the remainder part there are soft whitish hairs all over the surface, 

 but about the back of the vertex with slightly longer conspicuous black 

 hairs. Proboscis brownish yellow, moderate in size and about two- 

 thirds as long as the deep of the head. Palpi whitish yellow, about 

 two-thirds as long as the proboscis ; first joint slightly darker, small, 

 somewhat elongated elliptical, about two-fifths as long as the second 

 joint, and bearing long whitish yellow hairs ; second joint long and 

 thin, drooping almost straight downwards and but little bent, moderately 

 inflated on the basal half and then tapering to almost a point, and 

 this joint bears a moderate number of short white adherent hairs on 

 the upper part and about the tip, and on the outside, but on the 

 underside (especially near the base) some longer pale yellowish white 

 hairs ; on the upper part of the second joint there are very few short 

 depressed black bristles which vary in number great deal. Antennae 

 pale reddish yellow or orange ; basal joint paler, thickened towards 

 the tip and its broadest part about as wide as long, bearing only a 

 few short black bristles on the upper side and some longer pale yellow 

 bristly hairs on the rest ; second joint very small, about half as long as 

 the basal joint, with a terminal circlet of short whitish glistening bristles 

 which are intermixed with very few longer black ones on the under- 

 side ; third joint more than twice as long as the two basal joints together,

conspicuously widened at the base and with an obvious fairly prominent 

 dorsal hump just before the middle of its basal annulation, and with one 

 or two inconspicuous minute black bristles on the hump ; style-like 

 portion of the third joint slightly darkened (especially at the tip), 

 apparently shorter than the basal annulation, and with its last articulation 

 long and narrowly conical. Eyes in death purplish black or yellowish 

 brown, bearing very short sparse pale pubescence, sometimes so slight 

 as to be almost imperceptible ; according to Prof. Matsumura showing 

 a narrow fuscous band which ends at the middle ot the eye ; eyes in 

 profile about as long as deep, frontal margin stightly curved forwards 

 and as long as the hind margin, the lower margin strongly curved
