the basal whorl much longer than the I'est ; terminal joint with a 

 slender projection ; pedicels not quite the length of the joints. 

 Hypostoma and front reddish-brown. Palpi long, thickly haired, 

 ochraceous-ferruginous ; first joint twice as long as the second ; 

 second and third joints thicker, of equal length ; last joint slender, 

 one-half longer than the second or third, curved. Thorax 

 reddish-ochraceous, nitidous ; two rows of white hairs from the 

 collare to the scutellum ; a few long erect white hairs in front of 

 the wings ; scutellum prominent, rounded-oblong, with a greyish 

 tint. Poisers niveous, with silvery white hairs ; club gradually 

 thickened. Abdomen acuminate, nitidous, cretaceous-white, with 

 a silvery white pubescence ; lamelte small, niveous, with tine 

 silvery white hairs. Legs moderately long, niveous, densely 

 clothed with very long semi-erect silvery white hairs ; a sooty- 

 black ring just before the tip of the femora, another at the tip of 

 the tibije, a third almost covering the first small tarsal joint, and 

 a broader and paler ring at the tips of the next three following 

 joints. Wings large, very densely covered with somewhat inter- 

 woven hairs surrounded by short dense cilia ; hairs and veins 

 niveous ; the costal vein with a sooty-black spot just before 

 the joining of the first longitudinal vein, the underlying portion 

 of the first and second and longitudinal veins and the whole of 

 cross-vein sooty-black, also a correspondingly broad but lighter 

 spot towards the tip of the third longitudinal vein ; surface of 

 wing with a pale bluish reflection, very faint on account of its 

 dense pubescence. First lougitudiual vein very wide of the

 vein considerably bent exteriorly after leaving the cross-vein, 

 reaching the miirgin nmcli beyond the apex of the wing ; cro.ss- 

 vein somewhat oblique, most distinct, situated a short distance 

 from the tip of the first longitudinal vein, and at a point more 

 than three-fourths of the length of the latter from the base ; third 

 longitudinal vein most distinct, starting a short distance from the 

 base of the second longitudinal vein, very little arcuated, reaching 

 the posterior border about half-way to the tip ; no trace of an 

 anterior branch. (Description drawn from fresh specimen).
