chestnut-brown or blackish with the usual stripes and grey 
tomentum; pubescence black, rather thick, with a bunch 
of white hairs above the base of wings; bristles black. 
Scutellum with white hairs on its anterior border and black 
aud yellow bristles beyond, the latter predominating—the 
black bristles always on dorsum, not on border. Abdomen 
with the usual black spots ; pubescence chiefly yellow, some 
black on the posterior segments ; underside with whitish 
hairs, the border of the last segment does not appear to be 
produced, but is bordered by the very thick coarse black 
hairs forming a thick tuft on each side, coalescing in the 
middle. Genitalia extremely short and small, black and 
shining, with black pubescence; the upper forceps stout, 
the white hairs above are thick and extend to the apices of 
forceps. Legs dull brick-red, the femora with black stripes 
above, the legs with thick white pubescence and many 
white bristles on the tibiee. Wings clear, with reddish- 
yellow veins. 
Female identical. Ovipositor with some whitish pubes- 
cence, nearly as long as the last two segments together.

russas collected by him in the island of Tali Aboe, in the Sula 
group, east .of Celebes—a locality where they had been 
reported to exist, but from which, so far as I am aware, no 
specimens had been brought to any European Museum. In 
working these out and comparing them with the Babirussas 
of Buru and Celebes a certain number of interesting points 
have turned up, which may be worth publication. 
Firstly, as regards the spelling of the names of the genus 
and type-species, these are quite correctly put by Lydekker * 
Babirussa babyrussa, none of the other variants of the two 
names being technically admissible. This being the case, it
