This fannly embodies in North Amei'ica about 100 known species 

 of brownish beetles without spots, which li\'e, tor tlie most part, be- 

 neath bai-k' or on Howci-s and leaves. In form tln'y are usually elon- 

 gate-oval, ([uite convex, and clothed above with minute hairs wdiich 

 give a silken gloss to the surface. Although closely allied to the 

 Tenebrionida-, they arc readily s('i)arated by the coni])-like or pec-
