8 DESTRUCTIVE INSECTS OF VICTORIA: 



As there are a few otlier insects wliicli attack tlie 

 fruits herein mentioned, of which rehable specimens 

 coukl not be procm*ed, it is intended to descril^e them in 

 Appendices. 



I am glad here to acknowledge the great assistance 

 which I have derived from the perusal of such books as 

 Westwood's Classification of Insects, Buckton's British 

 Aphides, Kirby and Spence's Entomology, the valuable 

 books published by Miss Ormerod, Packard, Stainton, 

 Whitehead, and Walker, including the splendid reports 

 issued by Professor Riley, and other American friends, 

 and, coming nearer home, to the admirable work by Mr. 

 Maskell on the scale insects of New Zealand; the various 

 excellent publications issued by the late Mr. Crawford, of 

 Adelaide ; Mr. Oliff, of Sydney ; Professor McCoy, of Mel- 

 bourne ; Mr. Tryon, of Brisbane ; to say nothing of the 

 valuable journals, &c., published in Melbourne, as also in 

 the other colonies. 



To the many kind friends wdio have assisted me l)y 

 their advice, and have furnished valuable information, I 

 beg to return my sincere thanks ; and as at the present 

 stage it would perhaps be invidious to mention names, I 

 shall do myself the pleasure of an acknowledgment in 

 the concluding number of the iDook. 



The time has arrived when, if we are to fight insect 

 pests successfully, united action must be taken, and 

 knowledge gained by constant vigilance, and by useful 

 and carefully conducted experiments. Only thus can a 

 better knowledge be obtained of the relations of insects to 

 agriculture, viticulture, and horticulture.
