when seen from below, quite bare, when seen from front with large 

 obscure splashes about the eye-angles and with a slight darkening 

 between the antennae and eyes, extending up between the eyes where 

 it is rather blackish and is narrowly pointed, very slightly elevated 

 but slightly hollowed out between the eye-angles and with rather incoiv- 

 spicuous very fine longitudinal furrow ; face greyish yellow brown 

 with somewhat ashy hue, not elevated but rather hollowed excepting 

 the narrow side parts and the moderately produced jowls ; cheeks rather 

 broad, darker, and with an indefinite paler eyemargin extending from 

 the antennae down the sides cf the face right round until half-way up 

 the back of the head, and clothed with rather dense and rather long 

 black hairs which are bleached at their tips, and which extend right 

 round beneath the eyes but become rather shorter and stiffer as they 

 approach the lower part of the back of the head ; just the inner sides 

 of the cheeks with pale greyish yellow hairs which overhang the sunken 

 bare epistoma which is rather small and much greyish, and has the 

 rather large and somewhat deep lateral pit at the middle of the side- 

 margins ;. mouth margin rather narrowly and the back of the mouth 

 wholly and extensively clothed with longer shaggier yellowish grey 

 hairs, which extend up quite at the back of the head and mingle with 

 the similar pubescence on the prothorax, but the hollowed-out back 

 of the head bears some shorter thin greyish hairs ; the part beneath 

 the back of the eyes and up the lower third of the back of the head 

 only very slightly puffed out, while the upper two-thirds of the back 

 of the head are hollowed out behind the eyes ; the lower third of the 

 back of the head bearing a very short almost imperceptible black pos- 

 tocular ciliation, but above that a rather close more erect pale posto- 

 cular ciliation can be seen which is still very short for the middle 

 third, but which grows slightly longer though still short about the top 

 third, nor does it become perceptibly longer behind the vertex except 

 for a slight fringe at the actual corner of the eye ; vertex small, deeply 

 sunken, but almost entirely occupied by an oblong distinctly elevated
