Oblong, convex species, surface of body dull and rough- 

 ened; living in dried decomposing animal matter; mandibles 

 and labrum prominent; epimera of the mesothorax widely 

 separated from the coxae by the sternum; abdomen with five 

 ventral segments, amply covered by the elytra; terminal seg- 

 ment of the tarsus without erect setae between the claws.

Trox Fabricius 



The species of this genus are all carrion feeders, prefer- 

 ring this material after it is well rotted and dried. Many of 

 the species are attracted in some numbers to lights at night. 

 Whether collected at lights or in carrion the specimens are 

 usually well encrusted with dirt and should be cleaned before 

 mounting. This is easily done by holding them under running 

 water and brushing with a camel's hair brush. It is highly 

 probable that a renewed study of the genus Trox employing 

 the characters to be found in the genitalia will somewhat 

 modify our present understanding of the species and varieties, 

 especially the latter.
