Addenda: ILERDA; THESTOR; CHRYSOPHANUS. By M. Gaede. 
not so irregularly formed. The inner one is straight, the outer one slightly curved approximating posteriorly. 
Both submarginal lines extremely dentate. East Kansu. As these difference's may be due to a bad execution 
of the illustration on the part of Leech, I am not denominating the form. 
B. Group of Polyommatini. 
18. Genus: Ilerda Dbl. 
I. epicles Godt. The primary form is frequent in Java. Whilst indicus Fruhst. has a narrow red discal 
band on hindwings and the reddish subapical spots are absent on forewings of typical the subapical trans- 
chinensis . verse band of forewings is much narrower in chinensis Fruhst. from W. China and even more reduced than 
in indicus. (This description does not seem very comprehensible.) 
21. Genus: Thestor Hbn. 
cyrenaica. Th. ballus F. — cyrenaica Trti. is much smaller than specimens from S. Europe and also smaller 
than those from Algeria. The dark ground colour of the <§ corresponds to the latter race. Marginal streaks 
on hindwings are small but distinct, they are larger and more diffuse in european specimens. The dark 
margin on forewings of $ are said to be narrower and ground colour with brighter golden gloss. On hind¬ 
wings the golden red marginal band is generally much narrower and more sharply outlined. Cyrenaica. — 
illuminata. illuininata Trti. is the name given to a single $ having a row of fuscous spots on fore wings beyond the 
cell, similar but smaller than in nogelii. On hindwings the yellow-red marginal spots are large, somewhat 
like in Lyc. astrarche. — In Ronda (Spain) the species varies from typical coastal form already at an alti- 
phychro- tude of 800 m: phychrokoilios Forbes, it is smaller and jialer in colouration. In the 3 the orange-yellow 
koihos. c | us ting is absent on underside of the dull grey forewing. Underside of hindwing is blue or greenish blue 
instead of yellow-green. 
22. Genus: Clirysopliaiiiis L. 
bergeri. Ch. virgaurea L. — bergeri Schindler is an aberrative specimen with pale golden upperside forming 
deUcata. a transition to the whitish yellow pallida Rbl. — delicata Higgins is a small race from the Col de Sestrieres 
(Cottian Alps). Ground colour of upperside of $ somewhat pale and black margin narrow, especially on hind¬ 
wings. Marginal spots of the latter occasionally very small, discal spot being absent on forewings. Underside 
of hindwings and margin of forewings pale, often almost yellow. Spots of forewings distinct, sometimes large. 
White band on hindwings very reduced. As Verity considered these specimens to be zermattensis one can 
assume that inspite of the full description, the variations are minute. 
gabori. Ch. dispar Haw. — The subspecies gabori Diosz. has a black spot in cell on upperside of forewdngs 
bimacula - and heavier marginal lunules. — ab. bimaculatus Diosz. actually has 2 black spots in cell of forewing and 
ius - margin of hindwings is somewhat yellowish. Evespots of underside are larger. — minor Diosz. is naturally 
smaller. As is found among all races, specimens are found among batavus having the hindwings black except 
posticea- for the typical submarginal band and these are named posticeoatrata Metzger. Specimens without this band 
atrata. are no t yet known. — An albinotie $ form among rutilus is pale yellow on upperside of forewings, grey to 
grey-brown on hindwings. Underside of forewings is not orange-yellow, but pale yellow. The grey ground 
colour of hindwings is retained but the yellow marginal band is very pale and poorly developed. The name 
hyalin a. hyalina Metzger scarcely corresponds to the description. — Among the spring and summer generations of 
rutilus one finds specimens having a black streak on underside of forewings from base to middle of wing 
fulgurata. below the cell: fulgurala Metzger. 
dido. Ch. hippothoe L. — dido- 5 Gerh. probably belongs here. The form is similar to candens discussed 
already in Vol. 1, but the hindwings are not so darkly suffused. The black dots on underside of fore wings 
are not circumscribed by white. As the form is described from Turkey it may refer to a variety of thersamon. 
The name is omitted from the Staudinger-Rebel Catalogue. 
Ch. alciphron Rott. Among the race gordius Sulz. one sometimes finds $$ which are quite suffused 
flavescens. with yellow on forewings, whilst only the costa is yellow on hindwings. They are named flavescens Tutt. —- 
columbanus. columbanus Prunn. is described in a very old and inaccessible work. Higgins states they occur frequently 
in Limone and Crissolo (Piedmont), but unfortunately only gives a very brief description. The violet hue 
in a fresh $ is very striking but very variable in degree. occur with pure golden ground colour and again 
such with heavy black dusting in basal half of forewings and the entire hindwing except at its outer margin. 
The name diniensis Oberth. refers both to typical alciphron as well as to gordius, when the spots are absent 
on underside of same. — Similarly Verity has declared the name gordius ab. violacea Pionn. to be valid, 
although we already have alciphron ab. violacea Ksinsch. for specimens that are suffused with violet.
