705 (2099). QUEDIUS SPEL^US Horn, Trans. Amer. Ent. Soc., 1871. 332. 



Elongate, rather slender. Uniform pale red- 

 dish or chestnut brown, the elytra sometimes 

 a little darker. Head oval, longer than wide; 

 eyes small, slightly oblique. Antenna; reach- 

 ing base of thorax, the second joint less than 

 one-half the length of third. Thorax broader 

 than long, slightly narrowed in front, sides 

 feebly, base broadly curved; disk highly pol- 

 ished, with small punctures along the mar- 

 gins and base, in addition to the dorsal rows. 

 Elytra narrower than thorax, together as 

 wide as long; closely and rather coarsely and 

 roughly punctate, sparsely pubescent. Ab- 

 domen narrower than elytra, parallel. Length 

 10-14 mm. (Fig. 157.) 



.Monroe. Lawrence and Crawford counties; frequent locally in 

 caves. April 15-November 6. Occurs in decaying organic matter, 

 usually the excrement of raccoons and other cave visiting verte- 

 brates, or beneath stones in the vicinity thereof. Although Cope 

 and Packard both refer to this a.s a "twilight species," all speci- 

 mens lakcn were in tola! darkness, those in Wyandotte Cave being 

 1,0(10 i'cd I i-oin the mouth. As the temperature of the caves is very 

 much Hie same the year round the beetle probably breeds at all 

 seasons, as the larva* were always found with the adults.
