19.". 



ably longer than the basal two joints together and about the half as 

 wide as long, with a very blunt dorsal hump which is placed well 

 before the middle (rather near the base) and bearing two or three black- 

 ish setae ; style-like portion with four distinct annulations, very short 

 but slightly longer than half the length of the rest of the third joint, 

 its top-annulation pointed, brownish black and with two or three black- 

 ish bristles at the tip. Palpi dull pale yellow with outersicle rather 

 ashy grey, rather large ; second joint stout for about the basal half and 

 thence steadily contracting to a sharp point, about two and a half 

 times as long as its stoutest part, distinctly bent just before the middle, 

 and clothed with rather numerous short sloping white pubescence inter- 

 mixed with scattered depressed black bristles all over the upper and 

 outer parts except on the basal part ; first joint rather slender, slightly 

 longer than one-third the length of the second, dull yellowish, obscur- 

 ed by a greyish tomentum and clothed with rather long greyish hairs 

 all over the outer and lower parts. Proboscis brown, slightly longer 

 than the palpi. 



Thorax about as long as wide, conspicuously contracted towards 

 the front, covered with a yellowish grey tomentum, brownish but dis- 

 tinctly greyish at the front where there are three very inconspicuous 

 narrow stripes, in which the middle one extends behind the middle of 

 the disc, and its posterior thirds is separated into two lines by a dark 

 elongate-triangular intermediate space, while the outer ones only reach 

 to the suture where they obliquely turn inwards and connect with 

 the middle stripe ; at the side there is a broad but vague lateral stripe 

 which only extends on the praealar calli ; the surface of disc covered 

 with fairly abundant rather short not depressed fine brownish black 

 pubescence which is long and somewhat shaggy at the sides, and is 

 intermixed with a few golden yellow pubescence which is especially 

 conspicuous at the prae- and post-alar calli ; humeri rather small, slightly 

 reddish brown at the lower and hind margins, clothed with rather pale 

 pubescence ; praealar calli large, triangular, distinctly ashy grey, with
