22 ZYGAENA. By Dr. A. Seitz. 



privala. sequence of the extension of the spots. — On the other hand, the red spots can also be reduced to 4 small 

 (lots, :=! ab. privata Burgrli. — Larva dull white (cT) or greenish (?); on the back rows of (juadrangular 

 black spots; above the legs a row of small black dots, above which there is a jellow line. Pupa black- 

 brown, in a straw-yellow cocoon. Jmago in July and later; on clearings in woods, several specimens being 

 often found sitting on one tlower. 



angelicae. Z. angelicae <). (5a). Forewing steel-blue, with 5 .spots, which are continent on underside. Hind- 



wing with a black distal margin of even width. The extreme tip of the antennal club has a yellowish silky 

 rioteschalli. gloss. — The j'ellow aberration already desciibed by Ochsenheimer is named ab. doleschalli by Ruhl. — 

 sexmaciila. ab. sexmacula Dziitrs. has 6 spots. — In ab. confluens Dziiirz. the spots are enlarged. — In S. E. Ger- 

 confluens. many, Austria, and the Balcan Peninsula; in the North of the area in July, in the south earlier. — In 

 trans- transcarpathlna Hormuz., from the Bukovina, the spots are small and edged with black. — Larva yellow, 

 carpathina. very finely dotted with black, two rows of black triangles on the back; in June on Trifoliuni montanum. 

 Pupa anteriorly black, in a golden-yellow cocoon. 



stoechadis. Z. Stoechadis Bkh. (^= lavandulae libit.) fiib). Entirely black, densely scaled, with a metallic dark 



green (rarely blue) gloss. Forewing with 5 spots. Hindwiiig likewise black, with red dots in the centre, 

 sometimes, esj)ecialiy in the ?, also the base dusted with red. Exceptionally there appear 6 spots in other- 

 wise normal black specimens. North -East Spain, and the French and Italian Riviera; verj' common. — 



jiulimmic. In judicariae Calh., from the Southern Tyrol, the spots of the forewing are thinly edged with white. — In 



ilulu'n. ab. dubia Sfff)-. (5 be) the red scaling of the hindwing is so extended that the black is reduced to a broad, 



siiuious, marginal band. According to this band being more or less narrowed by the expansion of the red 



colour, we have transitions towards tninsali>ina , the figures of niediat(ji)ih and charoii Bo'imL and o^ trana- 



alpina Hbn. representing such forms. Most similar to fransa/pina Exp., dealt with below, is a form sold by 



rnm/xiniae. Messrs. Stauwnger & Bang-Haas as var. campanlae (5 c), which comes from Italy. — As hadjina (5 c) I 

 hadjina. j-eceived fi-om the same firm a large 6-spotted Zygaena which resembles a g\gm\t\c fi/ipendiifae; from Tauria.*) 



— Larva dorsally deep yellow, with '2 subdorsal rows of black oval spots; sides lighter, with a row of black 

 dots; underside greenish; in May adult on Dorycnium sutfruticosum. Pupa brown, in a light-jellow cocoon. 



— The imago has a fast and active flight , often sailing for short distances without moving the wings, 

 appearing tpiite black. Near Genoa, Pegli and other places at the Italian Riviera this insect is, next to 

 Z. transalpina maritima, the commonest Burnet throughout June. Sometimes I have seen small swarms flying 

 about the tips of oak-trees at a height above the ground at which I have never observed other Zygaenae. 



cynarae. Z. cynarae Exp. {= millefolii Exp.) (5b). 5-spotted, the bod}' entirely without hairs, with metallic 



green gloss; wings very sparsely scaled, the colour a|)pearing pale. The abdomen bears a red ring which 



is more distinct at the sides than above. From the Rhine valley southwards to the Riviera and eastwards 



turatii. to the Ural and the shores of the Black Sea. — In ab. turatii Std/h. (5 c) the abdominal belt is entirely 



. missing above, appearing only as a lateral spot; North Italy, Dalmatia; near Pegli, at the Riviera, I met 



tricingidata. constantly with this form, while it occurs elsewhere only sparingly among the type-form. — ab. tricingu- 



lata Bur(jc(f has 3 abdominal belts, which, however, are usually red only above and laterally, not below. — 



genistae. In genistae H.-Sch. (= dahurica //.-.S'<7/.) (5d), from South France, Hungary and the Tyrol, the forewing is 



crntaureae paler and more transparent. — centaureae Fixch.-Wald. (od) has a stronger antenna and the 5. spot is pro- 



■ longed towards the hind angle. — Larva greenish above, yellowish grey at the sides ; subdorsal black dots, 



near which there are yellow spots; head greyish green; till June on Peucedanum oreoselinum. Imago in 



June, in the north of the area from Julj-. Sluggish aiul clumsy insects; the individuals occur more singly, 



there being apparently no decided flight-places as is the case with other Burnets. 



anthyllidis. Z. anthyllidis Boisd. (= erebus Meuj.) (5e). With pale collar and light-red belt. The wings strongly 



widened, and especially the fi spots of forewing enlarged, being more or less quadrangular. Pyrenees. — 



flava. ab. flava Oberth. is the yellow aberration. — In caucasica Sff/r.-Reb. (be) the pale collar is missing, 



caucasica. ^nd the two distal spots touch each other or are confluent; from the Caucasus. — Larva yellow, with the 



head, thoracical legs and transverse bands black; on Trefoil. Pupa in a white ovate cocoon of which the 



frontal end is directed downwards (ObekthOr). 



filipendnlae. Z. fllipcndulae Z. (5et). 6 rather large spots on forewing; no abdominal belt. At once distinguish- 



able from the tranmlpimi-iovms by a different red, broader wings, and especially by the underside of the 

 forewing having a greyish silky lustre and bearing indistinct red clouds. Throughout Europe, except the 

 flava. high North, also in Asia Minor and Armenia. — ab. flava ffobson is the (accidental) yellow aberration. 

 chrysan- — Also the occurrence of ab. chrysanthemi Bkh. (5e), in which the sjiots of forewing and the hindwing 

 themi. are brown, appears to be due to chance, as it has formerly been met with several times in some numbers 



') hi Staudinger-Rebel, Cat. Lep. Pal. Faun., this foini is enumerated as a transition towards filipendulae.
