ting Flea, Burrcnving Flea. A variety of flea 

 ■found in Brazil, Guiana, Mexico, West Indies, and 

 recently (1872) introduced into Africa, Congo, Ga- 

 boon, from Brazil. It lives in woods, on plants, dry 

 lerbage and sand, and attacks man, sheep, goats, 

 attic, horses, mules, asses, dogs, and especially 

 igs. Its attacks show preference for the feet, caus- 

 ng gangrenous wounds, arthritis, necrosis, fistulse, 

 :>ss of phalanges. Among animals the ears are 

 frequently attacked. Immediate extraction, care being 

 iken not to injure the parasites for fear of perfe- 

 cting the ovigerous sac and allowing the eggs to 

 scape in the wound, is recommended ; also appli- 

 cations of grease. In the western United States, 

 re harvest-mite (Leptus autumnalis) has been con- 

 osed with this parasite and called chigger. — Sarcop-
