Our members of this genus are slender, 

 blat'k species, clothed with gray pubescence. 

 They resenible small Sapprdas, but have the 

 front short and subconvex instead of flat and 

 quadrate, and the tarsal claws cleft. Their 

 habits are, moreover, different, as they do not 

 breed in wood, but in the stems of herbs or 

 weeds. One of the five known species has 

 been taken in the State, while two others may 

 occur.
