232 THE entomologist's record. 



aberrations with two very clear figures (which he abstained from 

 naming). 



1. Var. arsilacJie, ab. $ . 



" Supra obscurior, nigricans, subtus al. ant. pallidioribus maculis 

 paucis nigris, post, fusco rufoque mixtis, fasciis mediis flavescentibus 

 nullis." 



"On July 28th, 1899, I obtained on the Mahdern des Mieslkopfes 

 two especially dark females, which instanced the extreme of this 

 variety, and I give the following description of the darkest specimen. 

 The expansion reaches 38mm. The upperside dark red-yellow, lightly 

 blackish powdered, the basal part of the fore- and hindwings black. 

 On the forewings the black streaks in the middle cell very strong, also 

 the angular spots of the row in the disc adjoining them, the round 

 spots beyond very large (1.5mm. to 2mm. expanse), and from cell 3 to 

 the neighbourhood of the apical part run together into a band, the 

 border black, with red-yellow powdering between the veins. On the 

 hindwings the transverse streaks feeble, the round spots large, the 

 border black with dark red-yellow roundish spots. 



" The underside of the forewing is dull coloured, the black marking 

 on the cross vein, a transverse line in the centre of the middle cell, and 

 four black round spots in cells lb, 2, 3, 4 restricted, the yellow apical 

 spot very dark with rust-brown tinge. The hindwings rust-brown and 

 rust-red mingled, with three small, silky shining white spots at the 

 base, three larger ones in the disc, a similar one in cell 2i, and round 

 marginal spots from cell 3, of which the two last in cells 7 and 8 are 

 yellow. 



" The description of the underside exactly agrees with the Tyrolean 

 local race. 



" With the smaller dark race from N. Finland the Tyrolean speci- 

 mens have no similarity whatever." 



2. Var. napaea ab. 2 . 



" Supra fascia antemarginalia lata nigra." 



Galvagni says that he caught this aberration, a ? , in cop. with an 

 isis $ . At the same time there were many pairs, mostly uh males 

 with napaea females. 



" The specimen is especially characterised by the marginal black 

 spots on the fore- and hindwings having run together. The basal part 

 of the forewing is blackish suffused, of which the spot bands are pallid, 

 those of the hindwing bright red-yellow. Below the black markings 

 are absent up to the transverse vein ; the hindwings as in normal 

 variegated specimens." 



I take this form to be simply a step towards the next aberration, 

 which is from the figure a very fine form. 



3. Var. napaea, Hb., ab. 



"Alls supra nigerrimis, virescentibus, maculis marginalibus (prae- 

 sertim in al. post.) flavescentibus subtus ut najiaea, Hb., al. post, 

 maculis nigro-fuscis (uec rufis)." 



" Almost at the same time as the former aberration I took at the 

 same place a unicolorous melanic specimen, which by reference to the 

 marking of the underside belongs without doubt to this variety. The 

 example, a truly magnificent specimen, is quite freshly emerged; 

 the expansion of wing is 39mm. Antennae as in a normal napaea. 

 The basal parts, particularly on the hindwings, abundantly furnished
