Platycsyllidae 



This family includes but a single species, the Beaver Beetle, 

 which is permanently parasitic on the European and North 

 American beaver. As there are many beavers on the Island I

 examine the host.

P. castoris Kits. (2902). Record of capture lost. 



Sili'HIdae. The Carrion Beetles 



As they frequent carrion and decaying fungi, they are best 

 taken with meat traps. If the meat is placed in a small wide 

 mouthed bottle, wire netting put over the mouth, and the 

 bottle put in a jar in the ground, the beetles will be taken in 

 a clean condition.
