frontal space red in front and black behind ; the antennce with basal joints yellow, 

 and the third black ; arista bare ; palpi black, with the tips a little dilated and pale ; 

 legs black, wings grey. This bears a considerable resemblance to the common F. 

 fucorum, but is paler in colour, less distinctly striped, and has the basal joints of 

 the antennte yellow. 



I hare a pair of these flies, which were given to me by tiie late Mr. Cooke, of 

 Bowdon.

BY EUSTACE R BANKES, M.A., E.E.S. 



In Lep. de France, Sppl., iv, 458, PI. 85, fig. 8 (1842), Duponchel 

 described and figured a Gelechiad under the name Lita unicolorella, 

 which some continental authors, including Wocke, have regarded as 

 probably identical with what we know as Arisfotelin tenebrella, Hb. ; 

 these have attributed the name tmicolorella, where used for an allied 

 species distinct from tenebrella, either to Zeller, who only used it in 

 MS., or to Herrich-Schaffer. Mr. J. H. Durraiit, however, informs 

 me that the late Monsieur E. L. Eagonot, who made a special study 

 of Duponchel's collection, made the following notes (probably on the 

 evidence of the type itself) in his copy of Staudinger's Catalog : — 

 (1) under Monochroa tenchreUa, Hb., " dele ' ? tmicolorella, Dp., iv, 

 85, 8,' " and (2) under Lamprotes unicolorella, H.-S., it is indicated 

 that" Dp., iv, 85, 8 " should precede the reference to Herrich-Schaffer. 

 Moreover, an examination of the original drawing for Duponchel's 

 work (now in the Merton library) strongly confirms Ragonot's identi- 

 fication of unicolorella. Dp., with unicolorella, H.-S. Zeller, who 

 originated the name, employed it in MS. for the same species, and 

 it is worthy of notice that Duponchel, Cat. Meth. Lp. Eur., 842 (1846), 

 writing under the title Butalis unicolorella, gives Germany as the only 

 known locality for it. 



Gelechia immaculafella was first described by Douglas in Trans. 

 Ent. Soc. Lond., N. S., i, 67 (1850), from a single specimen taken by 

 himself in West Wickham Wood in August, 1849. Stainton then 

 described it from the selfsame individual in Ins. Brit. Lep. Tin., pp.
