366 HETEROPTEROUS HEMIPTERA. 



Acad. Nat. Sci. Phil. 2d ser. 1, 58. It is found from Puget 

 Sound to Mexico, and from Maine to Florida, and thence to Bra- 

 zil. Dr. Leidy expresses the belief that it is ouly a variety of 

 B. grandis, in which opinion I entirely coincide. Stoll's figure 

 represents B. indicum, and should not have been cited for the 

 present species. — Uhler.] 



3. B. dilatata. — Dark grayish -brown, much dilated, ovate 

 somewhat depressed : head obsoletely varied with dull-yellowish : 

 thorax with the lateral margin very distinct ; anterior edge ob- 

 viously elevated ; impressed line of the posterior submargin well 

 defined, not abbreviated ; feet somewhat annulated ; venter tinged 

 with rufous. 



Inhabits Mexico. 



Length one inch and one-tenth. 



Resembles fluminea nob., but is much larger and proportionally 

 much more dilated. It was found between Vera Cruz and Jalapa 

 by Wm. Bennett and presented to me by Mr. Maclure. 



[This is the Paysan americain Stoll, Punaises, 11, pi. 1, fig. 1 ; 

 Amyot and Serville have given it the name of Stollei. It belongs 

 to Zaitha, and was described in Stanbury's Expedition to Great 

 Salt Lake as Z. bifoveata Hald. 370, pi. 10, fig. 1. It is also 

 figured by H. Schaffer (9, 292) as Z. Stollei— Uhler.]
