Kinsey: The Genus Neuroterus 
5 
Mr. S. A. Rohwer and Mr. L. H. Weld, of the U.S. National 
Museum, have been liberal in loaning paratypes and in several 
instances in securing data for me from the National Museum 
collections, and have been very helpful in their advice on 
certain questions. Dr. Henry Skinner and Mr. E. T. Cresson 
Jr., of the Philadelphia Academy, have given me most valuable 
help in obtaining paratypes of the many Bassett species; 
without the opportunity to study these paratypes, this paper 
would have been so very incomplete as to have made publica- 
tion unwarranted at this time. 
The Indiana University authorities and the faculty of 
this Zoology Department have continued their support, offer- 
ing time, materials, and encouragement without which the 
work would have been long delayed. I have been loaned or 
given material of Neuroterus by Dr. Lutz and Mr. Mutchler 
of the American Museum, Dr. McCracken of Stanford Univer- 
sity, Dr. Anderson of the Missouri Botannic Gardens, Prof. 
Essig and Mr. C. T. Dodds of the University of California, 
Dr. Felt, State Entomologist of New York, Mr. Johnson of 
the Boston Society of Natural History, Prof. T. D. A. Cocker- 
ell of Boulder, Colorado, Dr. W. E. Britton, State Ento- 
mologist of Connecticut, Prof. A. Trotter of Portici, Italy, 
Dr. Charles Sajo of Hungary, Dr. Runar Forsius of Fred- 
ricksberg, Finland, and some others acknowledged in the 
proper connections. Mrs. I. T. Wilson and Miss F. D. Flemion 
have done the enormous amount of work necessary in the 
mounting and labelling of my material, most capably helping 
in an indispensable part of the study. Finally, Mrs. Kinsey 
has helped in the proof reading, and contributed the sort of 
encouragement and council which is of inestimable value. 
Enough help has been brought together to warrant the hope 
that this treatment may not be too incomplete a record of 
our present knowledge qf Neuroterus. 
In the comparative descriptions employed thruout this 
paper, in any instance only those characters are described 
which are of contrary quality to those of the related things. 
A taxonomic description is not a study in minute, external 
anatomy, and is most usable and easily comprehended when 
omitting all but essential items. Nevertheless a very com- 
plete description of any variety may be obtained by adding 
the descriptions of the species, subgenus, and genus to which 
it may belong.
