Discussion. — Although this form is treated here as a subspecies 

 because of the limited range (southeastern Texas) and great sunilarity 

 to the more common form within whose range it occurs, there is some 

 possibility that it may more properly be considered a full species. 

 It is an established form which, in spite of the very limited extent 

 of its range, is sympatric with another form, S. ductus cinctus. How- 

 ever, except for the color pattern of the corium, the two forms blend 

 in a clinal series that at present defies morphological separation. 

 Perhaps additional studies coupled with application of statistics will 

 show them as sibling species. Before this can be done reliably, 

 however, large series from several populations must be made available; 

 too many of the specimens at hand for both this and related forms 

 were single representations of collections. 



Garsaiiriinae, new subfamily 



Plate figures 65, 88, 169, 174 



Diagnosis. — The fact that tarsal II is distmctly thinner than either 



I or III, coupled with antennal II being much less than half as long 

 as antennal I, will set this subfamily apart from all others within the 

 family. The trichobothrial arrangement (fig. 174) and venational 

 pattern m the hind wing (fig. 169) are likewise each unique within 

 the family. 



Description. — ^Head: Length Httle more than half of width; an- 

 tennae 5-segmented; labium short, reachmg base of mesosternum, 



II without semicircular foliaceous lobe. 



Wings: Three widely spaced veins leaving apex of radial cell, 

 median vein with thick, wide, blunt process projecting into radial 

 cell at midlength (fig. 169).
