As a part of the study on insects injurious to the roots of crops being conducted at the Kansas Agricultural Experiment Station, the writers have devoted considerable time to collecting and making observations on the various species of Scarab~eida belonging to the subfamilies Melolonthine and Pleurosticti. Many of these are injurious, in the larval or adult stages, to crops of various kinds. In many. cases little is known regarding the distribution, life history, habits and food of the different species. During the past winter the writers have studied all of the specimens of the subfamily Pleurosticti in the collection of the Kansas State Agricultural College and have assembled the notes made by'them during the past few years. Most of the literature dealing with Kansas Coleoptera has also been gone over. The present paper is the result of this work and is given at this time in the hope of adding to the meager knowledge of this group and in stimulating others to further observations. The arrangement of Casey (1915) has been followed in listing the species. Rhombonalia comes Casey. Trego, Russell and Wallace counties. June, July. Casey (1915, p. 6) also reports it from Rooks county.
