The genus Parodinia is closely allied to Zagonia Coquillett, 

 and possibly could be ranked as synonymous with it, but with 

 our very limited knowledge of this family I do not consider 

 it advisable to sink the latter at present. The only difference 

 between them lies in the much higher cheeks of Zagonia, 

 which has the height of cheek at least equal to that of eye, 

 whereas Parodinia has the eye very distinctly higher than 

 the height of cheek. In Agromyzinae I do not consider this 

 character as of more than specific value, but I apprehend no 

 disadvantages from the retention of the genus Zagonia.

Parodinia cinerea Coquillett. 



Syn.: Parodinia cinerea Coquillett, Jour. N. Y. Ent. Soc., Vol. 10, 

 1902, p. 186. 



This species may be known from its allies by the black third 

 antennal joint, the cheeks being about half as high as eye, 

 and the legs being entirely yellow, except the tarsi, which 

 are browned. This species, which is the type of the genus, 

 was described by Coquillett from three specimens, taken by 

 himself, at Los Angeles, California.
