grows longer (but still short) about the middle upper mouth-edge ; back 



f 

 of the head moderately hollowed out, yellowish ashy grey leaving a 



very narrow ashy grey postocular rim behind which is an inconspicuous 

 short pale yellow pubescence ; the slightly longer hairs about the 

 back of the vertex mainly blackish ; jowls slightly puffed out below 

 the eyes. Proboscis brownish black, about as long as the depth of the 

 head, the stalk bearing a few sparse short blackish pubescence behind 

 and the sucker-flaps bearing more few very much sparser longer (but 

 still short) erect stouter pubescence below. Palpi pale yellow, about 

 three-fourths the length of the proboscis ; second joint long and thin, 

 drooping almost straight downwards and but little curved, moderately 

 inflated on the basal half and then tapering to almost a point, and 

 this joint bears moderate number of short black adherent bristles on 

 the frontal part through the whole length (except for the extreme base), 

 but outside mainly only similar but pale yellowish bristles, and on the 

 posterior side especially near the base some long pale yellow hairs ; 

 basal joint pale yellow and furnished with rather abundant long pale 

 yellowish pubescence. Antennae pale reddish yellow, with basal joint 

 whitish yellow, about three-fourths the length of the head ; first joint about 

 three times of the second joint, bearing dorsally near the tip only short 

 black bristles which very often extend slightly on the outside, and 

 furnished with a very few long (still short) pale yellowish white pu- 

 bescence below near the tip ; second joint with scarcely more than an 

 apical circlet of tiny bristles ; third joint shorter than the three-times 

 of the two basal joints together ; the basal annulation of the third joint 

 very much dilated and compressed, apparently longer than the style, 

 the dorsal hump near the base with a very few minute black bristles 

 on its tip ; the style slightly darker with a pointed apical annulation 

 which is an elongate conical and is distinctly longer than the preceding 

 anuulations. Eyes bearing very sparse microscopical pale pubescence, 

 sometimes so slight as to be almost imperceptible ; eyes in profile shorter 

 than its depth, with a very conspicuously downwardly curved lower margin.
