HETEROPTEROUS HEMIPTERA. 359 



line : posterior portion pale ; hemelytra hardly longer than the 

 anterior portion of the body. 



Length to tip of hemelytra seven-tenths of an inch. 



This insect was sent to me by Mr. Barabino. It closely re- 

 sembles our common species represented in the Am. Entom . 

 vol. 3, pi. 47, but is much smaller, and the feet have no appear- 

 ance of annulations. 



3. [2] P. ERRABUNDA. — This is so closely allied to P. vaga- 

 bunda Fabr., that I give it a distinct name with much hesitation ; 

 nevertheless the anterior thighs are somewhat less elongated, with 

 the two basal spines much more prominent than the others j the 

 abdomen is immaculate, the annulations of the feet are much 

 more obvious ; the lateral carinate line of the thorax has a pro- 

 minence like an obtuse spine before : in these characters it differs 

 from the vagahunda : but in the spotted appearance of the heme- 

 lytra and the form and magnitude of the scutellar spines it re- 

 sembles that species.
