Argyramoeba argentiapicalis, mihi, sp. nov. 
(Pip xxxval, dies 16): 
9. Bombay Presidency. Long. 5—7 mm. 
Head.—Frons at level of antennae rather less than one-third 
width of head, black with black hairs, with which are intermixed 
on the lower part some dirty greyish scales. Antennae black, 
normal. Face black with thick black bristly pubescence and some 
greyish scales. Proboscis dark, mouth opening very narrowly pale. 
Back of head wholly black. 
Thorax.—Blackish or blackish grey with very short black 
pubescence and with mainly black bristly hairs on anterior margin, 
around the wings, and about the shoulders and pleurae. A little 
grey hair intermixed adjacent to the head. 
Abdomen.—Black, shortly black pubescent. A spot formed 
of silvery white scales towards the sides, on the hind borders of 
Ist and 2nd segments. A few intermediate scales suggest the 
possibility that in some specimens the whole hind border of at 
least the 2nd segment may be similarly scaled. The tip of the 
abdomen (two segments) is covered with very conspicuous, elongate, 
shining silvery white scales, which are sparser or nearly absent 
on the median line. Belly black, black pubescent; genitalia 
comparatively prominent, dull brown, consisting of a pair of 
large lamellae and other parts. Anterior corners of abdomen 
with copious greyish white hair; sides with black hair. 
Legs.—Femora black, bearing a little sheen through the 
presence of very small greyish, closely impressed scales; tibiae and 
tarsi reddish brown. ‘The usual pubescence. 
Wings.—Clear, more than the basal half dark brown; the line 
of demarcation, which is emarginate at each of the veins it crosses, 
running from the tip of the Ist longitudinal vein to the middle 
(on wing margin) of the last posterior cell; thus passing distad of 
the base of the 3rd vein and the discal cell. Anal cell closed just 
before or actually on the wing margin. The endings of the 4th 
longitudinal vein are liable to variation, as in the type there is 
an extra cell formed below the discal cell (in one wing only), 
caused by the upper prong of the lower branch of the 4th vein 
curving towards and joining the lower prong, thus closing the 4th 
posterior cell. In the dark part of the wing are small lighter 
yellowish spaces irregularly disposed. Halteres black.
