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 Mie 



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 jiliation 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.
