Section II. HARFALINA] UNISETOS.^. 



This section is much smaller thaii the preceding, the tribes num- 

 bering only a third and the genera proportionally less numerous. 

 The essential character is the presence of but (me bristle-l)earing 

 puncture above each eye. The seta at or near the hind angle of 

 iliorax is more often absent than present. Of the eight tribes, but 

 three are rejiresented in the Indiana fauna. These may be distin- 

 guislied as follows : 



KEY TO INDIANA TKIBIiS OF HAKPALIN,-E UNISETOS.i:. 



a. Elytra truncate at apex; mandibles witb a bristle-bearing puncture in 

 outer groove; bind cox;e often separated, tbe tirst ventral segment 

 visible between them ; epimera of mesosternum usually wide, some- 

 times nearly as large as episteruii. Tribe I. Brachynini, p. 15lJ. 

 a. Elytra always entire; mandibles without a bristle-bearing puncture; 

 hind cox:e contiguous; epimera of mesosternum very narrow and iu- 

 distiuct. 

 h. Antenna' with three basal joints glabrous; elytral margin more or 

 less interrupted and with an internal fold; front tarsi of male with 

 three, rarely four, joints si)ongy pubescent beneath.

 brous; elyti-al margin not internyited, no internal fold; male tarsi 

 variable. Tribe III. Harpalini, p, 173,
