hairs almost disappear ; jowls moderately puffed out below the eye, 

 covered with numerous long snowy-white hairs which extend slightly 

 up to the back of the head which is slightly hollowed out and ashy 

 grey ; back of the eyes with a narrow bare whitish postocular rim, 

 which is about equal in width throughout its length, but widens a 

 little when quite close to the upper eye-angles and contracts at the 

 enter of jowl, and behind that with . a short (though comparatively 

 long) stubby ciliation which is paler and shorter still below but which 

 becomes black right up to but not beyond the upper eye-angles, be- 

 hind the vertex are some longer black hairs. Proboscis short and 

 stout, about two-thirds as long as the depth of the head, blackish 

 brown ; the stalk with abundant long erect yellowish pubescence in- 

 . termixed with stout blackish bristly hairs ; the sucker-flaps large, dark- 

 er, about two-thirds as long as whole the length of the proboscis, 

 furnished with a few scattered short blackish bristles below. Palpi 

 light whitish yellow, stout, about as long as the proboscis ; basal joint 

 brownish grey, oval, densely covered with long snowy white pubescence 

 similar to that on the jowls ; second joint slightly darker outwards, 

 long though thickened for nearly the basal half but tapering gradually 

 after that to a point, rather rooping and about two and a half times 

 as long as its thickest part, bearing numerous though not dense short 

 depressed black bristles all over the upper and outer side, but some- 

 times with these black bristles less numerous on about the basal third, 

 and with a few shining white hairs intermixed, and this second joint 

 bears beneath about its base some longer snowy white pubescence, but 

 is bare on its inner side. Antennae slender but about as long as 

 the palpi, yellow ochre ; basal joint short and stout, extending dorsal- 

 ly moderately cap-like over the second, covered with whitish tomentum 

 and numerous black bristles which do not extend be!ow to the 

 underside where there is a few pale hairs ; second joint very small, 

 about half as long as the basal joint, with a narrow spine-like tiny 

 process at the dcrsal apex, and with a somewhat complete circlet of
