S $ . Bead bright orange ; proboscis and palpi orange or 

 orange-yellow with a little concolorous pubescence. Antennae 

 of male with thirteen joints, of female eleven ; in both sexes the 

 1st scapal joint is very large, approximately oblong, slightly curved 

 upwards, orange, sometimes with black streaks on the upper- 

 side and sometimes wholly reddish bro^^•n or brownish orange, 

 the 2nd scapal joint very small, easily overlooked, especially in the 

 male in which it is orange, whereas in the female it is always black. 

 In the male the 1st flagellar joint has a blunt projection on the 

 lower side, making the whole joint Y-shaped, black, with a pale 

 yellowish white tip ; it is unbranched. The remaining joints in 

 the male are cylindrical, elongate, the basal tv^o-thirds black or 

 blackish brown, the apical third pale yellowish ; each joint bears 

 two pairs of slender finger-like blackish brown branches which 

 droop downwards ; the first pair is situated at the base of the 

 joint, the second at the distal end of the black portion ; the 

 last joint is simple and much elongated. All the branches, and 

 in fact the whole antennae, are shortly pubescent. In the female 

 the flagellum is distinctly only of nine joints, the 1st longer than 

 the rest, broader at tlie tip, the 2nd rather similar though not so 

 long, the rest subannular, the apical joint conical. The whole 

 flagellum black, with short black pubescence. Thora,v wholly 

 bright orange, a little yellow just below the dorsum and sometimes 

 on the scutellum and metanotum. Abdomen yery xar'mhle ; bright 

 orange, with the bases of the segments more or less black ; 

 sometimes the greater portion of the dorsal surface blackish, 

 sometimes hardly any black colour present. Genitalia of male 

 orange, with blackish marks, these varying also ; in the female 

 shining black, often the last two or three segments black also. 

 Legs : coxae and femora bright orange, tips of latter broadly 

 black; tibiae and tarsi black or blackish, a moderately wide, 

 distinctly pale yellow or yellowish white band on the former at or 



* Both species are liable to variation in the wing-markings, but it is im- 

 possible to mistake one for the other if the descriptions of each are consiiUed. 

 t It is to be presumed Walker would have noticed the serration if present.
