but gradually becomes darker to brown, with a narrow pale yellowish 

 white actual-hind-marginal band on each segment ; pubescence mostly 

 greyish white but gradually becomes brownish behind, and on the disc 

 of the apical segment there are rather abundant long and erect brown- 

 ish black hairs which somewhat extend up to the preceding segment. 



Lenth : 9.5-1 1.3 mm. 



Described from four females in my collection from Kosempo in 

 the prefecture of Ako and from Tauran in the Shinchiku-prefecture in 

 Formosa. 



According to Ricardo's table this species falls in the Group III, 

 and it is allied to her unizonata from Ceylon, but is certainly distinct 

 from it, and from any other species belonging to that Group. The 

 wing-pattern has a great resemblance in general to that of singalensis 

 from Ceylon, and rather less to unizonata, and the greyish markings 

 on the thorax are more similar to the former species than to the latter, 

 while the antennae and legs are very closely allied to unizonata. 

 This handsome fly bites me severely on the back, through a thin shirt, 

 when I was sitting on the bridge across a stream near Kosempo in the 

 midday of a day in July. It was a very hot and brilliant day, 

 and its bite was very painful, and was irritable for about five consecutive 

 days. I noticed afterwards that the punctured spot remained visible 

 for about a fortnight. In the same month I caught a single fly, 

 which was resting on the belly of Formosan cattle.
