MISCELLANEOUS COTTON INSECTS. 
extend the entire length of the body; these stripes are often narrowly interrupted on 
a line with the antenme. Another pair of dark stripes originate behind the eyes, 
and extend along the margin to the wing pads, where they divide and continue 
slightly obliquely to the margin of the latter, appearing again as single stripes on the 
abdomen. A transverse band runs in from the antennal sockets on each side. 
Front with five brown stripes, the median and lateral ones narrow and definite, the ■ 
intermediate ones which arise on the vertex are broad and interrupted by light arcs. 
Legs pale. 
The species is entire!}- harmless to cotton, and, so far as we have 
observed, and as may be judged from the fact that no records of injury 
by it have been published, it does not damage any cultivated crops.

The life history of this sharpshooter also seems to closely resemble 
those of the preceding species. The adults emerge from hibernation 
late in March, our first record being on the 22d. At this season and 
throughout the summer they 
are particularly fond of redbud 
( ( '< rcis canadensis) and are also 
common on elm. The first eggs 
were laid in confinement on 
cotton at Terrell May 5, and 
the first observation on adults 
mating in the Held was made 
on May 9. Three more lots of 
eggs were laid May 11, the de- 
position being much like that 
of Q. lateralis. These eggs 
hatched in eight and ten days. 
Those which hatched the 13th 
molted on the 26th and again 
on June 10. On June 30 all 
were dead, the wing pads just appearing on the larger ones. On 
July 2 Mr. Lewis observed in the cotton field numbers of this species, 
which, judging from their fresh, bright colors, had evidently just 
become mature. A few were copulating. Eggs were laid July 1 by 
females confined on cotton. The eggs were laid, as a rule, on the 
under side of the leaves, the single exception being laid on the out- 
side of the involucre, but not on the square. In the cage they were 
observed feeding on the leaves and stems of cotton, but never were 
seen resting on the squares. These eggs hatched July 10 and all the 
nymphs were dead by the 15th. By August 15 nymphs were found 
in the field with wing pads forming. On September 5 three adults 
were inclosed over a cotton limb, and on the 12th young nymphs were
