this species uDdcr the same uame, and, therefore, even supposing 

 Griienee to be correct in saying that this \» Sohenwartluana oi Grerman 

 authors, Haworth's name would take precedence (1812), Ti'eitschke's 

 description not being published till 1830, while Schiffermiiller's name 

 (1776) was published without a detailed description, and therefore 

 cannot well be identified. 



The synonymy of this species will therefore be 



{Cato])tria, Gu.) Scopoliana, Haw., Steph., Wood (988). 



Hohenwarthiana, Gn., Wilk. («o» Tr.,&c.). 



It occurs commonly among Centaurea nigra, upon the seeds of 

 which the larva appears to feed, and not especially among thistles, as 

 stated by Wilkinson. 



I suspect that much of the confusion in which these three species 

 have been involved has arisen from the fact that cana is variable, and 

 both the others rather local — falcana very so, and ScopoUana ap- 

 parently unknown in Germany, although it certainly occurs in France. 



Haworth collected in Norfolk, where all three species are common, 

 and no doubt was well acquainted with them ; but Stephens mixed the 

 names, making carduana, Gn. (cana) synonymous with ScopoUana, 

 Wood, although they are obviously distinct. Dr. Wocke also has 

 mixed them hopelessly ; but he marks carduana, Gn., as unknown to 

 him, and had not therefore a fair chance of quoting correctly. 



Catoptria aspidiscana, Hiib. — Recorded as British in the Entomo- 

 logist's Annual for 1868, p. 110, but without description. Stephens 

 (Illust. 4, p. 120) describes an insect under this name, which may be 

 this species, but in his Museum Catalogue he removes it to his list of 

 reputed British species. Wood's fig. 978 (aspidiscana) seems to be a 

 male Carpocapsa grossana ; therefore, I think it best to append a 

 description. 



(J . Head, antennae, and palpi dark grey, face whitish, thorax dark brown, pa- 

 tagia paler. Ground colour of fore-wings pale grey, nuich streaked longitudinally 

 with darker, basal patch reddish-brown (with a tinge of olive at the base), acutely 

 angulated exteriorly. Central fascia also reddish-brown and angulated, the colour 

 being produced from the angle above the ocellus. From the costa, beyond the fascia, 

 arise eight short silvery streaks, the first and last being the longest. Ocellus silvery, 

 enclosing three black lines, the outer ones thick and distinct. Cilia mixed reddish- 

 brown and pale grey. Hind-wings grey with paler cilia. 



$ . Darker in colour. Fore-wings shorter and more truncate. 



This species has a general appearance of being pervaded with 

 longitudinal dark streaks. 



According to M. Jourdheuille's Calendar, the larva feeds in silken 

 tubes in the midst of flowers of Solidago virgaurea and Chrysocuma 

 Unosgris.
