IS72.1 27 



Wood! ! Haworth's subseipiuiia is now well known to liave been pyy- 

 mceana, Hiibnei" (No. 1210 of AVocke) ; while Wood's siihsequana is 

 Pamplusia ononticolana (wMcli is Wocke's INTo. 1243). 



It seems, therefore, not improbable that these three supposed 

 species (Nos. 1282, -3, and -4) may all be referable to pJii,mbagana, 

 Treitschke, although some of the synonyms belong elsewhere. 



M. Jourdheuille, in his Micro-Lepidopterist's Calendar, states 

 that the larva of this species feeds in roots of Achillea millefolium. 



D. senectana, Grn. — Introduced in Mr. Doiibleday's list, but with- 

 out description. Called by Wilkinson the ? of his saturnana, from 

 which it is very distinct. 



Described by Guenee — "Allied to ulicana {i. e. plumb ana), h\xt 

 " larger and paler, wings of the same foi'm as caliginosana (simpUciana), 

 " cinereous, irrorated with very numerous yellowish scales, in fact, 

 " almost covered with them, nearly immaculate. The dorsal patch and 

 " marginal sjDots scarcely visible. Costa wdth lead-coloured strigulae. 

 "Posterior wings cinereous. Palpi elongated as in ulicana.'''' 



This description is excellent. The insect appears to be light 

 bi'own, from the almost total absence of leaden lines and the abun- 

 dance of yellow scales. Alar. exp. 7 lines. 



Apparently a scarce species in this country. I have seen but 

 two or three specimens, one of which is the type named by Guenee, 

 and kindly lent me by Mr. Doubleday. 



D. herhosana, n. sp. 



^. Head and antennae pale brown. Palpi whitish, tip brown. 

 Thorax pale brown. Pore-wings with the costa rather arched and the 

 apex pointed, rich brown, with numerous small bright yellow scales, 

 arranged in short irregular lines, not very close together, but allowing 

 the ground colour to appear. Dorsal blotch triangular, oblique 

 pointed at the apex, pale brow^n, darkly margined on hoth sides, and 

 enclosing several faint bi'own lines on its base. Costal streaks short 

 and indistinct, pale silvery. Above the anal angle, and parallel with 

 the hinder margin of the dorsal blotch, is a long, narrow, irregular 

 space, margined with a silvery line. Two or three of the usual blacJv 

 dots are barely visible at the hind margin. Cilia shining, pale yellowish. 

 Hind- wings whitish, tinged wdth grey. 



? . Darker, especially on both sides of the sharply defined and 

 nointed blotch, and with fewer yellow scales. Hind-wings brown. 



Alar. cxp. 7 lines.
