Stated. Also, insect boxes and the wings of butterflies have been damaged. 



Prof. Liversidge, in Sidney, reports the same year Z. saccharina as 

 very common in New South Wales. It does not do so much harm to 

 books, as it cannot well get in between the closely pressed leaves of a 

 book, but it injures loose papers, maps and labels ; the loose edges of 

 piles or bundles of letters suffer more than the central portion. Writing 

 paper, too, probably contains more attractive matter in the way of size. 

 The labels were written only 15 months ago, and some hundreds have 

 been rendered totally worthless. 



The same calamity is reported by Mr. H. Lucas, assistant in the 

 Museum of the Jardin des Plantes, in Paris. L. saccharifia destroys labels 

 of white paper, but the parts printed with oil and minium remain un- 

 touched. The labels on starched paper were very much injured, but only 

 the white parts. When leaving for the country in 1862, he put in a drawer 

 various articles of clothing, all starched, collars, cuffs and bonnets, and 

 returning after six weeks, he found numerous holes, round or oval, in a 

 bonnet, and Lepisma near by. On the labels of Polyps, Madrepores and 

 others in the Museum, the writing was in a great part destroyed. Dr. 

 Aube, in Paris, says that the black part of the backs of bound books was 

 nearly destroyed, probably by Lepisma. 



Mr. Samuel Henshaw, Assistant of the Society of Nat. Hist, in Boston, 

 enclosed purposely living Lepisma with soft paper, part of a newspaper, in 

 a glass jar, and ascertained that the insects had eaten large holes in the 

 paper. 



The well-known antiquary, Mr. Quaritch, in London, had complained, 

 1870, of the ravages done to books ; and Mr. Lewis, in London, after 

 careful examination, stated that by eating parts of the bindings the books 

 were caused to fall to pieces ; yet he considered it impossible for Lepisma 

 to bore holes in the books, which were probably made by Anobium. 

 Prof. Packard, in his Guide, reports of silk and silken tapestry eaten by 

 Lepisma, which also devour the paste, making holes in the leaves of books. 

 Also, Mr. Home, in London, alluded to the damages done to silk gar- 

 ments in India by Lepisma. The insect evidently attacks the silk on 

 account of the stiffening matter in it, but nevertheless makes holes in the 

 fabric. Finally, Mr. Adkin showed a species of Lepisma which damaged 

 account books kept in the iron safe of an office in London. 



After all these reliable facts, there is of course no doubt that Lepisma,
