I am under many obligations to those who have assisted me 
in making this paper more complete, either by lending speci- 
mens to Professor H. T. Fernald that I might use them for 
study, or by giving me counsel at times when such was needed, 
especially Dr. Guy C. Crampton, 5. A. Rohwer of the National 
Museum; E. T. Cresson, Jr.; and to Dr. H. Skinner for the 
privilege of study at the American Entomological Society at 
Philadelphia. JI wish to thank Mr. W. S. Regan who so kindly 
spent valuable time while studying at New York, Brooklyn, 
Philadelphia and Washington, in securing for me material to 
‘work upon. It was my good fortune to have studied a part of 
the time under Professor. Charles H. Fernald whose aid and 
assistance I greatly appreciate. 
To Doctor H:. T. Fernald I wish to express my gratitude 
for the many ways he has encouraged and guided me in my 
work and for the aid so willingly given at all times. 
COLLECTIONS. 
The work in this paper is based upon the collections of the 
National Museum together with the collections made by mem- 
bers of the Bureau of Entomology in Texas in connection with 
the Southern Field Crop investigations directed by W. D. Hun- 
ter; and the excellent collection at the American Entomological 
Society at Philadelphia. The American Museum at New 
York and the Brooklyn Museum at Brooklyn contain valuable 
material. Besides these, the collections at the Alabama Poly- 
technic Institute and the Rhode Island Agricultural College 
are worthy of mention. 
Norte.—Since finishing this paper the writer has seen an article on this group 
by Mr. N. Banks (New Scolioidea, Can. Ent., XLIV, p. 197, 1912). Although 
arriving too late for consideration in this paper, it does not appear probable that 
it would involve any changes in it.
