ANTHKOCERA LONICER^i. 469 



a. ab. semilutescens, Hewett, " Ent. Eecord," i., p. 60 (1890). Base of pos- 

 terior wings orange. York. 



0. ab. lutescens, Hewett, "Ent. Eecord.," i., p. 60 (1890). - Two posterior wings 

 orange. 



The specimen, bred by Mr. Hewett, from which this aberration 

 was named, is an isolated example, in which the red pigment of the 

 hind-wings has largely failed. The wings are of an undefined orange- 

 red colour, fading to yellowish on the outer margin. 



, 7. ab. citrina, Spey., " Stett. Ent. Zeit.," xlviii., p. 334 (1887). Flava, Oberth., 

 "Etudes d'Ent.," xxth. liv., p. 43, pi. via'., fig. 148 (1896). Agrees exactly with 

 typical German A. lonicerae, except in colour. The size is the same, the apex 

 of the fore-wings sharply pointed, the margin oblique, the ground colour inclining 

 to green. The spots and hind-wings of a clear light yellow, between straw- and 

 citron-yellow, on the underside scarcely any paler (Speyer). 



This form was first mentioned by Ochsenheimer, who writes : I 

 possess an aberration, which, instead of red, is of a very beautiful yellow 

 colour ; a similar is found in Gerning's collection (SchmeU. i~on Europa, 

 ii., 52). Speyer, who first described the form " with yellow spots and 

 hind- wings" as ab. citrina, remarks that the specimens described by 

 him were taken in Silesia, by Teicher, who found single examples in 

 different years until 1887, when he captured some 20 examples and 

 three transitional ones. This was the first time that the transitions 

 had been noticed, and they were still much rarer than the true 

 aberration. He further notices that the aberration was a little later 

 in emergence than the type form. Caradja observes that it has occurred 

 in Eoumania, Bellier-de-la-Chavignerie has captured it in the Cevennes, 

 and Killias near Tarasp. 



8. ab. chalybea, Meves (? M.S.) ; Auriv., " Nordens Fjaril.," p. 53 (1888). 

 Fore-wings strongly bluish, spots and hind-wings dark brown, the outer margin of 

 the latter bright cobalt-blue. Found on the rocky shores of Upland, by J. Meves. 



e. ab. achilleae, Hb.-Gey., "Samm. Eur. Schmett.," fig. 165 (1841). Bercei, Sand, 

 " Cat. Lep. Auv.," p. 23 (1879). Coiijluens, Selys. "Bull. Ent. Soc. Belg.," xxvi., 

 p. cxiii (1882). Hiibner's figure has no descriptive letterpress. It represents an 

 aberration of A. lonicerae, with spot 1 extended along the costa for some dis- 

 tance, 3 is joined to 4, 2 joined to 3 + 4 by a fine upper line, and a fine central 

 one ; 5 enlarged and joined to 3 + 4 centrally by a thick red line. The fore- 

 wings have the shape of undoubted A. lonicerae, and the hind- wings are quite 

 typical of this species. 



Blotched examples, in which all five spots are united, are, in this 

 species, comparatively rare. Oberthiir records one in which the spots 

 are confluent on the left fore-wing, and separated on the right. Sand 

 notes bercei as a rare aberration from Nohant, in which all the spots of 

 the fore-wings are confluent. Oberthiir has obtained one blotched 

 example of this species only from Cauterets, where the type is very 

 common, and Speyer one on the Rigi, among numbers of the type ; an 

 example with entirely red fore- wings is recorded from Soultzmatt, by 

 Peyerimhoff. Boisduval writes that the form with an irregular band 

 is very rare. British localities are York (Hewett), Chattenden (Bower), 

 Wyre Forest (Abbott) ; several others are in British collections labelled 

 " Coventry," but we know nothing of the captor of these. Selys states 

 that he has received from Halloy a single example, in which the basal 

 spots are united with the median and with the posterior by a band. 



f. ab. eboracae, Prest, "Entom.," xvi., p. 273 (1883) ; "Proc. Ent. Soc. Lond.," 

 1883, p. xxviii. Not quite so robust in appearance as Zygaena lonicerae. The 

 anterior wings look a little more pointed than those of that species, their colour is 

 steel-blue, and they are more sparsely covered with scales than are those of Z. loni- 

 cerae ; posterior wings and spots pink, not crimson ; the border of the posterior wings 

 is brown, not black ; and the cilia of all the wings whitish, instead of black, as in
