xA. large blackish fly with bluish abdomen. When cabbage or 

 cauliflower or corned beef is 1)eing" cooked, it is mostly these flies 

 which come about the kitchen door, or inside, if the latter is not 

 screened, in large numbers. They lay their eggs, from 300 to 6oo, 

 which quickly hatch, upon meat and vegetables, and are at times a 

 great nuisance. This species is well illustrated on Plate I, Fig. 12. 



Pack-ard says that in the Civil War wounded soldiers lying on 

 the held were tormented by these flies endeavoring to lay eggs in 

 their wounds. AN'ounds on stock should be Cjuickly dressed with 

 weak carbolic acid (one part of carbolic acid to thirty parts of water), 

 and then coated with tar (V. S. Department of Agriculture). If 

 eggs are already in the wounds, they should be removed carefully, 

 the wounds washed with the above carbolic acid solution, and dress- 

 ed w'ith tar. 



THE GREEN BOTTLE FLY. 



Psciidopyrcllia {Lncilia) coniiciiia, Fab. 



Fig. 6, Plate 1, is common on stock, laying its eggs on dung 

 in the pasture. Observed this year as early as ^larch 24th. 



THE BLUE BOTTLE. 

 Lncilia c(csai'. Linne. 



This fly hibernates in the perfect or imago stage, and appears 

 quite early in the spring, laying its eggs in meat, and also, it is said, 

 in the putrid mass of dead insects found in the pitcher plant, vS"ar- 

 raccJiia. The maggots live on the decaying matter, and pupate, but 

 when they emerge as flies they are held as prisoners, and are added 

 to the rotting mass in the plant. This fly also attacks stock. 



THE SCREW-WORM FLY. 



Clirysoniyia (Coinpsoinyia) }naccllaria. Fab. 

 This fly (see illustration) is not only an annoying pest to stock 

 in the South, but it is to be dreaded on account of its pernicious 

 habit of laying eggs in wounds and other openings in cattle and 

 men, sometimes even in the nostrils and ears of human beings sleep- 

 ing out of doors or in unscreened houses. The larvae or maggots, 

 by their acti\'ities in such localities, cause sickness and frequently
