{Crypioses cholccpi, n. gen. and sp.)

 in Ausland, for 1885, No. 31, page 617, speaks of this phe- 

 nomenon, referring to the moths as tineids. The matter is also 

 referred to in the Cambridge Natural History, Vol. vi, page 

 430, 1899, where it is stated that a species of Tinea has been 

 found in the hair of the living sloth, Bradypus cnculliger. 



Mr. August Busck, when recently in Panama, observed a 

 large sloth, Cholcepus hoffmanni, fall from a palm tree, the 

 leaves of which broke with its weight. When the animal fell 

 a number of small moths were dislodged by the shock and flew
