INSECT NOTES FROM MARYLAND FOR 1906. 39 



U. S. Department of Afrriculture, "\Vashin<jton, D. C, for identifica- 

 tion, but Doctor Hopkins reported that he was unable to identif}^ it 

 even generically. The hirvae collected were about an inch in length, 

 white, with the first three or four segments much broader than the 

 remaining. They work below the surface of the ground in the sap- 

 wood of the pole, some penetrating an inch or more into the wood. 

 The pole from which our specimens were collected was very badly in- 

 fested, there being probably four dozen borers in it. The borers 

 weakened it so much at the surface of the ground that it had to be 

 removed. The infested butt has been secured and placed in the in- 

 sectary in tlie hope that adult s])ecimens of the insect may l)e secured.

The leaf feeders, such as the yellow-necked apple-tree caterpillar 

 {Datcma ministra Dru.), the red-humped apple-tree caterpillar {Schi- 

 zura coneinna S. and A.), the hickory tussock moth {Halisidota carym 

 Harr.), and the black walnut worm (Datcma integerrima Grt. and 

 Eob.), have received more attention than usual owing, probably, to 

 the wide-spread interest which led many to keep a close Avatch for 

 the possible occurrence of either the gipsy or brown-tail moths {Por- 

 thetria dispar L. and Evproctis chrysorrlioea L.). A placard, describ- 

 ing these two insects briefly and figuring them in colors, was dis- 

 tributed in many sections of the State where there was likelihood of 

 the pests becoming established. It is gratifying to state that no 

 undoubted evidence of even their casual occu.rrence in New York 

 State was secured, despite newspaper statements to the contrary. 

 Every report regarding these species was followed up and in each 

 instance found to be based upon insufficient information. An occur- 

 rence out of the ordinary was the capture in Albany of a large South 

 American moth {Thymnia zenohia Cramer). 



The scurfy scale [Chionaspis fxirfura Fitch) has continued abun- 

 dant in the Hudson Valley, being especially mnnerous on young fruit 

 trees in the vicinity of Annandale. 



Experiments with the San Jose scale {Aspidiotus peimiciofiiis 

 .Comst.) have been continued and the weight of evidence is decidedly 

 in favor of employing a lime-sul])hur wash, which, if properly pre- 

 pared and thoroughly applied, gives fully as satisfactory results as 

 any other preparation. Several experiments were conducted largely 

 for the purpose of determining Avhether this wash could be further 

 modified to advantage, A lime-sul]:)liur Avash was made in the 

 normal numner, except that the ordinary local burnt lime was re- 

 placed by a finely })repared hydrated magnesium lime known as
