A few genera which have not found their final resting place in the 

 present systems of classification are discussed in the following notes. 

 The first five of these genera are not included in the table of genera, 

 the other three are. 



Aulacigaster Macquart, which has been variously assigned to 

 the Agromyzinae, Geomyzinje, Drosophilinae and Ephydrin^e. has the 

 second basal cell confluent with the discal, the anal cell well-formed, 

 the auxiliary vein relatively distinct and entirely separate from 

 the first vein, the costa broken at the humeral crossvein and again 

 at the auxiliary vein, the clypeus very large, the center of the 

 face continuing laterally under the bucc^e so as to comprise a large 

 part of the cheeks, the anterior fronto-orbitals proclinate and the 

 postverticals convergent. This combination of characters clearly 

 places it in the Drosophilinas notwithstanding its bare arista. The 

 West Indian species figured by Williston in his Manual, page 292, 

 agrees with rufitarsis except that the auxiliary vein ends in the first 

 in Williston's figure and the arista is pubescent. 



Cyrtonotum Macquart has the costa twice broken. The struc- 

 ture of the orbital bristles, the face, cheeks and mouth is also like that 

 of the Drosophilinae. 



Leiomyza Macquart was reported by Williston, Entomological 

 News, vii, page 185, from America, but no species was described. 

 Becker places this genus with Aulacigaster in the Drosophilinae. I 

 have no specimens and so have no opinion to offer. 



Lipochaeta Coquillett, which Williston once referred to the Och- 

 thiphiliuK, has the costa twice broken. It is a curious Ephydrid. 



Sephanilla Rondani, described from Italy in 1874 and not since 

 reported, was placed by its author with Lcucopis and Ochthi- 

 phila. It is, however, a shining black species, the front with a trans- 

 verse yellow band above the antennae, the mouth-parts, . antennae, 

 halteres and legs in part light-colored. The lack of pruinosity, the 

 basal position of the crossveins and the course of the auxiliary vein 

 would indicate a Geomyzid or perhaps a Sapromyzid. It is not suffi- 

 ciently characterized to find a place in the table. 



Pseudopomyza Strobl, located by the author in the Drosophi- 

 linne or Geomyzinae, is placed by Hendel close to Desmonietopa.
