APIOCERID.E. 



189 



Therevidae, but seem best isolated into a distinct group, 

 though the relationships of Rhaphiomidas with the My- 

 daidge are evident; perhaps as close as with Apiocera. 

 The members of the genus Apiocera have much the ap- 

 pearance of large Therevidae or of Asilidae, from which 

 they will be at once distinguished by the anterior curva- 

 ture of the third and fourth veins of the wings. The 

 larvae are unknown. See fig. 70.
