the vertex, very narrow, contracting (but not conspicuously) from the 

 vertex to the frontal eye-angles, and about eight times as long as its 

 narrowest part or about six and a half times as long as its broadest 

 part ; frontal callus blackish brown or reddish brown, shining, slightly 

 convex, long and narrow, bearing an inconspicuous and intermixed 

 median sulcus, separated from the eye-margins by a comparatively 

 broad linear space and from the frontal triangle by a much broader 

 interval, but its upper end with a longer linear extension which reaches 

 above the middle of the frontal stripe and slightly keeled and sharply 

 pointed above ; vertex quite grey, with an indistinct very small eleva- 

 tion representing the ocelligerous tubercle ; frontal triangle covered with 

 a pale yellowish grey tomentum, slightly elevated from the eye-margins, 

 and with a fine median sulcus, separated from the cheeks by the 

 distinct and rather deep outwardly curved furrows which are not rea- 

 ching to the eye-margins but connecting with the short but conspicuous 

 sulcus along the eye-margins up and down the division between the 

 frontal triangle and cheeks, on both the sides of the median sulcus 

 with very faint ribs-like depressions. Face covered with pale yellowish 

 grey tomentum which becomes paler on the epistoma and on the lower 

 part, bearing a short scattered whitish pubescence with four or five black 

 hairs intermixed near the upper outer corners of the epistoma ; episto- 

 ma large, broader than the height, and its pubescence gradually growing 

 up rather shorter and more sloping towards the mouth-edge ; cheeks 

 narrower than half the width of the epistoma, conspicuously narrowed 

 above the lateral pits of the epistoma, rather conspicuously yellowish 

 about the upper corners, and the pubescence on the upper parts rather 

 shorter than that on the epistoma, but suddenly growing up much 

 longer and denser, and greyer about the jowls ; jowls moderately puffed 

 up from the eye-margin but not much extent, the pubescence very 

 slightly yellowish and extending up to the back of the head, where it 

 becomes much shorter, very much sparser though scattered on the 

 whole surface, and quite whitish ; l^ehind the narrow but broader than
