 Nos. 1, 11, 13, 19, 20, and 21, are from the accurate figures in 

 Wood — the Caterpillars are from Hiibner — the rest of the insects are 

 from the cabinet of Mr. Bentley, for whose great liberality, in allow- 

 ing the whole of his specimens in succession to be removed, (notwith- 

 standing the risk to minute and fragile species) for the purpose of 

 more deliberate examination and delineation, we have to return cordiril 

 thanks, and express our great obligation ; as also for the information 

 and suggestion supplied by him. We have also to return thanks for the aid 

 we liave received in the prosecution of our laborious task from 

 Messrs. Stephens, Chant, E. and H. Douhleday ; as well as to other 

 gentlemen, whose names are recorded in our pages in conjunction with 

 the facts or species which they have communicated.
