and markings, except that the hind tibiae were of a light reddish color. 
All the specimens that I captured of this red-legged form are females, 
and Professor Eiley writes me that he is unable without the male to 
decide to what species they belong. I strongly suspect that they sim- 
ply constitute a color variety of Melanoplus devastator, since such varie- 
ties are known to occur among several of the species of this genus 
found east of the Eocky Mountains. These three forms, which, as 
above stated, probably belong to one and the same species, were the 
only spine-breasted locusts with long wings that I met with during my 
investigations. I also found two or three species of spine-breasted 
locusts with short wings, belonging to the genus Pezotettix; but these 
were mostly found in the dry pastures, and only in limited numbers. 
Among the spineless-breasted locusts, the species I met with the most 
often is the Eed- winged Locust {(Edipoda venusta Stal.); this I found 
in almost every locality visited, but never in large numbers. The next 
most abundant species, and one of the largest found in this State, is the 
Dissosteira spurcata of Scudder ; this is more local in its distribution 
than the preceding species, and is usually found in dry pasture lands, 
sometimes occurring in quite large numbers. The male of this species 
is much darker colored than the female, and has a curious habit of hov- 
ering in the air for several minutes at a distance of 16 or 18 inches above 
the female. 
The Pellucid-winged Locust (Camnula pellucida Scudd., of which 
(Edipoda atrox Scudd. is a synonym), which was reported as being very 
destructive during several successive years in the past in Sierra Valley, 
lying partly in Sierra and partly in Pimas counties, in the very heart 
of the Sierra Nevada Mountains, I met with at only one place; this 
was on an open hillside in Calaveras County, August 8, but they were 
not at all abundant, and I saw only about two dozen specimens in an 
hour's search. I dissected several of the females, and the ovaries con- 
tained nearly fully formed eggs. Several other species of spineless- 
breasted locusts were also met with, but these were so few in number 
that no further mention of them need be made at the present time. 
BREEDING GROUNDS OF THE DEVASTATING LOCUST. 
Up to the present time but little seems to be known concerning the 
early stages of the Devastating Locust. I have not been able to find 
any published notice stating that any observer had seen these locusts 
paired, or had observed the females laying their eggs, or had found the 
eggs of this species. During the present investigation I paid especial 
attention to this part of the subject. Although repeatedly sought for, 
I never found any of the young of this species in the more central portion 
of cultivated orchards and vineyards, nor in grain fields that had been 
plowed and. seeded less than a year previously. I also did not find 
them in thickly wooded land where there was an abundance of small 
trees and bushes, nor upon the tops or the steep sides of high hills,
