States. My personal collection, at Wellesley, Mass., numbers 
several thousand specimens, and is the largest, most nearly com- 
plete, and most representative, containing material from nearly 
all sections of the district, but it still lacks New England examples 
of several of the recorded species. 
Classification. 
The insects generally referred to the order Orthoptera are the 
Earwigs, Cockroaches, Praying Mantids, Walking-sticks, true 
Locusts, Grasshoppers, and Crickets. These are sometimes 
classified in two orders, the Dermaptera or Euplexoptera, con- 
taining the Forficulidae or Earwigs, and the Orthoptera genuina, 
including the remaining six families under the names of Blattidae, 
Mantidae, Phasmidae, Acrididae, Locustidae, and Gryllidae. 
This is the classification, sequence, and terminology used in 
Comstock's "Manual of Entomology" and many other works. It 
is the sequence proposed by Brunner von Wattenwyl in his 
"Revision du Systeme des Orthopteres" (1893), followed by 
Scudder in his "Guide to the Genera and Classification of the 
North American Orthoptera" (1897), and is probably the most 
familiar to entomologists in general. 
The six so-called families of Orthoptera vary greatly in degree 
of relationship to each other, a condition which is not expressed 
by this classification. The Long-horned Grasshoppers and the 
Crickets are evidently closely related, and with the Locusts, 
which differ more widely from them, are conveniently and 
appropriately united in a group called the Saltatoria or jumping 
Orthoptera. The remaining three families, or non-saltatorial 
Orthoptera, differ much from the Saltatoria and from each other. 
The modern ideas regarding the relationship and proper classi- 
fication of these insects, as represented by the views of Hand- 
lirsch,^ which were based on palaeontology, embryology, and 
probable lines of descent, have been embodied to a large extent 
in a classification recently published by Brues and Melander.^ In
