yellowish dust, the remaining part of the vertex slightly shining black- 

 ish ; pubescence on the irons very inconspicuous, pale yellowish, but 

 it becomes longer and darker towards the- vertex ; pubescence on the 

 occiput slight puffed out ; a double arched narrow band just above the 

 antennae orange yellow, slightly covered with a whitish yellow tomentum, 

 which extends completely round the antennae and for its full width to 

 the eyes, and is connected rather narrowly with the narrow whitish 

 yellow dusted middle part of the face ; this latter space points just 

 below the upper margin of the large shining pale reddish yellow united 

 oral callus, which is widely united with facial calli ; eye-margins very 

 narrowly yellowish grey and connected with broad yellowish band 

 which separates the facial from the buccal calli ; buccal calli rather 

 small and moderately shining black or yellowish brown, separated from 

 oral calli by an obscure but broad grey-dusted space. Pubescence on 

 the face mostly very fine, whitish, very sparse, but becomes a slightly 

 conspicuous towards the sides, a very few somewhat long sloping pale 

 yellow hairs conspicuous on the middle part of the face, and a few 

 long pale pubescence occuring on the jowls ; back of the head a little 

 puffed out, yellowish and bearing a very short orange yellow fringe 

 near but not on the eye margin. Antennae longer than the two-thirds 

 of the thorax, greyish yellow or pale yellowish brown, excepting of 

 about the apical two-thirds of the third joint blackish brown ; first joint 

 slightly stouter and longer than the second, furnished with rather 

 sparse short black pubescence ; second joint slightly darker than the 

 basal joint, with three very inconspicuous annulations and with somewhat 

 stouter and longer black hairs which become conspicuous towards the 

 apex ; third joint distinctly longer than the two basal joints together, 

 moderately upturned at the tip and with fairly conspicuous annulations 

 of which the first is slightly dilated near the base and is longer than 

 the remaining together, the basal annulation composed of four or five 

 inconspicuous annulations usually blackish at the apical half, the apical 

 annulation bearing a few very inconspicuous fine pubescence. Proboscis
