fine hairs which give them a grayish appearance. The abdomen is 

 sahnon colored. The young are dark brown or black and covered with 

 many spines. 



Life History. — The eggs are deposited singly or a few at a place 

 among the egg masses of mealy* bugs, under the bodies of the black 

 scale or among other scale insects. The young begin feeding as soon as 

 they emerge upon the smaller hosts first. The numbers of the host are 

 so great that the actual good done is not so marked as in the cases of 

 many other predators. The adults move little except when annoyed. 



Distribution. — Throughout the entire State. This species was 

 imported by Albert Koebele, especially as an enemy of black scale 

 {Saissetia olem). 



Hosts. — The young feed upon the eggs of the black scale, mealy bugs, 

 hemispherical scale and other similar insects.

General Appearance. — The adult beetles are rather broadly-oval in 

 shape and about one eighth of an inch long. The color is bright 

 metallic black or bronze. The head and thorax are reddish brown 

 with a dark spot at the middle base of the latter. This species is very 

 often confused with Scymmis marginicolUs but may readily be distin- 

 guished from it by the lustrous bronze color. The larva; are light 

 brown in color with an elongated yellow spot on the middle of the back.
