those in tlie Museum of comparative zoology' referred to hy 
Scudder in his "Materials for a monograph of the Orthoptera of 
Xortli America," and all that remain of those in the Harris col- 
lection. Lastly, but of prime importance, I have had the privi- 
lege of studying all in Mr. Scudder's collection, among them the 
types of the species described by him, without an examination of 
which it would have been impracticable to prepare this pajDer. 
The results of my studies, both in the field and of cabinet 
specimens, are here presented. Briefly stated they are the reduc- 
tion of one so-called species {halteatum) to a synonym of anoth.er 
{bolli), th« addition of one new species (saxatile) to the New 
England fauna, and the detection of what I believe to be another 
undescribed species {oculatum) which has been taken in close 
proximity and will probably be found to occur in southern New 
England. 
I have added a table of comparisons, which will probably be 
helpful in determining specimens, and a few sketches of details of 
structure which it is hoped will assist in the comprehension of the 
specific differences presented by the New England species in the 
parts represented. 
Owing to the difficulties and consequent confusion connected 
with the correct identification of the various species of this genus, 
I have not given the synonymy and bibliography of the species 
but mei'ely of the specimens examined, whenever such notes 
seemed desirable. 
For the accommodation of others working on this family, and 
in the hope that future confusion and synonymy may be to some 
extent avoided, I have decided to send representative specimens 
of the three common New England species to collections in 
various parts of the country. This I am enabled to do by reason 
of the considerable number of specimens in hand. And I hope 
that this practice of obtaining a large number of types and dis- 
tributing them, or at least representative specimens, will be 
followed by other workers. Specimens will be sent to tlie 
following collections : — 
Museum of comparative zoology., Cambridge, Mass. 
Massacliusetts agricultural collego, Amherst, Mass. 
.\merican museum of natural history, New Yorlc, N. Y.
