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 mesonotum and more robust. From 

 dadylopii 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, sub- 

 equal in length to the stigmal vein, somewhat shorter at the apex; 

 obHque 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 longitu- 

 dinal 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) .

Male. — Unknown. 



Described from a single female specimen captured from a window 

 in a granary and barn on a wheat farm at Roma, Queensland, October 

 6, 1911.

Host. — Unknown. 



Type.^—'No. Hy./772, Queensland Museum, Brisbane, one female in 

 xylol-balsam (mounted with the female type of Gonatocerus Tiuxleyi 

 Girault and specimens of SignipTiora australiensis, Abhella subfiava, 

 Ufens and Aphelinoidea all captured at the same time). 



27. SIGNIPHORA AUSTRALICA, new species, 



Normal position. 



Male. — Length, 0.54 mm.; moderately small for the genus. 



General color black, the vertex and mosonotum metallic bluish 

 green, the antennae, venation and caudal femur sooty black, the 

 tarsi and remainder of legs palfid yellowish, the distal tarsal joint 

 not much darker if at all; fore wnngs fumated tliroughout, 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;
