JULDS C^RDLKOCINCTDS, WITH ASSOCIATED PoTATO-ScAB'' 445 



Why millepeds are brought to the notice of entomologists, 445. Potato, stems infested 

 with Julus, at Scarsdale, N. Y., 445. A similar attack noticed In the "Rural New 

 Yorker," 445. Details of the attack, 445. Referred to the above-named species, 446.

 in Cooperstown, N. Y., to potatoes, 446. Other food plants, 446. Often associated with 

 scabby potatoes, 446. Potato-scab may be caused by a fungus, 446. Another form may 

 result from bacteria presence, 447. Possibly bacteria merely accompany the fungus 

 attack, 447. Prof. Hopkins has shown that a scab may be owing to operations of 

 fungus gnats, 447. Both the scab and rot may be produced by Sciara and Epidapus, 

 447. E^jidopMS scabies largely instrumental in causing scab, 447. What the fly Is, 447. 

 How potato-scab may be prevented: by planting uoinfested seed; use of land free from 

 scab presence; not feeding scabby potatoes to stock; reject barnyard manure for fertil- 

 izing; dig infested potatoes as soon as possible, 447. The corrosive sublimate prevent- 

 ive, 448. Directions for making and using It, 448. Remedies for thoueand- legged
