NOTES ON NEW AND RARE BRITISH LEPIDOPTERA. 141 



difficult}', through the assistance of that accomplished Lepi- 

 dopterist, Professor Zeller, who has pronounced the so-called 

 dilutella of our collections to be the true adornatella of 

 Treitschke (re-described by Zeller himself in the Isis) and 

 distinct from his suhornatellaj with which latter there cannot 

 be a shade of doubt the Manx Pem.pelia is specifically iden- 

 tical, for it corresponds exactly with continental types of 

 that species which Mr. Stainton some time ago received 

 direct from Prof. Zeller. 



The dilutella of Duponchel, (if this be the dilutella of 

 Hiibner also I know not,) which continental authors con- 

 sider to be the obductella of Fisher von R., has not yet been 

 detected in this country. 



The most satisfactory conclusions may be arrived at from 

 Zeller's papers on subomatella and adornatella in the Isis 

 for 1846, and as Mr. Stainton has been at pains to write out 

 translations of them for my special guidance, it will be best, 

 I think, to place them in their entirety before the readers of 

 " The Annual."

 Alis anterioribus laete brunneis, costa, fascia prope basim 

 strigisque albidis, priore angiilata, posteriore subar- 

 cuata, puncto gemino nigro albido-cincto, serie punc- 

 torum nigrorum marginali.

 Var. b. — Alis anterioribus dilute badiis, ceterum ut a. 

 This species, which Duponchel is disposed to consider as 

 a local variety of Ornatella, differs from that most certainly 

 as a distinct species, by the deep, much more brown-red 

 ground colour, by the completeness of the two transverse
