Prosopea americana, Bigot, Ann. Soc. Ent. Fr. 1888, p. 260 - 
Prospherysa contigua, v. d. Wulp, antea, p. 120 (1890) *. 
I have seen a typical specimen of Bigot’s species and find that it is identical with 
my P. contigua. The correction in the synonymy has already been noted by me 
(anted, p. 210). 
ADMONTIA (to follow the genus Polygaster, p. 139). 
Admontia, Brauer and v. Bergenstamm, Denkschr. Akad. Wissensch. Wien, lvi. p. 104, t. 5. fig. 92 
(1889). 
The characters of Admontia are shortly but precisely described by the authors (J. ¢.). 
Females belonging to it are easily recognizable by the long and dilated front tarsi. The 
vibrisse are inserted just at the oral margin. The abdomen is elliptical, its basal 
segment at least as long as the following. The genus was founded on an Austrian 
insect, A. podomyia, Br. & v. B., and it also includes Degeeria blanda, Meig., and an 
undescribed new species from North America, A. americana, Br. & v. B. In the 
Mexican collection before me there is a form which seems to be closely allied to 
A. podomyia, though differing in some points of detail. 
In the analytical table (anted, pp. 41-44) the genus must be inserted as follows :—
