an arch, or in which they merge. — ab. umbrata Gehlen has no definite outer edge to oblique band, same merges umbrata. 
gradually fading into outer margin. — The ab. ziczac Friisch must be deemed synonymous with ab. cuspidata 
Rbl., as it only has a shade less brilliant red on hinclwings than type of cuspidata. What are we coming to 
if each minute variation in shade leads to new denominations! Also ab. mosana Lamb, is nothing else than 
a red form of ab. cuspidata Rbl. -Now follow the forms which vary chiefly in colouration: ab. grisea Gloss grisea. 
reminds one of hippophaes, as the pale ground colour of forewings is dusted with ashy grey, the patches 
of body and forewings, usually olive green, are black-green and band of the hindwings is very pale. — ab. 
perfulva Schltz. has terracotta brown ground colour of forewings without any indication of olive. — ab. perfulva. 
olivacea Gloss body and markings of forewings clay-brown instead of green; also pale patches on costal olivacea. 
margin are buff-brown, so that only a narrow band of ground colour is left (transition to ab. restricta 
R. <£■ J.). — ab. fachasii Gloss is an ab. helioscopiae, with yellow instead of red hindwings; — In ab. pallida jachani. 
Gloss all dark markings very pale, hindwings pale grey instead of red. — ab. rufomelana Tull has deep red vMida. 
ground colour to forewings, which are densely bestrewn with black scales. — A very remarkable form ab. " 
sulphurata Bdm. has ground colour on upperside (also of hindwings) like the Lasciocampid, Gh. potatoria L.. sulphumta. 
without a trace of red; underside sulphur yellow with heavy markings as the upperside. — ab. griseonytnpha griseo- 
Bdm. Forewings as grisea Gloss, hindwings as ab. lafiiolei with very narrow black band. — In ab. decolorata ^ npmplm. 
Gloss the upper side of all wings is delicate silvery grey, the parts of body and forewings that are other¬ 
wise green and black are blackish grey; thei’e is not a trace of the usual green, yellowish or rosy red 
colourations; underside similarly uniformly silvery grey without markings. — ab. albicans Gloss. Ground albicans. 
colour of forewings and distal margin of hindwings, whitish; red band of hindwings similarly very pale. — ab. 
vaiiegata Gloss, with colourations in strong contrast on upperside of forewings, the dark patches, very dark, variegata. 
the light ones, very light. Hindwings reddish white, the black band edged inwardly by a carmine red stripe. 
— ab. virescens Gehlen has an enlarged black hindwing band, similar to latefasciata but the extension is olive virescens. 
green; this green colour suppresses also the outer part of the white anal spot. — ab. oberthiiri Bdm. comb- oberthuri. 
ines the forms rubescens (on forewings) and lafitolei (on hindwings). — ab. rudolfi Bdm. has forewings of rudolfi. 
suffusa and hindwings of lafitolei. — In ab. argustaua Bdm. the central area of forewings is pale red, outer argustana. 
marginal area red-brown, green oblique band with black edge, inwardly of same a white stripe; median 
band of hindwings sandy yellow, outer margin dark red, tegulae with red edge. — ab. ilia Bdm. has a bluish ilia. 
red outer marginal area to forewings; the red band of hindwings has an orange sheen (hence the name). - 
ab. cyanea Wladasch has ground colour of forewings and also outer margin of same suffused with dark blue, cyanea. 
— The wonderfully coloured ab. incamafa Wladasch has whitish red ground colour to fore and hindwings: incarnata. 
the otherwise green oblique band of forewings and costal margin of same dark carmine red. — Similarly re¬ 
markable is ab. lilacina Wladasch. The hindwings are a lovely lilac instead of red. The type has forewings as lilacina. 
rubescens with very dark markings and a black edge to oblique band. — The ground colour of forewings 
of ab. festafa Wladasch is bluish grey, but dusted over with ochreous to rusty red, outer marginal area pale testata. 
ochreous dotted with grey-black; body and markings of forewings pale brown instead of green. The black 
submarginal band of hindwings expands as in latefasciata and is dark carmine red, the outer marginal area being 
ochreous yellow. The black abdominal patches almost merge and are edged with ochreous yellow, instead of 
white; the white lateral stripe to head and thorax is reduced and is also ochreous on the head. — In ab. roseafa roseata. 
Bdm. ground colour of forewings is carmine red, the oblique band through its entire length is lined proxim- 
ally with dull white and distally black; outer marginal area red-brown. On hindwings the white anal spot 
is suffused with rose, median band white and red mixed, outer marginal area claret. Tegulae reddish white; 
the ordinarily white abdominal marks pale red; antennae green. — ab. nigricans Gloss (= ab. nigerrima Sdlzl) 
suffused with blackish grey; the ordinarily olive green markings black-green; the otherwise red hindwings 
grey with a faint rosy red hue in centre. Underside also suffused with grey. — ab. nigra Gehlen (nom. nov¬ 
um pro nigerrima Gehlen , nee. Sdlzl) is a fine form. The black colouration in comparison with nigresccns 
and nigricans is so much increased that every trace of red has disappeared. On upperside all white patches 
remain white, so that these contrast vividly with the black colouration. Also the body is so black, that 
the black abdominal markings can scarcely be discerned. Hie usually green markings of forewings are black, 
the pale ground colour of forewings is suffused with smokey brown and is only paler at the stigma, in front 
of the oblique band and at hind margin. Underside dark brown with a few paler patches; oblique band of 
forewings and black band of hindwings more intensively dark. Edges of sternite white. — ab. conspicuata eonspicuaia. 
Bdm. has no trace of red. The central area and margin of forewings, band of hindwings and entire underside 
of all wings like white enamel. Markings much clearer and body paler than type form. — ab. flavidior Sohn- flavidior. 
Rethel is an ab. grentzenbergi with yellow hindwings, therefore a parallel form to lafitolei, but all usually olive 
green markings of hindwing and body deep golden yellow. The ordinarily white patches also yellow.-- Now 
follow the forms that vary both in markings and colouration: ab. krancheri Bdm. varies chiefly on underside: krancheri. 
ground colour dark reddish, fore and hindwings with black discal bands; those of hindwings with pale veins; 
basal area of hindwings rose in front, whitish behind, costal margin green; besides the discal band hindwings 
have a further distinct black submarginal band. On upperside oblique band of forewings edged ontwardly 
nigricans.
