INSECTS INJURIOUS TO THE ORANGE. 



383 



Fia. 393. 



No. 243. The Orange Leaf-notcher. 

 Artipus floridanus Horn. 



This is a beetle which is represented magnified in Fig. 393, 

 the line below it indicating the natural size. It eats jagged 

 notches in the leaves of the 

 orange, as shown in the figure, 

 disfiguring and injuring the 

 foliage. It is about a quarter 

 of an inch long, of a pale 

 greenish-blue or copper color, 

 and densely clothed with 

 white scales. The thorax is 

 unevenly dotted, and there 

 are on the wing-cases ten 

 longitudinal lines of dots of 

 varying sizes, divided by 

 slight ridges. The under side of the body and legs is also 

 scaly and hairy. 



In some localities in Florida these beetles are said to be 

 very abundant. As they readily drop when the trees are jarred, 

 they may be easily collected on sheets spread under the trees. 



Ho. 244. The Angular-winged Katydid. 



Microcentrum retinervis Burm. 



There is, perhaps, no insect of large size so destructive to 

 the foliage of the orange as this. It is a large green katydid, 

 and one of the commonest insects in the South. 



During the daytime it is seldom seen, as it is then hidden 

 among the thick foliage of trees and shrubs, but towards 

 dusk it leaves its hiding-places and makes the air resonant 

 with its music, which is produced by rubbing the wings 

 against the thighs. The eggs are deposited in abundance 

 upon both twigs and leaves, as shown in Fig. 394 at 1 a and 

 2 6, overlapping each other. They are of a long, oval form,
