(i.e., Martin Falls) (as "Oedipoda phoenicoptera") and by Lieut.-Col.<br />

Hawkins from "Vancouver's Island" (as "0. rugosa"); Chorthippus<br />

curtipennis curtipennis (Harris) from "Hudson's Bay" (Martin Falls)<br />

collected by Barnston, and from Newfoundland, presented by a Pr<strong>of</strong>.<br />

Shephard; and Tetrix subulata (Linnaeus) (as "Tettix granulata") and<br />

T. ornata (Say) from "Hudson's Bay" (= Martin Falls).<br />

One <strong>of</strong> the pioneer entomologists <strong>of</strong> <strong>Canada</strong> was William Couper, who<br />

came to <strong>Canada</strong> from England in 1842, and who first collected Canadian<br />

insects <strong>of</strong> "all orders," no later than 1843 (Baillie 1929), but if any orthopteroids<br />

were among them (and there probably were), there is no way <strong>of</strong> telling<br />

Review <strong>of</strong> literature after 1850<br />

Locust and grasshopper outbreaks<br />

Since the trials and tribulations <strong>of</strong> 1818-1821, the settlers in the<br />

Red River valley <strong>of</strong> what is now Manitoba had no serious locust problem<br />

for many years, although they had other troubles. The Canadian West had,<br />

nevertheless, by no means seen the last <strong>of</strong> the Rocky Mountain locust and<br />

other major grasshopper pests, and Seamans (1956) notes, with some<br />

inaccuracy, most <strong>of</strong> the "locust" and "grasshopper" years from 1818 until<br />

1951. The first signs <strong>of</strong> serious trouble ahead seem to have been in 1855,<br />

when, as reported by Taylor (1859), severe outbreaks occurred in Oregon<br />

and Washington, the "entire territories" being covered by grasshoppers.<br />

There were also, according to Taylor (op. cit.), swarms in Minnesota that<br />

year-although this has been denied by Whitman (in Packard 1877)-and<br />

again in 1856 (Walsh 1866, quoting O. H. Kelley in Country Gentleman;<br />

Scudder 1872; Riley 1875, 1877b; Packard 1877, 1878; Lugger 1898). In 1857,<br />

the swarms became more numerous in various parts <strong>of</strong> the northwestern<br />

United States, including Minnesota (references as aforementioned), and many<br />

entered Manitoba. Riegert (1980) quotes earlier authors who described swarms<br />

in the Pembina River district. There was not much serious crop loss as a result<br />

<strong>of</strong> the visitations because the swarms arrived too late in the year (Scudder<br />

1872, with reference to a letter from the Honourable Donald Gunn;<br />

G. M. Dawson 1875b, cL Mitchener 1954b). Nevertheless, they deposited<br />

vast numbers <strong>of</strong> eggs that gave rise to abundant progeny in the following<br />

year, 1858 (Hind 1859:40,43; Gunn 1878). Hind (1859:44) gives a graphic<br />

account <strong>of</strong> a devastating flight <strong>of</strong> Melanoplus spretus to the west <strong>of</strong> what<br />

is now Souris, Man., on 2 July 1858. He also refers to other occurrences<br />

<strong>of</strong> locusts in Saskatchewan, and records observations on phenology.<br />

The seriousness <strong>of</strong> the locust plague <strong>of</strong> 1858 is stressed by many later<br />

authors. For the following few years, however, locusts were not prevalent<br />

until they appeared in Dakota territory in 1863 (Whitman, in Packard 1877)<br />

and Minnesota (Lugger 1898). They reappeared in force in 1864 and 1865,<br />

causing (according to some authors) widespread damage, particularly in the<br />

former year. Morton (1938), following Hargrave (1871), notes that the 1864<br />

swarms <strong>of</strong> grasshoppers had been preceded by "a severe drought, such as<br />
