Die Forstersche Monographie Der Bienen-Gattung Hylaeus F. (Latr.) = Prosopis F. Und Die Prosopis-Sammlung Forsters, J. D. Alfken

A

Aus den meisten Sendungen von Bienen, die ich aus den verschiedensten Gegenden des palaearktischen Faunengebietes zur Bestimmung erhielt, liess sich ersehen, dass die Gattung Prosopis noch immer das Schmerzenskind der Apidensammler- und Forscher ist. Dies wird so bleiben, wean man dabei bebarrt, Individuen als Arten zu beschreiben, wie dies leider auch Forster in seiner Monographie der Gattung Hylaeus tat. 1) Im allgemeinen, nur die Farbe und die aussere Gestalt in Betracht gezogen, gleichen sich viele Arten sehr, uud es lassen sich nur schwer Unterscheidungsmerkmale zwischen ihnen feststellen. Daher ist es auch meistens unmoglich, die Arten nach ihrem Habitus zu unterscheiden …

Hymenoptera Of Alaska, William Harris Ashmead

The following paper on the Hymenoptera of Alaska, by William Harris Ashmead, Assistant Curator, Division of Insects, U. S. National Museum, was originally published in the Proceedings of the Washington Academy of Sciences, vol. IV, pp. 117-274, May 29, 1902. It is here reprinted from the same electrotype plates, so that it may be quoted exactly as if it were the original. The original pagination has been preserved and transferred to the inner or hinge side of the page, where it is enclosed in brackets, thus [118]; while the consecutive pagination of the present volume has been added in the …

Hufvudet medelmåttigt eller stort.

Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.17, William H. Ashmead

An

This tribe, to the initiated, is readily distinguished by the eyes, which are usually quite differently shaped, rarely smooth and shining, and always distinctly facetted, although a few females have small ellipsoidal or somewhat rounded eyes, as in the tribes Photopsidini and Sphaerophthalmini, and therefore, if the greatest care is not given to other characters, could be confused with certain genera in those tribes.

Bulletin No. 84 - The Grain Smuts, Lewis A. Merrill, B. F. Eliason

UAES Bulletins

Farmers are urged to treat all their seed grain with Formalin, during the coming spring, and thus save to the state, next year, thousands of dollars now lost by smut-infested grain.

Formalin can be purchased at any drug store for about seventy-five cents per pound. Pour one pound of Formalin in fifty gallons of water and completely submerge the seed grain, which is loosely held in burlap sacks, for ten minutes. Dry the seed and it is ready for use.

Bulletin No. 85 - Pear-Blight, W. N. Hutt

UAES Bulletins

This bulletin makes no claim to originality of method. It is simply a brief resume of the history and nature of pear-blight, together with the treatment of the disease that we have found to be most successful, during the last two years, at this Experiment Station. The bulletin is published in reply to numerous letters from many parts of the State asking for information regarding the blight of the pear trees, and methods of controlling it.

The Nesting Of A Carpenter Bee, Wilmatte Porter Cockerell

Co

About the middle of August when the flowers are at their best in our mountain canyon (Beulah, New Mexico), and the wild bees and butterflies have a daily surfeit of nectar, this clever little carpenter goes to work to make a storehouse and to provide for the young of the next generation. Many bees and wasps make their nests by cutting out; burrows in trees and bushes, but few work as quickly and skillfully as Clisodon terminalis.

Bulletin No. 83 - Pruning Of Tree And Bush Fruits, W. N. Hutt

UAES Bulletins

"How shall we prune" is a question probably more frequently asked than any other in the whole range of horticulture. To answer it brings forth a second question, viz., "Why do we prune?" Pruning is a means to an end. So then to prune intelligently and therefore successfully, there should be in the mind of the operator some definite purpose. Too often pruning is simply a cutting of the tree without any idea as to the final purpose such cutting is to serve. Such pruning invariably does harm instead of good, and has ruined countless trees. Since the ultimate purpose …
