ing into each other, behind converging sUghtly to the hind margin; 

 with about four more or less distinct transverse keels between these 

 and with other transverse keels connecting the lateral keels to each 

 other and to the median pair; spiracles elongate-oval, almost elliptical. 



Wings. — Light fuliginous, with the usual transparent spots; vena- 

 tion typical; fore wing 7 mm., hind wing 4.75 mm. 



Legs. — Honey-yellow; trochanters more or less brownish; fore and 

 middle tarsal claws dark, cleft, hind tarsi wanting; no spines on 

 middle tibiae. 



Abdomen. — (From a single male specimen.) Elongate, length 3 

 mm., honey-yellow; smooth, shining, and with whitish hairs; first 

 segment rather stout. 



Redescribed from two specimens from Los Angeles, California, 

 probably collected by Coquillett. In one of the specimens the 

 structural character which I have used as distinctive is less pro- 

 nounced than in the other, and this, in connection with some other 

 more minute differences, leads to a little uncertainty as to the specific 

 agreement of the two specimens. However, I believe that part of the 

 difference may be accounted for by a difference in sex, although the 

 abdomen is wanting in one specimen, so it is not possible to be certain 

 of its sex. 



I have been unable to find out anything regarding the type of this 

 species. Presumably it was in the collection of the California 

 Academy of Sciences and was destroyed at the time of the San 

 Francisco earthquake and fire, so I have ventured to redescribe it, 

 designating the above specimens as neotypes and placing them 

 in the United States National Museum collection.
