186 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 6 



nearly complete history of economic entomology in Arizona up to the 

 year mentioned is contained in the bulletins and reports of the State 

 Agricultural Experiment Station. This Station was permanently 

 organized in 1890 and two years later Prof. J. W. Toumey, now of the 

 Yale Forestry School, was appointed botanist and entomologist in 

 which capacity he served for about four years, when the title of 

 entomologist was dropped. Professor Toumey's projects for investiga- 

 tion appear to have been confined to plant diseases. Two brief ento- 

 mological bulletins were prepared by him, however, and published by 

 the station.^ Attention should be called here, in passing, to one of 

 Professor Toumey's annual reports which will probably forever rep- 

 resent the irreducible minimum in departmental reports and serve as 

 a standard which those of us subject to attacks of verbosity may well 

 strive to emulate. Thirteen lines with a total of eighty-one words 

 comprised the full text of this report.^ 



In October, 1899, Prof. T. D. A. Cockerell, at that time of the New 

 Mexico Agricultural College,~was engaged by the Arizona station to 

 visit the Salt River Valley and to report upon the entomological con- 

 ditions found there. As a result of this visit Bulletin 32 entitled "Some 

 Insects of the Salt River Valley and Remedies for Them" was issued 

 by the Experiment Station in December, 1899. This bulletin contains 

 many interesting observations along economic lines and is one of our 

 principal sources of information in regard to the status of insect pests 

 in Arizona prior to 1909. 



From 1900 to 1909 Professor Cockerell served as consulting Ento- 

 mologist of the Arizona Station. During this time he contributed 

 historic and descriptive matter and biological notes to Bulletin 56 

 dealing with the date palm scales (Parlatoria hlanchardi) and {Phoeni- 

 cococcus marlatti). During this period, also, various resident mem- 

 bers of the Experiment Station staff ,^ included in their annual reports 

 brief comments and notes on Arizona insects and entomological con- 

 ditions. In regular bulletins, a chapter on "Extermination of Date 

 Palm Scales" was contributed by Director R. H. Forbes to Bulletin 

 56, being based upon field work of which he assumed personal charge; 

 and in Bulletin 58 Dr. J. E. Coit, then horticulturist on the Station 

 Staff, devoted several pages to a discussion of citrus insects with origi- 

 nal records of observations on the soft brown scale (Lecanium hes- 

 periduni),,the citrus thrips {Euthrips citri) and the western leaf -footed 

 plant bug (Leptoglossus zonatus).
