whitish on about the median longitudinal line especially about the base ;. 

 sucker-flaps large and wholly two-thirds as long as the whole length 

 of the proboscis, darker, and bearing very few shorter and very sparse 

 brownish bristly though rather fine hairs beneath. Palpi short and 

 somewhat cylindrical with the apex thickened, pale yellow or dull 

 yellow ; basal joint greyish with some darker tinge on the outside, 

 rather long and cylindrical, about two-thirds as long as the end joint, 

 covered with numerous long pale yellowish grey or whitish pubescence; 

 second joint thickened about the apical half and about twice as long as 

 its thickest part, with a rather rounded blunt top and covered with 

 shorter whitish pubescence which becomes much shorter and yellowish 

 about the tip on where there are some rather conspicuous short black 

 bristly hairs which sometimes extend behind to the middle along the 

 outer-lower side. Antennae almost as in the female but more yellow- 

 ish with the style-like portion distinctly blackish, which is more slender 

 and longer and its apical ambulation being wholly twice or about three 

 times as long as the preceding annulation, each of the three basal an- 

 nulations of the style usually longer than the width. Eyes large, 

 conspicuously broader than the thorax but shorter, bare from pubescence ; 

 when seen from above triangular with the hind margin slightly concave 

 and with the outer margin usually convex, and the frontal margin 

 slightly longer than or almost as long as the hind margin ; in profile 

 conspicuously deeper than the length, irregular triangular with the 

 longest posterior margin strongly curved outwards, the frontal margin 

 next in length and very slightly convex, forming about 95 ? but rounded 

 angle with the shortest facial margin which is very slightly curved at 

 both the ends, and the lower angle about 90° and largely rounded ; 

 when seen from front about two-thirds as wide as the depth, with the 

 frontal margin a little shorter than or about as long as the facial margin 

 which is nearly straight and forming a lower angle about iOO" but 

 rounded, the frontal angle about 150° and the outer margin very 

 strongly convex especially at the lower half; facets on about the upper
