XenolisjHi mirubU'is (Stein). 



This i)oculiar species is refcral)lc to XenuUspa. It has the 

 vertical bristles weaker than in atrifruntata, but like that 

 species it has the outer pair very weak and small. The 

 parafacials are bare or almost so, the arista very short-haired. 

 There are three fuscous vittie on thorax, the ])reseutellar 

 pair of dorso-centrals are very small ami weak, the sterno- 

 pleural is strong, and the stigmatal bristle is hair-like and 

 short ; seutellar bristles short, the a[)ex of scutellum with a 

 j'ark spot, liasal tergitc with a pair of contiguous s|)ots at 

 base, tlic other tergites each with a pair of curved fuscous 

 spots. Legs slender, blackish, with grey j)ruincsccnce, the 

 tibiie tawny ; mid-til)ia with the postero-dorsal bristle and 

 hirul tibia with the antero-dorsal bristle weak. Fore femur 

 with only fine hairs ventrally. 



Stein describes the male as having the fore tarsus whitish, 

 and broadened as in many species of the Syrpliid genus 

 Pliitychirus, and the hind tibia with a fringe of fine hairs. 

 1 have seen oidy the female, which has the fore tarsus short 

 but of normal lorm, and the hind tibia without a fringe.
