The matter was iiivestiii-ated l»y Mr. Diekerson and traced to the 

 Treiitnii ''Tillies," iVdiu Avhom he dhtained tlie name and address of 

 tlie ])erson who observed the insects. The phice "vvas visited and 

 carefnlly inspected early in September. Xo trace of the gypsj" 

 moth in any stage was observed, and frnm the description that was- 

 given of the cateqiilhirSj it appears certain that a species of Datana 

 was in fanlt, the caterpillars resend)ling those of the gypsy moth 

 to a considerable extent. At all excnts, it seems reasonably sure 

 that up to the present time the gypsy has not actually appeared 

 within onr limits. 



Several iiKpiiries have come frrmi different parts of the State 

 asking information concerning the insect, and specimens as unlike 

 as the cater])illar of the Imperialis moth ha^'e been sent in to deter- 

 mine whether or not it was the gypsy or brown-tail. 



Reports of th(^ occurrence of the insect in Xe\v York City w'ere 

 investigated by the local authorities and proved unfounded, but at 

 Stonington, in (\>nnecticut, a colony has been found and observed 

 by the entomologist in that State and by agents of the United 

 States Department of Agriculture. 



ROOT MAGGOTS. 



llaggots on the roots of Onions and on the various cruciferous; 

 l^lants are more or less trouljlesome each year, sometimes locally, 

 sometimes throughout the entire State, and there are no insects 

 that arc more ditticult to deal wdth. I liave kept track carefully of 

 the experimental work done throughout the country and of the 

 various applications made in our own State in the hope of gaining 

 some information that would enable us to deal wdth them more 

 certainly and effectively. It is renuirkable what a large number of 

 remedial measures have been proposed, how successful they seem 

 to have been in some cases and vvdiat failures they have been with 

 others. It is also puzzling to find that conditions of soil and local- 

 ity seem to affect the action of the materials in a varying way, and 

 how ajiparently eccentric the insects themselves are in their ap- 

 pearance. ^V locality may be badly infested one year and free the 

 next, and the re\erse is equally true. , There may be a series of 

 bad years or a series of exempt periods ; there may be only a single 

 destructive brood a season, or the maggots may be troublesome
