(with a slight silvery shimmer) pubescence which becomes conspicuously 

 numerous and longer about the jowls and extends up a little to the 

 back of the head ; back of the head moderately hollowed out, ashy 

 grey tomentose and covered with some scattered white pubescence 

 which is apparently longer than that on the epistoma, with an equal 

 narrow ashy grey postocular rim behind which is a short but rather 

 conspicuous dark brown ciliation and behind that with a more cons- 

 picuous and longer pale yellowish fringe which becomes much longer 

 and more outstanding on the upper part, though the interval between 

 the eyes at the back of the vertex bears only a few longer pale hairs. 

 Proboscis short and stout, less than two-thirds of the depth of the 

 head, blackish brown, covered with short and erect whitish pubescence 

 behind the stalk ; the sucker-flaps large and about three-fourth as 

 long as the proboscis, furnished with very short scattered brownish 

 hairs beneath and with some longer blackish brown hairs intermixed. 

 Palpi long and slender, hardly reaching the end of the proboscis, 

 pale yellowish ; basal joint oblong and about one-fourth as long as the 

 end joint, slightly covered with greyish or sometimes dark greyish 

 tomentum, and clothed with long (but shorter than that on the jowls) 

 pale yellowish grey pubescence ; second joint very long and slender, 

 but stout about the basal third and than drooping and gradually 

 tapering to a rather sharp point, about three and a half times as long 

 as its thickest part, obscured by numerous dense short depressed 

 black pubescence on the outside excepting of the base where there are 

 some short inconspicuous whitish hairs especially on the underside. 

 Antennae usually reddish yellow but sometimes reddish black or red- 

 dish brown ; basal joint cylindrical though short, inconspicuously 

 thickened at the apex where it has a broad rather short expansion, 

 slightly covered with a greyish tomentum, the upper side bearing tiny 

 black pubescence which more or less extends below the innerside near 

 the top, and fine but longer whitish hairs on the lower half; second 

 joint sir all, and about one-thirds as long as the basal joint, .usually
