injured by the powder post beetle {Lyi;tu § striat us Mels.).*^ "V^Hiite 

 ash panels and trimmings were infested and quite a number of small 

 holes Avere visible. On removing a section of the wood, both beetles 

 and larva» were found. Cars constructed with the same kind of wood 

 and received from other companies showed no signs of in]^u\y by this 

 insect. The infested parts had been treated with creosote and corro- 

 sive sublimate, but without beneficial results. Evidently the cars 

 were infested when purchased, and the only remedy seemed to be to 

 replace the infested parts with new wood. 



At the request of Mr. C. L. Marlatt, assistant entomologist of the 

 Bureau of Entomology, an investigation was made to determine 

 whether the record of Dr. G. B. Smith, indicating that Brood XII 

 of the seventeen-year locust {Tihicen septendecim Linn.) would ap- 

 pear in Yinton County, Ohio, in 1004, was correct. Letters request- 

 ing information were sent to the crop correspondents of that county, 

 and my assistant. j\Ir. E. C. Cotton, interviewed several people in 

 each township and made examinations early in June, but no trace of 

 the insect could l)e found. Lar^a^ were found by one man several 

 feet below the surface of the ground while stripping a coal bank on 

 a hillside, but they were only partially grown and evidently belonged 

 to the brood due to appear in 19 14. 



An examination of the vineyards along Lake Erie made during 

 the early sunnner showed that the grapevine root Avorm {Fklia ritlrida 

 Walsh) was not as injurious this year as in the past. This was found 

 to be true in sprayed as well as unsprayed vineyards, and also where 

 the vines had been totally neglected: Some growers are of the opin- 

 ion that the one reason for the small number of beetles present is that 

 all the roots near the surface of the ground have been destroyed, 

 Jience the larva> on hatching have nothing to feed upon and die before 

 burrowing a sufficient distance to reach the vigorous roots. As the 

 worst infested spots are found where the soil is of a sandy character, 

 and as examinations have shown that considerable digging is re- 

 quired before any tender roots are reached, this may oifer a partial 

 explanation of the small number of beetles that developed this year. 



The grai)e fruit-moth {Pohjrhrosk riteana Clem.) continues to 

 do considerable damage, especially to vineyards that are not sprayed 

 with poison early in the season. 



About June 10 Mr. John Maxwell, of Euclid, noticed that some 

 of the blossom buds on his vines had become somewhat enlarged and 

 were turning red ; also that on opening such buds several white or 

 vellowish larviB were found within. Other growers had noticed the
