and behind which there is a very short indistinct dark brown ciliation 

 of somewhat stout bristly hairs and behind that is a long (still short) 

 rather conspicuous yellowish fringe, the former one extending just 

 before the vertex and in that part its basement is 'rapidly broadened, 

 while the latter becomes sparser and less conspicuous about the upper 

 part. Proboscis slender and longer than the female but still shorter 

 than the depth of the head, brownish black, bearing abundant pale 

 yellowish white pubescence behind the stalk and furnished sparse short 

 brownish hairs on the underside of the sucker-flaps which are stout 

 and about half as long as the proboscis. Palpi very short and orange 

 yellow ; first joint short but cylindrical, slightly obscured by grey 

 tomentum on the outside, covered with abundant long (but much shorter 

 than that on jowls) yellowish pubescence ; second -joint less than twice 

 as long as the basal joint, slightly dilated apically, and then suddenly 

 narrowed to a large blunt point, covered with numerous comparatively 

 long yellowish pubescence which is intermixed with a very few scat- 

 tered shorter black hairs on the outside of the apical half, and at the 

 extreme top there are some dense very short black bristly hairs which 

 are mostly directed below. Antennae as in the female, but almost 

 usually paller. Eyes large, touching for about the middle five-seventh, 

 in view seen from the above triangular with outwardly curved out 

 margin, the hind margin about as long as the frontal margin and very 

 slightly curved inwards near the outer end ; in profile somewhat, 

 triangular, with very slightly outwardly curved frontal and facial margins 

 and convex hindmargin, and with the frontal angle about no° and 

 slightly rounded ; when seen from in front much deeper than the 

 width, the frontal angle wholly 145 , the lower angle about 100°, the 

 upper angle less than 8o°, and the outer angle evenly rounded ; facets 

 on about the upper two-thirds being all very much enlarged and 

 strongly contracted with the small facets on about the lower third and 

 on the narrower margin zone ; the enlarged facets extend undiminished 

 up to the touching part of the eyes ; the rather conspicuous line of
