AUSTHALIAN HYMENOPTEEA CHALCJDOIDEA. IV .—GIRAVLT. 259 



latlier broadly golden yellow aiul a golden yellow triangle at meson of cephalic vertex. Pedicel 

 • elongate, subequal to funicle 4 which is somewhat over half the length of 1, the latter elongate, 

 distinctly longer than the club, over thrice longer than wide; funicle and club clothed with 

 moderately long hairs. Club slightly nippled. Mandibles tridentate. Marginal vein distinctly 

 longer than the submarginal. Sculpture somewhat rougher than usual but normal for the 

 tribe, the propodeum slightly smoother, glabrous narrowly along the median line, noncarinate. 

 Pronotum (viewed from above when the head has been removed) large, three fourths the 

 length of the scutum. Abdomen sculptured like the propodeum. Scutum nearly naked; 

 pronotum with scattered bristles from obscure punctures. 



From one female caught by sweeping in forest, June ]0, 191-1. 



Bahilat: Gordonvale (Cairns), Queensland. 



Tyi>( : No. By 364 J, Queensland Museum, Brisbane, the specimen on a tag; head on a 

 slide. 



In the Diagnosis of Genera, antea, p. 249, line 6 of the whole, an asterisk should follow 

 the word lines. Page 250, under Melitiohia, the sentences as follows should be added: Frons 

 directed dorsad, head longer than wide, body flattened. The genus bears three ring-jointa. 

 Page 251, line 1 under II, omit the numeral 3. In the table, characters based on the propodeum 

 have no significance.

1. CERATONEURONELLA RUFOBASALIS new species. 



Fvmah : — Length, 2.05 mm. 



Agrees wfth the desi-ription of ■nigrivcniris Girault in all details but differs as follows: 

 The base of the abdomen is reddish yellow (a little less than proximal third all round); the 

 jietiole is white; the first funicle joint is suboqual to the jiedicel which is longer than in the 

 other species and the stained area on the fore wing is much less distinct, only an obscure stain 

 under about the middle of the marginal vein (a little distail of the middle). In the genotype 

 this spot is large and distinct, ovate and projects eonicall_r distad of the venation. Tip of 

 abdomen whitish. Hind coxa and femur with tlie elongate black spot. Abdomen finely scaly. 

 Segment 3 of abdomen shorter than 1, iutermeiliate between it and segment 4. Mandibles 

 tridentate. Median groove of scutum absent. Median groove of scutellum indicated by an 

 incision at base only. Funicle 3 shorter than 1, barely longer than wide. 



From two females labelled " No. 2fi. 10 10-13. G. F. Hill." 



Babitat : Port Darwin, Northern Territory. 



Types: No. ByS645, Queensland Mu.seuni, Brisbane, two tenuilcs on a tag. 



In this genus the stigmal vein is shorter than usual, the marginal vein slender, the 

 hind tibial spur longer and stout (liul not greatly lengthened), the club solid, the scutum 

 simple, the median groove of scutellum faint, the first lateral groove further laterad than 

 usual, as seen from above along lateral margin of scutellum and resembling the grooved 

 scutellum of the Elachertiui; the first grooves are absent. Hind legs, wing and antenna of 

 genotype re-examined. In the genotype, funicle 1 is only a little longer than the pedicel and 

 no longer than the other two funicle joints.
