pubescent tibiae, broad frontal stripe which has two separated calli, and 

 prominent shining black subcallus. 



Female. Head prominently broader than the thorax, but very 

 short, and slightly arched. Frontal stripe broad, blackish but entirely 

 obscured by light tomentum which becomes yellowish brown round 

 the upper frontal callus and slightly contracting from the vertex to the 

 eye-angles, about three times as long as its broadest part or four times 

 as long as its narrowest part ; pubescence on the frontal stripe rather 

 sparse, very short and blackish, which does not extend at the interval 

 between the frontal calli and just above the subcallus, and which be- 

 comes slightly longer and denser towards the vertex ; lower frontal 

 callus brown to black shining, transversely quadrate not reaching the 

 eyes only leaving a very narrow greyish tomentose margin, and well 

 remote from the subcallus, very slightly elevated and irregularily 

 longitudinally striolate ; upper frontal callus slightly narrower but longer 

 than the first one, blackish but hardly shining, isolated, orbiculate but 

 sometimes cleft downwards and sometimes extending above to a point, 

 widely separated from the lower callus and well away from the eyes, 

 in the middle there is a distinct longitudinal ridge throughout the 

 whole length ; subcallus very large and conspicuously prominent, almost 

 all occupied the frontal triangle leaving a very narrow yellowish tomen- 

 tose double crescent just above the antennae, the median sulcus being 

 very faint ; vertex dark grey, parallel-sided, with a very inconspicuous 

 ocelligerous tubercle which is brownish and some times disappears, and 

 with rather abundant long (still short) blackish hairs. Face very broad, 

 with white tomentum and pubescence ; cheek rather broad, moderately 

 puffed up, covered with a white dust which becomes greyish brown at 

 the upper corner where the pubescence is blackish brown and shorter, 

 and the pubescence on the rest snowy white, dense, longer, and almost 

 erect ; epistoma slightly elevated from the cheeks, with deep lateral 

 pits, covered with denser, long snow-white pubescence which is sloping 

 below and straight ; jowls rather flat, thickly covered with longer shag-
