74 STATE POMOLOGICAL SOCIETY. 



CanJcer Worm or Army Worm. — AnisojJteryx Po7jietaria. — These worms have 

 nearly disappeared from the neighborhood of the writer, having been destroy- 

 ed by a late frost, parasite, or some other agency. Some attempts at destroy- 

 ing them w^ere made Avith partial success, but the very general failure to put 

 in an appearance is due to some cause not human. 



The Currant or Gooseberry Worm, which has so loug deprived many of 

 currants, has mainly moved eastward, and was last season luxuriating in the 

 vicinity of New York city. A very small supply of white hellebore was suf- 

 ficient to destroy the few that remained in this vicinity, but we have a new 

 aspirant for attention. It feeds on the currant and gooseberry leaves, and is 

 named 



EUopia Rihearia. — It is easily distinguished from the other gooseberry 

 worms, from the fact that it is a measuring or span worm, about one inch long 

 when full grown, quite yellow in color, with white and black spots. It appears 

 in June, attains full growth in July, goes into chrysalis state, emerges a yel- 

 low miller with spots, and deposits its eggs, which do not hatch until the fol- 

 lowing summer, — a very fortunate circumstance, as it gives us but one brood 

 for a season. When the worm is disturbed on the bushes, it spins down to the 

 ground like the canker worm. But the unfortunate thing about this visitor 

 is, he seems to relish white hellebore; perhaps he thinks it for an appetizer. 

 I shut up several in a ventilated box with an an abundance of hellebore, but 

 they were alive and in fair condition after a week. C. V. Eiley (the accom- 

 plished entomologist, to whom the fruit-growers are under many obligations), 

 suggested that my hellebore was not good ; but I used some from two difier- 

 ent stores, either of which were effective on other worms. I made a strong de- 

 coction of tobacco, and placed them in it, but it had no more effect upon them 

 than an old pipe does upon an old smoker. I made a strong solution of Bu- 

 chan's carbolic compound, but it would not destroy the EUopia. 



Mr. Eiley suggested Paris green and water on bushes not bearing fruit, but 

 the EUopia had all retired into the pupa state before his suggestion arrived. 

 As there is but one'crop of them in a season, we can hand-pick them. It is 

 recommended to all members of the Society who have stock in this new ar- 

 rival, to experiment next season, and find some easy method of extermination. 



The Colorado Potato Beetle seems to be gradually moving eastward in irreg- 

 ular columns, and is less destructive than at the AVest. It Avas in the midst of 

 us during the last summer, but did not seriously diminish the amount of the 

 potato crop. It is thought by those who have|tried it, that if taken in season 

 they can be exterminated with Paris green, at an expense of about five dollars 

 per acre ; and in some localities a parasite has come to our aid, so that these 

 beetles are by no means a source of so much anxiety as formerly. 



Mr. A. C. Younglove said it is very difficult picking off the new currant 

 worm described by Dr. Sylvester, as they are very active, and hide among the 

 leaves. 



EEPOKT OF THE COMMITTEE ON ORIS'AMENTAL TREES, ETC., BY GEO. ELLWAi^GER. 



There having been fewer novelties introduced than usual in the way of 

 hardy ornamental trees and shrubs during the past year, it has occurred to us 

 that an enumeration of the various hardy Magnolias might prove acceptable 

 in place of our usual report of newly-introduced ornamental trees and shrubs. 



Among the many materials offered to the landscape gardener for the adorn- 

 ment of the lawn, the park and the pleasure ground, the Magnolia, in its
