Ploiaria texana n. sp. 
A specimen from College Station, Texas, Sept., is in general very similar to the 
described species, P. carolina, but is a little larger. It differs in having six long

to the posterior part of head; the prothorax is longer, nearly twice as long as head, 
and also coxa I is longer than in P. carolina.
