distance from camp. In habit they closely imitate Pez. dodgei and Pez. 
obesa. One peculiarity of all the Acrididae of these mountain regions 
apjiears to be the great variability in coloration among different indi- 
viduals of the same species. Just what the cause of this phenomenon 
is I was unable to learn, but that there is cause for such variations 
there can be no doubt. 
Other orders of insects are not very numerous here, save, perhaps, 
Diptera and Heteroptera, and these are only numerous in individuals — 
the species being comparatively few. Of Diptera we noticed a few and 
collected such as may feed upon the eggs of locusts. Of Homopterous 
insects, and also those belonging to Xeuroptera, we saw bnt very few; 
of these, however, we collected what we well could. 
During our stay in these foot-hills we made many excursions into the 
surrounding country and mountains, each time finding something new 
or of interest. These trips were generally but of a single daj's dura- 
tion, as we were without horses and were obliged to return to camp at 
night. It was by means of these trips that we visited quite an exten- 
sive area of country, the surface of which is much varied. We there- 
fore, without much doubt, must have obtained a fair representation of 
the most common forms of the insect fauna of this region. 
It may appear incredible that there were so few species of Lepidoptera 
where so many and such beautiful flowers grow, but such is the fact. 
During the month that we spent collecting here we could not have seen 
more than seventy-five or one hundred butterflies and moths, and these 
all belonged to less than a dozen species. 
Having remained at this locality a month, we now started for Mc- 
Leod with our boat. The start was made from the mouth of Pincher 
Creek, going by river about 75 miles. After an exciting run over nu- 
merous rapids and shoals we reached our destination just after sun- 
set of the same day. After lying over for three days in order to lay 
in a supply of provisions and other necessary articles for our down- 
river trip, we pulled out on the afternoon of the 4th day of September. 
This undertaking was one which very many advised us not to try, as they 
claimed that the river over a great portion of its course was unexplored 
and might prove to be treacherous. However we thought we would 
run the risk. 
When we left McLeod our intention was to run as far down as the 
first settlement, or the first place where we could obtain transportation 
across country to the Assiniboine or Qu'appelle River, it being our in- 
tention, if possible, to make a portage and reach Winnepeg by these 
rivers in our boat. The first opportunity, however, came much sooner 
than we had anticipated, and much more to our desire, as it gave us an 
opportunity of visiting the country lying in the vicinity of Fort Walsh, 
as well as that to the eastward, where the great swarms of locusts of 
1875 and 1876 were bred. 
Before recording the occurrences of this trip, perhaps it would be
