marginal fringes slioiter. The third fuuicle joint in tlie Syiiluiiiosiiliyyclla is sliortest, somewhat 

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

 shorter than 2. In the Selitrichodelia, the median groove of sfutum is not deep but delicate. 

 In the Syi^tomosiihyrcUa there can be no doubt in regard to at least two club joints while no 

 trace of the tliird can lie seen; the club is divided a little proxiinad of middle. 



To further C(ini|plic:ite matters I liave a specimen of a sjiecies agreeing witli the 

 SelitrichodcUa except tl):it there are three ring-joints and two distinct club joints. This 

 specimen differs from the Syiifomo.spliyrelUi in having tlie antenna* stouter, the mandibles 

 distinctly larger and tlie wings broader, besides tlie groove un tlie scutiim. This specimen was 

 captured at Tweed Heads. Tweed Biver, X. S. "Wales. :\Iay 14. 1914, in forest (A. P. Dodd). 

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

 femora as originally stated for the Synlonioxpliyrrlla). 



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

 Selilriclwdeliti'- w'ith which it agrees in every particular that could be made out. It has a 

 short postmarginal vein. Typ»-s re-examined.
