side; the body nearly white, semi-transparent, and thickly cov- 

 ered with transverse rows of white spines." As its age increases it 

 assumes a close resemblance to the color of the leaf on which it 

 feeds. When full grown it leaves the bush, enters the ground and 

 constructs a little oval earthy cocoon mixed with silky and glu- 

 tinous matter, from which the fly emerges the following spring. 



Remedies. Spraying or dusting with hellebore proves an effi- 

 cient remedy. 



THE LESS PROMINENT INSECTS 



While the preceding list aims to include all species 

 which are sufficiently injurious to possess real eco- 

 nomic importance, it is obvious that no strict dividing 

 line can be drawn. In some cases insects included in 

 the following list have done much more injury than 

 many of those already mentioned. Much depends upon 

 local conditions and environment. If special condi- 

 tions favor an unusual development of any particular 

 species, the food supply of its parasites is thus in- 

 creased, thereby inducing an increase of the parasites, 

 and enabling them to reduce the species to normal 

 conditions. Thus nature's balance-wheel prevents the 

 undue increase of any class of her children and con- 

 sequent destruction by them. 



To all having access to entomological literature, the 

 references given here will be of aid in quickly ob- 

 taining information upon any of these species which 

 may chance to manifest unusual development and con- 

 sequent injury. Many of those mentioned can never 

 prove injurious, and to know this fact may at times 

 be even more welcome than to find methods of com- 

 bating them as foes.
