66 THte ENTOMOLOGIST. 



ab. navarina, Selys-Longchamps, * Enumeration des Insectes 

 L^pidopteres de la Belgique' {v. supra), p. 19, 1845. His de- 

 scription reads as follows* : — " Toute brune en dessus avec une 

 serie anteterminale de taches fauves. Le dessous des ailes 

 plus noir qu'a I'ordinaire." He states that he is describing the 

 insect figured by Ernst & Engramelle, * Papillons de I'Europe,' 

 vol. ii. pi. Ixii. suppl. viii. figs. 31 c,/(1780), and referred by 

 them, p. 252, to Esper, ' Schmetterlinge Europas,' i. p. 382, 

 which is his description of dictynna illustrated on pi. xlviii. 

 (suppl. xxiv.). S6lys-Longchamps consequently remarks that 

 the absence of the black spots in the outer band un. s. h. w. at 

 once removes it from dictynna, and, indeed, Ernst & Engramelle 

 refer their figures back to their first volume, pi. xix. fig. 31, and 

 the corresponding letterpress, pp. 67, 68 (1779), where a further 

 reference is made to the previous plate of Esper (i. pi. xlvii. 

 suppl. xxiii.), which represents athalia. The following descrip- 

 tion is made from the figure to which Selys-Longchamps 

 refers : — 



Up. s. f. w. : Ground colour only shows between the subterminal 

 lines and in a single spot outside, and two inside the stigma; on 

 h. w. only between the outer and inrier lines, and in the Hght spot. 



Un. s. f. w. : Lunules yellow, with a few yellow spots below the 

 costa and about half-way down the wing inside the outer sub- 

 terminal ; beyond this the whole wing is fulvous, with a series of six 

 long, rather wedge-shaped, black dashes starting from the inner sub- 

 terminal, a square black spot taking the place of the stigma, and an 

 oblong black spot in the middle of the base representing the basal 

 dash. 



Un. s. h. w. : Terminal band shows dull grey spots near the arch 

 of the lunules except at anal angle ; inner part of the outer and 

 central bands black ; outer part of central band pale yellow : rest 

 of wing fulvous, except the light spot and the first, third, and fourth 

 spots of the basal band, which are of the same shade as the spots 

 in the terminal lunules. (This colour may have changed in the plate.) 



A variant of this aberration is figured, without name, by 

 Hiibner, ' Beitrage,' ii. pi. iv. fig. W. 1, 2, the underside of 

 which has the outer part of the fore wing very pale, the spots 

 forming the elbowed line prolonged into dashes, the stigma and 

 the space between the basal lines being filled in with black, and 

 the basal dash being represented by a triangular black spot. The 

 hind wing appears to have the usual bands, but the outer has the 

 dark lunules very slightly represented, and failing altogether to- 

 wards the costa, the space between them and the central band 

 being filled in with black in the lower half of the wing ; most of 

 the base is also black. 



A Dutch specimen referable to this form is also illustrated 



* "Entirely brown above, with an antemarginal series of orange-brown 

 spots. The under side with more black than usual."
