cell 1st Mo closed: male livpopygium Avith the long rostral prolonga- 

 tion of the ventral dististyle bispinoiis. 



Rostrum and palpi brownish black, the former a little brighter at 

 base in female. Head dark grayish brown, with a sparse yellow 

 pollen. 



Mesonotal praescutum gray laterally and on humeral region, more 

 brownish on disk, with a broad brownish black median stripe and 

 narrow, incomplete, lateral stripes; scutal lobes dark brown, the 

 median area with a yellow pollen; scutellum and mediotergite dark, 

 the former with a pale median stripe in front, the latter heavily 

 pruinose. Pleura pale yellowish gray to buffy, striped longitudinally 

 with darker brown, this including the entire ventral sternopleurite 

 and a more dorsal area on anepisternum. Halteres pale, the knobs 

 darkeneci. Legs very long and conspicuous; coxae and trochanters 

 obscure yellow; remainder of legs dark brown to brownish black, the 

 femoral bases narrowly obscure yellow. Wings long and narrow, 

 whitish subhyaline; bases of cells Ou, 1st A and 2n<:l A more infumed. 

 the color continued along vein Cu almost to m-cu\ veins dark, in the 

 prearcular, costal and subcostal fields, as well as basal half of M. pale. 

 Venation : So ending opposite origin of Rs ; cell 1st M2 closed, the 

 veins beyond it tending to diverge. 



Abdominal tergites brownish black, narrowly pale sublaterally : a 

 narrow black pleural stripe; sternites obscure yellow, more darkened 

 behind. Male hypopygium (Fig. 36, L) with the dististyle as in 

 lacroixi, the body of style larger and more produced; rostral pro- 

 longation dusky at apex, before midlength with two strongly curved 

 spines that arise close together. $ . L. about 6-7 mm. ; w. 6.5-8.2 mm.

Most nearly allied to lacroixi, as shown by the key. I dedicate 

 this interesting fly to the collector of the type, my friend, Mr. G. S. 

 Walley. His specimens were found associated Avith Phalacrocera 

 lipidina O. S., Lrmonia {Dicranomjjia) longipennis (Schumni.) and 

 other crane-flies. 



Subgenus Rhipidia Meigen 



1818. Rhipidia Meigen; Syst. Beschr. Zweifl. Ins.. 1 : 153. 



An abundant group, wide-spread throughout the major regions of 

 the Globe. In the local fauna, three divisions occur, separated on the 

 nature and degree of pectination of the antennae.
