CHAPTER XV 



CYCLORRHAPHA SCHIZOPHORA 



General description. All the members of this series are 

 distinguished by the presence of a distinct frontal lunula and 

 frontal suture. The antennae are composed of three segments 

 of which the terminal bears an arista, almost invariably dorsal 

 in position, and never thickened into a terminal style. There 

 are never more than three posterior cells present (Fig. 63) 

 the first of which may be closed or narrowed in the margin, 

 but the others remain open. None of the longitudinal veins 

 are forked ; the marginal and sub-marginal cells are never 

 closed ; and the anal cell very rarely extends towards the 

 margin of the wing. The flies are all more or less bristly. 



This very large division, including several families, is termed 

 by Williston, the Myodaria. It may be divided into two 

 groups, the Acalyptratae and Calyptratae, which are distinguished 

 as follows :
