ONE PLATE 
In a: recent sending by Prof. Charles F. Baker of parasitic 
Cynipide from the Oriental. Region several new species were 
recognized as belonging to the Liopterinz and are here described. 
The first and third specimens of each sex have been retained 
for the United States National Museum collection and the second 
and fourth paratypes returned to Professor Baker. 
The subfamily Liopterinz as here treated includes both Dalla- 
. torrella Kieffer, a genus which has been proposed‘ and made a 
separate subfamily since the publication of the last monograph 
on the Cynipide,? and the closely related genus Mesocynips Cam- 
eron, which the Tierreich placed provisionally in the Cynipine. | 
It is distinguished from the Oberthiirelline, known only from 
Africa, by the lack of a tooth on the hind femur and the absence 
of a spine on scutellum; but, like that subfamily, the Liopterinz 
has the abdomen attached high on the propodeum instead of 
between the hind coxe; has the first abdominal segment (petiole) 
plainly visible and longitudinally ridged; and has the fourth or 
fifth tergite (the third only in Xenocynips) largest when seen 
in side view with usually two, and often three, short tergites 
behind the petiole preceding this big segment, and these may 
or may not be tongue-shaped. Both subfamilies have a some- 
what similar habitus, being relatively large, stout species with 
the mesoscutum coarsely and usually transversely sculptured. 
Two new genera have been added to the Oberthiirelline since the 
Tierreich monograph, and a key to the genera compiled from 
the literature is here included for that subfamily also,
