Original description. — Tinea alis auratis, maculis fasciaque 

 media purpureis. Parva. Corpus nigrum. Antenna? breves nigra?. 

 Ala? antica? aurea?, nitidse. Macula? dua? purpurea? ante medium ad 

 marginem crassiorem. In medio fascia lata purpurea ad marginem 

 crassiorem bifida, versus apicem denique adhuc macula purpurea. 

 Ala? postica? aurata?, immaculata?. Habitat Kilia? (Kiel), Dom. 

 Daldorf (Fabricius, Mantissa Insectorum, No. 131, p. 253). 



Imago. — Fore-wings 8-9 mm. ; shiny, light golden-green, with red 

 costal spot near the base, an oblique fascia before the middle, another 

 beyond the middle forked on the costa and joined to a costal spot 

 towards apex (the latter spot is sometimes absent). Hind- wings pale 

 grey, with a purplish tint towards apex. 



Variation. — Zeller describes [Linn. Ent., v., p. 334) two forms 

 of this species as follows : — 



1. — Capillis ferrugineis; alis ant. saturate aureis nitidis, humero, macula 

 transversa costaa prope basim maculaque maxima postica costam ter tangente 

 purpureis = rubrifasciella , Haw. Haworth's original description reads as follows : 

 " Tinea rubrifasciella (The red-barred Gold), alis aureis fasciis quatuor rubro- 

 purpureis. Expansio alarum 4 lin. Alas anticaB saturate aurea? metallicse fasciis 

 quatuor sequidistantibus rubro-purpureis ; prima basi : secunda, aliquantulam 

 arcuata ante, tertia pone medium et ad costam bifida ; quarta limbi postici, juncta 

 ad tertiam juxta marginem tenuiorem. Cilia fusca. Postica? fusco-cupreae, 

 praecipue pone medium. Habitat in Cantio, at valde infrequens " [Lep. Brit., No. 

 41., p. 572(1828)]. 



2. — Macula postica in duas soluta, priore costam bis tangente. 



Treitschke describes his anderschella, also considered a form of this 

 species, as : — 



3. — Alis anticis purpureis, maculis saspius confluentibus aureis = ander- 

 schella, Tr. 



One form given by Zeller as a var. of M. aureatella is referred 

 here. This is : 



/. — Ut a (=allionella, ¥.), sed macula postica ad marginem posticum usque 

 producta = paykullella, Thunberg, described as " Alis purpureis, fasciis 3 aureis " 

 (Diss., iii., p. 101). 



Habitat. — The habitats of this species vary exceedingly. In some 

 places it abounds on the chalk-hills, as at Cuxton in Kent, in others 

 it is equally abundant in fenny districts. In Bohemia it occurs on the 

 sand-hills, and in Livonia, in the bushy districts on chalk-hills. Farren 

 says that in Chippenham Fen, in 1891, the species was to be found 

 swarming about the bird-cherry and fir-cones. (It was so abundant 

 that he boxed fifteen specimens in one large chip-box, off a single 

 cone.) He states that it is more abundant on a close, warm day, soon 

 after noon ; the firs on which this species was found were growing on the 

 outside of a belt of trees in the Fen, the bird-cherry among the less 

 thick parts of the ordinary fen growth. Hodgkinson reports it as 

 swarming under the shade of a yew-tree, at Grange, in 1873 ; whilst, 

 at the same place, Shuttleworth records it as flying in the partial 

 shade afforded by beech and fir trees in 1882. Bower has found it flying 

 in the afternoon sun, and has taken it by beating and searching 

 fences and tree-trunks in various localities in Kent and Surrey. At 

 Grantham, Atmore has obtained it by beating hawthorn, the moth
