406 BRITISH LEPIDOPTERA. 



y. ab. pechmanni, Hartmn., "Mitt. Miinch. Ent. Ver.," iii., p. 35, pi. iii., 

 fig s - £ — 3 ( 1 ^79) ; Bartel, "Die Palseark. Gross-Schmett.," ii., p. 150 (1900) ; 

 Staud., " Cat.," 3rd ed., p. 100 (1901). — Head, thorax and abdomen brown or 

 green, the lighter markings on the thorax and form of the wings typical. The 

 usual central transverse band quite obsolete ; on the other hand a claviform spot, 

 which is to be seen in no other Sphingid, appears distinctly. The forewings 

 uniformly green or brown in colour as far as the paler band at the outer margin ; 

 on the apical part of the costa the usual light claviform spot. The underside of 

 both wings cinnamon-brown, with a lighter band at the outer margin; All the 

 specimens somewhat smaller than the type (Hartmann). 



A number of specimens were inbred by Pechmann, emerging in 

 1878, most of the individuals showing the normal range of variation, 

 but others, of both sexes, were peculiar in being without the median 

 band, but with a well-marked claviform spot towards the base. 

 Prout notes: "The figures show a very distinct and interesting 

 form, quite agreeing with the description — ground-colour uniform 

 dark brown or green nearly to outer margin, the marginal part, 

 which is normally green or olive, being of a sort of violet-grey 

 tint. The ambiguous reference to a k claviform ' spot seems to 

 have no reference to any remnant of a central band, for the figure 

 shows (as the description says) that that is absolutely wanting. 

 The figures have a lead-coloured or bluish claviform spot close to 

 the base of forewings." No doubt it is a peculiar modification of 

 Clark's ab. obsolete, with much darker ground-colour and an unusual 

 spot developed towards the base of the wing. Staudinger diagnoses 

 it (Cat., 3rd ed., p. 100) as: "Minor, al. ant. fere unicoloribus brunnes- 

 centibus, margine exteriore dilutiore grisescente." Hartmann notes 

 the aberration as coming from Nymphenburg, near Munich. Bartel 

 adds that "a specimen recorded from Crefeld is possibly only ab. 

 obsolete,, Clark, whilst the record that it occurs at Erfurt with the 

 type is open to doubt." 



8. ab. bipunctata, Clark, "Ent. Rec," i., p. 328, pi. A., fig. 3 (1891) ; 

 Ckll., "Ent. Rec," ii., p. 16 (1891). — The ab. bipunctata, has the ground colour 

 slightly more tinged with pink than figs. I and 2, and the outer margin rather grey ; 

 the transverse band is represented by a central spot and a smaller one on inner 

 margin ; hindwings tinged with yellowish, band not very distinct (Clark). 



Clark's aberration only differs from ab. maculata, in having a 

 small central spot, and an extremely small inner-marginal spot, whilst 

 the usual green tint is piactically wanting. Voelschow notes (Soc. 

 Ent., xv., p. 122) a ? in which the hindwings have a complete black 

 transverse band, whilst the forewings have the central area light ashy- 

 grey, the normal transverse band being broken into two quite small 

 spots, the upper of which does not touch the costa. 



f. ab. maculata, (Miitzel inlitt.) Wallgrn., "Skand. Het.," p. 15(1863); Lampa, 

 " Ent. Tids.," vi., p. 27 (1885) ; Buckell, "Ent. Rec," v., p. 276 [nee reference to 

 ab. ccntripuncta) (1894) ; Staud., "Cat.," 3rd ed.. p. 100 (1901). TiUae ab., 

 Clark, "Ent. Rec," i., p. 329, pi. A., fig. 9 (1891). — Fascia media alarum 

 anticarum in maculis dissoluta (Wallengren). 



Staudinger diagnoses (Cat., 3rd ed., p. 100) the form as: " Al. 

 ant. fascia media latius interrupta in duab. maculis dissoluta." Clark 

 notes (Ent. Rec, i., p. 329) of his specimen (fig. 9) : " Basal and 

 central area red, as in figs. 7 and 8, but of a more purplish tinge, the 

 paler outer parts of the wing well-developed, outer area greenish- 

 olive; central band broken into two spots, one central, and the other on 

 inner margin, better developed than in fig. 3 (ab. bipunctata) ; hind- 

 wings almost identical with those of fig. 5."
