DIE BIENENFAUNA VON NEU-GUINEA.

The New Britain bee is closely allied to the last mentioned spe¬ 
cies, from which it differs in not having the whole of the upper part 
of the thorax covered with yellowish hair. The species may be a form 
of X. provida Smith, from Mysol aud Waigiou; but I cannot make out 
this with any degree of certainty, either from the original description 
(Journ. Linn. Soc. vii. p. 48) or from that given in his Monograph of 
Xylocopa in Trans. Ent. Soc. 1874, p. 274. 
j . Black; the hairs black, except on the thorax behind the tegulæ, 
where they are orange-yellow. The basal three joints of the antennæ 
are bare, smooth, and shining; the rest are opaque and thickly covered 
with a pale microscopic down; the 3rd joint is narrow and longer than 
the 4th and 5th united. The hair on the head (including the face) is 
long, dense, and deep black. The clypeus is closely and deeply punc¬ 
tured ; its top, centre, and a curved line on the sides are smooth and 
shining; its apex is distinctly raised and separated. The mandibular 
teeth are bluntly rounded; the upper is rounded and not much shor¬ 
ter than the lower. The wings are fuscous black, with a dull greenish 
iridescence ; the 2nd transverse cubital nervure has on the upper two- 
thirds a straight, oblique slope; the lower third is not, or only very 
slightly, oblique; the upper and lower halves of the 2nd recurrent ner¬ 
vures are oblique, straight, and form an angle at their junction and 
are not roundly curved as in X. aestuans. L. 24 mm.»

Antennæ black; the last joint straight and oblique on the lower 
side. Head black, closely and distinctly punctured; the apex of the cly¬ 
peus and the part between the antennæ thickly covered with long white 
hair ; the front bears also longish hair and the vertex is covered with 
short pale hair ; base of the mandibles is closely and distinctly punctu¬ 
red ; apical tooth is long, becomes gradually narrower towards the apex 
which is rounded, it is widely grooved in the middle. Thorax closely 
and uniformly punctured ; pubescence is short, stiff, dense and black 
above ; on the side it is longer and not so deeply black in colour. Legs 
black, the apical 3 joints of the fore tarsi brownish and they are cove¬ 
red with pale hair; the hair on the middle pair is more rufous in tint.
