The costal nervure (vein) is very strong, acuminate from the 
middle, and terminating towards the apex, colour brownish- 
black, base pink ; the main branch vein starts from the costal 
nervure at about one-third of its length from the base ; 
terminating beyond the middle of the hindmargin, and is dark 
coloured and prominent above ; the second branch is close to the 
first and parallel with it, but is very fine, pale coloured and 
prominent on the underside; the cubital nervure is short, also 
very fine, pale coloured and midway between the costal vein and 
the hindmargin; the membrane itself is translucent, rose 
coloured, and, in dried specimens, the superior surface resembles 
certain parts of the skin of the human finger, the depressed fine 
lines branching from the nervures. 
The legs are black, smooth, the anterior much shorter than 
the second and third pairs, which are much longer than the body, 
the middle pair being the longest. Femora more or less dilated, 
tibia linear, tarsi entire (?), claw simple, minute. 
The ova are elongate oval, ends subequal, colour orange-red, 
length 1 mm., diameter 0:5 mm., quite smooth as seen by means 
of the triple Coddington lens. 
Strong methylated alcohol, in which most of the males and a 
portion of the ova were immersed, became of a pinkish-yellow 
colour in a few days, while a white paper label became dyed of a 
rose colour in the liquid. 
Nepticula nigricansella, sp. nov. 
Metallic brownish-black. Head with long, dense, erect bristles, 
dull black; face and pronotum resplendent dark bronze in 
reflected light; antenne nearly as long as the folded wings, 
silvery towards apex ; forewings with three very narrow, nearly 
equidistant, metallic bluish-white bands ; hindwings black, tips 
brilliantly metallic ; body beneath metallic, blackish, with white 
hairs fringing the segments sparingly; legs very long, black, 
with some indistinct pale bands. Length of body—Male, 1:5 
mm.; female, 2mm. Span of wings—Male, 4 mm.; female, 6 mm. 
One male and two females, bred from leaves of Kennedya 
(Hardenbergia) nigricans. Habitat—Unley, Adelaide, S.A. 
The leaves, presented on September 4 by Mr. W. H. Grasby, 
had the underside so completely mined by the larve that the 
entire epidermis became separated from margin to margin in 
most, and partially so in others. A tiny chrysalis being detected 
fixed to the upper (still green) part on one of the veins, the leaves 
were secured in a box with a glass lid. On September 15 the 
first imago was noticed, and on the 19th two more. 
A portion of a Eucalyptus leaf from Mr. A. Zietz exhibits 
quite similar features, which give the foliage the aspect of being 
blistered, and shows that there are other species of these, the 
tiniest of Lepidoptera.
