General form elongate, narrow, tapering gradually anteriorly and poster- 
iorly from the humeral spines which are sharply pointed and directed 
forward. General color pale yellow to greenish yellow. Head elongate, 
pale yellow, somewhat flattened above, the median lobe slightly longer than 
the lateral lobes which are recurved at outer margins and edged with 
black; two vittae of deep black punctures extend through ocelli from base 
to apex of head; extreme base of head smooth. Antennae pale rufous, 
the first segment shortest and a little paler than the others; third segment 
longer than second. Rostrum pale yellow with median line and most of 
apical segment black. Pronotum narrowing distinctly anteriorly, the pale 
antero-lateral edges roughened, the acute humeral angles pointing upward 
and forward; rufous punctuation of disk sparse and more or less irreg- 
ular, the punctures of the lateral margins dense and blackish. Scutellum 
long, coarsely, sparsely, irregularly punctate with black except tip and a 
more or less well defined median line; these are finely, sparsely punctate 
or entirely without punctures. Hemelytra greenish yellow, the punctua- 
tion black, finer and more sparsely arranged than on scutellum; costal 
margin and edge impunctate, pale yellow; exterior apical angle of corium 
with a black dot; membrane pale; tergum pale, the connexivum finely 
punctate, a litle yellower than costal margin of hemelytra, the posterior 
angles of the segments sharply pointed. Venter pale yellow to reddish 
yellow with three vittae of black punctures which are more or less well 
defined on ventral thoracic plates also. Spiracles large and black thus 
giving the appearance of five vittae on the abdomen. A black spot on 
each coxal enlargement, one on outer angle of mesosternal sclerite and 
one just behind the short extension of the ostiolar canal. A black wavy 
line on prostethus behind each eye. Legs pale yellow with black points, 
the claws and distal portion of the last tarsal segment a little infuscate. 
Length, 10.5-11.5 mm. Width between humeral spines, 4.5-5.5 mm. 
This pentatomid is very easily recognized among the others of 
our fauna by the elongate, narrow, linear form and by the long,
