bottoms is in hay fields. East of Alturas, the Warner Range 
extends for a number of miles in Oregon and California, a north and 
south Great Basin range, east of which is Surprise Valley, a Basin 
plain with three sink lakes. The Warner Mountains in California 
culminate in Warren Peak, in elevation ninety-three hundred feet, 
some miles southeast of Alturas, while Cedar Peak, eighty-four 
hundred feet, is sixteen miles to the east of that town. With our 
limited time we decided to study Cedar Peak, and this rugged 
eminence, the upper slopes of which were very steep, composed of 
loose decomposed rock between jutting and chimney-like pinnacles 
of volcanic material, furnished us with a very hard day’s work, to 
which much heavy manzanita chaparral added its detaining hand. 
From the summit, to the west, Shasta, over eighty miles away, 
hung in the sky in a most uncanny manner, while to the east 
Surprise Valley yawned beneath; to the northwest beautiful Goo.se 
Lake extended away into the distance. On the summit we found the 
Rock Wren, while a bunch of Clark’s Crows showed the distinctly 
boreal character of the region. Just below the summit we took one 
of the prizes of the trip, a wonderfully colored flightless katydid, 
this specimen being unique in all our collections. 
From the Alturas region to the Tonopah district of Nevada is a 
far cry, but a desire to compare the latter region with Nevadan 
districts to the north, west and south, impelled us to visit it en route. 
The immediate Tonopah neighborhood was of considerable interest, 
giving us much desired information on certain species concerning 
which very little was known. At Millers, fourteen miles to the 
west, we found the more austral Nevadan element well indicated. 
Some of the species here taken were difficult to secure, and almost 
certain to escape the casual collector. One of these was a flightless, 
clumsy, yet most interesting katydid, and to study it, in 1919, we 
spent two days and two nights in locating and securing six speci¬ 
mens, the enabling clue being the finding of several dead specimens 
in one of the plants frequented by the species. 
After a brief stop at Berkeley and San Francisco, we resumed work 
at Coalinga, California, in the southwestern section of the great 
interior valley, an arid region bounded on the west by the yellow 
hills of the Diablo Range. The open floor of the valley, with its 
scanty cover of yellow sun-cured grass, held some desired species, 
while the friendly interest of several Roadrunners assured us we 
were reaching more southern climes.
