4 APPLE. 



But with these, as with other occasional infestations of large and 

 handsome caterpillars, sometimes of rare species, and usually not very 

 numerous, it would often be the best way towards getting rid of them 

 to let some neighbouring collector of entomological specimens know of 

 their presence. In some instances their rarity would make permission 

 to clear them an acceptable boon to the scientilic entomologist ; in 

 others they would be a welcome addition to the stock of the professional 

 naturalist ; and during the last few years, when such rare attacks as 

 those of the Alder Clearwing Moth, or the great Lappet Moth, have 

 required extermination for obvious economic reasons, it has been so 

 urgently mentioned to me by entomological friends that they regretted 

 not to have been told of the chance of securing specimens, that I just 

 allude to their wishes as often helping to a serviceable remedial 

 measure.
