A New Signiphora from Queensland, Australia 



(Hym.). 



By A. A. GIRAULT, Nelson (Cairns), North Queensland, 



Australia. 



The following new species was captured too late to be in- 

 cluded in my monograph of the subfamily Signiphorinae, now 

 in course of publication in the Proceedings of the United 

 States National Museum. I also record another species new 

 to the fauna of the continent. The new species is the twenty- 

 eighth of the genus. 



Genus SIGNIPHORA Ashmead. 

 1. Signiphora reticulata new species. 



Normal position. 



Female. Length 0.80 mm. Moderate in size for the genus. 



Black, the head and thorax dark metallic green, the wings perfectly 

 hyaline, with no proximal fumation. Venation, legs and antennae 

 brownish black. Proximal three tarsal joints and much of the ceph- 

 alic tibia, yellow. Mesonotum and vertex, finely, transversely lined. 

 Abdomen, the rectangular (wider than long) scutellum, the trans- 

 verse mesopostscutellum and the triangular propodeum all similarly, 

 distinctly polygonally reticulated. Discal bristle absent. Stigmal vein 

 conical. Marginal fringes of the fore wing very short, those of the 

 posterior wings slightly longer, the latter wings very broad, where 

 widest full three-fourths the width of the fore wings. Antennal club 

 conic-ovate and moderate in length. 



Male. Not known. 



Described from a single female specimen mounted in bal- 

 sam and captured with the sweeping net in a forest near Ayr, 

 O., November 6, 1912. (From 2-3-inch objective, i-inch optic, 

 Bausch and Lomb.). 



Habitat: Australia Ayr, Queensland. 



Type: No. Hy. 1281, Queensland Museum, Brisbane, the 

 foregoing specimen in xylol-balsam. 



Belongs to the nigra group and to that section of it where the 

 marginal fringes of the fore wing are very short. Closely allied 

 with the Australian species corinna Girault (description still in 

 MS. in the monograph mentioned) from which it differs in 

 bearing hyaline wings, narrower fore wings and in being much
