The lakes of the San .Toaquin Valley, E. W. Hilgard, Ph. 

 D., LL. D. (pp. 1-4). — This gives an interestiog account of investiga- 

 tions with reference to the contraction of the lakes of the upper San 

 Joaquin Valley by evaporation and the consequent effects upon animal 

 life, and the use of these waters for irrigation. The problem of re- 

 claiming the alkaline soils laid bare bj' the recession of the waters is 

 also considered. This bulletin deals especially with Lake Tulare, and 

 is issued in advance of a general report on the subject in order to se- 

 cure, if possible, more light upon the history of these lakes before any 

 definite conclusions are drawn. 



The question as to whether Lake Tulare shall be utilized in the future 

 as an irrigation reservoir or drained and its bed used for agricultural 

 purposes is touched upon. The original area of the lake was over a 

 thousand square miles, and the territory directly aflected by the gen- 

 eral question discussed in the bulletin is more than 6,000 square miles 

 in area. (See monograph on The Physico-geographical and Agricultural 

 Features of California, by E. W. Hilgard, U. S. Census of 1880, Vol. VI,

Notes on insects and insecticides, James Cassidy, B. S. (pp. 



2-20). 



The following insects comparatively new to Colorado were observed in 1888 : The 

 garden web-worm {Eurycreon rantalis) ; the squash bug {Coreus tristis); and the false 

 chinch bug {Xysius angustatus). 



We took the first specimen of Fieris rapae for this season on March 17 ; Pieris proto- 

 dice was flying at this time, and also one of the "skippers " {Eudamus tityrus) ; Vanessa 

 antiopa and V. milberti were seen in numbers March 7. 



The codling moth {Carpocapsa pomonella) was plentiful toward the end of the month 

 of April, but the hackberry butterflies and white-lined morning sphinx moth, so plen- 

 tiful last season, almost disappeared this year. 



Some species of genus Grapta were as early and as numerous as ever. The im])orted 

 currant borer (new here) appeared in force May 26. 



The apple-leaf beetle appeared May 7, and toward the latter part of the month at- 

 tacked the foliage of the grape. 



The moths of the garden web-worm appeared early in April and the false chinch 

 bug and squash bug the first week in June.
