STATE HORTICULTURAL SOCIETY. 189 



Spec. Char. Intago. — 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, dis- 

 tinct, triangular piece, which may he call the humeral or shoulder-piece. Each wing- 

 case is suddenly expanded at the shoulder, and has two longitudinal ridges along the 

 middle portion, which come together near the tip. The tip of the abdomen is exposed. 

 The head and thorax dark cojipeiy brown, thickly covered with yellowish hairs; elytra 

 yellowish brown, reflecting metallic tints and shades, and sprinkled over with small 

 irregular black spots. Under siile black and hairy, w'ilh the edges of the segments and 

 the legs usually of a dull reddish color. 



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



Euryomia melancholica, G. and P. Melancholy Cetonian, 



This is a smaller species than the preceding ; and 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 the latter. The specimens taken 

 in Southern Illinois this season (1875) ^'^'"y somewhat from the typical 

 characters, and appear to approach very near to Say's vestiia, a species 

 which Dr. LeConte says he is unacquainted with ; some of them have the 

 white lines more or less obliterated. 



It has been observed eating into and injuring apples in this State, 

 and appears to take the place of the preceding species in some sections, 

 and may there occasionally prove equally injurious. 



As neither of these species has been traced through its transforma- 

 tions, the only remedy known, in case they should become injurious, is to 

 gather and destroy the beetles. But it is not probable our horticulturists 

 will often be troubled with them to any serious extent. 



Spec. Char. Imago. — Similar in form and general characters to the preceding spe- 

 cies. The face is somewhat elongated and without any cross ridge or line; is strongly 

 deflexed or nearly perpendicular; front margin turned up. Thorax, breast and upper 

 part of the head covered with hair. The scutellum triangular, longer than wide, the 

 posterior angle elongate and acute. The shoulder pieces between the elytra and thorax 

 small and triangular, the side next the elytra being slightly curved. The elytra with 

 two medium ridges, as in the preceding species ; the sutural or inner margin in both 

 species is somewhat, raised so as to form a middle ridge when the cases are closed ; tip 

 of the abdomen exposed. Color, a dark olive green, the elytra having a brownish or 

 coppery tinge and sometimes dark reddish brown, the ridges being rather darker than 

 the other portions of the elytra. About seven abbreviated and more less interru])ted 

 whitish bands cross the elytra ; these are narrow and appear to be made up of trans- 

 versely elongated dots. 



Length about three-eights of an inch ; width a little over half the length. 



Family BUPRESTID^. (Saw -horned Wood-borers.) 



These insects may be easily recognized by their peculiar form, which 

 is somewhat like an elongated narrow shield ; the antennae, which are 

 slender and not clubbed at the end, but of equal size throughout, and 

 furnished on one side with minute saw-like teeth ; by the spine-like pro- 

 longation of the hind margin of the front breast ; and by their metallic 

 colors. The head is usually immersed in the thorax to the eyes. 



The larvae are of two forms, which are quite different from each 

 other. One is a footless grub, more or less flattened, and having the seg- 

 ment immediately behind the head much enlarged in width, while the
