THE CANADIAN ENTOMOLOGIST. 



Although we have not been able to determine, as yet, either the 

 original locality from which this moth came, or the original food plant, it 

 is not improbable that this insect has but lately taken to the apple, and 

 that it existed and may now exist as an obscure insect feeding on some 

 wild and uncultivated plant. 



THE APPEARANCE AND DESCRIPTION OF THIS PEST. 



The egg is very small, being only 0.6 mm.* in length, and 0.35 mm. 

 in breadth, and is, therefore, apt to escape notice. It is of a uniform light 



yellow colour, oval in shape, with the surface thrown 

 into small shallow depressions and elevations, which 

 become larger and deeper at one end, in the centre 

 of which there is a protuberance or very short 

 peduncle. One of these eggs is shown in figure 8, 

 greatly enlarged. 



The larva is also very small when first hatched, 

 being less than i mm. in length. It is at first of a 

 light yellow colour, with the head shining black, and 

 the shield on the dorsal part of the first thoracic

coloured centre ; the three pairs of true legs are 

 brown, while the five pairs of pro-legs are of the same colour as the 

 body, and are borne by the sixth, seventh, eighth, ninth, and last seg- 

 ments. As the larvpe become a little larger, the above characters remain 

 the same except that the shield on the dorsal part of the first thoracic 

 segment soon becomes shining black like the head, and the general 

 colour of the body becomes more of a light greenish-yellow colour, 

 due largely to the transparency of the body allowing the intestine, which 

 is filled with green food, to show through somewhat. These characters
