296 Forty-sixth Report on the State Museum 



The cabbage Plusia, Plusia brassicoe (Riley), which is so great a 

 pest to cabbage growers in tlie southern States, but is by no means 

 common in the State of New York (see Second Report on the Insects of 

 JVew York), has been complained of as giving much trouble in a green- 

 house at Garden City, L. I., N. Y. Rev. Dr. Cox has written of it : 

 " The caterpillar sj>ecially affects young parsley, but will also feed con- 

 tinuously on heliotrope, pelargium, and, in fact, on almost any green 

 thing." 



The canker-worm, Anisopteryx vernata (Peck), was so abundant in 

 some orchards in Monroe county as to have nearly destroyed the 

 foliage. Orchards in Cooperstown, Otsego county, were so despoiled 

 by the caterpillars as to present the appearance of having been scorched 

 and shriveled by fire. 



The apple-worm of the codling-moth, Garptocapsa poinonella, was 

 lesi injurious than usual throughout most of the State. An extensive 

 fruit-grower and nurseryman of Rochester has written me of it : 

 " Codling-moths in our orchards were almost extinct, it being difficult 

 to find an apple with the larva or its burrows in it. I can not account 

 for this, as ordinarily they are very abundant with us." 



Although I have stated that nothing had been reported to me of 

 injuries from the eye-spotted bud-moth, Tmetocera ocellana (Schiff.), 

 during the year, I have since learned, on special inquiry, that it has 

 been continuing its ravages in Western New York, Avithout diminution, 

 but rather on the increase, and that it threatens to become a permanent 

 pest. 



The cow horn fl}^, Ilmmatohia serrata R. Desv., the introduction 

 of which into New York was announced in my preceding report, has 

 during the year become generally distributed over the State. It is 

 known to me to occur in forty-four of the sixty counties, and with 

 scarcely a doubt is present in each one. The rapidity with which this 

 insect has spread throughout the country is almost, or quite, without a 

 parallel in the histories of our imported pests. First know^n in the 

 United States only six years ago, it has at the present time become an 

 annoying pest to cattle in New England, Florida, Mississippi, Kansas, 

 and many of the intermediate States, and in Canada from the western 

 part of the Province almost to Quebec. 



Severe injuries to potatoes and to strawberry plants from the white 

 grub of, probably, Lachnosterna fusca (Frohl.), were reported from 

 Cattaraugus county. Examples, for identification, of Lachnosterna 

 trlstis (Fabr.) were received from Mr. J. S. Smart, of Cambridge,
