Section II. HARPALIN.J) UfilSETOSM. 



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

 bering only a third and the genera proportionally less numerous. 

 The essential character is the presence of but one bristle-bearing 

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

 thorax is more often alisent than present. Of the eight tribes, but 

 three are rej)reseiited in the Indiana fauna. These may be distin- 

 guished as follows : 



KEY TO INDIANA TRIBES OF HABPALIN^ UNISETOS.E. 



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

 outer groove; hind coxie often separated, the first ventral seitment 

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

 times nearly as large as episterna. Tribe I. Brachynini, p. l.jii. 

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

 hind coxa; contiguous ; epimera of mesosternum very narrow and in- 

 distinct. 

 6. Antenna' with three liasal .ioints glabrous; elytral margin more or 

 less interrupted and with an internal fold ; front t.nrsi of male with 

 three, rarely four, joints sjiongy pubescent beneath. 



Tribe II. Chl^niini, p. Itili. 

 Vb. Antennae with two, rarely {TachiiccHux) with three, basal joints gla- 

 brous : elytr.nl margin not interrupted, no internal fold ; male tarsi 

 varialile. Tribe III. Habpalini, p. 17o. 



Tribe I. BRACHYNINI. 



Antenna=^ slender, the condyle of the basal joint exposed, two 

 basal and a i)()rtion of the third .joint glabroijs. Head gradually 

 nari'owed behind the eyes into a neck; labrum broad, truncate; 

 mandibles stout, feebly curved, witii a seta in outer groove; men- 

 lum moderately broad, emai'ginate, toothed or not; the second joint 

 of palpi longer than the last. Thorax with short marginal setii';
