INSECTS INJURIOUS TO THE APPLE. 



injury to fruit-trees. 



It is represented in Fig. 105 in tlie act of 

 devouring the buds 

 Fig. 105. on a twig. It is of 



a light yellowish- 

 gray color, varie- 

 gated with dull 

 green, with a dark 

 line down the back, 

 and fainter lines 

 along the sides; the 

 spiracles, or breath- 

 ing-pores, are black. ' 

 When full grown,, it 

 is nearly an inch and a half long, when it enters the earth, and 

 there changes to a brown chrysalis. The moth (Fig. 105) has 

 the fore wings of a light bluish gray, with darker markings, 

 and the hind wings pearly white. The length of the body is 

 about seven-tenths of an inch, and the wings measure, when 

 spread, nearly an inch and a half across. 



The W-marked Cut-worm, Agrotis clcmclestina (Harris) 

 (Fig. 106), has also been found feeding on apple-buds, al- 

 though it more frequently attacks low 

 bushes, such as currants ; also succulent 

 plants, such as young corn, cabbages, 

 etc. The moth of this species (Fig. 

 107) has the fore wings of a rather dark 

 ash-gray color, with the deeper lines and 

 wavy bands but faintly traced. The hind wings are dull 

 white, with a tinge of brown, becoming darker towards the 

 hinder edge. The chrysalis is of the usual brown color, and 

 is formed in a cell under the earth, as in the other species 

 referred to. 



The family of cut-worms is a large one, and embraces 

 many other destructive species, but none of them, except 

 those above mentioned, are known to have the habit of 

 climbing trees. . Some of the other injurious species will be
