The type of Latreille's genus Botys [Phaloena piirpuraria 

 Linn.) being a Geometra, I have adopted Schrank's name to 

 avoid confusion; and I have not divided the group into genera, 

 because I am not satisfied with Treitschke's characters : but 

 when the structure of the insects and their ceconomy are suffi- 

 ciently understood, they probably may be formed into several 

 genera with great advantage. 



The following is a perfectly new arrangement; it includes 

 some insects unnoticed as British, and others hitherto placed 

 in genera to which they did not belong. 



1. S. Priinalis Wien. T.— leucophaealis Hub. 1. 12./.77.— albidalislTMA.lS. 



118. — nebulalis Haiv. but not o? Hub. 



2. S. olivalis JV. r.— umbralis Hilb. 8. 52.— nivealis Fab.? Haiv. 

 .3. S. sticticalis Linn.? — tetragonalis Haw. — fuscalis Hub. 7. 45. 



4. S. Alpinalis? Hub. 1 0. 63 J . 27. 175 and 176 ? .— uliginosalis Curt. MSS. 



—Mr. Dale and myself discovered this Moth in July on the sum- 

 mit of Ben Lawers, and Craig-challoch, in Scotland. 



5. 3. asinalis Hub. 29. 185. — F'or specimens of this insect I am indebted to 



Captain Blonier, who took them near Teignmouth, Devon. 



6. S. diversalis J^tt6. 16. 102. 



7. S. Borealis Kob.—T\\e larva I took on a very high hill near Oban, in 



August: it fed upon the Solidago virgaurea {{A. 45); the moth 

 hatched the following June. 



8. S. pulveralis Hub. t. \7.f. 109. 



9. S. fuscalis W. T.— cineralis Fab.— Hub. 10. m.—Haw. 



10. S. Sambucalis W. V.—Hilb. 13. S\.—Haiu. p. 383.— This insect has 



lately been associated with the Hydrocampse of Lat., but it evi- 

 dently belongs to this genus. 



11. S. Verbascalis JF.V.— arcualis Hilb. 12. m.—Haiv. 



12. S. longipedalis Curtis B. E. pi. 312.— Taken by J. C. Dale, Esq. amongst 



brambles, at Weymouth Castle, Dorset, July 6th, and at Ryde in 

 the Isle of Wight. 



13. S. ferrugalis Hub. 9. 54. & 23. \h(i.—Haiu. 382. 



14. S. flavalis W. V.—Hiib. 11. 69.~Haw. 381. 



15. S. institalis HUb. 29. 182.— lutealis Haiv. but not o( Hilb. 



16. S. ochrealis Hilb. 22. 146.— Haw. not P. Verbascalis Hiib.9. 59, which 



is the B. Pandalis Treit. 



17. S. hyalinalis Hilb. 11. 74. — Haw. 377-— July, Darent-wood. 



18. S. cinctalis Treit. 7. 97.— Hmbalis Hiib. 11. 72. & 73.— Haw. 



19. S. angiKtalis Haw. Lep. Brit. 2}.379. n.8. — b. June, New Forest, Mr.Dale. 



20. S. tenninalis Haiv. 379. 9.— July, Feversham. 



21. S. pallidalis Hatv. 379. 10. 



22. S. glabralis Fab.— Hilb. 10. 65.—Hatv. 



23. S. lancealis? W. T.— glabralis Fab.—Hilb.'\S.U7 ? .— longalis Haw.— 



June, Norfolk, and near Spitchwick Park, Devon. 



24. S. verticalis Li)in. — Hilb. 9. 57-— Bon v. 16. ;j/. 556. 



25. S. Urticaiis Linn.— Hilb. 12. 78.— Bon v. 10.;;/. 349. 2. 



26. S. palealis W. V.—Hilb. 11. 70.— Haw. 378.— Aug., Norfolk & Dover. 



27. S. margaritalis W. V. — Fab. — erucalis Hilb. 9. 55. — Norfolk & Berks. 



28. S. elutalis HUb. 10. 62.— i7««;.— stramentalis Treil. 7- 76. 18. 



29. S. forficalis Linn.—Hiib. 9. 58. 



30. S. sericealis W. V.—Hiib. 9. 56.— Leeana Fab.— Don 10. 357. 4. 



31. S. hybridalis Hilb. 17. 114.— T. noctuella W. V. 



I have excluded the P. dentalis Hub., as I think from his 

 figure that it cannot belong to this genus ; and my specimen 

 o{ Py rails cilialis Hub. is nearly related to the Crambi. 



The plant is Cniais palustris (Marsh Thistle).
