THE MYIASES AND ALLIED CONDITIONS 



Sarcophaga nura Rudolphi, by Mouchet at Katanga; Pycnosoma 

 putorum Wiedemann, 1830, in Abyssinia, Belgian Congo, and 

 Lorenzo Marques. The condition has been reproduced experi- 

 mentally in animals by Wellman, in 1906, with S. regularis Wiede- 

 mann in a goat. 



Definition. — Peenash is a word which may be used for the Indian 

 rhinal myiases caused by the larvae of species oi Pycnosoma Brauer 

 and von Bergenstamm, and by larvae of species of Sarcophaga 

 Meigen, especially by those of Sarcophaga carnaria Linnseus, 



Climatology. — The disease is spread throughout India and Assam. 

 Symptomatology. — As far as is known, the symptoms resemble 

 those produced hy other forms of rhinal myiasis. 

 Treatment. — This is the same as for other forms [vide supra) . 



These are known to be caused by Piophila casei and by species of 

 Sarcophaga Meigen, 1826, while Calliphora limea is also said to be 

 causal. 



Definition. — Aural myiasis is the invasion of the external auditory 

 meatus, the middle ear, and associated cavities, by the larvae of 

 certain dipterous flies, especially those of the Muscidae and Sarco- 

 phagidae. 



Historical. — Aural myiases have been recorded by Taschenberg 

 in 1870, Blake in 1872, Johnson in 1892, and Austen in 1912, but 

 the most complete stud3^ is that by Francaviglia in 1914.

 agents: —
