Dc.scriptioti . — Dark brown to black, apex of second antennal segment and 
posterior connexival angle.s pale; membrane lilack, with irregular reticulate 
white markings; trochantiu's pale; tibiae with apical and subbasal, and 
femora with subapical pale rings; ventral surface brown, with lateral pale 
marks and light sjiiracles. 
Head very slightly longer than broad, slightly longer than pronotum; 
tylus rather broad, the sides parallel; impressions of vertex elongate, parallel; 
preocular tubercles olisolescent ; aiitenniferous spines moderately acute, 
slightly divergent, the lateral tooth slight or absent; postocular tubercles 
obsolescent; antennae (fig. 3c) moderately robust, somewhat shorter than 
head and pronotum together, the first segment extending lieyond middle of 
tylus, the second shorter than distance between eyes (22 to 25); rostrum 
reaching base of prosternum. Pronotum (tig. 3d) with lateral margins finely 
and irregularly denticulate, widely expanded, reliexed; carinac strongly 
elevated. Scutelliim longer than pronotum (45 to 30), elongate, triangular, 
sides strongly raised. Hemielytra extending (cf) to apical angles ol sixth 
abdominal segment, ( 9 ) to middle ot dorsal genital segment; corium almost 
or (piite to middle of fourth segment; exocorium moderately expanded at 
liase, mesocorium with one, endocorium without well developed transverse 
veins; connexivum broadly exposed. Abdomen oval, moderately eremite. 
d' (fig- 3b). Eifth ventral segment as long as sixth; genital segment mod- 
erately convex. Length, 7.5 to 8 mm.

emarginate at miildle. Length, ,8 to 1) mm. 
Type speciineiis (Missouri) lost. 
This is a coiiiiiion and widely distriluited siieeies of lai'g,e size, 
disfiiigtiished especially liy antennal and genitalic structure. An 
oeca.sional speeiinen exhibits incipient braehyptery, having the 
hemielytra about twice as long as the seutelhnn, venation dis- 
tinct, short hind wings present, and the joronotum a little de- 
pressed before base of seutelhnn. ^
