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

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

 which may in those places prove equally injurious. 



As neither of these species have bean traced through their trans- 

 formations, the only remedy known is to gather and destroy the 

 beetles. 



Spec. char. Imago. — The characters are similar to those of the pre- 

 ceding species. 'Face is somewhat elongate, and with no cross ridge 

 or suture; is strongly deflexed, or nearly perpendicular; front mar- 

 gin turned up. Thorax, breast and upper part of the head covered 

 with hair. The scuttellum triangular, longer than wide; the poste- 

 rior angle elongate and acute. The pieces between the thorax and 

 shoulders of the elytra small and triangular ; the side next the ely- 

 tra slightly curved; elytra with two ridges as in the preceding spe- 

 cies, and tip of the abdomen exposed ; the sutural margin in both 

 species is somewhat raised so as to form a middle ridge when the 

 cases are closed ; color, a dark, olive green, the elytra havirg a brown- 

 ish or coppery tinge, and sometimes of a dark, reddish-brown color, 

 the ridges being rather darker than the other portions of the elytra. 

 .Seven abbreviated and more or less interrupted whitish lines or 

 bands cross the elytra ; these are narrow, and appear to be made up of 

 elongated dots. Length about three-eigths of an inch, width a little 

 over one-half the length. 



BUPRESTID.E. (Saw-horned Wood-borers.) 



These insects mav be easily recognized by their peculiar form 

 shown in the annexed cut ; their antenna, 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 prolongation of 

 the hind margin of the front breast, and by their metahc colors. The 

 head appears as though it had been pressed back into the thorax. 



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

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

 segment immediatelv behind the head much enlarged in width, 

 while the remaining'segments are much narrower. The other form 

 does not have the first segment unusually enlarged, the whole body 

 being somewhat slender and tapering posteriorly, and each of the 

 iirst three segments with a pair of small legs set wide apart. 



These larva? are wood-borers, yet, as a rule, they appear to attack 

 those trees which are suffering from some disease or impaired vital- 

 itv, but yet not in absolute decay. 



'Family Characters— Arxtenruz finely serrate; not clubbed or en- 

 larged at the tip, but similar throughout ; body usually of an elon- 

 gate, oval or long elliptical form in outline, of a firm, inflexible tex- 

 ture ; head usually deeply immersed in the thorax ; scuttellum very 

 email and sometimes wholly wanting ; the presternum prolonged be- 

 hind to a point which is received into a corresponding notch or cav- 

 ity in the roeso sternum. This part (prosternum) is also advanced 

 in front, but not in a point, but like a muffler. Most of these char- 

 acters are also common to the next family; the Buprestidx being 

 distinguished by the finely serrate antenna, and by the fact that the 

 prosternal point is immovable, that the anterior and middle legs are 

 furnished with trochanters and the metalic colors.
