The last issue of the West Indian Bulletin >(Vol. VII, no. 1) contains a valuable paper by Mr. Henry A. Ballon, , Entomologist on the start' of the Imperial Department of Agriculture, on ' Cotton Stainers.' The following extracts are likely to be of interest and give some idea of the scope of the jxiper :— The cotton stainers of the genus Bi/sdercini are widely distributed in the cotton-growing districts of the world. Although a great many species have been catalogued and described, very little has been done in recording their habits and life-histories. The notes on habits and life-histories embodied in this paper have been made in the laboratory of the Imperial Department of Agriculture at Barbados on insects in captivity, which have been received from the other islands, or have been reared from eggs produced by such insects. The present paper contains descriptions of the species known to occur in the Lesser Antilles and Trinidad, a of the species fi'oni tropical and subtropical America, and references to publications in which these species are described or catalogued. Two species and one variety, believed to be new, are described, and notes are added on life-histories; habits, food plants, and on geographical distribution. In the British colonies of the Lesser Antilles, two species of Di/fcfercus have been recognized : D. andreae, Linn., in the Northern Islands, and £>. aniudi-jer, Uhler, in the Southern Islands. In the French Islands—Martinique and Guadeloupe—D. chlauveyi, Lethierry, has been recorded. Specimens of D. andreae that have been show little variation, either in specimens from the same island or in those from the different islands. Specimens of D. aiimdiger that have been examined show that variations in colour, in addition to those indicated by Uhler in the origina
