the temple region) bare rim, behind which is a rather short though 

 rather crowded ciliation of yellowish brown hairs which extend to the 

 vertex ; back of the head light yellowish grey but becomes yellowish 

 brown upwards, and bearing some scattered blackish hairs. Proboscis 

 yellowish brown, wholly two-thirds as long as deep of the head, with 

 the rather long sucker-flaps which bear some erect brownish bristly 

 hairs on the underside, the stalk rather short and furnished with a 

 pale yellowish pubescence behind. Palpi dull pale yellowish, the second 

 joint almost obscured by short dense depressed black bristles amongst 

 which on the basal part (especially below) are some distinct whitish 

 soft hairs, the basal joint covered with numerous long somewhat shag- 

 gy whitish hairs, intermixed with a few black pubescence about the 

 apex ; palpi apparently shorter than the proboscis, rather slender, the 

 basal joint wholly one-third as long as the apical joint which is about 

 three and a half times as long as its thickest part, rather broad from 

 the base up to about the middle, after which they droop and gradual- 

 ly diminish to a narrow round-tip, quite bare on all the inner side but 

 with two or three longer pale hairs beneath about the base. Antennae 

 rather large, light reddish yellow ; the basal joint more dull yellowish, 

 about as long as broad, bearing numerous but rather sparse short 

 black bristly hairs which grow slightly longer about the broad apex 

 especially beneath ; second joint in colour the same as the basal joint, 

 about half as long as the first joint but not conspicuously narrower 

 than that; bearing a circlet of short black bristles around the .tip, 

 which are rather longer on the underside ; third joint less than three 

 times as long as the basal joints together, darkened at the tip, with a 

 very flat dorsal hump near the base ; basal articulation of the third 

 joint rather broad and short, less than twice as long as the style-like 

 portion, and about two and a half times as long as its broadest part ; 

 style-like portion rather large, with short conical apical articulation 

 which is slightly longer than the third articulation and which bears 

 some somewhat conspicuous but short black bristles at the tip. Eyes
