2 [June, 



the first bounds a triangular speculum, as mjilumhana. Four blaek spots before the 

 leaden cilia, and the costa distinctly streaked with leaden. Hind-wings grey, with 

 concolorous cilia. 



I now think that my specimens (No. 3) from the Isle of Wight 

 and Hungerford, Wilts, arc merely small specimens of this species 

 (indeed, they agree in size better with Gucnoe's dcscriptioii than does 

 our ordinary form), and that those from Galway (No. 7) are darker 

 specimens of the same. 



For the species (No. 2) formerly mixed with the last, but having 

 a distinct costal fold, of which I recorded specimens from the coast of 

 Pembrokeshire, and at Plymouth, and which seems to occur along the 

 south coast, I think that we may safely adopt the name of senectana, 

 Guenee, which has been so long, doubtfully, included in our lists. 

 Guenee seems to have disregarded the costal fold, but otherwise his 

 description is sufficiently accurate. 



Allied to ulicana, but larger and paler. Anterior-wings of the form of cali- 

 ginosana (simpHciana) , hoary grey, irroratcd entirely with Tcry numerous yellow 

 scales, almost immaculate. A dorsal spot and marginal dots scarcely perceptible. 

 Costa streaked with leaden. Cilia leaden, separated by a white line, as in caligino- 

 sana, and furnished with a little apical tooth. Ilind-wings grey. Under-side of all 

 the wings hoary, silky, with a greenish gloss. 



To this it only seems necessary to add, "Costa folded in the male." 

 To this species I think that my rather smaller specimens (No. 4) from 

 Teignmouth and Darlington belong, and also the single specimen from 

 Zeller (having Heinemann's label), which has the costal fold. The 

 other two (No. 8) must be saturnana, Gn. Though yellower than 

 our specimens, there is nothing to separate them specifically. Neither 

 is there any very apparent distinction between saturnana and senectana, 

 until under a magnifier the fold becomes visible. The folded costa 

 produces a slight difference in shape, which is evidently referred to 

 by Guenee when he writes, "Anterior-wings of the/or/« of caliginos- 

 ana " — a folded species. Heinemann mc\\idie^ jplu')nha7ia and saturnana 

 in his section of the genus DicJtrorampha, which is without the fold. 



When recently looking through Dr. Mason's magnificent col- 

 lections at Burton-on-Trent, I found in his series of Sericoris alternana 

 (Daleana), from Scotland, specimens deviating from the usual uni- 

 colorous type, in the direction of showing darker fascia) across the 

 anterior-wings, and others in which these markings were sharply and 

 distinctly defined, agreeing exactly with types of metallicana, Hiib., 

 formerly sent mc by Professor Zeller.
