It is the purpose of this paper to present in an introductory manner a systematic treatise of the scale insects of South Dakota, by making an intensive study of all species represented in Brookings County. It can be asserted that this paper is a complete treatise of all species present, but a thorough attempt was made to obtain specimens of all existing species. This treatise involves only the species now present, though at times other forms have been reported. Notes have been included giving the plants, location, and abundance.
