The similar appearance of Eulepia cribrum (pi. 56.) and of 

 the group now under consideration, has led Latreille and other 

 authors to connect the Bombycidae and Tineidse at this point; 

 but on comparing the essential generic characters I think no 

 affinity can be established: I shall therefore include the genera 

 of my Guide from 821 to 827, and perhaps 828 and 829 in 

 the family Lithosiidae. 



The names in my Guide of genera 1028 and 1029 must be 

 transposed, for M. Latreille gave T. evonymella^ padella and 

 echiella as types of Yponomeuta, and Mr. Haworth having 

 included both my genera in his group Erminea, this name 

 may be retained for my genus 1028, which is preferable to 

 giving it a new name. 



The following are British species, and the 5 or 6 first live 

 in society in a web in the larva state. 



1. Y. plumbella Fab. — Hiib. — Tin. 13. 86. — End of August, 



hedges, Kent. Baylam Pond and Enborne, July 

 12th, J. C. Dale, Esq. 



2. Y. padella Linji. — Hub. 13. 87. — Evonymella Z)o7Z. 1. 9. — 



rorella Hiib. 34. 234.? — End of July, hedges and 

 gardens. 



3. Y. Cagnatella Hiib. 58. 391 and 392. — rorea Haw.., a va- 



riety of Y. padella probably. 



4. Y. irrorella Hiib. 14. 93. — Found in Surrey, but rare. 



5. Y. Evonymella Linn. — Don. 10.355. 4. — Caterpillars feed 



on the Spindle Tree, Bird Cherry, &c. The moths 

 are found in June and August, in hedges and gardens. 



6. Y. dodecea Haw. 514. 6. — decemguttella Hiib. 44. 303. It 



has been taken at Coombe. The Caterpillars were 

 said to have been found in the young shoots of Scotch 

 Fir-trees. 



7. Y. funerella Hiib. 13. 85. — Goda, pi. 44. 5. — I have a spe- 



cimen of this rare moth from Mr. Plastead's cabinet, 

 and I took another at Fontainebleau 22nd July 1830. 

 Taken also at Clifton near Bristol, by Capt. Blomer. 



8. Y. pusiella Linn. — Cwt. Brit. Ent. pi. 1:12** fern. — Litho- 



spermella Hiib. 

 The specimens in the British Museum of this and the fol- 

 lowing species are stated to have been bred or taken at Dover. 

 The eggs, cocoon and larva in our Plate are copied from 

 Hiibner. 



9. Y. Echiella Hiib.— Curt. B. E. pi. 412*/m.— bipunctella 



Fab. 

 This species appears in summer, and the Caterpillar feeds 

 upon the Viper-grass [Echium vulgar e). 



The plant is Lithospermum officinale (Common Gromwell), 

 on which the larvae of Y. pusiella feed.
