52 MISCELLANEOUS COTTON INSECTS. 
It will be seen that the eggs hatch in six or seven da} T s; but that 
the period of oviposition lasts for a number of weeks, so that the two 
broods overlap more or less. There seems abundant evidence that 
there are two and more probably three full broods. Concerning this 
matter Prof. E. D. Ball, one of the best authorities on the Jassidae, 
writes as follows: 
If adults go over winter they would surely not have second stage larvae by April 
14, as overwintering species usually have to feed long enough in the spring to develop 
their eggs, and* usually larvae are later in appearing than from overwintering eggs by 
about a month. The record of "sexes copulating May 20" would be about the 
record I should expect for an overwinter adult. 
However, as previous^ noted, the adults frequently come out and 
feed on warm days during the winter months, and as the season was 
early and the previous winter very open in 1904, it is entirely possi- 
ble that there may sometimes be an additional spring brood; but this 
is undoubtedly not true in the large majority of cases. 
These insects seem to be much more active in the spring than in the 
fall, but are decidedly more hardy in the fall. On October 11 it was 
observed that they did not move around much and were not easily 
disturbed. Early in the morning, in early summer, they will jump 
like a grasshopper when disturbed; but if the plant is slightly jarred 
in the middle of the day they fly with a distinct buzz. 
Frequently a large white spot of lime-like matter is found toward 
the tip of the wing of this species, often more or less rubbed off. 
Mr. Sanborn has observed the formation of this spot: 
It is transferred to the wing from the anus with the distal end of the metatibia. 
When exuded it is globular and resembles an egg, but is not pure white. With an 
adroit motion of the hind leg the insect secures the drop as it is drawn past the anus, 
and with a forward movement it is brought against the side of the wing to which it 
adheres. A similar spot is then placed in the same manner on the other w T ing. 
These spots occur on both sexes. 
Food plants.— In addition to those mentioned above, the following 
food plants have been observed: Wild grape (Vitis cinerea), Osage 
orange, Johnson grass, thornj^ amaranth {Amaranthus spinosus), 
cocklebur (Xanthium canadense), grape, banana, and apple. Riley 
and Chittenden record it as attacking asparagus in South Carolina. 
Supposed injury. — During August there is always considerable com- 
plaint that "sharpshooters" are injuring cotton by causing the squares 
and small bolls to flare and drop. Many of these complaints have been 
investigated. The writer has solicited reports of injury, with the offer 
to personally investigate thern, and has had extensive correspondence 
upon the matter with many planters, but no evidence of such injury 
being due to this insect has been secured. On the other hand, all 
manner of insects were sent us, many even considering the boll worm
