FAMILY XT. STAPHT'LINIDJE. 



dd. Head arid ineso- and meta sterna piceous. 803. caeolinum. 



go. Abdomen uniform pale reddish-brown ; head darker than thorax and 

 elytra ; length 8.5-11 mm. pimerianum. 



*S01 (2484). Geyptobium badium Grav., Mon. Col. Micr., 1806, 53. 



Uniform reddish-brown, shining, the head slightly darker. Head ob- 

 long-oval, sides nearly parallel, coarsely and rather closely punctate, the 

 front smooth. Thorax much narrower than head, one-fourth longer than 

 wide, sides feebly curved; disk sparsely, coarsely and shallowly punctate, 

 with a median smooth space. Elytra one-third longer and nearly one-half 

 wider than thorax, coarsely, rather closely and irregularly punctate. Ab- 

 domen rather finely, not densely punctate. Length 10-12.5 mm. 



Southern half of State, common ; much less so in the northern 

 counties. February 10-November 17. Occurs beneath bark and 

 hibernates in small colonies beneath partly buried logs. About one- 

 third of the males have the third ventral prolonged backwards in a 

 lobe, with parallel sides and rounded tip. This bears a fringe of 

 long, stiff hairs and sometimes reaches nearly to the end of abdo- 

 men. (Fig. 162, No. 1.) This lobe is also present in some of the 

 males of the next two species, but its function is as yet unknown. 



*802 (2490). Ceyptobium bicoloe Grav., Mon. Col. Micr., 1806, 179. 



Head black ; labrum, antenna-, thorax, elytra and last two segments of 

 abdomen pale reddish-brown ; legs pale yellow. Head oblong-oval, coarsely, 

 not densely punctate. Thorax narrower than head, one-fourth longer than 

 wide, sides parallel; disk smooth at middle, coarsely and rather closely 

 punctate on sides. Elytra one-third wider and longer than thorax, rather 

 coarsely, closely and irregularly punctate. Abdomen slightly narrower than 

 elytra, sparsely and finely punctate. Males of two forms, one with, the 

 other without, a prolongation of third ventral. Length 7.5-10 mm. 



Throughout the State; common. January 5-October 28. Oc- 

 curs beneath cover and on fungi, especially in wooded pasture land. 

 Hibernates beneath mullein leaves, logs, etc. 



C. texanum Lee, 8-11 mm. in length, has been recorded from 

 near Cincinnati, though its range is usually given as Texas to New 

 Mexico. 



803 (2491). Ceyptobium caeoltnum Erichs., Gen. Spec. Staph., 1840, 563. 



Piceous, moderately shining; thorax, elytra and last two abdominal 

 segments rather dark reddish-brown; antennae brownish, two basal joints 

 and legs dull yellow. Head broadly oval, as wide as or wider than (male) 

 elytra, coarsely and rather sparsely punctate. Thorax as in Mcolor. Ely- 

 tra one-fourth wider and one-third longer than thorax, very coarsely, closely 

 and roughly punctate. Abdomen as wide as elytra, coarsely and rather 

 sparsely punctate. Males as in badium. Length 8.5-10.5 mm. 



Kosciusko, Marion. Knox and Posey counties; scarce. March 

 21-June 22. Occurs on fungi and carrion. The females are easily
