HAIll OF LAUVA OF DEEMESTES. 217 



The Dermestes lardarius is "a small black beetle, very 

 destructive to bacon ; it has a broad gray band, spotted 

 black at the base of the elytra. It belongs to the Pen- 

 tamera, having five joints in the tarsi, and to the Clavicornes, 

 having clubbed antennae. The larvae are most mischievous 

 in insect collections. So, also, another of the family An- 

 threnus, whose hairs are mounted as test objects. 



We find the larvae of Anthrenus under the bark of old 

 elm-trees in February; of light brown colour, with tufts 

 of long hairs on the three lower joints of the abdomen. 

 These hairs are wonderfully beautiful. Soak them a few 

 minutes in turpentine, and mount in balsam.
