320 Annals Entomological Society of America [Vol. VIII, 
is accepted as Loew’s species. (An examination of Loew’s 
material disclosed the fact that he had 3 species—or at least 
there are now three—in his type series). 
The record on the Nebraska specimen, given above, is 
undoubtedly an error, the larve having fed in the bark of the 
tree on which the Pulvinaria were, and not on the insects. 
Neopachygaster orbitalis was reared from larve found in a 
decaying holly tree (/ex) at Lyndhurst, New Forest, England, 
by Dr. D. Sharp on several occasions. Wahlberg’s record 
“Hab. in ligno Populi caseo ad Gusum Ostrogothiz’’ has 
been supposed to indicate that he reared the species from poplar, 
but nothing definite is known on the point. Verrall suggests 
that the species may be found upon holly exclusively.
