PKEFACE TO THE NINTH EDITION. 



THE reader is requested to correct certain errors as follows : 

 Pp. 69 and 616, Lepisma, with other Thysanura, is not neu- 

 ropterous. P. 346, the name of the common clothes-moth 

 should be changed from Tinea flavifrontella Linn, to Tinea 

 pelliolella Linn. P. 466, Pig. 433 represents the larva of 

 Ccenia dimidiata Fabr., according to Mr. 0. Lugger, who 

 has raised it. P. 611, Fig. 598 does not represent the eggs 

 of Corydalis cornutus, which have been correctly identified 

 and figured by Dr. Kiley. P. 655, for PEDIPALPI substitute 

 for the name of the order the word ARTHROGASTRA, of which 

 the Pedipalpi are a sub-order. P. 680, SpirostrepTion copei 

 should read Scoterpes copei. 



In the author's text-books on Zoology, and also in his 

 " Entomology for Beginners," he has adopted a new classi- 

 fication of insects, dividing them into sixteen orders. This 

 scheme will probably be introduced 'in the next edition of the 

 present work. 



Providence, July, 1888.
