JULUS OERULEOCINCTUS, WITH ASSOCIATED POTATO-SCAB 4< 



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

 with Julus, at gcarsdale, 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. 

 The same infesting scabby potatoes, 446. Is a well-known pctato pest, 446. Its injuries 

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

 scabby potatoes, 446. Potato scab may be caused by a fuDgus, 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. Epidapus scabies largely instrumental in causing scab, 447. What the fly is, 447. 

 How potato-scab may be prevented: by planting unicfested 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 thousand- legged
