 of the plants thus protected being 4.4 per cent as compared with an infesta- 

 tion of 6 per cent on plants treated with crude carbolic acid emulsion. 



A general account of A Destructive European Pine Sawfly in Connecticut 

 (Diprian [Lophyrus] simile) is next presented by the author (pp. 118-125). 

 This sawfly, an account of which has been previously noted (E. S. R., 34, p.

 the publication of the article mentioned, it has also been found at Derby, Hart-

 erichsonii) (pp. 125-134 >, Avhich, although it has undoubtedly occurred in Con- 

 necticut for many years, was not observed until 1915 when specimens were 

 received from East Canaan. Accounts by Hewitt relating to this pest have 

 been previously noted (E. S. R., 28, p. 658).

The report concludes with a brief discussion of the entomological features 

 of 1915 (pp. 181-183) and of miscellaneous insect notes (pp. 183-191), relating 

 to the banded fleabeetle (Systena tcemata) which was ablndant and caused

 the leaves; unusual galls upon wild rose; the lime tree spanworm (Erannis

 during the year ; the buffalo tree hopper which injured apple twigs at Wethers-
