shrubs at Rutherford, N. J., having apparently emerged en route. A larva of 

 the lepidopteran C. therapon was found in a greenhouse at Bound Brook, N. J., 

 infesting orchids which originally came from Pernambuco. 



Grasshopper control, D. E. Merbhx {New Mexico Sta. Bui. 102 {1916), pp. 32, 

 figs. 19). — This is a discussion of the grasshopper problem in New Mexico, in 

 every part of which State damage is liable to take place. Mention is made of 

 seven species as sources of injury, namely, Melanoplus differentialis, M. bivit- 

 tatvs, M. atlanis, M. femur-rubrum, Hadrotettix trifasciatus, Schistocerca 

 venusta, and Brachystola magna, of which the first three are the most im- 

 portant. The greatest injury is caused to. alfalfa, garden and truck crops, 

 grains, and young fruit trees. 



Their control is deemed practicable through the destruction of breeding places 

 and eggs and of the grasshoppers by poisoning or by capture with machines for 

 that purpose. 



Notes on Anasa andresii, an enemy of cucurbits, T. H. .Tones {Jour. Econ. 

 Ent., 9 {1916), No. 4, pp. 431-434)- — Preliminary notes on the biology of A. 

 andresii, based on observations made by the author and C. E. Smith at Baton 

 Rouge, La., during 1915, are presented. The species is also known to occur in 

 Florida, Texas, New Mexico, c-entral Mexico, and Cuba. Its injury is similar to 

 that caused by A. tristis. 



Triphleps insidiosus as the probable transmitter of corn-ear rot (Diplodia 

 sp., Fusarium sp.), J. A. Hysix)? {Jour. Econ. Ent., 9 {1916), No. 4, PP- 4^5- 

 438). — A report of observations made at New Paris, Me., in the fall of 1912. 

 The form of ear rot caused by Bacterium steioarti was a source of severe in- 

 jury to sweet corn in the large corn-canning districts of the State. 



Some unpublished notes on Pemphigus betas, A. C. Maxson {Jour. Econ. 

 Ent., 9 {1916), No. 5, pp. 500-504). — This is a report of observations on the 

 biology of the sugar beet root louse at Longmont, Colo., by the author, con- 

 ducted in cooperation with the Colorado Experiment Station. 



Dispersion of scale insects by the wind, H. J. Quayle {Jour. Econ. Ent., 

 9 {1916), No. 5, pp. 486-493, fig. 1). — In work at the Citrus Substation at River- 

 side, Cal., the author found young black scales to be carried by the wind as 

 far as 450 feet, the greatest distance at which tanglefoot sheets were set. The 

 young of the red scale were captured on such sheets at distances ranging from 

 30 to 150 feet. 



Beducing the cost of commercial spraying, R. S. ^\■oGLXJM {Jour. Econ. Ent., 

 9 {1916), No. 4, pp. 392-395, fig. 1). — The author describes and presents a dia- 

 gram of a pipe system in a 10-acre orange orchard in southern California, in 

 which the cost of applications of water under high pressure for the control 

 of mealy bugs was found to average 75 per cent less than where the work was 

 done by means of a portable sprayer alone. 



The white-marked tussock moth (Hemerocampa leucostigma), H. C. Ying- 

 LiNG {Mo. Bui. Ohio Sta., 1 {1916), No. 9, pp. 265-210, figs. 3).— A popular ac- 

 count of this moth, which is one of the most important insect enemies of shade 

 and ornamental trees in many cities in Ohio. 



The New Mexico range caterpillar and its control, V. L. Wuldekmuth and 

 D. J. Caffbey {V. S. Dcpt. Agr. Bui. 443 {1916), pp. 12, figs. 12).— This is a re- 

 port of work with Heniileuca olivcB commenced at Koehler, N. Mex., in 1913, 

 and carried on in continuation of that by Ainslie, as previously noted (E. S. R., 

 23, p. 463). Its life history and natural enemies have been given particular 

 attention. 



The pest is said to be of economic importance only in the five counties in 

 the northeastern corner of the State, but a scattering infestation occurs across 

 72628°— 17 5
