cases of destructive appearances ai;e to be fouud recorded. It often 
increases so as to cause local damage and is yearly more or less abundant 
throughout its range. In company with the Differential and Two-striped 
Locusts it frequently gives cause for alarm by devastating grass lands or 
growiug crops. In 1885 it was abundant, with atlanis, spretus, and local 
species, about Glendive and in other portions of eastern Montana. In 
August, 1888, it had, with Mvittatus, destroyed the oat crop about St. 
James, in Manitou County, Michigan. Such isolated reports as tbese 
come in nearly every year and only show that the species is not capable 
of concerted damage over any large area. 
Life-History and Habits. — These differ little from those of the fore- 
going species. The female has occasionally been noticed to lay four 
different egg masses. The period between hatching and maturity was 
observed at St. Louis to be about 70 days. The species was observed to 
become winged there about the last of August, and eggs were deposited 
about the first of October. It is sinale-brooded. 
THE CALIFORNIA DEVASTATING LOCUST. 
(Calojrieniis devastator Scudd.) 
Range of the Species. — Scudder records this species as found in 
California, Nevada, and even sparingly in Colorado. It is, however, 
essentially a Pacific coast species and is probably to be held accounta- 
ble for much of the damage attributed in this region to other species. 
Bruner also records it from the Upper Yellowstone Valley.
