Tropidosteptes. 



Form oval, rather broad, broadest across the posterior part of the 

 corium, abruptly deflected behind the line of the tips of the cunei. 

 Head broad, vertical, broad and blunt at tip, cranium very convex, 

 the occiput with a linear, transverse, entire carina connecting the 

 eyes; eyes small, oblique, laterally prominent, reniform, subacute at 

 the upper corner; cranial surface higher than the eyes, the front very 

 convex, each side near the eyes deeply impressed; the frontal bound- 

 ary impression sharply defined ; sutures bounding the tylus deep, the 

 tylus elongate-quadrilateral, with an impressed line upon each side ; 

 lateral superior lobe broad, convex, emarginated in front, the tip a 

 little rounded, and subtruncate, inferior lobe longer, convex, subelon- 

 gate-quadrate ; rostrum stout, reaching to the posterior coxae ; anten- 

 nae short, slender, basal joint almost bald, the second joint a little 

 more slender at base than tip, remotely pubescent. Pronotum about 

 one-half as long as broad, disk posteriorly very convex ; anterior 

 margin with a linear, much elevated carina, posterior margin broadly 

 rounded, lateral margins straight, acute; callosities prominent, trans- 

 verse; humeri elevated, the angles abruptly rounded; anterior angles 

 slightly rounded. Scutellum convex. Wings with no recurrent vein 

 in the costal areole. 



This genus is allied to Polymerus, but differs in having the head 

 thick and blunt at tip, with the corresponding modification of the 

 upper and lower cheek-lobes, the eyes smaller and not so prominent 

 anteriorly, the tylus less elongated, and more curved inwardly at 

 tip, and the lateral margin of the thorax straighter and more com- 

 plete.

Capsus cardinalis Say, MSS., determined by himself. 



Bright scarlet, polished, coarsely, deeply, confluently punctured. 

 Antennae, eyes, tylus, base of labrum, membrane, cunei along the 

 interior margin and behind the middle to the tip, also the adjacent 

 portion of the corium as far as the membrane, black. Head paler 

 red, smooth, polished ; with a few punctures in the depressions near 

 the eyes and antennae. Pronotum paler in front, very coarsely, deeply, 

 somewhat confluently punctured, the elevated lateral edge smooth, 

 impunctured, surface below the edge coarsely punctured. Under side 

 of head, sternal ends of coxae, basal joint of rostrum, middle line 

 of venter, and genital hook of male, yellow. Legs reddish black, or
