Discussion. — Several authors have listed conditions of capture for 

 their specimens, as follows: Van Duzee (1894, p. 169), "Swept from 

 weeds in low, swampy meadow"; Torre Bueno (1915, p. 277) "in 

 beach drift"; Parshley (1923, p. 780), "sometimes found under stones 

 in spring, after hibernation in the adult condition"; Hendrickson 

 (1930, p. 66), "At Andropogon furcatus consocies"; Blatchley (1926, 

 p. 87), "by sweeping herbage or sifting debris in low, moist grounds." 

 Two of the specimens examined bore the field notes, "under drift" 

 and "from soil."

Diagnosis. — Among those species with five jugal pegs and length 

 less than 2.5, the present species may be recognized by the vertical 

 anterior edges of the prosternal carinae (fig. 38) and the immaculate 

 coria. 



Description. — Color: Head, pronotum, scutellum and venter red- 

 dish brown; coria yellowish, immaculate; labium and legs yellow.

 interocular width, 0.32(0.30-0.34); clj^peus slightly surpassing apices 

 of juga; latter with five marginal pegs becoming smaller toward eye; 

 surface with coarse punctures between eyes. Antennal segments; 

 I, 0.11(0.10-0.13); n, 0.03(0.03-0.04); HI, 0.27(0.23-0.30); IV, 

 0.25(0.23-0.27); V, 0.30(0.29-0.31). Labium attaining middle of
