130 BRITISH BUTTERFLIES. 



is occasionally noticeable (ah.rufina, Obth.). The marginal black spots 

 are sometimes edged externally with "white (alboniarf/inata) or blue 

 (caeruleomarginata), whilst the discoidals, usually simply a dark lunule, 

 are sometimes ringed with white on all the wings (albncuicta), or with 

 blue (caeruleocincta), or they may be replaced by white spots (albopuncta) 

 or blue spots (caeraleopuncta) ; sometimes these characters occur on the 

 hindwings only (postieoalbocincta, etc.), at others on the forewings only 

 (anticoalbocincta, etc.). The marginal spots are frequently edged 

 internally with white (alb < dam data) or with blue (ca<>r\tleoitin\data) 

 lunules, whilst a large wedge-shaped streak, sometimes white 

 (albocuneata) at other times blue (caerideocuneata) stretches across the 

 disc of the hindwing. Rarely, especially in the very blue forms, the 

 costa is white = albicosta. In many examples the various markings are 

 combined and the aberrations are very interesting. So complicated, 

 however, are the combinations arising from the modification of the 

 orange lunules, pale lunules, blue scaling, whitish shades, etc., that a 

 tabulation of the various forms is most difficult. The following, 

 however, is based on examples that are either in our possession or have 

 come under our notice — 



1. — Brown without any orange marginal lunules = ab. fusca, Gillm. 



2. — Brown with orange marginal lunules on hindwings only = ab. thersites, Gerh. 



3.— Brown with orange marginal lunules on all the wings — icarus, Rott. 



4. — Like 3, but with pale interneural lunules towards apex of forewings = ab. 



apicata, n. ab. 

 la. — Like 1, but with pale* lunules internally edging the marginal area = ab. fusca- 



albolunulata, n. ab. 

 2a. — Like 2, but with pale lunules internally edging the marginal area = ab. 



thersites-albolunulata, n. ab. 

 3a. — Like 3, but with pale lunules internally edging the marginal area = ab. 



albolunulata, n. ab. 

 4a. — Like 4, but with pale lunules internally edging the marginal area = ab. 



apicata-albolunulata, n. ab. 

 lb. — Like 1, but with pale* wedge-shaped mark on hindwings = ab. fusca-cuneata, 



n. ab. 

 2b. — Like 2, but with pale wedge-shaped mark on hindwings = ab. tlwrsites-cuneata, 



n. ab. 

 3b. — Like 3, but with pale wedge-shaped mark on hindwings = ab. ipliis-cuneata, 



Tutt. 

 4b. — Like 4, but with pale wedge-shaped mark on hindwings = ab. apicata-cuneata, 



n. ab. 

 lc. — Like 1 (la or lo)f, but with the basal area of wings scaled with li!ae-blue = ab. 



fusca-caerulcscens, n. ab. 

 2c. — Like 2 (2a or 21>), but with the basal area of wings scaled with lilac-blue = ab. 



tliersites-caerulcscens, n. ab. 

 3c. — Like 3 (3a or 3b), but with the basal area of wings scaled with lilac-blue = 



caerulescens, Wheeler. 

 4c. — Like 4 (4a or 4k), but with the basal area of wings scaled with lilac-blue = 



apicata-caerulescens, n. ab. 

 la". — Like 1 (la or lb)\, but with the wings scaled with lilac-blue to beyond the 



diaco'id&l = &jb.fu8ca-thestyli8 } ' n. ab. 



* " Pale "= white or blue, etc.; when " white" then albolunulata, albocuneata, 

 when "blue" caeruleolunulata, caeruieocuneata, etc., these terminations being 

 added to all the following forms.
