. Bulletin of the Department of Agriculture. Agriculture. THE GREEN JUNE BEETLE. 3 from C. sobrina are in the highest degree inconstant, and that there are no means of defining the two species. All that can be said is that C. mutabilis is, in the great majority of its individuals, larger and broader. The shape of the clypeal horn is very variable, and its varieties do not correspond with variations in size, breadth, and color, large and robust specimens of the typical mutabilis having the horn either dilated toward the apex, parallel-sided, or triangular, and the same diversities may be seen in small and slender oblong examples of C sobrina. It is the same with regard to form and color; for it is far from the case that the large and broad examples (C. niutabilis) only are unicolorous; smaller and narrower individuals exist equally unicolorous and of nearly all the color-varieties displayed by the larger set. It is true that the variegated varieties described by Burmeister under C. sobrina are, as a rule, smaller than the others; but they are connected by the most finely graduated series of variations, so that it is impossible to draw a distinction between the two series. The case is a very difficult one to deal with. It would not be satisfactory, and scarcely practicable, to include under one specific diagnosis all the numerous varieties, some of which are possibly local, thus presenting an interesting study to future collectors and students; the better course seems to be to treat the more distinct separately, giving the locali- ties of each. DESCRIPTIVE. The beetle (fig. 1) is larger and more robust than the common brown May and June beetles (Phyllophaga), measuring from three- fourths to a full inch or more in length, and about one-half inch wide. The color varies from dull brown with irregular stripes of green to beautiful uniform velvet green, the margins of the body being usually light brown varying to orange yellow. The lower surface is metallic greenish
