yellowish grey, with a conspicuous median sulcus and a pair of very 

 faint oblique furrows, the latter being nearly parallel with the eye- 

 margin and very rarely crossed by two or three short ribs-like furrows. 

 Face similarily dusted with pale yellowish grey as the frontal triangle, 

 convex as usual, and with the rather deep conspicuous black lateral 

 pits, covered with abundant but not dense moderately long whitish 

 pubescence which is conspicuously numerous on the upper lateral corner 

 on the epistoma and on the cheeks, while the median part of the 

 former bears much sparser sloping hairs with a very few blackish pube- 

 scence intermixed ; jowls more inflated than the cheeks, covered with 

 dense conspicuously longer and shaggy whitish pubescence which hardly 

 extends up to the back of the head where there is a few scattered 

 short whitish pubescence ; the greyish bare postocular rim rather nar- 

 row, unequal in width throughout, very inconspicuously narrowed near 

 the vertex and rather distinctly narrowed about the outer eye-angle, 

 and behind which is a short yellowish brown ciliation which becomes 

 slightly longer and much paler on the upper part and extends below 

 to the hind upper part of the jowls. Proboscis stout and wholly two- 

 thirds as long as the depth of the head, blackish brown, covered with 

 abundant somewhat long whitish pubescence behind the stalk which 

 bears slightly longer yellowish tuft ; sucker-flaps large and about two- 

 thirds as long as the whole length of the proboscis, furnished with 

 some scattered short brown bristly hairs. Palpi dull yellow or pale 

 reddish yellow, long and slender ; first joint somewhat cylindrical, about 

 thirds as long as the second joint, obscured by dark grey tomentum 

 and covered with numerous long and shaggy pale yellowish white 

 pubescence similar to that on the jowls ; second joint narrow and about 

 four times as long as the width of the stout part, only moderately 

 dilated about the basal half but then drooping and gradually diminish- 

 ing to a blunt point, clothed with tiny black bristles all over the upper 

 and outer sides except the basal part at where there is a few longer thin 

 pale hairs especially on the underside. Antennae usually blackish with
