Prior to the first ofJune it seems to prefer the young growth and foliage of poplars andother trees which may grow in the immediate vicinity. Where sharp-shooter work is prevalent in the cotton field, year after year, and thetrees which harbor the insects can be found in the early part of theseason, a single application of kerosene emulsion to the lower parts ofsuch trees or scrub growth might be made to advantage in the monthof May. An insect which at one time did very considerable damage to cottonbolls, particularly those which were far advanced or had burst, is thered bug or cotton stainer, Dysdercus suturellus. This insect was never.

It is probably a West Indian late years, and more especially since cotton culture in Florida hasgiven place to extensive orange culture, it has largely transferred itsattention to the orange fruit. Earlier generations of this insect dam-aged the bolls by puncturing them and sucking the sap, causing themto become diminutive or abortive. Later, however, they entered openbolls, puncturing the seed and damaging the fiber by their yellowishexcrement. These stains were indelible and greatly depreciated thevalue of the cotton in the market. The indelibility and beautiful colorof the stains at one time suggested the use of the insects in making showed that the entire substance of the insect could be 31 converted into a rich
