486 Records of the Indian Museum. [Vor. VAL, 
Thorax.—Bluish grey with light brown reflections, but with no 
distinct marks; humeri distinct, rather large, brownish. Sides of 
thorax dark bluish grey, with whitish reflections seen from behind. 
Scutellum bluish grey, tinged with pale brown; metanotum bluish 
grey with whitish reflections. 
Abdomen.—Bluish ash-grey ; rather more than the basal half 
of each segment rich velvet black, extended hindwards in the 
centre until it nearly meets the next segment; these black bands 
extending over the sides and right across the ventral surface so 
that the belly is practically a replica of the dorsum. Tast seg- 
ment (6th) all bluish grey, bent under the belly and carrying a 
moderately long reddish brown shining process bearing a bunch’ of 
hairs near the tip. 
Legs.—Dark blackish brown, extreme base and tips of femora 
pale yellowish brown; tibiae blackish brown, with bases rather 
broadly, and tips rather narrowly yellowish brown; tarsi dark 
brown above, light brown below; femora with silvery white shim- 
mer, when seen in certain lights. Legs microscopically pubescent, 
hairy but without distinct bristles. 
Wings.—Distinctly pale brown. Second costal segment quite 
clear and transparent; third twice as long as the fourth, the stigma 
distinct, but ill-defined on inner side. The 4th longitudinal vein 
curved outwards in a bow after quitting the posterior cross-vein 
and possessing an appendix, commencing as far from the junction 
of the 4th longitudinal with the posterior cross-vein as the length 
of that cross-vein, this appendix extends more than half way to 
the wing border. Anterior cross-vein exactly over centre cf discal 
cell. Basal part of wing rather clear but extreme base pale yvellow- 
ish. Halteres brownish yellow. 
Described from a single @ in the Indian Museum collection 
from Margherita, in perfect condition, except that the head is 
missing. I would not have described as new a decapitated speci- 
men, but for the strikingly distinctive characters of this species, in 
which the furcation of the 4th longitudinal vein makes it impos- 
sible for it to be confounded with any other orienta! species except 
ambotnalis, Walk. 
N.B.—This species must be near furcatus, Egg., occurring 
in Europe but that species has all yellowish tibiae and tarsi. 
Walker’s species amboinalis would be almost unrecognizable 
from the brief description, except for the appendiculation of the 
‘* praebrachial”’ vein (4th longitudinal), a character I do not know 
of as occurring in any other eastern species but these two. 
Herr Kertesz does not mention this character in his notes on 
amboinalis (Ann. Mus. Hung., I, 470), founded on an examination 
of Walker’s type by Miss Ricardo, but I presume he would have 
called attention to the fact had Walker’s description been in error 
on the point. 
My appendiculaius is therefore distinguished by the mainly 
black legs and the slightly different (but, I should think, consis- 
tent) colouration of the abdomen. ‘The latter might equally well
