rufous; lateral margin yellowish-rufous, with blackish incisure! 

 margins ; rostrum robust. 



Length over three-fifths of an inch. 



This insect was presented to me by Nuttall. It differs from 

 punctipes nob., inasmuch as that common species has the second 

 joint of the antennae shorter than the third; and ultimate 

 joints are black ; the punctures of the body also are [758] black, 

 the feet have black points and the rostrum is slender. The pre- 

 sent species is also larger. 



2 P. augur. — Thoracic spines pointing forward ; beneath 

 with five vittae. 



Inhabits Georgia. 



Body rather slender, attenuated from the thoracic spines to

 of impressed black punctures; antennae pale rufous; first joint 

 long oval; third joint longer than the second; thorax, spines 

 acute, pointing forwards ; punctures of the disc pale rufous, of 

 the lateral margin blackish; scutel and hemelytra, punctures 

 blackish : beneath with three or five vittas of black punctures ; 

 thighs with black points. 



Length two-fifths of an inch. 



In most respects this agrees with typhosus F., but it has no 

 sanguineous mark in the middle of the hemelytra. It was sent to 

 me by Mr. Oemler, of Savannah. 



3. P. emarginata — Bluish ; scutel with three fulvous dots. 



Inhabits Georgia. 



Body purplish blue ; rostrum pale fulvous ; thorax at posterior

 orbicular fulvous spots : feet at base pale fulvous : beneath, under 

 the rostrum, region of the feet, middle of the ventral base, anus, 

 and triangular lateral spot fulvous. 



Length half an inch. 



Female. — Thorax with the anterior and lateral margins and 

 longitudinal line in the middle dull fulvous; the two basal spots 

 of the scutel sometimes confluent.
