 Aslimead, H. H. Smith collection, Carnegie Museum. 



The types of S. trinidadensis and S. insularis Ashmead are slightly 

 smaller and more lightly colored than the typical S. 7nariae, but 

 otherwise they do not differ. Size and color differences alone are 

 not reliable specific differences in this genus.
