 as far north as the 35° of latitude ; but it has not been found 

 by me in Alabama.

This is one of the most common species of Attus around Boston. It is 

 found at all seasons in thick tubes of white silk, under stones. None of my 

 specimens have the tufts of hairs on the head as distinct as in Hentz's fig- 

 ure. I do not know the male.
