tricts of California. It infests the wood (limbs and branches), 

 foliage, and fruit of deciduous trees, including the peach, apri- 

 cot, plum, almond, quince, and fig, and especially the apple, 

 pear, and olive. In some cases apples and pears were so 

 infested with this scale as to destroy their market value. The 

 acacia, willow, eucalyptus, locust, etc., are also its food plants. 



NATURAL HISTORY. 



Fig. 22 represents a portion of a brancli infested by Greedy 

 Scales ; at the left are two of the scales, 

 enlarged — colors, gray or yellowish, and 

 brown. 



The scale of the female is nearly circular, 

 or slightly oval ; yellowish in color when it 

 covers a living, mature insect, but is gener- 

 ally a light gray. Th(^ full-grown speci- 

 mens measure nearly one line in diameter, 

 and its form is more convex than the other 

 species of aspidiotus described in this work ; 

 the c^uvia^ is between the center and one 

 side, or edge, of the scale. Eggs, ovate — 

 color, yellow.

Larva (Fig. 23) — color, yellow; 



.-,,.,-., . length, one-eightieth of an inch;

/ * setre. 



Female full grown (Fig. 24) is circular in form — 



color, yellow, with clear or nearly transparent 



blotches. She deposits from thirty-five to eighty eggs. 



Male (perfect) insect, winged. (I have not been able to pro- 

 cure a perfect specimen.) There are probably two broods each 

 year, as I have found the eggs in May and August.
