254 MEMOIRS OF THE QUEENSLAND MUSEUM. 



marginal fringes shorter. The third funiele joint in the Syntomosphyrella is shortest, somewhat 

 wider than long, 2 longest, somewhat longer than wide, nearly as long as the pedicel, 1 a little 

 shorter than 2. In the SelitrichodeUa, the median groove of scutum is not deep but delicate. 

 Tn the Syntomosphyrella there can be no doubt in regard to at least two club joints while no 

 trace of the third can be seen; the club is divided a little proximad of middle. 



To further complicate matters I have a specimen of a, species agreeing with the 

 SelitrichodeUa except that there are three ring-joints and two distinct club joints. This 

 specimen differs from the Syntomosphyrella in having the antenna? stouter, the mandibles 

 distinctly larger and the wings broader, besides the groove on the scutum. This specimen was 

 captured at Tweed Heads. Tweed River, X. S. Wales, May 14, 1914, in forest (A. P. Dodd). 

 The second ring-joint is very short. The cephalic tibia? are all white in all three (not the 

 femora as originally stated for the Syntomosphyrella). 



After some consideration, I concluded the Xew South Wales specimen to be the 

 SelitrichodeUa 12 with which it agrees in every particular that could be made out. It has a 

 short postmarginal vein. Types re-examined. 



2. SYNTOMOSPHYRELLA QUADRIMACULATA 'Girault. 

 Equals SelitrichodeUa trimaculosa Girault. Types compared. 



3. SYNTOMOSPHYRELLA ATRIVENTRIS new species. 



Female: — Length, 1 nun. Short, robust. 



Black, the wings hyaline; the pronotnm, scutum (except for a large subquadrate 

 blackish area at base extending nearly to lateral margins) and the head orange yellow; also 

 abdomen slightly around base. Scutellum, leys except hind coxa (other coxae blackish at base) 

 and hind femur (washed with blackish), antenna' and lateral margins of scutum (more broadly 

 cephalad), contrasting lemon yellow. Scutum long; propodeum very short. Mandibles 

 tridentate. Pedicel distinctly longer than any of the funiele joints, the latter subquadrate, 

 subequal. Club without a distinct terminal seta. Antenna." washed with dusky. Stigmal vein 

 long, the postmarginal distinctly but only slightly developed. Fore wings broad. 



From one female captured by sweeping jungle, along a forest streamlet, dune 14, 1913 

 (A. P. Dodd). 



Habitat: Gordonvale (Cairns). Queensland. 



Type: No. II y 2634, Queensland Museum, Brisbane, the specimen on a tag, the head on 

 a slide. 



4. SYNTOMOSPHYRELLA ACOMATA new species of Girault and A. P. Dodd. 



Female: — Length, 1.10 mm. 



Golden yellow, the winj.s hyaline, the appendages concolorous; a spot on each side of 

 face of pronotum, the cephalo-lateral angle of each axilla, meson and caudal margin at meson 

 of propodeum (jet) and I wo spots on abdomen somewhat distad of middle, one on each side 

 of meson, blackish. Middle of cephalic margin on each side of propodeum, dusky. Funiele 

 joints subequal. each somewhat wider than long and about half the length of the pedicel. 

 Mandibles tridentate. Propodeum short at the meson. Abdomen short and stout. 



Described from two females reared from miscellaneous galls on Eucalyptus, October 6, 

 1913 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: Xo. II y 2635, Queensland Museum, Brisbane, one of the above specimens on a tag, 

 the head on a. slide. 



ls SelitrichodeUa fusdpennu must therefore be referred to Tetraslichella where the name is preoccupied. The 

 new name nubilvpennii is herewith given to it.
