his orange grove, in Orange County. Fla. January 5, L899, Mr. J. P. 
Donnelly, of Mount Dora, Fla. , sent an adult of the species and stated 
that they were sucking- the juices of his oranges. The specimen sent 
had been attacked and killed by Euthyrhynchus Horidanus Linn.. 
which accompanied it. Injury to cabbage, coin, cotton, and pea- was 
reported by Mr. J. P. Cooksey, Pin Hock, Fla.. January 6, L892, and 
injury to peaches from the adult bugs by Mr. J. P. Lorenson, Salt 
Lake City, Utah, September 12, 1898. September 26, 1904, Doctor 
Chittenden observed the adults puncturing okra pods at Washington,

These insects were also frequently observed on cotton bolls, though 
no injury could be directly attributed to them. The former species 
was exceedingly destructive to various field crops — corn, sorghum, 
cow peas, etc. — in north Texas in 1903. 
SHARPSHOOTERS. 
Although the first species to be discussed below is the one commonly 
known as the ••sharpshooter" of cotton, we may well consider three 
others, nearly related and with very similar habits. All four specie- 
are found more or less on cotton, and would not be readily distin- 
guished by the average planter.

Life history. — The adults pass the winter in rubbish, leaves, etc.. 
near the food plants. On January 11. 1905, they were found feeding 
on yaupon (Ilex decidua), reported by Mr. Sanborn as one of their 
favorite food plants. On cold days they crawl down among the trash 
and leaves. They begin to leave their hibernating quarters late in 
March, our first record at College Station being March '24. 1904, but 
are not common until two weeks later. On April *>. 1904, adults were 
common along a small tributary near the Brazos River on hackberry 
(Oeltis mississippiensis) and cottonwood, and still more numerous on 
elm and willow. On April 14 they were exceedingly numerous on 
(dm and hackberry, the droppingof their exudation being very notice- 
able: but none were found copulating. At this time numerous jassid 
nymphs were found upon these tree's, but. as we were then unfamiliar 
with the nymph of t riqw tra and were unable to rear any of them, the 
species is uncertain. The occurrence at this time oi these nymphs, 
which if not the species under discussion, must certainly have been 
nearly related to it. indicates, in any event, the possibility o( oviposi- 
tion in early April, although this is certainly not common. Numerous 
observations were made each week, vet none were found mating until
