112 THE OLIYE 



The perfect insect has a slender elongated body, head cyhndrical, 

 longer than wide, j^i'otrnding eyes, antennae nine jointed, upper 

 thorax almost hexagonal, wider than it is long^ abdomen wider in 

 the middle than at the base, and composed of segments posteriorly 

 rounded, and in the female ending in the ovary, w^iicli is nearly 

 horn shaped. Upper wings nearly reaching to abdominal extremi- 

 ties, fringed with long hair, reaching about two-fifths the way round 

 the body, under wings plain and shorter, the feet robust, the femora 

 swollen, the tibia small at the base and enlarged at the extremities, 

 the tarsi short and thick, double jointed and finished with two deli- 

 cate claws. General color a splendid black, the antennae yellow, 

 the upper wings a dirty white. The length of body nine hun- 

 dredths of an inch. 



The Trips exist in the clefts of the branches and among the buds; 

 and if there are manv of them, they will extend themselves to the 

 under-part of the leaves. They are agile and fly well. The female 

 dej^osits her eggs wherever she happens to be, and the larvae remain in 

 the same place. About a month is necessary for the different 

 changes to take place. In the spring and autumn they produce 

 several broods. At the beginning of winter, those that survive, 

 conceal themselves under the bark, or in its crevices and rest quietly 

 till the following spring. When the Trips are in great numbers 

 and invade many branches, the trees infested should be shaken, first 

 spreading a cloth beneath, to gather up the larvae, chrysalides^ and 

 winged specimens that may foil. If the branches have been long 

 infected it will be better to take them off* outright and burn them. 

 Spraying with kerosene in the autumn before these lice have 

 thoroughly secreted themselves under the bark, will probably answer 

 every purpose. 



The Apple, Greedy, and Red Bay Scale insects have all been 

 noticed on the olive in California, but so far as known do not seem 

 to have inflicted much iniurv on the trees, and are easily extermi- 

 nated by the application of the usual remedies.
