tphydride or Geomyzide. Mik refers it to the Ephydride and 
Loew to the Agromyzide; all of which views render it clear that 
the definition of these families is not very exact. Through the 
kindness of Mrs. Slosson I have recently had the opportunity to ex- 
amine the type species of Lipochaeta Coq. Its habitus is very foreign 
to the Ephydride and its union with it will require the abandonment 
of the families Oscinide and Agromyzida. No Ephydrid that I 
know of lacks bristles, while both of these latter families have 
numerous forms without them. The face is too short, the antennae 
too different in structure to belong with the Ephydridew. More- 
over the pollinose body and white wings, while, not absent 
among Ephydride, are not at all common. All these characters, 
however, are found in species related to Leucopis, Cryptochetum, 
Rhicnoessa, etc. Ifit is a representative of a new sub-family, at least 
half a dozen other genera, like Cryptochetum, Canace, Aulacigaster, 
Diastata, Letomyza, etc. will require the same treatment. I prefer 
to place it among the Ochthiphiline in the vicinity of AAzcnoessa. 
[ts relation with Z/fara can not be overlooked. 
I may add to the description that the anal cell is incomplete, the 
costa ig continued to the tip of the fourth vein, and the last abdomi- 
nal segment (? female) is conical and elongated; the first vein does 
not reach the middle of the wing, the third and fourth veins are 
gently convergent; the second vein is long; and the ocelli are not 
remote from the vertical margin, as figured.

the descriptions.

Numerous specimens from Brazil agree well with the characters 
given for this genus by Becker, and it seems probable that the spe- 
cies is identical with the one he had.
