larger leaves as many as several hundreds, are eaten into and through the leaves i 

 in fact, large portions of the foliage are often completely eaten. 



In the Province of Quebec there are five different kinds of flea-beetles which 

 I should like to direct special attention to at this meeting. These in the order of 

 their importance are as follows : 



THE TURNIP FLEA-BEETLE, (Phyllotreta vittata Fab.) 



This is one of the commonest and most regularly-occurring of the destructive 

 flea-beetles which attack vegetables. It is, also, sometimes troublesome in flower 

 gardens, attacking foliage of stocks and wall flowers. It is a small species of a 

 shining-black colour and in length about one-sixth of an inch. On each wing- 

 cover there is a wavy band of yellow. The over-wintering beetles appear ear^ly 

 in the season, and in the latter half of May and June much injury is done to

young radishes, turnips, cabbages and other Cruciferous plants. The chief damage 

 is to the seed leaves directly these appear above ground and just when the young 

 plants can least withstand such attack. Later, when the rough, true, leaves are 

 formed, the plants, as a rule, are able to make more growth each day than the 

 beetles can destroy. The female beetles deposit their tiny, white eggs upon the 

 roots of the plants and the young grubs feed thereon oftentimes doing consider- 

 able injury; it is probable, however, that this injury is largely confined to weeds 

 belonging to the mustard family. 



THE POTATO FLEA-BEETLE (Bpitrix cucumcris Harr.) 



One of the most destructive of the flea-beetles which occur in Canada is 

 the Potato Plea-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, pumpkins, wonder- 

 berry and other plants. As a rule, the insect is more numerous in hot, dry seasons. 

 The beetles pass the winter in dry sheltered spots and make their appearance
