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

 capture new insects, at least undescribed, for as yet \ ery little

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

 cellent Entomologist J. 1''. Stephens, Esq. F.L.S. whose ex- 

 tensive knowledge of the subject and the readiness \\\\.\\ which 

 he has always assisted me deserve my warmest acknowledge- 

 ment. To Mr. Sowerby also 1 am indebted for many per- 

 sonal favours.
