ENTOMOLOGY. 575 



The imported elm-leaf beetle, H. T. Fernald {Masmrhim'Us >S'^(. Bid. 76, jip. 8, 

 fig. J) . — Notes are presented on the occurrence, distribution, life liiytory, and food 

 plants of this insect. Tlu> most approved remedies are outlined and fortnulas are 

 given for the preparation of suitable insecticides for use against this beetle, such as 

 arsenate of lead, Paris jjreen, kerosene enuilsion, and a mechanical mixture of kero- 

 sene and Avater. It is recommended that trees should be sprayed when the leaves 

 are about half grown, and that the application should l)e repeated during the first 

 week in June. Loose bark on the trunk should l)e scraped off, and the grubs and 

 pupte at the base of the tree may be destroyed by spraying with boiling water or 

 kerosene emulsion. 



Tent caterpillars {Bd. Agr. ILondoii'], Leaflet No. GO, 2>p- -5). — Descriptive and 

 biological notes are given on CUsiocampa neusiria and the Itrown-tail moth. Both 

 species are injurious to various fruit trees, especially apple, plum, and pear, but the 

 first-named species is most common and most destructive. Besides fruit trees, it 

 feeds on oak, elm, hawthorn, and various other trees and shrubs. The brown- 

 tail moth has a somewhat local distribution, but occurs in great numl)ers wherever 

 it is found. The egg bands of C. neusiria should be collected in winter and burned. 

 The tent of the brown-tail moth may be easily detected in winter and cut off and 

 burned. Spraying with Paris green, London purple, or arsenate of lead is also effect- 

 ive against both these insects. 



Observations on the South African locust fungus, G. Lindau {Notizbl. K. 

 Bot. Garten u. Mas., Berlin, 3(1901), Xo. 26, ]>p. 119-126, jd. i).— The author 

 describes in detail the growth and morphological characters of this si>ecies of fungus, 

 which is described under the name Miicor lociisticida. Culture experiments with this 

 fungus indicated that it can be successfully grown on any of the usual media, and if 

 it proves to be as effective as already suspected its culture on a commercial scale will 

 be an easy matter. 



Spraying calendar {Pennsylvania Depi. Agr. Bpt. 1000, pi. 1, pp. 890-900). — 

 Brief directions are given for the preparation and application of insecticides and 

 fungicides in the case of the common insect jjests and fungus diseases of various 

 cultivated crops. 



Insect powders {Agr. Jour. Cape Good Hoj)e, 19 {1901), No. 4, pp. 266-270).— 

 Brief compiled notes are presented on the history, cultivation, preparation for use, 

 and active principles of a species of pyrethrum which is used in the preparation of 

 insect powders. 



The new law concerning insect pests, W. E. Britton {Connecticut State Sta. 

 Bid. 134, pp- 6) . — A law concerning insect pests was passed by the Connecticut legis- 

 lature on June 4, 1901. and approved by the governor on June 10. A copy of the

How to keep white ants from a building ( Queensland Agr. Jour. , 9 { 1901 ) , No. 2, 

 p. 279). — Directions are given for preventing the entrance of white ants into frame 

 buildings in countries where these insects are a serious menace to such structures. 

 The stumps on which the fi-amework rests should be solid wood, without cracks or 

 rotten places. All such stumps should be treated with hot coal tar so that this sul)- 

 stance may penetrate as deeply as possible. Veranda steps should be connected A\ith 

 the ground by pillars treated in the same manner, and no lumber or rubbish should 

 be allowed to accumulate under the building. 



Directions for collecting and preserving insects and plants, E. M. Wilcox 

 {Oklahoma Sta. Circ. of Inform. 3, pp. l'),figs. 10). — In this bulletin a re(juest is made 

 for observations and specimens from voluntary observers throughout the Territory. 

 Directions are given for collecting, preserving, mounting, and shipping specimens of 

 insects and plants to the station.
