hyaline, the apex slightly darker, iridescent, the nervures and 

 stigma black. $ . 



Length 17 mm. 



Cape Colony. (Brak Kloof) ; Transvaal. 



Face and clypeus closely, strongly punctured ; the apex of the 

 clypeus transverse, smooth, slightly raised ; the labruni more coarsely 

 punctured and with a large tuft of long pale hair in the centre. 

 Ocellar region smooth and shining, the rest of the vertex and front 

 shagreened. Pro- and meso-thorax closely, strongly punctured ; the 

 metanotum coarsely shagreened. The hair on the basal segment of 

 the abdomen is long and white ; on the second to fourth depressed, 

 short, brighter and paler on the apices of the segments ; on the 

 penultimate segment it is much longer and fulvous. The anal rima 

 coarsely shagreened. The mandibles are black at the base, the apex 

 broadly cream-coloured. The hair on the legs is very long and 

 dense ; on the outer side of the hinder tarsi is a shield-shape plate, 

 broad at the base, becoming roundly narrowed towards the apex and 

 covered with depressed fulvous pubescence. 



I only know the female of this species. I am not sure but that 

 Macrocera capensis, Lep., may be its male. My species is a true 

 Habropoda. 



PLESIANTHIDIUM, gen. nov. 



Similar to Anthidium, but with the maxillary palpi 3-jointed and 

 the mandibles unidentate. 



This genus is founded on a large species, densely haired on the 

 head, thorax, and abdomen, and having the general form and 

 abdominal structure of Anthidium, but sufficiently distinguished 

 from it by the characters noted above. The first recurrent nervure 

 is almost interstitial, the second received distinctly beyond the 

 second transverse cubital. The abdomen wants entirely the yellow 

 markings found on most species of Anthidium. The first and third 

 joints of the maxillary palpi are about equal in length; the middle 

 one is as long as both united and thicker thau them ; the labial palpi 

 are as in Anthidium, the trophi being long as in that genus. The 

 mandibles, behind the apical tooth, are straight. 



Plesianthidium fulvopilosum, sp. nov. 



Black, the clypeus yellow; the upper part of the head and 

 thorax thickly covered with long bright fulvous, their lower parts 

 with long white hair ; the upper part of the abdomen with 

 fulvous, the ventral surface with paler pubescence ; wings
