‘““To repeat again: if we desire to get rid of the migratory 
species of locusts now infesting several counties in the state it 
is absolutely necessary to plow every inch of the cultivated 
ground throughout the invaded region in which eggs have been . 
laid.”’ 
: THE PELLUCID LOCUST. 
(Camnula pellucida Scudd. ) 
This locust belongs to a different sub-family of grasshoppers 
than the lesser migratory locust; in fact it is related to the 
North African and Asiatic species so well described in holy 
scripture. It is much more robust than either of the other two 
migratory species. Fig. 27 shows this species with wings ex- 
panded, and fig. 20, 7 and h, 
shows both the male and 
female insect, as well as the 
egg and egg-masses a, Dand c. 
The pellucid locust has a rather 
wide distribution, occurring in 
California, Utah, Wyoming, 
Colorado and other western 

states. Itoccurred in immense 
| swarms in California during 
f the years 1877, 1878, and 1879, 
leaving devastation in its wake.

that of the two other migratory species, as they do not raise to 
a very high elevation, nor do they fly so continuously. By a 
careful comparison of the illustrations it will be seen that this 
Species is quite different from the others illustrated, nor does 
it resemble any of our native species. 
The females of the pellucid locusts'commence to deposit their 
eggs about theend of July, usually at least fourteen days later 
than the other migratory locusts. Their method of doing so 
is entirely different. Asa general rule they select for this pur- 
pose pasture land, road sides, or, by preference, clearings from 
which the stumps have not yet been removed, although the 
land has already been used for crops. In such places large 
numbers of eggs are deposited in the sod.# Usually they are 
placed right upon the surface of the soil, where they are pro-
