Section II. HARP ALINES UNISETOS^E. 



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 absent than present. Of the eight tribes, but 

 three are represented in the Indiana fauiui. These may be distin- 

 guished as follows : 



KEY TO INDIANA TRIBES OF HARPALIN^ UNISETOS.E. 



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

 outer groove ; hind coxte often separated, the first ventral segment 

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

 times nearly as large as episterna. Tribe I. BRACHYNINI, p. 156. 

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

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

 distinct. 



It. Antennae 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 spongy pubescent beneath. 



Tribe II. CHL^NIINI, p. 162. 



/>'/. Antennae with two, rarely (Tachycellus) with three, basal joints gla- 

 brous; elytral margin not interrupted, no internal fold; male tarsi 

 variable. Tribe III. HARPALINI, p. 173. 



Tribe I. BRACHYNINI. 



Antenna- slender, the condyle of the basal joint exposed, two 

 basal and a portion of the third joint glabrous. Head gradually 

 narrowed behind the eyes into a neck; labrum broad, truncate; 

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

 Inm moderately broad, emarginate, toothed or not; the second joint 

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