coloring of the face but usually a little darker; median 

 carina slight, percurrent, a little less distinct on the prozona 

 than on the metazona. Prosternal spine rather large, ap- 

 pressed-cylindrical, very blunt, often mesially constricted a 

 little, feebly retrorse. Tegtnina almost invariably surpassing, 

 sometimes but slightly, more often considerably, the hind 

 femora, of moderate breadth, distinctly though very gradu- 

 ally tapering, bro wish fuscous, sometimes immaculate, some- 

 times sprinkled with fuscous dots of greater or less depth and 

 distinctness throughout the greater part of the discoidal area, 

 but rarely to any considerable extent or conspicuousness 

 beyond the middle; wingsmoderately broad, hyaline, glisten- 

 ing with fuscous veins and cross-veins darkest apically and 

 anteriorly. Thoracic pleura piceous or blackish fuscous, the 

 metathoracic episterna with a mesial streak of flavous of 

 greater or less clarity. Fore and middle femora distinctly 

 but not greatly tumid in the male; hind femora olivaceo- 

 testaceous, more or less heavily and ver^' variably obscured 

 or clouded with fuscous, the fuscous coloring generally con- 

 fined to the upper half, and above generally concentrated in 

 two fasciae, which sometimes extend partly in an oblique 

 direction on the outer face, but generally in a very obscure 



fashion, if at all, while the w^hole 

 under surface and at least the basal 

 half of the inner surface is more or 

 less impure flavous, sometimes 

 deepening, especialh^ beneath, to 

 ferruginous or even carmine; 

 hind tibiae normally red, sometimes
