S 2 . Head with frons (slightly narrower in o than 2 ) and 

 face dark mouse-brown or blackish, with black hairs on upper 

 part of former, and the same, mixed with thin scale-like yellow 

 hairs, on rest of frons and on face; frons in 2 only a little 

 narrower at vertex than above antennae, where it is distinctly less 

 than one-third the width of the head; face sometimes a little 

 l^eddish at margins ; mouth-opening from reddish brown to pale 

 brownish yellow ; proboscis dark brown ; antennas black or nearly 

 so, sometimes tinged with dark reddish brown ; remainder of head 

 as in H.jlaviventris. Thorax black, with black pubescence, 

 adorned with orange scaly pubescence and bristles as in H.jlavi- 

 ventris ; scutellum black, posterior half more or less reddish 

 brown, vestiture as in H.jlaviventris. Abdomen black, with black 

 pubescence ; a bunch of long orange-yellow scales at sides of 

 2nd segment, and from thence to the tip the sides with coarse 

 black bristly hairs ; 3rd segment with a transverse band as in 

 H.jlaviventris, but the colour of the scales graduates from yellow 

 {in the median line) to white (towards the margins of the 

 segment) ; the 6th and 7th segments each bear a pair of white or 

 yellowish-white scale spots, which are more remote from each 

 other than in H. chrysolampis and nearer the edges of the abdomen. 

 in the S the whole dorsum of the 5th, 6th, and 7th segments is 

 covered with silvery-white scales. Venter black, 2nd and 3rd 

 segments covered nearly to the side-margins with small whitish 

 scales, and these scales continued in the median line only on the 

 next two segments ; over the four segments is a median stripe of 

 fine long white hairs ; genitalia apparently as in other species, 

 placed completely sideways in J . Legs very dark brown, almost 

 black, vestiture as in allied species. Wings in $ nearly clear, 

 with the dark oblique band with a less well-defined margin than 

 in H.jlaviventris, running irregularly from tip of 1st longitudinal 

 vein, passing well beyond anterior cross-vein to anal angle of 

 wing, thus filling the inner submarginal cell and the 2nd basal 

 cell, and half filling the discal, anal, and axillary cells ; 2nd 

 posterior cell about as wide at base as at tip. In one specimen 

 the brown band fades away more gradually and extends further 

 posteriorly. In the 3 the binder limit of the dark colour is 

 practically straight, the discal half (diagonally) of the marginal 

 cell is clear, as is also the 1st submarginal cell, except at its base ; 

 the clear part of the wing is more hyaline in the <5 . 



Length, 13-15 mm.
