of the cheek; this transverse spot is broadest at the eyereargin, gradual- 

 ly narrowed towards the other ends, and separated from the top blackish 

 spot by a narrow greyish white but very sparsely dotted with blackish 

 crescent ;. epistoma yellowish grey-white, broader than the side-cheek, 

 with a rather small roundish black pit on each side. Epistoma, cheeks, 

 jowls, etc., all clothed with a somewhat abundant but not very long 

 whitish (rather silvery) pubescence which becomes much longer and 

 much more conspicuous on the jowls ; just above the middle of epistoma 

 there is a row, composed of about six conspicuous long sloping curv- 

 ing blackish somewhat bristly hairs, and about the upper half of the 

 side-cheeks there is a few long blackish pubescence. Back of the head 

 yellowish grey on the distinct though very narrow postocular margin 

 and with a very short pale brownish yellow ciliation (just behind the 

 bare eye-rim) which becomes darker and slightly longer upwards and 

 which becomes inconspicuous and sparse behind the vertex ; the actual 

 back of the head ashy grey, hollowed out and almost entirely bare 

 from pubescence but about the lower quarter bearing a very sparse 

 short and fine whitish pubescence which merges into the long hairs on 

 the jowls. Proboscis longer than the depth of the head, moderately 

 stout, brownish black, with a slightly sloping rather long brown hairs 

 behind the stalk and with a .very few much more erect, a little stouter 

 blackish pubescence on the posterior surface of the sucker-flaps ; palpi 

 slender long but shorter than the proboscis, pale yellow but obscured 

 by a greyish white tomentum and with a slight brownish hue outside 

 the second joint, while the brownish hue is more pronounced under the 

 whitish dust of the basal joint ; palpi slightly curved, second joint dilat- 

 ed less than the basal two-thirds but broadest near the base, bearing 

 outside a fairly abundant black pubescence which becomes longer and 

 less sloping above, and there is a few rather inconspicuous pale grey- 

 ish pubescence behind and about the base, but which all the inside 

 bare ; basal joint bearing a rather long pale pubescence. Antennae 

 long and slender, brownish black with the basal joint reddish yellow oi
