It was found quite abundant in an orchard of young trees iu East Greenbush, where seven good sized grubs were taken from the base of a small tree not over 3 inches in diameter. There is no doubt that persistent and thorough digging or cut- ting out of these grubs and the use of a protective wrapper at the base of the trees are all that is necessary to control this pest. The cost of these measures is very slight compared with the value of the orchard. Red-headed flea beetle, S y s t e n a frontalis Forst. The destructive tendencies of this little black, red-headed flea beetle have been noticed in a recent report. This year it was received, in company with other insects, as a depredator on grapevines. It probably, as in preceding cases, had weeds, and, when numerous, turned its atten- tion to more valuable plants. Forest tent-caterpillar, Clisiocampa disstria Hlibn. This insect has been a most serious pest in New York state for the Fig. 11 Eed headed flea bee- last' four or five years, and in localities here fcle much enlarged (original) and there it has proved exceedingly destructive this sea- son. The outbreak of 1901, so far as could be learned, was much more limited in area than in earlier years and confined largely to sections adjacent to where the insect had been specially abundant previously. The caterpillar ap- pears as a rule to be unable to exist in large numbers in one locality for more than four or five years in succes- sion. This is probably to be explained by the local activity of natural enemies. Another marked feature has been the increasing predominance of t!ue pest in orchards. It is perhaps hardly necessary to add that most of the injuries in orchards could have been pre
