 not only meet with the species enumerated, but are likely to 

 capttu'e new insects, at least undcscribed, for as yet very little 

 is known of the Entomology of Britain. 



1 cannot omit returning my thanks to that acute and ex- 

 cellent Entomologist J. V. Stephens, Esq. F.L.S. whose ex- 

 tensive knowledge of the subject and the readiness vaih. which 

 he has always assisted me deserve my wannest acknowledge- 

 ment. To Mr. Sowerby also I am indebted for many per- 

 sonal favours.
