reaching only to the base of the wing-covers. It is a greyish 

 beetle, rather stoutly built, with costate elytra and a spine on 

 each side of the thorax. The most attractive species is Antlio- 

 philax malachiticus Hald., of a brilliant green. It is usually very 

 rare, but Dr. Fletcher had the good luck to capture five examples 

 one day last summer, and stray individuals have been taken on 

 other occasions at Buckingham and Chelsea. Another pretty 

 green beetle, smaller and more highly polished, is Gaurotcs 

 cyanipennis Say, which is at times quite common. The majority 

 of our species belong to the genus Leptura, some of which are 

 prettily banded with yellow, or otherwise ornamented. A com- 

 mon species is L. canadensis Fab., which is black with red 

 shoulders. The forms of this species with all red or all black 

 elytra {erythoptera and cribrata) have not yet been found here. 

 One of our largest and most abundant species is L.proxinia Say, 

 a robust black beetle with yellow elytra tipped with black. 

 L. chrysocovia Kirby is smaller and easily distinguished by its 

 golden pubescence. 



Our remaining forty odd species belong to the sub-family 

 Lamiin^, in which again we find many tribes unrepresented in 

 our fauna. 



Tribe V, Psenocerini, contains only one species, Pscnoccrus 

 snpernotatus Say, a little cylindrical brownish beetle, with four 

 oblique white marks on elytra, it varies in length from one-tenth 

 to one-fourth of an inch ; its larvae feed in the stems of currant- 

 bushes, etc., and it is known as the American currant-borer. 



Tribe VI, Monohammi, is represented by three genera with 

 seven species. Of the four species of Monohammus which in- 

 fest our pines, M. confusor Kirby, is probably familiar to all 

 Ottawa citizens, and it is sometimes referred to as the " Ottawa 

 Cow." It is over an inch long, and while the antenniP of the 

 female arc not much longer than the body, those of the male 

 reach the length of three inches. These long antennie and the 

 long legs make of one of these beetles a very conspicuous 

 object. This species is very distructive to pine timber or logs ; 

 the grubs being very large and with their powerful jaws bur-
