Genus ANASTGECHUS, O.-S. 



Ajmstwchxs, Osten-Sacken, 'Western Diptera,' p. 2ol (1877). 



Gknotype, Bomhylitts niiidtilvs, E. (as hccrhatifs, O.-S.) (Europe); 

 by original designation. 



This genus differs From Bomhijlius by both basal cells being of 

 equal length. The dense furry pubescence of the underside of the 

 head distinguishes it from 8ysfaich\<s (which also has the basal 

 cells subequal in length), but not from Bomhylius.

Only one Oriental species has been recorded.
