Reinarhs. — This species has been introduced into the United States 

 within recent years. So far as I am able to ascertain it is to be found 

 only in New Jersey and New York. The habit of this and the pre- 

 ceding species of feeding under bark of various trees is very conducive 

 to the spread of the insects. For this reason we should expect it to 

 become rather widespread in this country. 



The specimens from North Bergen, N. J., were reared from larvae 

 found in association with the mealybug, Pseudocoocus comstocki 

 (Kuw.). It was assumed that the larvae were predacious on the 

 mealybugs, but no conclusive evidence in support of this assumption 

 has been obtained. 



I have compared our American specimens carefully with a long 

 series from Europe and there is no doubt about their specific identity.
