high, transverse carina between the eyes; tylus a little prominent 

 narrowing towards the tip; cheeks short and blunt; bucculae nar- 

 row, shorter than the basal joint of the rostrum; that joint suIj- 

 cylindrical, robust, a little longer than the head. Antenna short, 

 about as long as the corium and cuneus united, stout; the third 

 and fourth joints of nearly equal thickness, not tapering to a 

 setaceous termination; the latter less than one-half the length of 

 the preceding. Pronotum trapezoidal; the angles rounded; the 

 collum forming an obtuse, narrow collar, and behind it is an 

 arcuated carina abbreviated a little way from the lateral margins; 

 the lateral edges prominently carinated. Costal margins of the 

 hemelytra almost straight, parallel. 



Hadronema was described by Uhler in 1872 in the Rep. of the 

 U. S. Geol. Survey, page 412. The genus now contains 7 species, 

 two of which are herein described as new.
