Calocoris rapidus. — This Capsid is very common upon cotton plants, 
and is usually found between the involucres and bolls. Its damage is 
done by puncturing the bolls with its beak. This leaves a small, round 
black dot at the point of the puncture, and this is the mark so often 
attributed to the moth of the Boll Worm. The injury nearly always 
has the effect of causing the boll to " flare" and drop, or if not, then 
the tuft of cotton in that section of the boll becomes stained. Largus 
cinctus proceeds in the same manner as Calocoris rapidus, leaving the 
characteristic puncture upon the fruit. 
Homalodisca coaguJata. — This leaf-hopper can be found quite common 
upon cotton plants from the 1 st of June. Earlier it is found most abun- 
dant upon the young growth of poplars along the bayous about bottom- 
land cotton fields. Though common upon cotton it seems to prefer to 
feed and breed upon the new growth of the trees just mentioned so long 
as it remains fresh and growing. Nevertheless, it does considerable 
damage to cotton both by its habits of feeding and those of egg deposi- 
tion. The female possesses two cutting serrated or saw-like blades, 
which fit together and form the ovipositor. With this she makes punc- 
tures for the reception of the eggs. To do this she leaves the central 
stem where the adults are usually found and locates among the tender 
growing portions, especially young " forms" or " squares." The act of 
deposition was twice observed on the involucre or " ruffle " of these por- 
tions. The female braced herself upon all legs, the head and anterior 
portion of the body elevated. The very thin pointed ovipositor was 
then exserted, and by a forcible sawing-like operation was gradually in- 
serted underneath the epidermis. The channel was made concave, the 
distal end almost coming to the surface again. The long, slightly curved, 
cylindrical white egg was then introduced and the ovipositor withdrawn. 
The time occupied by this process was about one or two minutes. After 
a short interval a second egg was laid in like manner alongside of the 
first but slightly in advance of it. A few hours after deposition, slight, 
pale, blister-like swellings were noted over the points where the eggs were 
found. One egg was dissected from the leaf and saved as a reference 
specimen. Unfortunately a larva of Thecla poeas was temporarily placed 
in the same bottle as the form in which the remaining egg was found. 
When next observed the Thecla had eaten a hole directly through the 
portion in which the egg had been deposited, and the latter was there- 
fore destroyed. As a result, the duration of the egg state could not be 
determined. The eating of the egg by Thecla was doubtless only a coin- 
cidence. The recently hatched larva is entirely whitish, and keeps hid- 
den among the very young leaves or the involucres of •• forms" and small 
bolls. The very young carry the abdomen elevated almost at right 
angles with the body. They IWd by puncturing the epidermis at the 
base of the flower bud, or the very young boll, or quite frequently pro- 
ceed to the short, tender peduncles. Soon after this injury is done the 
form or small boll will "flare," turn pale, and dropoff. If examined when
