Life-ldstory. The larva is said to live in the nasal organs of 

 TvLOPOUA (camels) and Cavicorxia (buffaloes), but Dr. Bau

 broader in front than behind ; mouth-hooks large, directed down- 

 wards ; between them is a small swelling; antenna) wide apart at 

 base, shortly conical, situated near tlie mouth-hooks, with an eye- 

 like, chitinous ring at tip. There are four semi-globular warts 

 above and near the antenna) ; similar, often indistinct warts 

 towards sides of segments. Seizments with a girdle of large, soft, 

 conical, thorny warts. Stignuitic jilates placed in a nari'ow depres- 

 sion of the last segment, Innate or kidney-shaped, with the false
