the 4 last species, of which he has made two more genera, so 

 that the jjenus in his Catalogue is now distributed througli five 

 genera. 



As Treitschke first called the group Acidalia, and I am not 

 disposed to divide it into several genera, I must abandon the 

 name Ptychopoda employed in my Guide; and finding Mr. Ste- 

 phens's last arrangement the most correct, I shall follow it here, 

 making such additions and corrections as may be necessary. 



1. A. dilutata Haiv. — dilutaria Hub. 19, 100? — reversaria Treit., Bup. 



pi. 173. 3. July and August, skirts of woods and hedges, common. 

 A. fimbriolata and A. cinereata Ste. are probably varieties : the G. de- 

 coraria Hiih. referred to in Mr. Stephens's Catalogue, does not even belong 

 to this division, and I have never heard of its being taken in England. 



2. A. lividata Linn. — scutularia Hub. 14. 72. Beginning of June and 



July, hedges. 



3. A. bisetata Treit., Dtip. 173. 4. — trigeminata Haw. — scutularia Hub. 



14. 73. End of May and June, hedges and chalky places, Darent. 

 4.^A. ornataria Hiib. 14. 70. — Dup. 173. 1. — paludata Sam. June and 

 July, chalky places, Darent, &c. 



5. A. contiguaria Hiib. 20. 105.— b. July, Wrentham, Suffolk. June, 



walls, Norwich. — m. August, Dover, grassy places. 



6. A. incanata Linn. — immutaria Hiih. 20. 108. — Roesel, v. 1. Class iii. 



tab. 11. End of August, on Colt's-foot at Bartoii Cliff, Hants; 

 Beginning of September, on stones. Isle of Wight. 



7. A. immutata Linn. — sylvestraria Hub. 18. 97- — punctaria Dup. 177. 



3? July, marshy places, Norfolk and Whittlesea-mere. 



8. A. rubricaria? Hub. 21. 111. & 94. 487. Mr. J. Standish took one the 



beginning of August flying in the day in the North Foreland Mea- 

 dow, Dover. I doubt if it belong to this genus. 



9. A. ossearia Hiib. 19- 102. — subochreata Ste. var. End of June, hedges 



and woods, Darent, &c. 



10. A. marginepunctata Ste. Taken in the New Forest by J. C. Dale, Esq. 



11. A. virgularia Hub. I9. 104. var. — b. July, hedges, common. 



12. A. subsericeata i/aw. July, open places in Darent Wood. 



13. A. inornata Haw. Taken with the last. 



14. A. aversata Linn., Hub. 11. 56. The other figure referred to by Mr. 



Stephens is an Eupithecia ! — m. July ; b. September, common in 

 shady groves. 



15. A. remutata Linn. Found with the last. 



16. A. degeneraria Hiib. — Curt. B. E. pi. 384. fern. The only specimen I 



have seen of this rare moth I found on a block of stone at the back 

 of the Isle of Portland the 24th of last June in company with my 

 friend Mr. Dale. 



17. A. fuliginata Haiv. June, near London. 



18. A. fumata Curt, was taken on heaths near Schehallion and in the 



Black Wood, Loch Rannoch the 12th and 14th July 1825, by Mr. 

 Dale and myself, and was one of the 23 species of Lepidoptera that 

 were first discovered by us in Scotland in the course of a few weeks. 



19. A. lactata Haw. — sublactata Hatv. var. End of May, shady groves, 



common. The G. sericeata of Hiib. referred to by Mr. Stephens is 

 not a British insect. 



20. A. floslactata Haw. — remutaria Hiib. 18. 98. End of May ; b. June, 



shady groves. 



21. A. pallidaria Hiib. 18. 96. The only British specimen I have seen of 



this, I received from Kent. It is totally different to my A. fumata, 

 to which Mr. Stephens has referred it. 



The Plant is Rubus casms (Dew-berry). The fruit has 

 been represented in Plate 356.
