midlongitudinal (nearly) half being more clear. Hence, somewhat as in melancholica, the 
fum:tion is under the venation extending caudad somewhat beyond the midlongitudinal line of 
the blade. Jt is longer, however, than the clouded area of the species named. Distal tarsal 
joints only siightly darker. 
Belongs to the nigra group and to that portion of it including funeralis, australiensis, 
nigra, and dactylopii but is more closely related to the last named two. It differs from 
nigra in that the fore wings are fumated somewhat farther distad (nearly to the apex of the 
stigmal vein), the body is metallic on the head and thorax, finely, transversely lined at the 
mesonotun: and more robust. From dactylopii it differs as much as it does from nigra; 
however, the fumation of the fore wing does not form a band across the wing from the 
marginal vein but is quite different and distinct. 
The fore wings are broad, their marginal cilia very short, subequal in length to the 
stigmal vein, somewhat shorter at the apex; oblique crease slightly indicated; discal bristle 
absent; stigmal vein straight, a conical prolongation of the marginal vein. ‘Posterior wings. 
very broad, two-thirds the width of the broad fore wing, which is only twice longer than 
broad. 
Marginal fringes of posterior wings subequal in length to those of the fore wing. 
Mandibles bidentate. Proximal joint of cephalic tarsus only half the length of the same 
joint of the caudal tarsus. Antennal club stout, conic-ovate, bearing a number of short longi- 
tudinal sulei, which are arranged in three circular groups along the joint, giving the appearance 
(easually) of three joints; the club only about two and a half times longer than wide (its 
greatest width at apex of proximal third).’’

Type: No. Hy 772, Queensland Museum, Brisbane, the single female on a slide. 
6. SIGNIPHORA AUSTRALICA Girault. Male. 
The following summarizes all that is known of this species (Girault, 1913), except two 
locality records added later. 
‘* Length, 0.54 mm.; moderately small for the genus. 
General color black, the vertex and mesonotum metallic bluish green, the antenne, 
venation and caudal femur sooty black, the tarsi and remainder of legs pallid yellowish, the 
distal tarsal joint not much darker if at all; fore wings fumated throughout, the proximal 
fumation (out nearly to the end of the marginal vein) deeper, the whole divided somewhat 
distad of the middle of the wing by a moderately broad subhyaline band which is nearly 
regular in width and joining the costal wing margin at the end of the stigmal vein; the 
fore wing is also clear directly beneath the submarginal vein for nearly its whole length. 
Belongs to the nigra group and that section of it containing those species bearing 
marginal cilia at the apex of the fore wing which are subequal to or longer than a third of 
the wing’s greatest width, hence allied with maxima Girault, pulchra Girault, noacki Ashmead, 
and nigrella Girault. However, resembling australiensis Ashmead and at first mistaken for that 
species; the transverse clear band is somewhat farther distad (on the costal margin half or 
more of it extending beyond the apex of the stigmal vein), more uniform and not coming to a 
point at the stigmal vein; the longer marginal cilia of the fore wing in australica, the narrower 
fore wings, the pallid legs and other characters easily distinguish the two species. Of the four 
species with which it is allied, it resembles, perhaps, pulchra more than the others because of 
its moderately narrow fore wings, but the discal bristle is absent and the oblique hair-line-like 
crease but slightly indicated; the legs are much lighter in color. The species need hardly be 
confused with any other species of the genus, even its closest allies. 
Fore wings with the marginal cilia moderately long, those at apex only about slightly 
‘over a third of the greatest width and slightly longer than the apical marginal cilia of the
