continued during tlie summer of 1913, and it was found tbat a mixture of com- 

 mercial lime-sulpliur 1 qt,. lead arsenate paste 8 oz., and water 50 gal., may be 

 safely used to control this pest in August and Seiitember. Tbrougli the use of 

 lime-sulphur in the solution it was possible to double the amount of arsenical 

 previously used without burning the plants, and this mixture satisfactorily con- 

 trolled the caterpillars. Observations showed that the severity of the damage 

 by the caterjiillar was directly proportional to the lateness of the variety. It 

 is stated that if Chinese or other earlier varieties are planted. near Florida 

 velvet or other late varieties, the former will largely escape the ravages of 

 Anticarsia. By planting Florida velvet beans about the edge of a field in which 

 the main crop is China or other early beans, the caterpillars can be largely con- 

 centrated and readily destroyed by spraying with the arsenical. 



A brief statement is given of control measures for the bollworm on tomatoes, 

 a more detailed account of which has been previously noted (E. S. R., 32, p. 

 G52). The cottony cushion scale continued to spread with increasing rapidity, 

 the infestation at Key West being a severe one. Miscellaneous insects noted 

 include the sweet potato root borer ; Ilemichionaspis minor, found at the station 

 grounds infesting Asparagus phimosus; the chrysomelid beetle Trirhadda 'brevi- 

 collis, which was found at Tallahassee damaging pecans ; and Aleyrodes mori 

 found at Gainesville infesting Euonymus americnniis.
