1. R. insitiva. 



Capsus insitivus Say, Hemipt. New Harm., 21, 8. 



No. 39-, Harris' Collection. "July, 1826." 



Determined by Mr. Say. 



This is a southern form, more particularly abundant south of Mary- 

 land. The present is the only specimen that I know to have been 

 obtained north of Pennsylvania. It is rare in this part of Maryland, 

 but less so in the districts belonging to the Carolinian fauna. 



2. R. eonfraterna, n. sp. 



Bright sanguineous, opaque, form of R. insitiva. Eyes, antennae, 

 circle upon the cranium, tylus and labrum black ; head across the 

 eyes much broader than apex of the pronotum, eyes round above and 

 prominent, front very convex and more elevated than in the preced- 

 ing species ; the antennae not so stout, clothed with fine, erect hairs, 

 the basal joint a little shorter than the anterior breadth of the pro- 

 notum ; the second joint twice as long as the basal one and a little 

 more slender, cylindrical, third joint still more slender, becoming 

 gradually more so towards the tip, fourth decreasingly slender and 

 about equal in length to the basal joint ; anterior lobe of the genae 

 extending a little beyond the middle of the tylus, triangular, rather 

 blunt at tip ; inferior lobe not quite reaching the apex of the tylus, 

 tipped with black; rostrum reaching the posterior coxae, more or less 

 piceous, the basal joint a little longer than the head, second joint a 

 little shorter than the fourth, third a little shorter than the second? 

 slightly swollen at base, fourth joint longest, stouter than the second 

 or third. Prothorax orange or red, longer than broad, regularly con- 

 vex on the disk, the collar broad, high, infuscated on the middle, the 

 incised line deep and entire, running continuously to the anterior 

 acetabulae, callosities high, transverse, black, coalescing on the middle 

 line ; on the middle a large, subtriangular black spot, extending from 

 the callosities to the basal margin; humeral angles bluntly rounded ,
