Hosts.— The writer has collected the larva? of this species in large 

 numbers in the canyons of Ventura County, where they were feeding 

 upon a small native plant louse {Eichochaitophorus populifolii Essig). 

 Quayle reports it as feeding upon red and purple scale. It also preys 

 upon various species of mealy bugs doing effectual work upon the 

 citrus species {Pseudococcus citri).

 dish prothorax and head— the former having a black spot at the base m 

 the males and nearly all black at the base in the females. It is less than 

 one eighth of an inch long and distinguished from Lindorus lopanthcB 

 by its dull color, the latter being shiny.
