Small irregular feeding areas on the ed^ of the leaves indicate the feeding habits of the adult weevil. R. A. Cooley, in the Montana Bulletin No. 55, mentions the fact that the .idults have been noticed occasionally to feed on the roots. Observations at Hatzic, in 1912, in the laboratory showed that leaf stalks are readily devoured. Under strictly natural conditions, however, uninfluenced by any experimental methods, the small areas devoured from the edge of the leaf, are by far the most common indications of the feeding habits of the adult. In Montana, further, it is reported that "the beetles came in such numbers, eating the foliage and boring holes in the 'cms, as to destroy the bed before it got a fair ; No such record as thi- uas been taken in British Columbia, and it would appear that it would be a very poor stand of plants that would suffer in this way under local conditions in British Columbia, and especially in the Lower Fraser valley, where the growth is luxuriant and very rapid.

This leaf represents the worst injuries inflicted by a large number of aduita kept in a confined area during the investigation. No instance has been n'rorded so far in British Columbia where adults of this weevil have completely stripped a plant of its leaves (original). With the larva- feeding on the roots, however, the case is different, and plants may be killed outright. The greatest amount of injury is caused in the spring when, affected also by the heat of the summer sun, heavily infested w
