rosa from Blazer’s Mill (a mile below the Agency), elevation about 6200 
feet, down to the crossing of the stream at the half-way place between 
Tularosa and the Agency, elevation about 5200 feet. It thus occupies 
here a vertical range of about 1000 feet, in the upper edge of the Upper 
Sonoran , from about 5200 to 6200 feet elevation. The distance that it 
extends along the road down the stream is 8 miles. It occurs in very 
large thickly-growing patches, sometimes of several acres in extent. The 
plants attain a height, some of them, of 8 or 9 feet, and have immense 
woody stems. This gives an idea of their rank growth here. They are in the 
height of bloom about October 1st, but last for three or four weeks later 
than this date, and their flowers are especially visited by large numbers 
of very interesting diptera, particularly Tachinidae and Syrphidae. The 
best collecting of all, in the Diptera, was done on these flowers. Espe- 
cially prominent were such large-sized genera of Tachinidae as De- 
jeania , Jurinia , Saundersia, Echinomyia, etc. All of the details are 
given in the paper above referred to. Among the Syrphidae were many 
interesting forms also. Such of the Diptera taken on these flowers as 
have been determined up to the present time, are given; these include 
but little more than those taken on the first trip, while a mass of material 
remains that was taken on the second trip. The locality is the Tularosa 
valley below Blazer’s Mill, and the elevation from 5700 to 6200 feet, un- 
less otherwise stated:
