THE OLIVE 



113 



CYNIPS OLEyE. 



This insect has long antennae which are enlarged slightly near the 

 ends with fourteen or fifteen joints according to sex. The upper 

 wings have three small cubical cells at the base. The borer at base 

 of abdomen is placed between two blade shaped ajDpendages. The 

 female bores into the branches and deposits her eggs. The result- 

 ing larvae gnaws the bark, wood, and even the pith, digging little 

 winding tunnels. The buds on the branches attacked soon wither 

 away. 



This insect reaches its perfect cleveloj^ment about the beginning 

 of summer. The methods for its destruction should be the same as 

 for the Hylesinus oleiperda. 



PTEPOMALTJS QUADPUM. 



This insect has antennae like an elbow, having nine joints, the 

 first long and the last oval. The head is large and broad, the 

 abdomen of the female prolonged into a conical point. Wings 

 without radiating cells. Tarsi with first joint the longest. Borer 

 scarcely visible. Head a splendid bronze green. Upper wings 

 transparent, without sinews, and with two black spots in each near 

 the outer edge. The Antennae and feet black. Tarsi deep yellow. 

 Its habits are about the same as the insect just described. 



PRAYS OLEELLUS* 



{See Plate XIII.) 



This formidable enemy of the olive is known as the olive moth. 

 The egg is globular in form (Fig. 7), and its surface is composed 

 of minute tubercles. In color it is milky white, and is about a 

 hundredth of an inch in diameter. 



The larva (Fig. 8, 8a, 8b) has a long, soft body, with fourteen 

 rings, one cephalic, three thoracic, and ten abdominal. It has 

 three pairs of true feet in the thoracic rings, and five false pairs in 

 the third, fourth, fifth, sixth, and tenth abdominal rings.
