a Genus of Tineidce. 125 



Sp. 8. Populetorum, Zeller. (PI. XIV. fig. 11.) 



Alis anticis osseis, vel purpurascentibus, griseo-nebulosis, pimcto 

 costali post medium, duobusque distantibus supra plicam 

 nigris. 

 Populetorum, Zell. Isis, 1839, S. 269 ; Linn. Ent. ii. 330. 



The dark-coloured specimens of this insect have some resem- 

 blance with Falconipennclla, but Populetorum may always be at 

 once recognized by the distinct black spot beyond the middle of 

 the costa. 



Expansion of the wings 6 — 6| lines. 



Head and face greyish yellow ; palpi yellowish, the terminal 

 joint brown, with the apex yellowish ; antennae yellowish, with 

 brown annulations ; thorax greyish yellow ; abdomen grey, be- 

 neath yellowish ; the four anterior legs have the femora and tibiae 

 dark reddish brown, the tarsi shining whitish, at the ends of the 

 joints brown ; the posterior legs have the femora yellowish grey, 

 tibiae and tarsi dirty whitish, the joints of the latter with the ends 

 brownish. 



Anterior wings pale yellowish purple (a specimen sent me by 

 Herr Zeller is entirely of dirty bone colour), with some cloudy 

 grey markings, forming the usual costal triangle ; behind the 

 hinder margin of this triangle is the conspicuous black spot, and 

 along the costa are various other small blackish spots ; a small 

 black spot lies in the fold of the wing, near the apex of the costal 

 triangle, and another larger one lies on the fold, towards the anal 

 angle; apical cilia purplish brown, inner marginal cilia grey. 



Posterior wings shining grey, with purplish grey cilia. 



A scarce species. I once took it in Birch Wood, September, 

 17th, 1846. It is also in the collections of Messrs. Stephens, 

 Curtis and Douglas. 



Zeller states that " it was several times bred by Fischer von 

 Roslerstamm from larvae off birches and aspens, and that he him- 

 self had taken fine specimens in June and July, almost only in 

 unmixed aspen woods ; yet that in April and May he obtained 

 specimens which were wasted, and appeared to have hybernated." 



Sp. 9. Inconstans, Stainton. (PI. XIV. figs. 1 — 7.) 



Alis anticis ochraceo-rufis, triangulo costali non dilutiore, brunneo- 

 rufo marginato, nebulis brunneo-rufis apicem versus ; femo- 

 ribus tibiisque quatuor anterioribus brunneo- vel cinereo- 

 rufis, femoribus tibiisque posticis albidis (fig. 1, 2).
