not extend below to the jowls ; pubescence at the back of the mouth, 

 and on the jowls longer, paler, and rather shaggy ; the bare rim 

 under the eyes greyish white or greyish yellow ; back of the head 

 with a very narrow pale bare postocular rim which at the temple region 

 is practically sunk behind the eyes, and behind which is a very short 

 very inconspicuous brownish yellow ciliation which hardly grows longer 

 near the tip angle of the eyes and which has absolutely no long 

 overhanging or outstanding hairs, but in some lights the short ciliation 

 on the temple region is almost whitish and just near the vertex is a 

 few somewhat long brownish hairs ; vertex very small, and slightly 

 raised, hardly extending down between the eyes, brownish black or 

 greyish black and clothed with short erect blackish pubescence which 

 is not nearly long enough to constitute a tuft ; frontal triangle dull 

 yellow with the greyish brown upper point, and there is a distinct but 

 not well-defined narrow brownish black band interrupted at the middle 

 between the brownish and yellowish parts. Proboscis brownish black, 

 with the rather large sucker-flaps ; palpi pale yellow, dusted with 

 whitish, about three-fifth as long as the proboscis ; first joint nearly 

 cylindrical and about as the second joint, with a slight blackish grey 

 tinge except at the tip, and clothed with long thin pale yellowish hairs 

 which are intermixed with somewhat stouter blackish about the tip ; 

 .second joint elongate elliptical, more than twice as long as its thickest 

 part which is a little before its middle, and ending in a rather sudden 

 blunt conical or sometimes evenly rounded tip, and usually with a 

 slight compression beneath just before the tip,' widely clothed on its 

 upper part with long soft thin pale yellow pubescence of which there 

 is sometimes some indication on the underside, but the lower half of 

 the outside, sometimes all the underside, and all the tip with numerous 

 not short black stouter hairs. Antennae slightly narrower than in 

 the female ; the black bristles on the basal two joints much more con- 

 spicuous and longer ; the third joint (without the style-like portion) 

 about two and a half or three times longer than deep, the dorsal hump
