Through the kindness of Prof. Bruner I have before me the type of 

 this species, a 9 from Sapucay, Paraguay. From the material in 

 hand it appears that this species has several color forms, as in brunneri 

 and other species. The type has the dorsal surface of the head and 

 pronotum uniform wood brown without cruciform markings or longi- 

 tudinal median stripe, and a majority of the females and several of the 

 males examined belong to this type. Several males and females have 

 the dorsum dark with weak, but distinct, cruciform pronotal markings 

 and a longitudinal light bar of variable prominence, in some cases 

 absent. In about half the specimens the heavy blackish markings 

 on the lateral lobes of the pronotum and caudad and ventrad of the 

 eyes are distinct, while the dorsal bars of the caudal femora are dis- 

 tinct in the greater number, weak and interrupted in several others 

 mcluding the type, dorso-lateral carina of the femora marked ventrad 

 with blackish in all specimens, very distinct in some, broken and 

 faint in others, the genicular lobes also blackish.

These specimens have been compared with typical individuals 

 kindly loaned by Prof. Bruner. This species is very richly colored 

 and one of the more easily recognized forms, the distinct femoral bars 

 and the entirely black genicular region being quite striking in all the 

 specimens examined. Considerable superficial resemblance exists to 

 *S. conspersa, which is found in the same locality, but the angle of the
