This species of HaUica which occurred at Nelson, ant on the leaves of strawberry, in the last week of April; 180 specimens were collected from a single plant. It is a larger flea-beetle than HaUica ignita, being about one- sixth of an inch in length and of a bronze colour. The out- break of 1910 is the only definite record we have of injury by this beetle. In the report of the Dominion Entomologist for the year ending March 31, 1911, it is stated that Haltica Jidda was very destructive to turnips and cabbages at Half Way Lake, Alta. Upon further study, however, we find that the species is certainly not evicta, but that it is at least closely allied to ignila in which the ante-basal groove of the thorax is deep and continuous. • The Potato Flea-beetle, (Epitrix cucumeris Harr.) One of the most destructive of the flea-beetles which occur in Canada is the Potato Flea-beetle, a very small species, measuring from about one-sixteenth of an inch to one-twelfth of an inch in length, black in colour with pale-reddish legs. The foliage of potato and tomato are freely attacked by the beetles, which eat numerous small holes in the leaves. In addition, the beetles have been found feeding upon cabbages, cucumbers, beans, tobacco, squashes, pump- kins, wonderberry and other plants. As a rule the insect is more numerous in hot dry seasons. Many reports of injury have been received from Ontario and the eastern proving - as well as from as far west as Vancouver Island, The beetles pass the winter in dry sheltered spots and make their appearance early in spring; the females soon deposit their minute eggs upon the roots of common weeds of the
