I do not know the genus HQarimorpha and therefore can- 

 not say whether or not it is related to Mythicomyia, but I 

 think it probably is. As to the genus Mythicomyia, I agree 

 with Coquillctt in placing it in the Empididae. and with 

 Afelander in making it typical of a distinct subfamily. Its 

 affinity to the Bombyliid genera allied to Geron and Rhab- 

 dopsrphalus may be considered, but I cannot associate it with 

 the Ix'ptidae. 



I find the anal cell to be either closed or distinctly open, so 

 this character is of no family importance. The form of the 

 antennae and the venation, excq)t as to the anal cell, are con- 

 stant in the material examined. Taking these, as well as the 

 sum of the other characters, into consideration the genus sure- 

 ly favors the Empididae, and may be distinguished by the short 

 second vein ending in the first. 



On account of the dissimilarity be tw een the sexes, it is diffi- 

 cult to associate them in many cases, and it is possible that 

 some synoiiomy is created. This is, of course, unavoidable 

 with our present limited knowledge of the species. However, 

 synonomy is mud) preferable to misidentification.
