HETEROPTEROUS HEMIPTERA. 315 



I have found specimens in Pennsylvania and Florida. It is 

 larger than P. punctipes nob., and the lateral thoracic angles arc 

 prominent, but not angulated, as they are in that species. The 

 punctipes also is destitute of the black points at the lateral termi- 

 nations of the ventral incisures. [ 760 ] 



"j"j" Thorax unarmed with a spine. 



6. P. ligata. — Dull olive green, external edge sanguineous. 

 Inhabits Missouri. 



Body olive green, rather dull ; confluent!}' punctured : antennas 

 black; second joint rather longer than the third : thorax, lateral 

 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 with yellow 

 on the pectus : feet greenish, yellowish at base. 



Length eleven-twentieths of an inch. 



Presented to me by Nuttall as a native of Missouri. The edge 

 of the head is not reddish. 



[Is P. ru/ocinctum H. Schf, Wanz. Ins. 4, pi. 189, fig. 436. 

 Found in Missouri and Texas ; Dr. Fitch says, what I very much 

 doubt, that it occurs in New York. — Uhler.] 



7. P. laticornis. — Second joint of the antennas elongated, 

 compressed ; lateral margins of the thorax red. 



Inhabits United States. 



Body somewhat depressed ; marbled with fuscous and brown- 

 ish-cinereous; antennas second joint compressed and grooved, as 

 long as the anterior tibi; remaining joints; ; 



thorax on the lateral edge denticulate ; lateral margin rufous : 

 posterior angles a little prominent, rounded : hemelytra on the 

 lateral basal margin rufous : tergum, margin alternating with 

 rufous and black : beneath dusky, pale about the insertion of the 

 feet; rostrum extending beyond the insertion of the posterior 

 feet. 



Length seven-twentieths of an inch. 



Aspect of P. annulata F., 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.
