gy snowy white hairs which slightly extend up to the back of the 

 head but become rapidly shorter there ; postocular margin with a 

 comparatively broad whitish bare rim which is about equal in width 

 about the upper two-thirds but the lower third is narrower and gradual- 

 ly tapering below the jowls, behind this bare rim is a rather sparse 

 blackish ciliation which becomes gradually shorter from the upper eye- 

 angle to the jowls and behind that a more abundant whitish ciliation 

 which gradually grows a little longer though sparser all over the back 

 of the head which is very slightly hollowed out about the upper half; 

 behind the vertex are some conspicuous longer blackish hairs which 

 are slightly lapping over the vertex. Proboscis stout and short, hardly 

 two-thirds as long as the depth of the head, blackish, with dense 

 long white pubescence behind the stalk, and the sucker-flaps much 

 more longer than half the length of the proboscis, furnished with some 

 short blackish bristly hairs below. Palpi slightly shorter than the 

 proboscis, rather stout ; first joint brownish, slightly obscured by a 

 greyish tomentum, oval, covered with dense long white hairs which 

 are similar to those on the jowls ; second joint on the outside brownish 

 with tip yellowish, but obscured by a whitish tomentum, on the inner 

 side yellowish throughout, the pubescence on the outside short (but 

 about the basal half longer) numerous but not dense, snowy white, 

 and with rather abundant more shorter depressed black bristly hairs 

 intermixed, while on the inner side there is no conspicuous pubescence; 

 this second joint rather stout, and short, broad about the basal half 

 but then drooping and gradually tapper! ng to a point, about three times 

 as long as its broadest part. Antennae rather slender, but about as 

 long as the palpi, tawny or pale reddish brown two basal joints pale 

 yellowish ; first joint comparatively large and stout, gradually thickened 

 towards the apex where is broader than the broadest part of the third 

 joint, dorsally pointed very cap-like over the second joint, this process 

 being usually black ; the basal joint covered with a whitish grey tomea- 

 tum, and with numerous black bristles above, while the lower surface
