This very natural group was first distinguished as a genus by 

 Mr. Haworth in his Lepidoptera Britannica^ under the name 

 of Scoparia, which having been applied by Linnaeus to a genus 

 of plants, we have been compelled to substitute another. 



Eudorea being closely allied to Fabricius's genus Phycis (a 

 name which must also fall, a group of fishes having been pre- 

 viously designated by it), we may observe that the antennae of 

 Phycis in the males appear to be incrassated towards the base, 

 from the joints there producing a bundle of scales (from whence 

 arises our trivial name of knot-horn), the wings when at rest 

 are convoluted, and the labial palpi recurved. 



Many species of Eudorea being found upon the trunks of 

 trees, stone walls and paling, we suspect the caterpillars are 

 Lichen feeders. The following is our list of British species. 



1. E. Cembrae Haw. Lep. Brit. p. 498. n. 1. — Cembrella 



Linn. ? Fab. ? 



2. dubita i/aw.— dubitalis Hiih. 



3. subfusca Haw. 



4. Pyraiea Haw. — Pyralella Hub. 



5. Mercurea Haw. — Mercurella Linn. — Crataeffella Hiib. 



6. murana Nob. 



7. lineola Nob. ^irom Mr. Plastead's collection : very like 



the preceding, but the under wings have a sinuated 

 line across them. 



8. Resinea Haw. — Resinella Linn. ? 



9. pallida Nob. — from Whittlesea Meer. Wings short, 



broad and pale. 

 10. angustea Nob. — from Tonbridge Wells. Wings long 



and very narrow. 

 E. murana has received its name from being found upon 

 walls ; it has a more ochraceous with a slightly green tinge, 

 and is more thickly speckled than any of the other species. I 

 took a specimen on the 9th of July 1825, upon a stone wall 

 near Aberfeldy in Perthshire, and saw another in a similar 

 situation a few days after in the neighbourhood of Schecallien. 

 The plant is Saxifraga stellaris (Hairy Saxifrage), from the 

 shady and moist sides of mountains in Scotland.
