Pests and Grease. 



By F. H. WOLLEY DOD. 



I trust I may be excused for raking up such an old and 

 somewhat hackneyed subject as the treatment of cabinet pests 

 and grease, but there are, doubtless, many entomologists who, 

 like myself, are still unable to cope with them to their entire 

 satisfaction. Of all the acknowledged common enemies to a 

 collection of L,epidoptera, grease is the only one which has ever 

 been a serious nuisance to me amongst the boxes. I am not 

 sure that I have ever been troubled at all with mites on verdi- 

 gris nor with mould, except such as has appeared on speci- 

 mens whilst in the relaxing time. The larger insect pests 

 Dermestidae (?) and Tineidse have sometimes troubled me a 

 little, chiefly amongst papered specimens. One hairy-looking 

 wriggly creature, which has never told me his name nor even 

 made mention of his family, and which, like most insects in 

 the larval stage, appears to divide his time between eating and 

 changeing his skin, is an old enemy of mine who has a habit ot 

 boring an almost completely round hole through the paper, 

 and, visiting papered specimen after specimen, has sometimes 

 continued in his wickedness for \vivks without discovery.
