BRAZILIAN ICHNEUMONIDZ AND BRACONID 
OBTAINED BY THE STANFORD EXPEDITION.* 
STANFORD EXPEDITION TO BRAZIL, 1911. 
J. C. BRANNER, Director. 
By CuHARLEs T. BRUES. 
All of the species considered in the present paper were 
obtained by an expedition undertaken by a number of natur- 
alists from Stanford University. The party was led by Prof. 
J. C. Branner, and during a sojourn of several months, they 
visited a number of regions where little or no entomological 
collecting had previously been done. Mr. William M. Mann 
accompanied the expedition as entomologist, and as might be 
expected, many of the Parasitic Hymenoptera obtained prove 
to be undescribed. 
I have not been able to deal with every species, for example, 
members of the genus Ophion, as it is quite impossible to recog- 
nize with certainty some of the forms described by Fabricius 
and other of the earlier writers. 
A number of genera are here recorded from South America 
for the first time, and it has been found necessary to propose 
new genera in several instances for the Brazilian forms.
