cf 9 . lyong. 8 — lo mm. 



Head. — Frons at level of anteniicne, one-third the width of the 

 head, narrowing at vertex to one- third of this width ( o* ) or about 

 half this width ( 9 ) ; blackish gre}', with short, soft black hairs. 

 Face with moderately long and thick white hair. Mouth border 

 very narrowly yellow ; ])roboscis dark brown, shining, hairy. 



Antennae black, with a little greyish white shimmer; first 

 two joints with black bristles, third bare, prolonged into the usual 

 style, which is pale at the tip, the pencil of hairs quite distinct. 

 Vertex of head with a distinct but short and deep indentation, 

 which is almost better described as a hole, from which a central 

 dark grey hairy protuberance arises, bearing the red ocelli, placed 

 closely together. 



Thora.x dark cinereous, the dorsum with sparse 3'ellowish 

 short hairs round the edges. Anterior part of thorax with a dense 

 fringe of very narrow long greyish white scales, intermixed behind 

 with long, soft, black hairs, these latter continuing more or less 

 over the whole dorsum, but rather shorter. 



Sides of thorax with gre^ash white long thick scaly pubes- 

 cence, thickest and most scaly below the humeral region ; thinner, 

 shorter and whiter posteriorly. It extends somewhat sparsely 

 above the insertion of the wings. Scutellum blackish cinere- 

 ous, covered with rather sparse but long soft black hairs and with 

 traces of a little short yellow hair around the whole scutellum. 

 A row of stiff hairs on posterior margin. Several strong black 

 spines below the edge of the dorsum anterior to insertion of 

 wing ; the posterior calli also, moderately conspicuous them- 

 selves, bear a few stiff long bristles. 



Abdomen blackish grey, 2nd segment distinctly but not 

 greatly longer than the five remaining ones. The whole dorsum 

 apparently covered with small yellowish white or quite white 

 scales, which may be thickest at the bases and posterior margins 

 of the segments. The whole surface is also covered lightly 

 with moderately long, soft, black hairs, and there is a bunch of 

 long whitish scaly pubescence at each side of the first segment. 

 This pubescence is continued along the sides of the abdomen. 

 Belly blackish, with short white hairs ; longer white pubescence 

 towards the base and the last segment (in the & only), with 

 rather closely placed, somewhat large and elongated snow-white 

 scales, which sometimes spread over the last two, or even three, 

 segments and extend round over the sides. 



In the 2 , these white scales below the aV^domen are absent, 

 and are replaced by long black hair on the ultimate segment. 

 The genital organs in the o» consist of a pair of stout upper 

 claspers (?), the apical half tapering to a blunt point, each 

 with a small lamella at the tip. This large organ is rufous 

 brown, a little blackish above at the base, and with some 

 reddish yellow hairs on the inner sides. Below fliese large 

 claspers are some further, apparently complex organs which 

 are not easily visible, the whole being protected by a large.
