process of development, the last one occurring from June 25 to July 1. 
The mating season begins in from fifteen to twenty days after maturity, 
and in as many more the oviposition season begins. 
From the local distribution of this locust, as well as its large size, 
conspicuous coloring, and lubberly movements, no trouble is experi- 
enced in destroying it. The bran arsenic mash had been used upon 
this locust with good effect. Locating the eggs and exposing them by 
winter tillage is the most practical remedy. In very local outbreaks 
the net has been used to collect both nymphs and adults. A species 
of Sarcophagide has been found a common parasite of this grasshopper. 
Dissosteira carolina.—The Carolina locust eggs resemble very much 
in size and form those of the Schistocerca obscura after the coloring 
from the latter has been removed by alcohol. (This coloring of the 
eggs of obscura resembles in its reactions the color extract from the 
petals of red roses.) The eggs are laid in, the same areas as d/ffer- 
entialis and obscura. The preferred food of the voung we were unable 
to determine, and hence were unsuccessful in the effort 
to determine the life history of this locust. Grasshop- 
pers of all species are difficult to rear in cages, and this 
one we found no exception. The young would con- 
gregate upon the window side of the cage, and would 
there remain until starved to death. Cockle-burs, which 
were readily eaten by other species, were only occasion- 
ally nibbled. This locust did not appear in destructive 
numbers and is given consideration only because the 
egos and young are frequently confounded with those 
of the differential. From field observations the period 
of development of the Carolina locust is about equal to 
that of the differential, though mating and egg-laying 
is later.

Chortophaga vwiridifasciata.—This species is widely — Diéctyophorusrectic- 
distributed through the South, and though it appears in a ACS 
the Mississippi Delta in unusual numbers for this species, the damage 
done was not appreciable. It is here considered for two reasons: First, 
the young appear early in the spring and have been frequently mis- 
taken by planters for the differential. The young of the first brood 
appears as early as the middle and lastof March. It is double brooded, 
and receives a second consideration because the eggs act as food for 
differential egg parasites which-appear earlier than August 15 and 
September 1. “The first brood matures about May 15 and the last from 
October 1 to 18. As hibernation is passed in the ege condition, fall 
and early winter cultivation will prove destructive to the eggs. 
Melanoplus atlanis and Chloéaltis viridis were also found upon Da- 
homy, but not in sufficient numbers to warrant any alarm. Specimens 
of atlanis were received from the alfalfa sections of the Red River
