This genus, under the name of 

 turnip fly, is only too well known 

 throughout the county, as it at 

 times works serious havoc on the 

 turnip crop while still in the 

 smooth leaf or cotyledon stage. P. 

 nemorum is the dominant species, 

 but in 1902 several fields about 

 St. Columb were badly attacked by 

 P. undulata. In the spring of 

 1903 the foliage of the early pota- 

 toes at St. Mary's, Stilly, was injured 

 by P. atra. A few years ago a field 

 of dredge corn near St. Agnes was 

 practically smothered with charlock, 

 but about the beginning of June 

 P. vittula was noticed in great 

 numbers on the weed, and in a 

 fortnight every visible charlock leaf 

 was completely riddled
