Family TROGOSITID^E. 



Usually oblong, flat species, the prothorax as wide as the tho-rax and 

 often well separated from it. Generally they live under bark, but a few 

 live in granaries, where they sometimes become rather numerous, and 

 more rarely specimens are found on fungus. Some of them are predatory 

 or semi-parasitic in the larval stage, and very few are at all injurious.
