only filling the basal cells about one-fifth of their length, continued 

 along the fore border to the apex ; the cross band not reaching be- 

 yond postical vein, the outer margin convex (but in Formosan speci- 

 mens quite straight or somewhat concave), extending from the apex 

 of the stigma to the lower angle of the discal cell, and the inner 

 margin convex, extending from the apex of the praefurca to the small 

 cross vein and usually continued with the brownish shade on the 

 lower branch of the postical fork along the basal portion of its upper 

 branch ; the extreme apex of the anal vein very rarely shaded ; the 

 centre of the discal cell hyaline ; the base of the submarginal cell 

 brownish hyaline ; the upper basal cell about the basal two-third the 

 length along the discal vein shaded with blackish brown ; brownish 

 colouring of the fore border at the apical portion narrow and 

 rather inconspicuous, hardly reaching to the apex of the wings ; 

 the postical cell distinctly open at the fourth posterior cell sometimes 

 slightly contracted at the margin of the wing ; upper branch of the 

 cubital fork without any trace of the recurrent veinlet near the base. 

 Squamae greyish yellow with yellow margins and with scarcely any 

 fringe, but the alar pair grey brown with yellowish fringe. Halteres 

 brown to blackish, with yellowish or reddish brown stalk. 



Legs reddish yellow and shining ; fore coxae at the basal 

 parts slightly covered with whitish tomentum, bearing rather sparse 

 and somewhat long whitish hairs ; all the trochanters, and the 

 middle- and hind-coxae brown ; femora furnished with rather fine but 

 not very short yellowish pubescence which is intermixed with a few 

 long brownish hairs at the outer surface of the fore femora and 

 especially is conspicuous towards the apex ; fore tibiae brownish 

 especially towards the apex, bearing with rather dense depressed short 

 brown pubescence with yellowish hairs .intermixed, but on the inner 

 surface mostly yellowish and much shorter ; middle tibiae usually 

 orange yellow with two short stout subequal blackish spurs, bearing 

 yellowish pubescence with a few brown one intermixed, but at the
