hyaline but somewhat infuscate and very often tinged with yellowish 

 along the veins, with the veins dark brown but usually yellowish brown 

 on the basal parts of the radial, cubital, and postical veins,* and with 

 the stigma yellowish brown ; both the first posterior and anal cells 

 closed with a rather long petiole, but in some specimens from Taihoku 

 the former widely open, and discal cell moderate in size and slightly 

 longer than the second posterior cell ; the upper branch of the cubital 

 fork without the recurrent veinlet but very rarely with its indication. 

 Squamae in the alar pair glassy grey with a brownish black margin 

 and a dense conspicuous dark brown ciliation excepting for a long 

 (but not very long) deep orange yellow tuft about the angle, in the 

 thoracal pair yellowish brown with a dark brown margin and a brown 

 ciliation of fine pubescence which is slightly longer and sparser than 

 that in the alar pair. Halteres yellowish brown but the knob dark 

 brown with the apex yellow. 



Legs blackish, with the extreme apices of the femora, and with 

 the basal two-third of the front tibiae and the posterior two pairs of 

 the tibiae except at their apices, yellowish ; front coxae dilated and 

 about two-thirds as long as the front femora, densely covered with an 

 ashy grey tomentum and with long whitish grey pubescence which 

 becomes conspicuously shorter towards the apex; front femora dusted 

 with grey excepting of the broad shining black subfemoral bare space 

 which is inconspicuously transversely striolate and grooved about the 

 apical half, and at the inner margin of this bare space is short and 

 stout very conspicuous black ciliation ; pubescence on the front femora 

 mostly very short and black on the inner surface, and long and pale 

 yellowish grey (with a silvery shimmer in a certain light) on the outer 

 surface where there is a very few stout black hairs about the apices 

 and sometimes is one or two conspicuous black bristly hairs about the 

 middle, on the posterior two pairs covered with pale yellowish ashy 

 grey tomentum almost all over the surface and clothed with numerous 

 whitish (with a silvery shimmer in a certain light) pubescence which
