C celeripes Lee, Ann. Lye, 1848, iv, p. 183, pi. 14, fig. 14; Sdiaupp, I. c.

Brown-bronze, head and thorax greenish ; underside and legs green ; 

 tibiae and palpi pale, head granulate-rugose, eyes very large, labrum 

 large with one tooth ; thorax long, cylindrical, grooves faintly im- 

 pressed ; elytra coarsely punctate, punctures green at base, sparsely 

 clothed with short hair ; elytral markings variable, usually a discoidal 

 dot representing the tip of humeral lunule, another dot to represent 

 tip of middle band, a marginal line at the middle and an apical 

 lunule. In some specimens the last only is present. Interocular 

 strife fine and numerous; trochanters pale ; elytra broadest behind 

 the middle and broader in 9 than % , suture terminating in a small 

 spine more prominent in S . 



This species cannot fly and resembles a large ant when running. 

 It was taken abundantly by Prof. Popenoe in Riley Co., Kansas, on 

 open prairie land, dry sandy loam, covered with short cropped grass ; 

 also by Prof Wickham on the high clay hills back of Council Bluffs, 

 Iowa, in June and July, 1897, at noonday. The in.sects seemed to 

 make instinctively for the cover of the scattered grass clumps. Prof. 

 Bruner has sent me specimens taken in Nebraska, but I am not 

 advised of the exact locality.

Closely resembles the preceding ; differs in having the elytra less 

 deeply punctured and the sutural spine less prominent. The elytral 

 markings are broader than in celeripes and are confluent with the 

 broad marginal line which may reach only the apical two-thirds of 

 the elytra.
