yellowish grey tomentose double crescent just above the antennal fossae 

 and a very narrow similarity dusted lateral margins which do not ex- 

 tend up to the upper angles and the subcallus with a distinct though 

 very narrow median longitudinal sulcus ; vertex dark without any trace of 

 the ocelligerous tubercle ; pubescence on the frontal stripe rather dense, 

 sloping, and black, but on the tomentose space above the lower 

 frontal callus paler and sparser and on the interval between the 

 subcallus and the callus practically wanted, the black pubescence being 

 slight!)' longer and much denser towards the vertex behind which some 

 erect black pubescence occurs. Face broad and moderately raised ; 

 epistoma densely covered with yellowish ashy tomentum and numerous 

 long straight sloping white pubescence, with deep but not large lateral 

 pits ; cheeks broad, the broadest part being wider than the half of the 

 epistoma which is broader than the length, covered with dense ashy 

 grey tomentum which becomes yellowish or yellowish brown on the upper 

 part, the coloured dust extending over or less half way bellow to the 

 jowls along the outer margin ; pubescence on the cheeks numerous and 

 erect, white on the ashy grey part, and brown on the yellowish part 

 especially on the upper-inner corner conspicuous, the white pubescence 

 becoming longer and shaggier on the jowls and extending a little up

 out on the upper part, covered with ashy grey tomentum and some 

 scattered whitish pubescence ; the postocular bare rim rather broad, 

 about equal in width throughout the whole length but slightly narrowed 

 near the vertex and moderately broadened near the jowls, and behind 

 this rim is rather long brownish black ciliation which shorter and 

 yellowish below to the jowls. Proboscis about two-third as long as 

 the depth of the head, stout, brownish black, the stalk with a long 

 dense white fringe behind ; the sucker-flaps darker, about two-third as
