Members of this genus may be recognized by the possession of three 

 long veins, the cross vein running parallel or nearly so to costa in 

 connection with the forked fifth vein and the antennal segments in 

 both sexes being greatly produced. The males usually have 16, 

 rarely 15, antennal segments, the flagellate ones provided with a 

 long, and sometimes a very long stem. The females usually have 12 

 to 14 antennal segments, the stem one-fourth to one-third the length 

 of the basal enlargement. Kieffer has proposed to divide this group 

 into two subgenera, namely, Porricondyla s. str. comprising those 

 forms having the basal enlargement in the male antennae sub- 

 si >herical, while those of the female are more or less double or strongly 

 contracted in the middle in connection with the claws being strongly 

 curved and enlarged subapically; the other, Dicroneurus to include 

 those 1 species having the antennal segments cylindric in both sexes. 

 the daws arched and not enlarged subapically. lie has recently 

 proposed a more detailed classification of ibis genus, see page \^o. 

 The type pf the genus Porricondyla is Cccidomyia albi-
