or shorter than the lower one, sharply pointed at the upper and lower 

 ends, very slightly elevated and longitudinally striolate, black but less 

 shining. Vertex dark but whitish grey behind, with numerous short 

 black pubescence and with a very inconspicuous brownish ocelligerous 

 tubercle which is sometimes wanted ; frontal triangle rather slightly 

 convex and comparatively narrow, almost wholly occupied by yellowish 

 shining subcallus leaving a narrow yellowish grey tomentose double 

 crescent just above the antennal fossae, the subcallus with a distinct 

 though very narrow and shallow longitudinal median sulcus through 

 the whole height. Face moderately convex as usual, covered with 

 whitish grey tomentum and white hairs ; epistoma large, quadrate with 

 rounded angles, as long as wide, with the rather small lateral pits, 

 covered with numerous long (but not very long) straight sloping white 

 pubescence which becomes slightly shorter above ; cheeks comparatively 

 narrow and the width in the broadest part less than the half of the 

 epistoma, the upper corner wholly covered with yellowish or brownish 

 grey tomentum which extends below to the middle part along the 

 eye-margin where there is almost only brown pubescence and the rest 

 of the cheeks covered with rather short white pubescence which grows 

 up longer about the jowls, and which hardly extends up to the back 

 of the head ; the back of the head covered with an ashy grey tomentum 

 and with some scattered short white pubescence, very shallow on the 

 lower part but distinctly (though not deep) hollowed out on the upper 

 part ; the postocular whitish bare rim rather broad and about equal in 

 width through the whole length but widened below near the jowls, 

 and behind this bare rim there is a black filiation of rather long but 

 not very dense hairs which becomes slightly shorter and paler below, 

 and which disappears on the jowls and does not extend on the vertex 

 behind which is some long black pubescence. Proboscis stout and 

 wholly two-thirds as long as the depth of the head, blackish brown, 

 slightly dusted with greyish, the stalk on the hind numerous long 

 white pubescence similar to that on the iowls, the sucker-flaps darker,
