undivided shape distinguishing the species from the Tetraopinse, 
to which they are allied by the form of the thorax. The body is 
linear and setose. The antennse are filiform and longer than the 
body in both sexes ; the third joint is much elongated, and half 
as long again as the fourth, the remainder being filiform and 
slender to the apex. The pro- and meso-sterna are both very 
narrow. The legs are moderately elongated, and the tarsal 
claws have a large tooth at the base. 
I am indebted to Mr. Alexander Fry for pointing out the chief 
distinguishing characters of this genus.

The chief character which distinguishes this genus from 
Tetraopes (the chief American representative of the group Asta- 
theinse) is the form of the tooth of the claws. The tooth in 
Tetraopes is long and acute, running parallel to the claw itself, 
but much shorter; in Phcea it is very broad and short, adhering 
only to the base of the claw, as in the Callianse. The eyes, as 
in the rest of the Astatheinse, are completely divided. The body 
is more or less elongate and linear.
