The American cockroach (Periplaneta americana L.). - This is the largest of the house roaches, being from one and one-fourth to one and one-half inches long when adult. It is brown, darker than the German roach, and has a more or less definite yellow band around the margin of the pronotum.

It is a native of the warmer parts of this country but has spread north and is now abundant everywhere except in the most northerly states.
