NOTES ON SOME WESTERN ORTHOPTERA; WITH THE 
DESCRIPTION OF ONE NEW SPECIES.

During the summer of 1906 the writer spent three months on the 
Pacific coast in company with Dr. H. G. Dyar. The main object 
of the expedition was the collecting and breeding of mosquitoes, but 
as occasion permitted some collections were made in other orders, 
especially Orthoptera, to which the following notes pertain. 
On the way out to the coast a stop was made at El Paso, Texas, 
where on May 25 about an hour was spent just before dark collecting 
across the Rio Grande in Mexico, near Ciudad Juarez. The collect- 
ing here was quite productive, and it is to be regretted that more 
time could not have been spent at this point. The immediate locality 
collected over was a sandy desert region sparsely covered with Larrea, 
ete. In this shrub Bootettia argentatus was found in some numbers 
and on the bare ground 7rimerotropis vinculata and [Heliastus aridus 
were common. 
We spent May 30 collecting along the course of a creek at Sierra 
Madre, California. On June 1 we went to San Diego and the fol- 
lowing day a trip was made to Tia Juana in Lower California. The 
morning of June 3 was spent in collecting near San Diego, and we 
returned to Los Angeles in the evening. Orthoptera were few in 
this region, in fact all through southern California insect life was 
surprisingly scarce. 
On June 5 the writer proceeded to Indio and Cochella, where three 
days were spent collecting. This desert region is much below sea 
level and very hot, the thermometer registering considerably over 
100 degrees during the middle of the day even at that time of the 
year. 
From June 9 to June 12 was passed in the vicinity of Los Angeles, 
and on June 13 a steamer was taken at San Pedro for Santa Catalina 
Island, where the 14th was spent collecting back of Avalon. The 
ground there is hilly and rocky, vegetation scant, and insects, es- 
pecially Orthoptera, not abundant.
