In ab. caerulea Courv. (1910) the $<$ have a pale blue uppersicle to all wings with a quite narrow black caerulea.

in the Valais which frequently show no red lunules together with blue colouration. — g ab. alcippe Stephens alcippe. 
is smaller than the name type form with narrower wings. Upperside blue with wide black border. Underside 
a rich grey; ocelli very pronounced as in the $, the inner row consists of 4 ocelli. — U ab. obscura approaches obscura. 
a melanic form as the entire upperside of the wings is so dusky that only when viewed from an angle 
a slight bluish sheen is perceptible. Underside normal. — ab. nigrescems Courv. also represents a dusky nigrescent. 
form. In both sexes all wings show a smoky grey to blackish ground colour on upperside and underside, 
the reddish lunules of fore wings as well as those of hindwings are suffused by a dai'k shadow. — 9^t 
resembling of hypochiona Rmb. viz: almost entirely white and with upperside pale blue, are named 
$ ab. caerulea Tutt. Margin is narrowly black and contrasts strongly from white fringes. On fore wings in place caerulea 
of orange lunules there are whitish patches between the veins. Hindwings show almost the same ground colour: 
dark black submarginal spots are edged with white and discoidal lunule of forewings is more strongly developed 
than on hindwings where it is almost extinct. — Courvoisier denominates and understands under the same 
name of caerulea 9? with a varying blue tone to the wings. — ab. falloui Tutt is a large 9 and has a blue caerulea 
colouration on upper and underside of all wings, but chiefly of the hindwings, as well as wliite discoidal lunules fallow. 
on all 4 wings. On underside of forewings white rays extend from the brown submarginal band towards the 
base. Underside is somewhat paler than in the name type form and shows the otherwise numerous black spots 
changed to white and besides the metallic green is absent from base of wings. —- The 9 ab. bninnea shows a brunnea 
uniform brown upperside without red marginal lunules; it occurs at higher altitudes in the Alps. — ab. duplex duplex 
Cock, appears to be a hermaphrodite, the right of upperside of hindwings is brown and the corresponding left 
side is blue. Actually however it was a 9- — 
Tutt has denominated a large series of $ aberrations which are only enumerated here as having been 
described, although it would have been better had they not been named $ ab. fuscus Tutt has a more 
dusky ground colour and $ ab. croceo-lunulatus Tutt has well developed orange spots on all wings. 9 ab. 
postcoerulescens Tutt is besides brown on upperside, only the hindwings with blue scales, 9 ab. coerulescens 
Tutt is identical with a similarly named form by Peters, Vol. 1, p. 300, and 9 ab. posterocrocea Tutt has 
the same appearance but it has orange lunules on all wings. -— $ ab. croceopostcoerulescens Tutt is brown 
with a few distributed blue scales on all wings and orange lunules on the hindwings, $ ab. croceocoerulescens 
Tutt is of similar appearance but it has an orange band on all wings, croceosemivirgatus designates 
brown 9? without blue, having only an orange band on hindwings, and croceovirgatus such brown 9? 
having all wings decorated with an orange band. $ ab. croceosemivirgatus-coerulescens Tutt has an orange 
band on the hindwings and blue dusting. In $ ab. croceovirgatus-coerulescens Tutt the orange band also extends 
to forewings and similarly blue dusting. According to Tutt these combinations also occur in insects with a 
yellow ground colour (— flavus) and then they are named: $ ab. flavolunulatus , $ ab. flavopostcaerulescens, 
$ ab. flavosemivirgata, $ ab. flavovirgata, $ ab. flavovirgato-coerulescens and 9 ab. posteroflava. Stauder 
denominates 9 ab. flavodentata from inner Istria showing throughout an albinotic tendency which also seems 
to extend to the CC belonging thereto. These do not show the typical dark violet blue so characteristic of mid- 
european specimens, but they appear to be pale and a very faint blue. Submarginal band is yellow-red and 
coherent on both wings. — 9? which show a decided reddish colouration on underside are named rufescens 
Tutt and those with a yellow ground colour ab. flavescens Tutt. — 9 ab- chrysophthalma Std. from Opacinor, 
Prosecco in the Karst has generally 6 dots occurring on the margin of hindwing on the underside with a pretty 
metallic gloss and without any sign of a black pupil. — The sizes are denominated as ab. major Tutt , insects 
with an expanse of 27 mm and minor Tutt for such as are of less than 23 mm expanse. Still smaller starved 
summer forms of scarcely 21 mm from Italy are named minutissima Tutt, these also occur in Lapland and 
are clearly a starvation form.

The variations of markings occur as in all Lycaenides in regard to the form, number etc. of 
the dots and bands and these have again become the subject of a superabundance of denominations. I am not 
certain if I have included all in those enumerated, ab. marginipuncta Tutt has well developed marginal spots marginip. 
on upperside of hindwings. — Insects with very wide margin are named lata-marginata Tutt, such with lata-marg. 
medium well developed black margin are ab. hitermedia-marginata and with quite narrow margin are ab. intermedia- 
angusta-marginata Tutt. With the latter 2 aberrations ab. angustimargo (Hosp. i. 1.) Vorbrodt is identical. — marginata.

in the disc of upperside of forewings; C ab. disco-posteriora Tutt has discoidal lunule only on upperside of hind- disco-obso- 
wings and $ ab. disco-lunulata Tutt shows the same well developed on upperside of all wings. — An additional (j an teriora 
dot between the discoidal lunule and base of wings is shown by C ab. unipuncta Tutt on upperside of forewing, d.-posteriora
