from the eyes (often touching them) and from the black callus ; still 

 higher up right on the middle of the grey part of the frons is a small 

 black spot or dot which is very rarely wanted. The black parts of the 

 frons bare, but the greyish part bearing moderate rather inconspicuous 

 sloping pubescence which appears mostly pale and rather conspicuously 

 so just above and below the dull black lateral spot, but is to a large 

 extent black on all the middle part and the black one extends up. to 

 the occiput. Face yellowish ashy grey or greyish white, widening out 

 rapidly under the eyes, and the cheeks at the lower half and jowls of 

 almost equal width almost as far as the back of the eyes, though the jowl 

 part retracts rather flatly and is almost half as wide as the depth of the 

 eyes ; the upper half of the cheeks dotted with black spots which hardly 

 coalesce and are more conspicuous towards the eye-margin ; epistoma 

 pale greyish with a small black spot on each side to the cheeks in 

 addition to the black pit on each side lower down, the pubescence on 

 the epistoma fairly abundant, rather long, and whitish, which becomes 

 more scarce and shorter above. Pubescence on the cheeks similar 

 to that on the epistoma but the somewhat shorter and also scarcer 

 towards its upper margin ; the pubescence on the jowls much longer 

 and much denser, and not actually expanded up to the back of the 

 head. Back of the head dark ashy grey and hollowed out, but yellowish 

 grey or whitish grey on a distinct though narrow postocular margin 

 and with a short dense rather yellowish ciliation (just behind the bare 

 eye-rim) which does not become any longer on the upper part and 

 which becomes inconspicuous and sparse behind the vertex. Antennae 

 about one and a half times as long as the head ; two basal joints black, 

 but mainly covered with a grey tomentum which leaves only almost 

 the apical one-thirds of the first joint shining black on the upper side 

 and a little more at the lateral sides ; first joint moderately dilated for 

 a somewhat considerable length about the middle and apparently three 

 times as long as its broadest part, bearing small black bristle all over 

 and with some thin pale hairs beneath on the basal two-thirds ; second
