always more yellowish than the jowls, behind which is a conspicuous 

 yellowish brown dilation which is usually intermixed with some thick 

 blackish hairs about the temple region or sometimes from the upper 

 ends to the jowls. Proboscis rather stout and short, about two-thirds 

 as long as the depth of the head, dull brownish black ; the stalk- 

 usually obscured by some yellowish grey tomeiitum, and bearing some 

 yellowish pubescence behind and with more or less brownish somewhat 

 bristly hairs at the sides ; sucker-Haps large and longer than the stalk, 

 furnished beneath with comparatively long scattered brownish black 

 bristly hairs intermixed with a few shorter yellowish white hairs. 

 Palpi in the end joint luteous but varying to dull brownish yellow, 

 usually almost obscured by short dense depressed black bristles amongst 

 which on the basal part (especially above) or sometimes throughout 

 the outer surface are some less distinct thin smaller yellowish bristles 

 intermixed, but sometimes the numerous short black bristles are almost 

 confined to the apical (or rarely basal) two-thirds and occur only very 

 sparsely before or rarely after the middle, while the basal part (or 

 nearly apex) has only the smaller thin inconspicuous yellowish bristles ; 

 the second joint of the palpi nearly five times as long as their broadest 

 part, somewhat broad from the base up to about the middle, after which 

 they droop and gradually diminish to a moderate point or a round tip, 

 quite bare on all the innerside but with a few longer pale hairs beneath 

 about the base ; basal joint narrow wholly four times as long as the 

 end joint, usually darker than the first joint, covered with long nume- 

 rous soft yellowish hairs. Antennae slender and long, reddish yellow 

 with two basal joints pale orange yellow and with the tip dark brown ; 

 basal joint covered with numerous comparatively long black bristly 

 hairs on the upper and outer side, but on the innerside some incon- 

 spicuous pale hairs which are very rarely intermixed with a few black 

 bristles and near the apex of the underside a few long blackish 

 pubescence, moderately thickened at the end and about one and a half 

 times as long as its broadest part, extending somewhat cap-like over
