Family LATRIDIID/E. 
Very small, oval, convex insects with the thorax usually narrower than 
the elytra. They are very commonly brown in color, often striated, occa¬ 
sionally banded, and found commonly under bark, under decayed leaves 
and in sweeping among vegetation in early evening. The larvae are oval, 
soft, very hairy, and live in vegetable refuse, fungi, etc. Occasionally 
they are found in granaries, but never in really troublesome numbers. 
The arrangement here follows the revision of Prof. H. C. Fall in the
