228 SECOND REPORT OF THE STATE ENTOMOLOGIST. 



noticed on apple ; other food-plants ; characteristics o{\.\\q Geovietridce; 

 will probably not prove very injurious ; may be removed from trees by 

 jarring. 



Destructive Elm-leaf Beetle — Galerucella xanthomelsna Schrank. 

 (Country Gentleman, for October 12, 1882, xlvii, p. 805, c. 1-2 — 38 

 cm.) 



Identified from leaf injuries in Bound Brook, N. J. Depredations in 

 N. Y., N. J. and southward ; its appearance. Spra3'ing with Paris green 

 and water, jarring and boxing about the base of trees recommended for 

 its destruction. 



A New Principle in Protection from Insect Attack. [Read before the 

 Western N. Y. Horticultural Society, at its Annual Meeting, January 

 25, 1882.] (Proceed. Western N. Y. Horticultural Society, for 1882, 

 pp. 52-66. Separate, with one-half title p. cover, pp. 15 [March, 1882.]) 

 Preventives preferable to remedies ; strongly odorous substances, 

 available for the prevention of egg-deposit; insects guided in oviposi- 

 tion by the sense of smell rather than by sight; acuteness of this 

 sense in man and animals; the probable location of smelling organs in 

 insects; instances of attraction, sexual and otherwise, by odors; scent- 

 organs and their importance ; counterodorants and how they may pre- 

 vent egg-deposit ; the results of protection by this method ; the aim of 

 practical entomology. 



A Rose Leaf Insect. (Country Gentleman, for March i, 1883, xlviii, p. 

 169, c. 2 — 17 cm.) 



A caterpillar feeding on rose leaves in a green-house in Westchester 

 Co., N. Y., identified as Penthitia nimbatana (Clem.). The caterpillar 

 briefly described, its habits mentioned, and method proposed for its 

 destruction. 



Of Interest to Flower Growers — A New Enemy Found. (Troy Daily 

 Times, for April 2, 1883.) 



Discovery of a species of caterpillar, feeding in the green-house of 

 Dr. R. H. Sabin, Troy, N. Y., upon heliotrope, geranium, wandering 

 jew {Tradescaiitia), etc.; features of the caterpillar and cocoon; is 

 probably Plusia dyaus Grote, although seemingly differing somewhat 

 from that species. 



The Bean Weevil. (Country Gentleman, for April 19, 1883, xlviii, p. 

 317, c. 3—16 cm.) 



Identification of Bruchus fabce Riley, from Delhi, N. Y. For history 

 of the species, reference is made to C. G. of December 8, 1881. The 

 apartments where they are found at this season should be searched for 

 the living individuals, which should be killed; and all beans should be 

 kept during the winter in tight vessels or bags to prevent the escape 

 and distribution of the beetle.
