 and body. True legs and prolegs pale yellowish, the hooks of the 

 latter yellowish brown. 



Described from living caterpillars October 14, 1913. 



Remedial measures. The cutting off and burning of the infested 

 leaves during fall or early spring would undoubtedly result in 

 destroying many of the pests and, if persistently followed up, might 

 prove the most satisfactory method of controlling the insect. It 

 is very possible that thorough spraying with a contact insecticide, 

 such as black leaf 40 (diluted approximately i to 800) to which 

 soap has been added to increase its adhesiveness, would prove 

 effective if the application were made early in July for the purpose 

 of destroying the young caterpillars before they are well shel- 

 tered by the leaf tissues.

WHITE GRUBS AND JUNE BEETLES 



The extensive injury of last year by white grubs was followed by 

 a considerable disappearance of the pests last spring, due in part, 

 at least, to the activity of natural enemies and the influence of other 

 adverse factors. It would appear from conditions as they now 

 exist that comparatively few white grubs will be found in the soil 

 in 191 5, owing to the fact that no very large number lived through 

 the season and could therefore be expected to appear as beetles in 

 the spring of 1914. 



Observations of 1913. A sample digging in a slight hollow on 

 the farm of Mr W. S. Miller, East Greenbush, included approxi- 

 mately one and one-half square feet and uncovered nine nearly 

 full-grown white grubs, four adults of Lachnosterna fusca 

 Froh. and the cocoon of a parasite, probably that of T i p h i a 

 i n o r n a t a Say. Most of the insects were found at a depth of 

 approximately 15 inches. A second sample digging near the first
