Family TROGOSITIDiE. 



Usually oblong, flat species, the prothorax as wide as the thorax and often 

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

 granaries, where they sometimes become rather numerous, though hardly 

 injurious. The measures already noted for other granary pests are also avail- 

 able here. A few seem to be parasitic in the larval stage.
