which extends at the occiput. Face greyish yellow, on the cheeks 

 there is rather sparse, short, whitish yellow pubescence which becomes 

 longer and denser all over the jowls, while the epistoma almost is bare 

 though on the upper and side parts there is very inconspicuous short 

 pubescence ; jowls moderately broad and puffed out below, yellow ish 

 grey, and with a bare greyish white postocular rim extending from 

 them up to the top corners of the eyes, and this rim contracting from 

 the jowls to the vertex ; immediately behind this postocular rim a 

 short brown dilation exists which slightly increases in width from the 

 upper to lower part, but so slightly that it is not visible when the 

 head is viewed from in front ; this ciliation not merged into the curved 

 black hairs on the occiput ; back of the head slightly hollowed out, 

 yellowish grey, with rather a few scattered pale pubescence which becomes 

 somewhat conspicuous below to the jowls. Proboscis not very stout, 

 about two-thirds as long as the depth of the head, pale brown, its stalk 

 bearing somewhat long, erect, yellowish hairs behind, the sucker-flaps 

 about half as long as the proboscis, and bearing rather sparse rather 

 short yellowish pubescence beneath, palpi slender dull yellow, slights- 

 shorter than the antennae ; basal joint narrow, cylindrical, about one- 

 thirds as long as the second joint, slightly greyish at the outside, 

 Dealing abundant long pale yellowish hairs which only extend about 

 the outside and lower surface, and which are intermixed with a few 

 black bristly hairs about the apex; second joint fairly stout for about 

 the basal half and thence steadily contracting to a sharp point, about 

 four times as long as its thickest part, and clothed with numerous 

 short depressed black bristles all over the upper and outer parts except 

 just the base, and with a few thin pale hairs beneath the basal half 

 intermixed, and at the inner side there are a . few scattered similar 

 bristles about the apical thirds. Antennae more or less brownish red 

 with the style-like portion blackish, but the two basal somewhat greyish 

 orange ; basal joint on the upper part with dense short black bristles 

 which somewhat extend below to the side: parts except the narrow
