Peckham—Revision of the Attidce of North America. 591 
This species is reported from New York, Pennsylvania, Mas¬ 
sachusetts, North Carolina, Georgia, Alabama, Florida, New 
Mexico, Iowa and Nebraska. 
Cyanaea might easily be confused with Sassacus Papenhoei, 
but the shape of the celphalothorax is different, being more 
narrowed behind in Papenhoei. It also lacks the white band 
on the cephalothorax found in that species and the metatarsi 
are not so light.

Cephalothorax rather high, longer than wide, growing wider 
from first row of eyes to middle of thoracic part. Cephalic part 
flat, or slightly inclined, thoracic falling very little at first, and 
then more steeply, especially in male. Eye-region occupying 
1-2 of cephalothorax, wider behind than in front, 1-3 wider than 
long. Front eyes in a straight row, middle twice as large as 
lateral. Second row nearer first than third. Third row not quite 
so wide as cephalothorax. Sternum, in type species, narrow 
in front, with coxae near together and labium as wide as long. 
We include barbipes (Eris barbipes P.), which Cambridge 
put into Ashtabula, in this genus although it does not entirely 
agree with the type. The cephalothorax is longer and less 
rounded, the spines are different, the coxae are widely separated, 
the labium is longer than wide, and the sternum is slightly trun¬ 
cated. 
The falces have a single tooth below in both species, and in the 
males they usually project obliquely forward, but while Papen¬ 
hoei has the fang very long, with a double curve, in barbipes it 
is of the ordinary shape, but stronger than usual.
