“The arrangements we had to make with the proprietors of the stage line gave us a trip of five days from Beaver Canon to the mammoth Hot Springs for $35 apiece, there being three of us. But if we stopped over anywhere it was $10 extral it was also $10 extra to make the trip to Yellowstone Lake. But I am very glad we did not omit this, as it is by far the most delightful part of the Park.

The Great Salt Lake of Utah has been easily accessible for many years, and its shores have been visited by various entomologists; so that it seems strange that no one has hitherto published a comprehensive or even partial list of the insects occurring in that interesting locality. During the present summer, while on a short excursion to Utah with Mr. H. G. Hubbard, we had the opportunity of spending some time in the investiagation of the insect faune of the Lake.

It seems incredible that creatures as highly organized as the ticks and mites should be able to live for months and even years without food, and, in the case of some of the former, are capable of surviving even a prolonged immersion in a somewhat acrid fluid.

As an illustration of this remarkable vitality I wish to call attention to the case of two species that have come under my observation during the past year.

In the late publication of the Department of Agriculture on “Foresttree Imsects” three species are mentioned as affecting the trunk of Pyrus americana, viz: The round and flat-headed apple-tree borers and an unknown longicorn larva. I have recently found two additional species fully as injurious as those mentioned. These are Podosesia syringœ and Zeuzophora semifuneralis.
