NOTICE. 



All letters, desiring information respecting noxious or other insects, shouli] 

 be accompanied by specimens, the more in number tlie better. Such speci- 

 mens should always be packed along with a little cotton, wool, or some such 

 substance, in any little paste-board box that is of convenient size, and never 

 encloted loose in the tetter. Botanists like their specimens pressed as flat as a 

 paucAke, but entomologists do not. Whenever possible, larvie (i. e. grubs, 

 caterpillars, maggots, etc.) should be packed alive, in some tight tin 

 box— the tighter the better— along with a supply of their appropriate food 

 snllificnt to last them on their journey ; otlierwi=e they generally die on the 

 roail and shrivel up to nothing. Along with the specimens send as full an 

 aci-uunt as possible of tlie habits of the insect, respecting which you desire 

 information ; for example, what plant or plants it infests ; whether it destroys 



you; what amount of damage it has done, etc. Such particulars are oflcn 

 not ouly of high scientific interest, but of great practical importance.
