CLASSIFICATION OF THE FOSSORIAL, PREDACEOUS AND 



PARASITIC WASPS, OR THE SUPERFAMILY 



VESPOIDEA. 



BY WILLIAM H. ASHMEAD, A. M., ASSISTANT CURATOR, DIVISION OF INSECTS, 



U. S. NATIONAL MUSEUM. 



(Paper No. 8. — Continued from p. 210.) 



Family XXX. — Masaridae. 



Prof. Westvvood and others confused these wasps with the Yespidae 

 and the Eumenidae, although Latreille had years previously established 

 his family Masarides. Henry de Saussure, in his " Etudes," treats them 

 as a tribe. They, however, represent a distinct family close to the 

 Eumenida', but easily separated from them and the Yespidae by the 

 wings not being folded longitudinally, by peculiarities of the antenrwe, 

 which are usually strongly clavate at tip; by the wholly different abdomen, 

 the venter being flatter; and by the much larger scutellum. 



Of the habits of the Masarides. nothing seems to be positively known. 

 Some years ago Dr. Dyar gave me specimens of Masarh vespoides, Cr , 

 bred from what I take to be the nest of an Odynerine, taken in Arizona.
