70 MEMOIRS OF THE QUEENSLAND MUSEUM. 



iiiicllongituflin.-il (nearly) half being more clear. Hence, somewhat as in mclnncliolicn, fhe 

 I'umi.tion is unler the venation extending caudad somewhat beyond the midlongitiulinal line of 

 the blade. K is longer, however, than the rlouded area of the species named. Distal tarsal 

 joints only slightly darker. 



Belongs to the ni<ir<i gronp and to tliat ]iortion of it inclnding fiincralis. mistraliensis, 

 nU/ra, and dactrjloini bnt is more closely related to the last named two. It differs from 

 nifira in that the fore wings are fnmated somewhat farther distad (nearly to the apex of the 

 stigmal \eiu), the body is metallic on the head and thorax, finely, transversely lined at the 

 mesonotum and more robust. From (liiclyloini it ditfers as much as it does from nigra; 

 however, the fumation of the fore wing does not form a band across the wing from thn 

 marginal vein but is quite different and distinct. 



The fore wings are broad, tlieir luarginal cilia very short, subequal in length to the 

 stigmal vein, somewhat shorter at the .■ii>ex; olilique crease slightly indicated; discal bristle 

 absent: stigmal vein straight, a conical )ir(il(ingation of the marginal vein. Posterior wings 

 very broad, two-thirds the widtli 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 sulci, which are arranged in three circular groups along the joint, giving the appearance 

 (casually) 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. Ey~72, Queensland Jluseum, Brisbane, the single female on a slide. 



6. SIGNIPHORA AUSTRALICA (lirault. Male. 



The following summarizes all tluit 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 antenna^,, 

 venation and caudal femur sooty black, the tarsi and remainder of legs pallid yellowish, the 

 distal tarsal joint not nuich darker if at all; fore wings fnmated throughout, the proximal 

 fumation (out nearly to the end of the nuirginal 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 tlie sulimarginal vein for nearly its whole length. 



Belongs to the nigra gronjj and that section of it containing those species bearing 

 marginal cilia at the apex of the fore wing whiili are subequal to or longer than a third of 

 the wing's greatest width, hence allied with mii.rinui Girault, pidi'hrd tiirault, iioacki Ashmead. 

 and nigreUa Girault. However, resembling aiistralieiisis 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 ajiex 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, imlchra 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 sjiecies of the genus, even its closest allies. 



Fore wings witli the marginal cilia moderately long, those at ajiex only about slightly 

 over a third of the greatest width and slightly longer than the apical marginal cilia of the
