 stances considerable damage was done, not only by the loss of sap drawn 

 ' ff by these sucking insects, but also by the growth of fungus on the "honey- 

 dew" that is secreted by the larvse on the foliage beneath them. The only 

 remedy for them appeared to be spraying with kerosene emulsion. Where 

 a greenhouse is infested fumigation with hydrocyanic acid gas should be 

 resorted to. The accompanying figures (figs. 3 and 4) represent the char- 

 acteristic forms of the fly and the scale-like covering of the larva ; both are 

 very greatly enlarged.

The Tarnished Plant-bug {Lygus pratensis) was another very abundant 

 insect this year. It w^as first noticed in large numbers on the chrysanthe- 

 mums that had been brought out of doors from the greenhouses ; it attacked 

 their terminal shoots and thus injured and in some cases destroyed the buds 

 and future flowers. It was also to be found on asters and a number of other 

 flo-wering plants in the borders, and on asparagus, beets, carrots, celery,
