western part of the Province it is unfortunately sometimes very destructive. At 



London it has been accused by Professor Saunders and Mr. Reed 



of doing great injury to trees throughout the city. The larvae 



bore into the solid wood, both of young trees and of large ones, 



and Dr. Packard cites several cases where healthy, vigorous 



trees perished from their attacks. The beetle is nearly an inch long, 



of a rich velvet-black above with bright yellow markings. The head 



is yellow , the thorax has two yellow transverse lines on each side ; 



the wing-covers have a yellow band across the middle, above which a 



" W " with oblique bands over it ; the tips yellow, with a black dot 



on each, and band above ; legs and under parts of body yellowish. 



The larva is hatched in July or August, from an egg deposited on, or 



Fi g- 18, in, the bark, and burrows at first between the bark and wood, but the 



following spring, when large, it bores into the solid wood. Like the <f apple borer" it 



should be searched for by the sawdust ejected from the burrow, and be dug out. 



38. Calloides nobilis, Say. This beetle is much rarer than the former, and resembles 

 it in general appearance, except that the yellow markings are not so numerous or extensive. 

 I have captured it on maple trees in June. It is recorded as infesting the chestnut, of 

 which we have none here. 



39. Xylotrechus colonus, Fabr. A beetle similar in shape to the preceding species, 

 but averaging only about half an inch in length, has been found under the bark of an old 

 sugar-maple (by Mr. G. Hunt). The species bores in the oak also, and I have taken 

 specimens upon hickory. The markings of the elytra are whitish. 



40. Clytanthus ruricola, Oliv. This is a very pretty beetle, which I find upon several 

 trees, including maples. It is nearly of the same size and shape as the preceding beetle, 

 but is of more elegant appearance, and has longer, slenderer legs. It has the rich black 

 and yellow of the maple-borer, but the head is black ; there are no transverse lines on the 

 thorax ; and the elytra lack the yellow tips and middle band. 



41. Bellamira scalaris, Say. This beetle is of a different form, being long and slender, 

 especially the males. I have taken the female ovipositing in a maple stump in July. 

 Her length is over an inch ; the head is constructed behind the eyes so as to form a neck ; 

 the thorax is narrow ; the elytra pretty wide at the shoulders but tapering rapidly to the 

 apex, and shorter than the abdomen. Colour reddish, (sometimes dark), with feet and 

 antennae more yellowish, the elytra glistening with a fine pubescence. This beetle has 

 been found to attack birch. 



42. Dryobius sexfasciatus, Say. This a handsome longicorn recorded by Mr. 0. G. 

 Siewers of Newport, Ky., as found under bark of dead maple, (Can. Entomologist XII., 

 p". 139). As it does not appear to be found in Canada I need not give any description of 

 it here. 



43. Orthosoma brunneum, Forst. This is one of our 

 largest beetles, and its larva is a formidable grub, which may 

 often be found in old pine logs and stumps, and occasionally it 

 occurs in other kinds of wood. I have on two occasions taken 

 the beetles (Fig. 14). under the bark of dead sugar-maples. 



44. Urographis fasciatus, DeGeer. Is a grayish beetle, 

 with several wavy black bands. It is slightly over half an inch 

 lon^, and the abdomen of the female is prolonged into an oviposi- 

 tor that i>iv>trudes beyond the wing covers. It infests also the 

 oak and hickory. 



45. Livjius variegatus, Hald. This is a smaller beetle 

 which I have once or twice captured crawling on the trunks of 

 old sugar maples. 



46. Sape?-da tridentata, Oliv., is the elm-tree borer, which 

 often does great injury to elms. It belongs to a genus which 

 contains several .of our best known borers, among others the apple- 

 tree borer (S. Candida) the linden borer (S. vestita), the poplar 

 borer IS. calcarata) and the hickory borer ^S. discoidea), 1 have
