we have found the word looked for and been satisfied with the definition 

 given. As the author states in the preface, the work cannot, in the nature 

 of things, be regarded as perfect or complete, but it is as nearly so as one

 published the highest possible standard may be reached. 



The four plates at the end of the book will be found most useful. 

 They show the Structures of the External Body Wall of several typical 

 insects, those of the Head, Mouth, Thorax and Genitalia, the Venation 

 according to the Comstock system, and the Nomenclature of Colours.
