 (Fig. 207.) 



General Appearance.— The adults appear at first sight to be black 

 but upon closer examination it will be found that there are two quite 

 large reddish-brown spots upon the back as shown in Fig. 207. They 

 are elongate or oval in shape, scarcely one eighth 

 of an inch long and are exceedingly active. The 

 eggs are very small, oblong, yellow and laid 

 singly. The larva? have yellow bodies which are 

 entirely covered with long white cottony-like fila- 

 ments. The pupal stage is passed within the old 

 larval skin. 



Distribution. — The ladybird beetle was intro- 

 duced into California by Geo. Compere from the 

 Philippine Islands during the year 1910 and 

 liberated in the central and southern parts of the 

 State, where it has become established. 



Hosts. — The larva? and adults work primarily 

 upon the eggs and young of the citrus mealy bug {Pseudococcus citri) 

 and the long-tailed mealy bug {Pseudococcus longispinus).
