December, '12] brittoX: notes FROM CONNECTICUT 465 



1912, page 297, as P. dentatus. The work of this insect, which will 

 be described in the report mentioned above, resembles that of the peach 

 sawfly, P. persicum MacG., studied fiv^ years ago by Mr. Walden, 

 and which is still doing sufficient damage in some Connecticut orchards, 

 to warrant the spraying with lead arsenate of several thousand trees 

 in 1912. 



Studies are also in progress upon the white pine weevil, Pissodes 

 strohi Peck., and other insects attacking the pine trees in Connecticut. 



The cold wet spring seemed favorable for the increase of aphid s of 

 nearly all kinds. The rosy apple aphis, A. sorbi Kalt., was more abun- 

 dant and caused more injury than since 1909, and the green apple 

 aphis, A. pomi DeG. was also common. 



White grubs, Lachnosterna, did more damage than I have seen in 

 the state during a residence of eighteen years. Not only were grass 

 fields injured, but the joots of corn and strawberries were eaten, and 

 in some, cases the potato crop was nearly destroj-ed by them. In one 

 forest nursery nearly 25 per cent, of the seedling pines, spruce and 

 deciduous trees were eaten off under ground. 



The fall army worm, haphygma friigiperda S. & A., was received 

 from Stonington, Groton and from two different localities in New 

 Haven in September. In three places it was devastating lawns, and 

 in the other case it was feeding upon a field of millet. 



The flight of the cotton moth, Alabama argillacea Hubn., was much 

 less noticeable than in 1911, and occurred more than two weeks later 

 in the season. Around New Haven the moths were not nearly so 

 abundant as last year, but were most numerous on October 11 and 

 12. In 1911 the date of their greatest abundance was September 26. 



Good progress has been made in the control of the gypsy moth, 

 Porthetria dispar Linn. At Stonington no caterpillars have been 

 found since 1910, and it is regarded as wholly exterminated there. At 

 Wallingford, 26 caterpillars were found last summer where 1,551 

 were taken in 1911 and 8,936 in 1910. Both localities will be watched 

 for some time and in a few weeks, both state and federal scouts ^all 

 examine them for egg masses. 



The brown-tail moth, Euprodis chrysorrhoea Linn., has spread 

 southward slightly since last year, involving portions of the towns of 

 Brooklyn, Plainfield and Sterling. An isolated colony was discovered 

 during the summer at Norwich several miles southward and a single 

 winter nest was found at Stafford Springs several miles west of the 

 previousl}^ infested area near the northern border of the state. 



The birch leaf skeletonizer, Buccidatrix canadensisella Chamb., 

 though much less abundant in the eastern portion of the state than in 

 1910, was found over the entire state as in 1911, and Avas particularly
