S. macrocera Serra-Tosio, Serra-Tosio, 1971:277-280 (PI. 130 phallapo- 

 deme, gonostylus, and ta 3 ; p. 279 ecology). 



Sympotthastia sp. Saether 

 The two pupal exuviae (Saether 1969:34) were examined from Dr. 

 Saether's collection. This species differs from fulva by having only a few 

 anteriorly pointing spines on conjunctiva 11/ III. The lengths of these 

 specimens were about 5 mm instead of the 8 mm reported by Saether. 



Sympotthastia virendri (Singh) 

 This oriental species was placed in Sympotthastia by Sublette and 

 Sublette (1973). I am inclined to think this is not suitable, since Singh 

 (1958) described the species with hairy wings, pictured wing without 

 strong anal lobe, with acrostichals, and, in a diminutive drawing, the 

 SVo appears to be that possessed by the Diamesae. The number of 

 spermathecae was not mentioned for the female described. 



ACKNOWLEDGMENTS.— I thank the curators, Drs. Q. E. 

 Wheeler, Paul Clausen and W. W. Wirth, for their efforts that allowed 

 me to see important types, North Carolina's environmental biologists, 

 and Drs. Bruno Rossaro and L. C. V. Pinder who loaned me Palaearc- 

 tic examples. Special appreciation is extended to Dr. Bernard Serra- 

 Tosio for allowing me to reproduce his excellent figures (Figs. 7-12).
