ENTOMOLOGY. 



A. B. — Many thanks: any information about the Coleoptera will be acceptable. We hope 

 soon to have a list of the rarer species taken in Suffolk. 



Mil. Twinn. — We are much obliged by your paper on the "Humming Bird Sphinx," but 

 as it relates to an insect very common in the South of England, and the habits of which 

 are well known to Entomologists, we do not think any good purpose would be attained by 

 its publication. 



%* All communications on Entomology intended for insertion in this department of "The 

 Naturalist," must be sent before the 15th. of the month to C. B. BBEE, Esq., Stowmarket, 

 Suffolk. 



Errata. — By an inadvertence we had not an opportunity of correcting the proof of the 

 "Notice" in last month's number, we are therefore under the necessity of requesting our 

 readers to make the following alterations in that article: — Pago 230, sixth line from bottom, 

 for "m determined" read "are determined." Page 231, sixth line from top, for " There are 

 tivo men," read "These are the men." — Ed.

 F. O. MORRIS, Nunburnholme Rectory, Hayton, York; — Books for Revieio
