XLIX. — Notes on the smaller Genera of the Tabaiiiuae of the 

 Family Tabaxidjs in the British Museum Collection. By 

 Gektkude Kicaudo. 



TABANiy.E. 



The following table includes the genera comprised in the 

 second division ot" the Tabauidic, easily distinguished from 

 those of Pangoninie, the tirst division, by the absence of 

 spurs on the hind tibiae and of ocelli. The geuus Ditylomyia, 

 formed by Bigot, is not included, as the one species for 

 which he created it belongs to Gastroxides, an older genus; 

 Bigot's genus must therefore sink. As regards Dasybasis, a 

 genus formed by Macquart for an Australian species, I have 

 no knowledge of it, and its positign in the table is only 

 based on his description. 



One new genus is included, formed for a species from 

 Ceylon. Remarks on H(ematopota will follow later.
