254 Journal New York Entomological Society. [Vol. vi. 



Mr. Ditmars read a popular paper on the Transformations of Insects, and de- 

 scribed in some details the main characteristics of the different orders. He also ex- 

 hibited a series of prepared specimens of transformations preserved in alcohol and 

 some anatomical models. 



A brief note from Dr. Kunze on Euchloe fiima was read by Mr. Beutenmiiller. 

 He stated that /z'/«<z is single brooded and flies in Pima and Maricopa Co., Arizona, 

 principally during March. Dr. Kunze took it also on February 28, 1898. Pima 

 rifles the flowers of a hirsute plant called Amsinckia spectabilis and stated that he 

 never observed it feeding on any other plants. It is difficult to differentiate between 

 the sexes on the wing, as both are exactly alike in color. Besides the female is very 

 scarce and about in proportion as 1 to 20. 



Mr. Beutenmiiller exhibited about 100 species of Sphingidse from Mr. Schaus' 

 collection. Amongst which were Ambulyx substrigalis, A. rubicosa, Pterogon gor- 

 gonides, Salaspes infernalis, Maruba roseipennis, Amblypterus panopus, etc. 



Meeting of March 15, 1898. 



Held at the American Museum of Natural History. 



President Dr. Love in the chair. Fourteen members and visitors, Messrs. Kear- 

 fott and Southwick, present. 



Mr. Southwick read a paper on the economic entomological work done in the 

 parks of New York City. 



He enumerated and described in detail the various insects and the modes of de- 

 stroying them, the sc aping of the egg-masses and cocoons in winter and the spraying 

 of the foliage in summer. 



Mr. Southwick described the various emulsions for the destruction of insects, and 

 stated that a mixture of London purple against the Elm beetle was very effective. 

 The work against the beetle is begun about the middle of May by spraying and again 

 about June 6th for their larvas with an emulsion of soft soap, kerosene, carbolic acid 

 and water. The various borers are treated with bisulphide of carbon. Fungi which 

 promptly appear after trees have been wounded are scraped off and the affected places 

 painted with celluloid. The bag-worm, Thyridopteryx ephe?nerceformis, formerly very 

 abundant, has almost entirely vanished from the parks by effective work ; similarly the 

 scale-louse, Pulvinaria innumerabilis, formerly common in the parks, has almost entirely 

 disappeared from that place. The speaker pointed out the effective work which is 

 constantly in progress against a number of other injurious insects, such as the Orgyia, 

 different species of Datana, Hyphantria, oyster-shell bark louse (Mytilaspis) and 

 different Hackberry Galls (Pac/iypsyl/a^ . 



In conclusion the speaker showed a number of tools used for economic ento- 

 mological work, such as knives, scrapers, spraying nozzles, etc. 



Mr. Palm exhibited some rare Coleoptera collected by Dr. Kunze in Arizona. 



Mr. Kearfott showed a box of inflated larvse. After discussion adjournment. 



Meeting of April 5, 1898. 

 Held at the American Museum of Natural History. 

 President Dr. Love in the chair. Ten members present. 



Dr. Seifert spoke on experiments of heat and cold upon pupae of Lepidoptera. 

 He stated that larva exposed to an abnormal degree of heat or cold showed no visible
