Habitat. — Washington County, Maryland. 



Described from two specimens in the collection of the Maryland 

 Experiment Station. The accession states that these two specimens were 

 reared August 2nd, 1898, from a larva on a peach twig infested with 

 Lecanium nigro-fasciatuin. The usual hosts of species oi Horn aloty his are 

 Coccinellidce, and it is safe to assume that the host in this case was the 

 larve of some lady-bird which was feeding on the Lecanium.
