from adornatella for the same reasons, and also in the slight curve of the second 

 fascia, which in this latter is angulated and ragged : from subornatella in its different 

 colour, and the want of the fascia-formed white cloud between the base and the first 

 fascia. Zeller took this species at the same time and place as the preceding, but 

 more sparingly, and the specimens mostly wasted, implying that it appears earlier 

 than thymiella. It may seem, to many entomologists, that species found hitherto 

 only in Sicily are hardly likely to occur in this country ; but if they call to mind that 

 Lithocolletis Messaniella, Gelechia vilella and Depressaria rotundella are species si- 

 milarly occurring in Sicily, but not in other parts of the Continent, the invalidity of 

 this objection will be apparent. Sicilian species will most likely be found on our 

 southern coast. 



Pempelia ornatella. Known among the species which have not the second fascia 

 angulated, by the first fascia being spotted with black on both sides and broadly in- 

 terrupted by the ground colour below the middle. This occurs in most parts of the 

 Continent, and nowhere scarce, frequenting dry places which are thickly clothed 

 with low weeds, in June and July. Here it appears to have become extinct, for 

 though in most old collections I know of no recent specimens. 



Pempelia subornatella (dilutella of my Catalogue). Differs essentially from orna- 

 tella in the deeper, much more brown-red ground colour ; in the completeness of the 

 two fasciae, which at least are never interrupted by the ground colour between the 

 medial and subdorsal nervures ; in the presence of a white fascia-formed cloud * be- 

 tween the base of the wing and the first fascia ; in the want of black long spots before 

 and behind the second fascia : it is distinguished from adornatella by the clearer 

 white of the anterior wings, the presence of the whitish fascia, and the slight angula- 

 tion of the second fascia ; and from sororiella and thymiella by its deeper brown 

 colour, its thicker fasciae on the anterior wings, &c. The larva feeds on thyme 

 {Thymus serpyllum), and the perfect insect occurs where that plant grows, at the end 

 of June and beginning of July. 



Pempelia adornatella. Distinguished from ornatella by its dirty reddish yellow 

 ground colour, by the strongly angulated second fascia, and by the brownish instead 

 of black spots on the anterior wings (excepting the two medial spots and the row on 

 the hinder margin) ; from subornatella by the want of the fascia-formed cloud between 

 the base of the wing and the first fascia ; from thymiella and sororiella by its much 

 darker and dirtier ground colour. This occurs in dry weedy places and meadows, 

 often along with ornatella and subornatella, in June and the beginning of July, at 

 Frankfort-on-the-Maine, Frankfort-on-the-Oder, Dantzick, Glogau and Vienna. 



Pempelia perjluella. Four, attracted by light, June 23, July 17, 21 and 27. 

 This species occurs twice in Guenee's Catalogue, — once as dubiella, and again as 

 perfluella. 



Ephestia elutella. Two, on palings at Lewisham, July 15 and 22. One of the 

 specimens appears a variety, with the first fascia straighter and more strongly mar- 

 gined, thus approximating to Ephestia biviella, F-v-R. 



Homceosoma sinuella. One, at Charlton, June 26. 



* This white fascia-formed cloud is much more distinct in some specimens than 

 others. Mr. Logan has a specimen, taken on Arthur's Seat, in which it is as bright 

 and distinct as the first fascia itself.
