The scutellum is wanting, the place being occupied by a posterior 

 extension of the thorax, -which part is triangular, thus giving the 

 whole thorax taken together the form of a trapezoid. The head is quad- 

 rate, with an obovate extension in front ; upper surface with a ridge 

 on each margin and one in ihe middle. Elytra with rounded shoul- 

 ders and slightly narrowing posteriorly, with two slight longitudinal 

 ridges on each case. General color a beautiful velvety-green, with 

 broad margin of orange-yellow around the elytra. 



Length three-quarters of an inch : width of elytra across the shoul- 

 ders about one-half the length. 



This is the June-bug of some sections. 



euryomia inda — Linn. (The Indian Cetonian.) 



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

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

 <lark, 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, April or May, and may be seen in considerable numbers; it 

 also may be seen about groves of trees and hedges and in the fields. 

 The second brood makes its appearance in September in the southern 

 part of the State, sometimes as early as the latter part of August, be- 

 ing seen frequently quite abundant on the flowers of various weeds, 

 especially on the golden-rod. 



It is chiefly injurious in the beetle state, eating into fruit, espec- 

 ially peaches, of which it is peculiarly fond, and to which it some- 

 times docs considerable injury. 



8pw. char. linage. — The scutellum distinct, its length exceeding its 

 width ; on the outside of each wing-case, at the base between! it and 

 the thorax, is another small triangular piece. Each wing-case'is sud- 

 denly expanded at the shoulder, and has two longitudinal ridges along 

 the middle portion which come together near the tip. The tip of the 

 abdomen exposed. The head and thorax of a dark copper-brown, 

 thickly covered with yellowish hairs; elytra yellowish-brown, reflect- 

 ing metalic tints and shades, and sprinkled over with small, irregular 

 black spots. Underside black and hairy, with the edge of the seg- 

 ments and the legs usually of a dull reddish color. 



Length varies from a little over half to nearly two-thirds of an inch. 



E. melancholica — (i. and P. (The Melancholy Cetonian). 



This is a smaller species than the preceding, being less than on e- 

 half and usually only about two-fifths of an inch in length. It 

 may be known by the dark olive and almost black color of the thorax 

 and wing-cases, and by the transverse waving white lines on th e 

 latter. 



The specimens taken in Southern Illinois this season (1875) vary 

 somewhat from the typical characters and appear to approach very 

 near to Say's vestita, a species which Dr. Le Coute says he is unac- 

 quainted with ; some of them have the transverse white lines mo re 

 <ir less obliterated.
