Leaf-Hopper Immigrants of Economic Interest

Herbert Osborn

The leafhoppers of this country have not been given due consideration owing to their small size and inconspicuous character. The restriction to introduced plants and the absence of seasonal cycles are suggestive of immigrants from tropical regions. The egg stage is favorable to the introduction of such species. Observations are given on the introduction and distribution of the following: Idiacerus scurre, I. cognatus, Allygus mixtus, Platymetapius hyalinus, Deltocephalus pulicarius, D. pascuellus, D.ocellaris, D. collinus, D.flavicosta, Euscelis obscurinervis, Draeculacephale reticulata, Cicadula 6-notata, Balclutha punctata, Empoasca fabae, Eupteryx melissae, Tryphlocyba ulmi, T. rosae, Perkinsiella saccharicida and Peregrinus maidis.

Standards for the Training of Men Who are to Enter Professional Entomology Personal Contact With Students

Herbert Osborn

Earlier entomologists presumably had not set standards for training. The problem of standards is worth careful discussion. A great part of our knowledge is gained through personal contact and we lose in proportion as it becomes impossible. The advanced courses permit closer contact; there is also contact later with station and extension workers. Teachers in vocational agriculture frequently have opportunities to discover latent talent. There should be helpful contacts between entomologists and their assistants, partaking of the educational. There is no more ideal training than under the tutelage of a man of large experience. One method of obtaining this is through summer assignments with the Bureau of Entomology or Station Entomologists.

THE LOST LEDRA AGAIN

Herbert Osborn

The interesting note by Prof. Baker on Ledra perdita (Centruchus perdita , A. & S.) deserves notice on account of the mystery which it clears up, and it may also be worth while to add some testimony in the way of corroborative evidence.
