Tribe II L ULOMINI. 



Elongate or oval, usually somewhat depressed species having the 

 head immersed in thorax to eyes, which are transverse and emargi- 

 nate; front dilated to cover the base of mandibles; antennie 11- 

 jointed, the outer joints more or less thickened ; middle coxa2 with- 

 out troehantin. hind coxa' slightly separated: tarsi pubescent be- 

 neath, the last joint much elongated. They live under bark, in 

 fungi or in dried vegetal)le products. Kepresentatives of but five 

 of the 36 genera have been taken in the ^Itate, though those of three 

 others perhaps occur.
