THE OLIVE 111 



has the aspect of a tortoise shell, and is of a dark chestnut color, 

 very convex, with the ridge in the middle of the back and the two 

 lateral ones very distinct. As soon as the larva hatches, it leaves 

 its covering and the mother dies. The habits of this insect and the 

 methods for its destruction are the same as given for the Coccus 

 oleae. 



CTSTICOCCUS POLLINII. 



On the branches that are somewhat languid where dried berries 

 and leaves are adherent, can be found in the forks, and at the stem 

 of the leaves, small excrescences, like a grain of corn, the color of 

 the dry wood. On opening one, an outside shell is seen, and in 

 this is a soft heart shaped body or sack which is orange color and 

 enveloping as many as thirty eggs. In April the egg has the germ 

 well developed, and in May the larva appears. It is oblong-ovoid, 

 and has the antennae and feet shorter and more robust than the 

 Coccus oleae just described. The antennae are six jointed and 

 terminating in a group of bristly hair. The femora are very large 

 and on the last abdominal ring there are three short appendages, 

 each terminating in a short bristle. The ultimate transformation of 

 this insect has never been ascertained. The damage done by it 

 however is identical with that of the Coccus oleae, and the proper 

 method of destroying it is to cut off and burn the infected branches. 



TRIPS OLEAE. 



This insect is also called the olive louse. The damage caused by 

 it is very similar to that previously described. 



The larva is soft, oblong, and narrow behind, orange colored, 

 antennae whitish, feet black. The head is square in front, curving 

 in at the top, the eyes protruding, and placed midway the length 

 of the head; antennae short and thick, rings of the thorax large. 

 The abdomen has eight rings which are fringed on the sides with 

 stiff hair. Feet and femora robust, tibia as long as the femora, tarsi 

 short and thick, and like the tibia, terminating in short fine bristles.
