BASSBTTIA CORRUGIS (BasMtt). 



Holcaspis (?) corrugis Bxssett, Trans. Amer. lint. Soc, vol. 14. 1887, 

 p. 131. 

 From an unknown gall. Taken ovipositing in spring in buds of 

 Quercus prinoides. As the head is broader than thorax, massive, 

 the antennae not moniliform, the third segment longer than the 

 fourth, last not twice preceding, the second tergite with an inter- 

 rupted ring of hairs at base, pits of scutellum narrow, oblique, malar 

 space less than half eye, and ventral spine five times as long as broad, 

 the species is here transferred to Bassettia.

The three types in the United States National Museum and one

ANTISTROPHUS UGODESMIAE-PISUM (Walsh). 



Beutenmueller has very justly recognized that AsclepiadipkU^ 

 stephanotidis Ashmead is but another name for this species. By a

 family and not found wild in this country and certainly not escaped
