeds chiefly on. 

 Vaccinium, but also on heather and sallow. Imago in July and August. Central and Northern Europe, parts 

 of Siberia and Kamtschatka. 



perspicuata. L, perspicuata Piing. differs from populata in having the. basal and median areas and distal marginal 



patch sharply dark brown, the pi'oximal edge of the median area angled in the middle, not rounded, and the 

 o" antenna thicker, with the joints not angularly projecting. The ground-colour of the forewing is similar to 

 that of populata, the hindwing is grey-dusted and has 2 whitish lines. Underside paler than upper, the fore- 

 wing pretty uniformly darkened from base to postmedian. Koko-nor. 



peloponne- 

 siaca. 



mellinaia. 



L. peloponnesiaca lihl. Ground-colour as in mellinata, but very distinct in the dark brown colouring of 

 the basal area and median band of the forewing and in having the latter broadly interrupted before the hind- 

 margin (isolating a small dark spot between the 2"'' submedian and the margin). Palpus with 3^*^ joint distinct. 

 Antennal joints in cf with sharply projecting ends. Shape of wings similar to that of pnuuita. Basal area 

 of forewing broad, with blunt projections, bisected by a pale line and distally edged with white; median band 

 also white-edged, broadest at costa, here enclosing a small, dark-pupilled pale space; apex with dark oblique 

 line, termeji from here onwards somewhat darkened. Hindwing pale yellow-grey with a darker postmedian 

 line. Underside yellow-bfown with dark cell-dots (that of the forewing weak) and postmedian line, forewing 

 darkened distally; cf "hair-tuft yellow-brown. The larva was discovered on gooseberry and POngeler has bred 

 it from the egg. Larva in April-May, moderately slender, slightly flattened, tubercles white; colour usually 

 light green, with dark dorsal line and white subdorsal and ventral ; a rarer brown variety recalls pnmata 

 larva. Imago in June. Taygetos, Morea, at elevations of over 1000 m. 



L. mellinata F. {■= associata Bkh. = marmorata Hbn.) (8 f, as associata). Scarcely at all variable and 

 easily distinguished from populata ab. dofafa by the dilferently shaped central area; the more strongly spotted 

 fringes are also distinctive. Larva elongate, cylindrical, yellow-green with darker, more bluish green dorsal 

 line, which is finely white-edged, very fine white subdorsal and fine white lateral. On Ribes rubrum and 

 nigrum, preferring the former; it feeds at night and is extremely sluggish. Full-fed in June. Pupa bright green, 

 the markings brown. Inhabits a great part of Central Europe and Russia and the Altai and Changai Mountains. 



deslinata. L. destinata Moschl. (7e). An Arctic species and not yet known from the true Palearctic Region, 



being only recorded from Labrador. Closely related to prunata, but of a much duller, greyer tone than the 

 normal forms of that species: best distinguished by the different shape of the basal patch, which shows a single, 

 lugubrata. rather sharp angle. According to Moschler a very variable species. — ab. lugubrata Moschl. is said to be 

 darker, having both wing infuscated, with less markings and these less distinct. Moschler's type was blackish 

 with lighter median area, and with fine white lines. Possibly a local race in some parts of Labrador. 



kdcreri. L- ledereri Brem.{Sg]. Nearly related to testata, both wings with a similar glos.sy testaceous ground- 



colour, bui rather darker and with still less yellow admixture. Much larger, the antemedian white line very 

 oblique, joining the postmedian fine on the 2""* median vein; subapical patch conspicuous and as distinctly 

 expressed beneath as above; underside otherwise similar to that of testata. Ussuri district and Japan. 



roessleraria. L. roessleraria Stgr. (8 g) is suggestive of a smaller, paler edition of ledereri, but has the markings 



better defined, the basal dark part extraordinarily obliquely margined and ending in some characteristic marks 

 at the hindmargin; median costal patch narrower, with a whitish costal mark in its centre. Under surface 

 clearer and more yellowish, the type of marking more recalling populata than testata. Found in the Taurus, 

 perhaps also in the north of Asia Minor. 



converge- L. convergenata Brou. (8 d) is again very distinct in having the markings more broken up into lines, 



nata. the first 3 extremely oblique; some dark, ochreous-mixed markings at the posterior angle of both wings further 

 approximates this species to ludovicaria, but it is abundantly distinct in colour and pattern. The long palpus 

 associates it with the ledereri group. S. E. Siberia and Japan.
