Spluerodcrrud opima Lee., tibiie and tarsi reddish-brown, length 

 2.5 mm., occurs in lUinnis, North ( 'arolina and Texas. 



Subtribe B. (Ch^tocnemixi.) 



The members of this subtribe arc separated from the preceding 

 only by the closed cavities of the front coxcC. They are, for the 

 mcst part, very small oval or oblong species, with the upper surface 

 usually uniform in color. Although the two subtribes are each 

 probably represented in the State by about the same number of 

 genera, the present one lias much the fewer species.
