16. S. annulipes (End. 1912). 



Pycnocrepis annulipes. End. (Feb. 1912). 

 Styringomyia howardi, Alex, (March 1912). 



Figs. 28, 29, 68 and 69. 



Closely resembles S. sjdstedti except in the genitalia. 

 I have previously (1912) mentioned S. howardi as a synonym 

 of S. crassicosta; this assumption was made on purely a 

 priori grounds, and an examination of the type of S. howardi 

 has since proved it to be incorrect.
