elongate, longer than the abdomen, and also wider; the meta- 
thorax oblong and covered with a dense black pubescence; the 
abdomen covered with a sericeous reflexion, 
The female closely resembles the male, and is similarly 
coloured; the antenne are simple, dusky above, ferruginous 
beneath, two or three of the apical joints being entirely so; the 
abdomen is very smooth and shining and as long as the head and 
thorax. 
Length ,9, of an inch, 
This species was taken by Dr. Kannemeyer, at Burgerdorp, a 
Dutch settlement in South Africa. 
The only character that separates this insect from many species 
of Pompilide is the pectination of the antennz of the male; it is 
however, perhaps, desirable to retain Dahlbom’s genus for the 
reception of such species as have similar antenne ; the type is the 
Ctenocerus Klugii, Dahlb., subsequently described by Lucas under 
the name Clavelia pompiliformis, Ann. Ent. Soc. Fr. 1852.

Black; the face and cheeks clothed with hoary pubescence, 
the mandibles ferruginous at their apex ; the joints of the antenne 
bipectinate, the pectinations irregularly toothed ; thorax shining, 
finely punctured, thinly clothed with hoary pubescence; the 
wings hyaline and iridescent; the claw-joint of the tarsi ferru- 
ginous, the calcaria pale testaceous; abdomen shining, mar- 
gins of the segments depressed ; finely punctured, and with a 
thinly scattered hoary pubescence. 
Male.—Length 4 lines. 
Taken near Sydney, Australia. 
This remarkable bee is still unique in the British Museum. 
The beautiful ramose antennz of the male present perhaps the 
most remarkable example of those organs known in the entire 
tribe of the Aculeata ; such an extraordinary departure from the 
normal form of antenna could scarcely have been looked for in 
the Apide, and if met with at all, might with much greater proba- 
bility have been expected to occur amongst the Z'enthredinide.
