Destructive Appearances. — In our annual report for 1883 we gave 
a full historical account of the destructive appearance of this sr.ecies, 
and to this account those who are interested are referred. They have 
been reported as injurious in 1743, 1746, 1749, 1754, 1797 } 1798, 1816, 
1821, 1826, 1871, 1872, 1874, 1875, 1877, 1882, 1885, and 1889, in one and 
another locality in New England. The 1885 appearance was described 
in the report mentioned, and that of 1889 is treated in Insect Life, Yol. 
II, pp. 66-70. Mr. Brimer, in 1885, found the species numerous about 
Glendive, Montana, and in many places in the region of the Yellow- 
stone and Missouri Bivers it was twice as numerous as spretus. 
Life-historv A.ND Habits. — The followiug is from the report for 1885. 
In general life history it is in all respects similar to G. spretus. It 
will be unnecessary, therefore, to give here anything beyond the most 
salient facts. 
The eggs and the egg mass are so similar to those of G. spretus that 
there is no other difference than in the somewhat smaller size of either. 
They are laid just beneath the surface of the ground in precisely the 
same manner. Each female in the course of her life usually deposits 
two of these masses, though at St. Louis I have observed instances in 
which three and even four were placed by the same female. It is in the 
egg state that the insect passes the' winter and the young locusts hatch 
in the spring. The average period between hatching and maturity we 
found at St. Louis to be 80 days, or some 10 days longer than in the 
case of G. spretus and G. femur-rubrum, but in New Hampshire it is 
probably somewhat longer. 
In about one week after reaching full growth the insects pair, and 
soon thereafter commence ovipositing. There is undoubtedly but one 
annual generation in New England, whereas in Missouri we found uni- 
formly two. In the Herri mac Yalley the hatching period extends 
throughout May, and most of the individuals have become winged by 
the early part of July. Oviposition continues from the latter part of 
July till frost. Some of the earlier laid eggs hatch in autumn, so that 
there is the same tendency toward a second brood as we find in spretus, a 
tendency which is more marked during a warm, protracted autumn, and 
which is beneficial to the farmer, inasmuch as all these autumn-hatched 
individuals invariably perish during the winter. 
THE NON-MIGBATOBY BED-LEGGED LOCUST. 
(Galoptenus femur -rubrum Harr.) 
Bange of the Species. — This locust has a common range with the 
preceding species. It breeds from Florida to British America, but is more 
scarce in the eastern portion of its range while it becomes abundant in 
the Hississippi Yalley. G. femur-rubrum is also found with atlanis on 
the Bacific Slope.
