36 INJURIOUS AND BENEFICIAL INSECTS OF CALIFORNIA. 



Life History. — The life history of this species does not appear to 

 differ greatly from thai of the angular-winged katydid. The eggs of 

 this genus are usually inserted into the edges of the leaves, but Pro- 

 fessor Woodworth has reared the adults from the eggs laid as described 

 above. 



Nature of Work. — The katydids eat small holes in the rind of the 

 t*i ti i t when it is still green. As the fruit grows the injury enlarges. 

 This injury is often quite general and entails a considerable loss in 

 some districts. 



Distribution.— This species is quite widely distributed throughout 

 the State. 



Food Plants. — The katydids are quite general feeders and seldom 

 prove serious to any one crop. In some localities the foliage and fruit 

 of orange trees are attacked. The rind of the fruit while still young 

 is eaten and develops deep, ugly scars, rendering the fruit unfit for 

 market." 



THE MEXICAN KATYDID 



Scudderia mewicana (Saussure) 



( Phaneroptera mexicana Saussure) 



(Fig. 32) 



Description.— This species greatly resembles. the preceding one in 

 genera] appearance and size. The chief difference is in the length of 

 the hind femora, which almost extend to the tip of the wings. 



Life History. — The life history is not known. The eggs are prob- 

 ably inserted in the edges of the leaves. 



Nature of Work. — The work is the same as that of the angular- 

 winged katydid.

Distribution. — This species occurs throughout the State, but is 

 more common in the southern part. 



Food Plants. — This species lives upon the foliage of various plants, 

 hut often attacks the leaves and fruits of the orange trees, much as 

 does the preceding species.
