218 MEMOIRS OF THE QUEENSLAND MUSEUM. 



GYROLASELLA BIFASCIATIFRONS new species. 

 Female: — Length, 1.40 mm. Wings hyaline. 



Golden yellow, marked with metallic green as follows: A bow-shaped 

 line across the occiput cephalad of middle ; an angular dot in front of each lateral 

 ocellus ; two slender lines across the face, the dorsal somewhat below the middle 

 of the eyes, the ventral three the antennal insertions, at the ventral apex of the 

 eyes ; tip of scape and base of pedicel dorsad ; a uniform line down meson of 

 scutum; a round dot on scutum on each side centrally of this line a little 

 cephalad of middle ; a uniform, more thickened line down meson of scutellum 

 except for a short distance on each end; a small triangular spot base of post- 

 scutellum at meson ; a dot about centre of the curved, oblique cephalic margin 

 of the axillae and another one nearly in a line with it longitudinally near caudal 

 margin ; a line across the latero-clorsal margin of the transverse pronotum ; 

 parapsidal furrows very narrowly ; cephalic margin of propodeum very narrowly 

 to spiracle, a subquadrate area suspended from this at about the middle of each 

 side ; a V-shaped marking centre of base of abdomen ; four slit-like transverse 

 marginal spots on abdomen : five cross-stripes, the first faint, bow-shaped, joined 

 to the V at base and immediately followed by a pair of transverse spots (one on 

 each side of meson) which are about equal to and opposite to the first marginal 

 spot; stripes 2-5 composite, a bow-shaped more obscure ground stripe with a 

 distinct, straight stripe on it, 5 shorter (latero-laterad), none reaching the 

 marginal spots ; last marginal spot about opposite stripe -1 ; a dot on each margin 

 of abdomen near apex and a minute longitudinal one at meson cephalad of but 

 between the marginal dots; also apex of ovipositor valves, apex of tegute and 

 caudal suture of axilla. Legs immaculate. Scutellum with four isolated bristles. 

 Venation yellow, the stigmal vein dusky or infuscated, longer than the post- 

 marginal. A metallic green spot cephalad of the end of the metallic green 

 cephalic margin of propodeum; this spot is acutely prolonged mesad; also the 

 suture of the mesopleurum is metallic green and a transverse spot on cephalic 

 margin of scutum near lateral end. Mandibles 5-dentate, the two outer teeth 

 larger. 



Described from one female caught in "fir-bushes," forest lowlands, bank 

 of Hawkesbury River, Brooklj^n, N.S.W., November 9, 191-i. 



Type : No. Hy 3560, Queensland Museum, the specimen on a slide. 



SCOTOLINX new genus. 



Female: — Belongs to the Ophelinini. Runs to OpheUminiis Girault but 

 the funicle is only 2-,jointed, the antennie 9-jointed. Abdomen sessile, flattened, 

 ovate. Pronotum well developed but not especially large. Parapsidal furrows 

 complete. Scutellum simple, with four bristles. Axillie advanced half cephalad 

 of the scutellum. Propodeum only about half the length of the rather large 

 postscutellum at the meson, much longer laterad, its caudal margin straight. 

 Mandibles bidentate, the second or ventral tooth truncate but its dorso-distal 

 apex subacute. ^Marginal vein shorter than the submarginal, two and two thirds 

 times longer than the stigmal, the postmarginal shorter than the well-developed 

 stigmal. Club without a terminal nipple. Hind tibial spurs distinct, a little 

 unequal. 



1. SCOTOLINX GALLICOLA new species. Genotype. 



Length, 1.45 mm. Pale honey yellow, the wings hyaline, the funicle, club 

 and five cross-stripes on abdomen, dusky black. First cross-stripe out from base
