408 C. R. Osten Sacken: Synopsis oftlie described 



In using this table it must be borne in mind that of the eight 

 genera described, only two are known in both sexes {Blepharocera 

 and Liponeiira)\ four are known in the male sex only {Bibiocephala, 

 Agathon, Hammatorrhina and Hapalothrix); and that there is 

 some donbt, as will be shown below, about the sexes of Apistomyia 

 and Paltostoma. 



The thirteen species hitherto described are:

 rica and Mexico the following literature man be consulted. 



A species from Mexico is mentioned in my Cat. N. Am. Dipt. 

 1878, p. 17, which may be different from Schiner's species; some 

 details about it will be found in my paper on Blepharoceridae 

 (1. c. p. 411).
