Family XLV. CFPESIIXTv 



THE fVpEsin BEETLES. 



This small family is represented in the United States by but 

 two genera and live species of elongate and somewhat flattened 

 beetles, having the elytra entire, with rows of large square punc- 

 tures and intermediate ribs, and the hody covered with small 

 scales. They occur beneath bark and about old frame or log houses. 



The principal distinguishing characters of the family are the 

 11 -jointed filiform, rigid antenna 1 inserted rather close together
