insect which might happen to be damaging their plants; and, 

 secondly, that the student who should desire to know more of 

 this curious family might have enough details indicated to guide 

 him in his investigation. For the first purpose the figures have 

 been coloured as near to nature as possible : for the second a 

 few anatomical details have been introduced. The printing of 

 these plates has been executed by Mr. Potts, lithographer to 

 Mr. A. Willis, of Wanganui, and it is hoped that the reader 

 may be well satisfied with the care and trouble which have been 

 bestowed upon them. 



The author is sensible that this volume may contain 

 numerous imperfections ; but these will not, he trusts, be 

 attributed to culpable ignorance or carelessness.
