injured by the powder post beetle (Lyctus striatus Mels.).¢ White 
ash panels and trimmings were infested and quite a number of small 
holes were visible. On removing a section of the wood, both beetles 
and larve were found. Cars constructed with the same kind of wood 
and received from other companies showed no signs of injury 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. ©. 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 XIT 
of the seventeen-year locust (Zibicen septendecim Linn.) would ap- 
pear in Vinton County, Ohio, in 1904, was correct. Letters request- 
ing information were sent to the crop correspondents of that county, 
and my assistant, Mr. E. C. Cotton, interviewed several people in 
each township and made examinations early in June, but no trace of 
the insect could be found. Larve 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 1914. 
An examination of the vineyards along Lake Erie made during 
the early summer showed that the grapevine rootworm (/7idia viticida 
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, 
hence the larve 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 offer a partial 
explanation of the small number of beetles that developed this year. 
The grape fruit-moth (Polychrosis viteana 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 
yellowish larvee were found within. Other growers had noticed the
