accompanied by the statement that the material was collected in British Columbia 

 at Hilltont's, near Abbotsford, and that the larva appears to mine one needle of the 

 whorl and then forsakes its gallery and spins a slight cocoon between the needles, 

 the adult issuing the latter part of July as evidenced by the forwarding of moths by 

 Doctor J. S. Boyce, July 21st. The general character of the work is suggestive of our 

 native pine leaf miner, Paralechia pinifoliella Chambs., except that this insect pu- 

 pates in a loose cocoon constructed on the outside of the needles. We are informed 

 by Doctor August Busck, who kindly determined the species, that the insect has 

 never hitherto been recorded from outside of Europe.

Green Soldier Bug. Nezara hilaris Say, has recently appeared in the role of a 

 destructive peach pest in Davis and adjacent counties, Utah. One orchardist with 

 large holdings has lost heavily twice during the past four years. Specimens taken in 

 this orchard were identified by Dr. E. P. Van Duzee who states that tho the insect is 

 generally distributed throughout the West it has not previously been reported as a 

 pest. In all respects the situation in the orchard above cited seems to be identical 

 with that described by Whitmarsh in the Ohio Agricultural Experiment Station 

 Bulletin No. 310. In a brief article written for the Utah Farmer the writer of this 

 note has suggested the burning of all leaves, trash and debris in the orchard among 

 infested trees during the winter, or opening these to the action of the elements. 

 It is further suggested in the absence of accumulations of leaves etc., that small 

 piles of leaves, straw, weeds, dry manure or similar material be provided as inviting 

 hibernating sites late in September and that these be prevented from blowing away 

 by suitable materials such as large weeds or light brush.

Effect of Water on Larvae of Bulb Flies. It has been rumored by Dutch bulb 

 brokers that the narcissus fly and the lesser bulb fly could be controlled by immersing 

 the bulbs in water at room temperature for a period of twenty-four hours. 



In order to prove or disprove this rumor, the following experiments were con- 

 ducted. 



I. Seven larvae of the Narcissus Fly (Merodon equestris Fab.) were placed in 

 water at room temperature, October 20, 1922. 



7 larvae lived 1 day. 

 3 larvae lived 3 days. 



1 larvae lived 4 days. 



II. Seven larvae of the lesser bulb fly {Eumerus strigatus Fallen) were placed in 

 water at room temperature, October 21, 1922. 



7 larvae lived 2 days. 

 6 larvae lived 3 days. 



2 larvae lived 7 days. 

 1 larvae lived 9 days.
