been experienced and several not usually met with have been in evi-

The unusually hot, dry summer was of course, favorable to the 

 rapid increase of plant lice and the San Jose scale. Cutworms were 

 also very abundant and did much damage, and the elm-leaf beetle 

 was unusually destructive, though in most towns this pest is now 

 quite well kept in check by spraying. It was first found in Nantucket 

 this summer in small numbers, on five or six elms near the center of 

 the town, not as perhaps might have been expected, on the trees 

 nearest the wharves. 



The leopard moth, Zeuzera pyrina L., is now present almost every- 

 where in eastern Massachusetts near the coast, and has even reached 

 Nantucket. It does not seem to have worked its way far inland, how- 

 ever,, and as in other states, its injuries are most pronounced in the 

 cities and larger towns. 



The twelve-spotted asparagus beetle, Crioceris 1 2-punctata L., 

 which has been working its way northward, was taken at Concord 

 and Roslindale near Boston in 1909. It was not observed at Amherst 

 until last summer, which might indicate a more rapid dispersal along 

 the coast than inward. 



The cottony maple scale, Pulvinaria innumerabilis Rathv., has 

 been unusually abundant in the Connecticut Valley this year, many 

 of the soft maples being so thoroughly covered with it as to have made 

 little or no growth. This is the first time for several years that this 

 insect has attracted any attention in the state. 



In 1910 the white birches throughout New England were attacked 

 by the birch-leaf skeletonizer, Bucculatrix canadensisella Chamb., 

 and almost without exception, the leaf tissues were entirely consumed. 

 As scrub birch is so abundant everywhere in this part of the country, 

 much attention was directed to this insect and many inquiries as to 

 the likelihood of the destruction of the trees were received. During 

 the past fall the insect was again in evidence, but to a less degree, 

 only a small portion of the foliage being destroj^ed, and as a whole, 

 the greatest injury appears to have been in localities where the pest 

 was least abundant last year. 



The cutleaved birches so much favored as ornamental trees have 

 had a cUfferent experience. They have suffered equally with the 

 native varieties, but in addition, for the last three years in the Con- 

 necticut Valley at least, they have also been attacked by the bronze 

 birch borer, Agrilus anxius Gory, and in nearly every case where this 

 insect has entered a tree, its death has followed, while the native 

 birches have thus far appeared to be exempt. 



The latter part of May some large chestnut trees in Amherst were
