A species of cotton infesting Bucculatrix (Family Lyonetiidae) described as B. gossyPiella Morrill,1 infests wild and cultivated cottons in the states of Sonora and Sinaloa, Mexico. The adults closely resemble another cotton infesting speeies, B. thurberiella Busck, but can be separated by the genitalia in both sexes, while the egg and larval stages of the two species are strikingly different. The larvae of B. gossyPiella have the peculiar habit of boring in woody or hard tissues of the plant, such as stalks, branches, carpels of green bolls, leaf petioles and larger leaf veins as well as in the leaf blades and bracts with decided preference for the harder parts. Characteristic reddish spots are produced by the work of the larva in the plant tissues. Damage appears to be confined to the staining of the lint and to producing deformed and imperfectly opened bolls, usually amounting to between 10 and 30 per cent of the crop. Observations to date indicate that early planting favors maximum damage and late planting favors minimum damage but local concerted action as to delayed planting and clearing of old cotton fields may be necessary where large acreages are involved.
