coarse punctures in basal third, these continued as two complete rows 

 paralleling claval suture and with a few finer ones scattered over 

 mesal half; exocorium with numerous finer punctures scattered ir- 

 regularly for full length; costa convex, with one setigerous puncture; 

 membranal suture feebly sinuate, lateral angle slightly produced; 

 membrane longer than basal width, reaching apex of abdomen. 



Propleuron : Shining, punctate only in depression and near acetabu- 

 lum; prosternal carinae about half as high as labial II, abruptly 

 terminated ventrally. 



Mesopleuron : Lateral area impunctate. 



Metapleuron: Peritreme terminated by small, triangular lobe which 

 is separated from gently concave lateral margin of evaporatorium by 

 space greater than width of terminal lobe (similar to fig. 97) ; lateral 

 area impunctate. 



Legs: Anterior tibia with five stout spines dorsally. 



Sternites: Shining, with few coarse punctures on lateral third near 

 posterior margin of each segment. 



Terminalia: Apical margin entire, straight; gonostylus as illustrated 

 (fig. 206). 



Length of body: 6.05. 



Type data.— Holo type male (MCZ), "Whitfield Hall, Blue Mts., 

 Hayti, near 4500 ft., Aug. 13-20, 1934, Darlington." 



Discussion.- — The trivial name is in allusion to the bronzed cast 

 that is visible on this species.
