The five following species are probably South American ; they are 

 described in the Annuario del Museo Zoologica (ii. 68 — 69), by Prof. 

 Costa, who does not mention where they dwell : — multinotata, 

 strigosa, capitulata, quinquesignata, lobata. 



Arabia. 

 pensilis, Klug. 



Hindostan and Ceylon, 

 uigrorufa, Wlk. providens, Motsch. elougatula, Mutsch. 



Australia, 

 delicatula, Wlk. 



In S. pensilis and in S. leucotelus the apical part of the female 

 abdomen is cylindrical and very slender, like that of the two species 

 of Cbalcis before mentioned. 



Numerous groups and series of species may be formed of the 

 South American Smicrse by noticing the various length of the petiole, 

 by tracing the gradual change of structure in the abdominal segments 

 of the female, and by observing the many " colorational patterns " of the 

 body and the shading of one kind of markings into another. Their 

 chief habitation is the Amazon region, where it is probable that 

 there are very many species yet unknown, and there is a large field 

 for investigation in the discovery of new species and in studying their 

 geographical distribution before they and their prey are diminished 

 by the cultivation of the land. They are comparatively scarce in 

 North America, where the British S. nigrifex dwells with some 

 other kinds that have more resemblauce to the South American 

 forms.
