• ab. coerulescens-completa. — ab. fusca-fulva Tutt is brown without blue, but with orange coloured lunules and 
ab. fusca Tutt is brown with blue and without orange lunules. — ab. extrema Tutt. is coloured entirely black-brown 
with blue scaling up to behind the disc in forewings and up to the outer margin in hindwings having besides 
well developed round marginal spots. — If in this form there are still orange coloured lunules then it is named 
extrema-fulva Tutt ; if the blue is confined to base of wings we have extrema-restricta Tutt and if with this 
latter form we have again the orange lunules it is named extrema-completa Tutt. — ab. nigrescens Tutt is 
completely black-brown without blue and without lunules; similarly but with orange coloured lunules we have 
ab. fulva-nigrescens Tutt. Variations of markings occur in $ ab. striata Tutt (= extrema Courv.). Upperside 
is brown dusted with blue at base of hindwing. A yellow spot in anal angle. On underside of forewings there 
is a discal spot extended to form a black crescent and a few spots of the submedian row are extended to form 
streaks. The spots of submedian row on hindwings are changed to streaks towards the base. In the anal angle 
there are 2 yellow anal spots. — The $ ab. latimargo Courv. is distinguishable by unusually wide black margin 
to all wings. — In the neighbourhood of Bale Courvoisier captured an albino specimen in 1895. — There are 
also new denominations of the subsp. coretas 0. (Vol. 1, p. 298). The ab. diminuta Vrty. occurs only in the first 
generation and is said to be smaller and appear paler than any other form of the second generation, ab. 
luteumfera Vrty. is a highly unnecessary superfluous denomination as alcetas Hbn. shows the identical spots in 
the illustration which have moved Verity to give this denomination, only Hubner did not mention them 
specially in his description. — ab. semicaeca Krul. is entirely or almost entirely without ocelli. — metallica 
Courv. denominates specimens bearing anal spots with metallic markings on the hindwings, whilst in rufo- 
maculata Courv. these anal spots are filled with red. ab. pallida Pionn. is a pale french form from the Gironde 
and ornata Pionn. from the same district is a $ decorated with blue on the upperside like a — The form 
described as vernalis by Grund is identical with decolor Stgr. (Vol. 1, p. 298). dipora Mr. is not synonymous 
with parrhasius F. (Vol. 1. p. 298), it is a distinct subspecies occurring in the Khasia Hills at the same time as 
subsp. diporides Chapm. The latter also occurs in palaearctic territory in the N. W. Himalaya, Kulu and 
Kashmir. The summer form is darker on the underside than the european name type form and has a wider, 
darker margin on forewings. The red spot at anal angle of hindwings is more sharply outlined on underside. 
The spring form from the N. W. Himalaya compares with the summer form like the german polys per chon does 
with the summer form argiades. —- subsp. kawaii described by Matsitmura from Nihonkusu (Kiushiu) varies 
only little from parrhasius F. (illustrated Vol. 9, pi. 153 h). In the $ the round black spots surrounded with 
whitish-blue in cellules 2 and 3 without orange and the black streak in cellule 1 b is not interrupted and simi¬ 
larly edged with bluish-white. The anal spot is shorter, not extending beyond median vein. $ unicoloured 
brown, anal spots much larger, oval, each with a crescent formed orange coloured cap. 
E. ion Leech (Vol. 1, p. 298, pi. 78 b). From Hwei-si in the western Tsingling-Shan in east Kansu a 
new' race is described from the collection of 0. Bang-Haas which I am naming cellariusi in honour of our 
Editor. It is closely related to cratylus Fruhst ., but varies slightly from it by the delicate dove grey colouration 
of the underside which in a certain light takes on a pale silvery sheen. On the underside of forewings all spots 
of the discal band are deep black with a sharp white outline, increasing in size from the costa to the hindmargin: 
of the spots of the submarginal row only the 3 lowest are deep black-brown with a sharp white outline, whilst 
the 3 upper ones are only slightly darker than the ground colour and occasionally with a delicate white surround. 
All spots of both bands are conjoined through white surrounds, the black spots themselves lie internervally. 
The pale markings of the hindwings resemble those of cratylus, but the colouration is a pure white. In the 
submarginal band from the anal angle to lower median nervure there are 3—4 small metallic black dots of 
which the 2nd — opposite the tail — and the 3rd are the largest. Both are dusted with metallic blue-green 
scales and faintly surrounded towards the base with a reddish hue. There are also blue-green metallic scales 
in the anal angle towards the margin. — subsp. cratylus Fruhst. from Batang in Szechuan is larger than 
specimens from Ta-tsien-lu. On the upperside of forewings the white submarginal dots are absent and the 
underside of forewings is darker than in the name type form. Both wings are a delicate grey-brown on the 
underside. The discal area of the hindwings which in ion is only faintly circumscribed by bands is much more 
sharply outlined, it is a curious grey-brown with pure white edge. The subanal spot is more prominent. Pres¬ 
umably this is a rainy season form, whilst ion may be a spring form. 
29. Genus: I^ycaena F. 
L. argus L. (= aegon Schifj., argyrotoxus Bergstr.) (Vol. 1, p. 209, pi. 78 c). Of this widely distributed 
species a number of new races and forms are described, the differences between which are generally infinitesimal. 
Tutt differentiates according to colour the $ ab. caeruleus, a glossy violet-blue form and ab. lilacina a slightly 
paler shade which is closer to lilac or azure blue. — C ab. pallida Tutt inclines to pale pink, whilst ab. plumbea 
Tutt is blue-grey or slate, with fairly narrow black border and no discal band.
