188 TRANSACTIONS OF THE ILLINOIS 



swelling on the last segment. It appears to feed chiefly on the decaying 

 roots of different trees, and, so far as known, is not injurious to vege- 

 tation. 



The beetle, which is found throughout the State, but . more abund- 

 antly in the central than the southern part, flies and feeds by day, and is 

 most generally found in July and August. It attacks the foliage of grape- 

 vines, upon which it chiefly subsists, the Virginia creeper being the only 

 other plant it touches, so far as known. 



Although so generally distributed, it usually occurs in such limited 

 numbers that the injury it inflicts is small. Being day-feeders, of large 

 size, and rather slow in their movements, they can easily be gathered by 

 hand when they appear in sufficient numbers to threaten injury to the 

 vines ; and as this is a specific it is useless to seek for or try any other. 



Spec. Char. Imago. — Claws simple, not cleft, but one on each tarsus larger and 

 stouter than the other ; the antennse as in the preceding species ; elypens not distinct 

 from the face, there being no transverse indented line or mark between the two. The 

 front of the head, the broad, flat face, is usually yellowish or bronzed, while the poste- 

 rior part is greenish with a coppery lustre, the middle portion sometimes brownish 

 yellow. The thorax brownish yellow or clay colored, and marked with a black dot on 

 each side. The elytra colored as the thorax, and each case is marked with three black 

 dots, which are ranged nearly in a longitudinal line on the outer half; the scutellum is 

 green. 



Is large and oval-shaped, about one inch long and half an inch or more in width, 

 smooth and shining ; the under side deep bronze or blackish green. 



Family Cetoniid.^. 



Very closely related to the last family are certain metallic-colored 

 beetles which, from certain structural differences of minor importance, 

 have been brought together under the above family name. The claws of 

 the feet are simple and of equal size, not split ; the anterior coxae, or 

 pieces by which the front legs are attached to the body, are conical and 

 prominent ; antennae with a club composed of leaf-like joints, as the pre- 

 vious species. 



Eiiryomia inda, Linn. The Indian Cetonian. 



This species, which varies in length from a little over a half to nearly 

 two-thirds of an inch, is of a dark, coppery brown color, sometimes of a 

 dark olive green with a coppery lustre, with yellowish hairs, and sprinkled 

 with black dots. It makes its appearance in the latter part of spring or 

 early in the summer, from the latter part of April to the first part of June, 

 when it may be seen often in considerable numbers about groves of trees, 

 on hedges, and on the shrubbery and weeds in fields. The second brood 

 makes its appearance in the southern part of the State as early as the 

 middle or latter part of August, but somewhat later farther north. At 

 this time it is frequently quite abundant on the flowers of various weeds, 

 especially the golden rod. 

 ' It is chiefly injurious in the beetle state, eating into fruit, especially 



peaches, of which it is particularly fond, and to which it sometimes does 

 considerable injury.
