say’s ueteropterods hemiptera. 
ff Thorax unarmed with a spine. 
6. P. ligata, Dull olive green, external edge sanguineous. 
Inhab. Missouri. 
Body olive green, rather dull; confluently punctured : antennae 
black ; second joint rather longer than the third : thorax , late¬ 
ral margin sanguineous passing to yellowish on its inner side : 
scutel at tip bright sanguineous : hemelytra sanguineous on the 
lateral margin nearly to the middle, abdomen on the lateral 
margin from the middle to the tip sanguineous: beneath tinged

and black : beneath dusky, pale about the insertion of the feet; 
rostrum extending beyond the insertion of the posterior feet.

Aspect of P. annulata P. but widely distinct. It perhaps 
ought to be in the previous division of the genus inasmuch as 
the lateral thoracic angles are a little prominent; but they are 
obtusely rounded. Belongs to the genus Halys Fabr.
