owing to its more luteous colour, this form approaches simulatrix, but it is always easily distinguishable by 
the wide black marginal bands of underside. From Sardinia (Gennuargentu) and Corsica (Ajaccio). — bureschi 
Toul. is a very dark slate-black form with diffuse markings from the Belesiza Mountains. — osmana Wgnr. 
(Corti i. 1.) (10 c) is more yellowish, like insulicola, rather than typical lucernea, also the transverse lines are 
yellower. The underside of hindwings is especially characteristic, it has not the black adumbration of marginal 
area, but is luteous as in simulatrix. Fringes however are white as in lucernea. Taurus, Asia Minor. 
Rh. defessa Led. (Vol. 3, p. 51). This nice species has latterly been obtained in good quantities in the 
Lebanon district and we are therefore in a position to give a good illustration (lOd). 
Rh. lucipeta Schiff. (Vol. 3, p. 51, pi. 11 e). The old illustration of this fine species, which also occurs 
sporadically in central Germany, was unsatisfactory and we are giving a better picture here (10 d). — bella 
Stephan is an aberrative $ with very heavily pronounced luteous markings and extremely dark central shade 
and extinct subterminal line. From Heuscheuer (Glatzer Mountains). — obscura and — pallida Druet are 
scarcely justified denominations of darker and paler forms. 
Rh. ashworthii Dbld. (Vol. 3, p. 52, pi. 11 f). We are giving a better illustration (lOd), as the illustration 
in Main Volume was not entirely satisfactory. 
Rh. candelaram Stgr. (Vol. 3, p. 52, pi. 11 g). The old illustration is barely recognisable, w r e are giving 
a better one (10 d). — signata Stgr. (10 e) is a nice form. The illustration is of a Swiss specimen. — lactescens 
Trti. (= calcinia Sohn-Rethel, molisana DM.) (10 e) is a remarkably aberrative and fine form of almost silvery 
white ground colour, faintly bluish in basal area, a trace of yellowish in central area and with more delicate 
and dainty markings than signata and entirely without central shade. From the middle and southern Abruzzi. — 
ab. rubescens denotes specimens that occasionally occur, where the bluish grey colouration of the main form 
is suffused, especially in central area, with reddish or reddish yellow. Schawerda described and denominated 
these from Saxony, but I have similar specimens before me from around Berlin. 
Rh. erythriiia Rarnb. (Vol. 3, p. 53, pi. 11 i). The illustration of this southern french form, that has 
become exceedingly rare, is too dull and markings are not clearly enough portrayed. We are giving a better- 
picture here (10 f). The species is now also found in Italy (Central Apennines and Tivoli). In regard to 
Switzerland it is only in the Valais that it occurs. Meanwhile however it has been discovered in Dalmatia 
(Gravosa) and described as — dalmatina Wgnr. (10 f); this has a much darker and more purplish grey colour, 
similar to that of A. senna Hbn.-G. Among this series is a dark fuscous specimen: — ab. vulpecula Wgnr. - 
BoiJRsm denotes somewhat still darker specimens from Trayas, which are classified with dalmatina, as - 
corsicina Schaw. It is somewhat larger on an average than type, dark reddish brown with purplish violet suf¬ 
fusion. The transverse lines are much more distinct and faintly reddish. Forewings are silkily glossy. The 
pale reddish postmedian transverse band and light subterminal line are very striking. Hindwings grey. From 
Evisa. — arcana Schaw. (10 f) is another very pronounced form with completely black colouration and of larger 
size. From Vizzavona at 1100 m altitude. The colour is a dark grey-black with faintly violet hue, only the 
white costal spots are distinctly marked, transverse bands merely faintly indicated. Hindwings blackish, in $ 
entirely black. 
Rh. saucia Him. (Vol. 3, p. 53, pi. 11 h). Besides the forms named in the Main Volume, the following 
have been denominated: — ab decolor Rbl. very pale yellowish grey specimens with obsolete markings. From 
Croatia. — fuscobrunnea Strd. Thorax and forewings dark brown, stigmata, costal streak, subterminal area 
and apical streak grey. — ab. philippsi Caspari is probably identical with nigrocosta Tutt, like saucia, but 
with dark black-brown costal area. — tenebricorsa Schaw. appears to be a genuine race. It has dark black- 
brown ground colour, only the costal area is faintly reddish and paler. Markings are still just discernible. 
Hindwings strikingly black to the base. Also the underside is much darker than in type. Corsica (Col de Vergio, 
Monte d’Oro). 
Rh. eminens Led. Vol. 3, p. 53, pi. 11 i). As the old illustration was not particularly good, we are giving 
a better one of this fine species (10 f). 
Rh. elegans Ev. (Vol. 3, p. 53, pi. 11 i). The illustration in the Main Volume is not recognisable and we 
are giving a better one now (10 f). This nice species seems to be widely distributed; to be added to the 
localities mentioned already, is Italy, where it has been found in the Abruzzi, occurring in profusion. 
Rh. larixia Guen. (Vol. 3, p. 53, pi. 12 i, not “21 i” as stated in Index). The illustration of this rare 
species is also not satisfactory. A better picture is now given (10 g). It is also found in the Lebanon (Becharre). 
Rh. futikei Pglr. (Vol. 3, p. 53, pi. 12 i). The illustration is quite unrecognisable. This is a relatively 
small species and we are giving a good illustration here (10 g).
