AMERICAN DERMAL MYIASIS 



etiology. — The following larvae are known to cause subcutaneous 

 myiasis in man: — ' 



(EstridcB : — 



Hypoderma bovis de Geer. 

 Hypoderma lineata deYilliers. 

 Hypoderma diana Brauer. 



Dermatohia cyaniventris Macquart, 1843; synonym, 



hominis (Linnaeus junior, 1781). 

 Dermatohia (?) kenicB Kolb. 

 (Estrus [C ephalomyia) ovis Linnaeus. 



MuscidcB (Subfamily Calliphorinae) : — 



Cordylohia anthropophaga E. Blanchard. 

 Cordylohia rodhaini. 



The life-history of the oestridae is curious, as will be discussed 

 below. With reference to Cordylohia anthropophaga, by a mistake 

 the cutaneous myiasis of Natal, Rhodesia, British Central Africa, 

 Uganda, and the Sudan, was assigned to Bengalia depressa, while it 

 should have been placed under this heading. 



Varieties. — As geographical distribution is important from the 

 point of view of the causal parasite, it appears to us to be convenient 

 to utilize this and to divide the subcutaneous myiases into the 

 American, the African, the Asian, and the European, while the last 

 variety is not geographical, but pathological — viz., creeping 

 eruption. 



American Dermal Myiasis. 



Synonym. — Neotropical dermal myiasis, Dermatobiasis. 

 ^^Deflnition. — Dermal myiasis as seen in Tropical America is 

 caused by the larva of Dermatohia hominis (Linnaeus junior, 178 1), 

 better known as Dermatohia cyaniventris Macquart, 1843, and 

 perhaps by other allied, but as yet unknown, forms. 



Nomenclature. — The fly which causes this myiasis has a large 

 number of scientific and popular names: —
