886 DIPTERA OF AUSTRALIA, 



articulis 3tio ad 31mum ramulum longissimum gracilem pilosura 

 e basi emittentibus (fig. 5) ; oculi maris maximi interne lunati, 

 subtus fere conniventes. Palpi perbreves 3-articulati, articiilo • 

 Imo minuto, 2do majore subovato, 3tio paullo majori, spatub'- 

 formi. Thorax ovato-rotundatus. Abdomen maris longum 

 cylindricum, unguibus duobus terminatum" (Westwood). 



" Rostrum not longer than the head ; palpi rather long (West- 

 wood says : palpi perbreves 1) ; as far as I can see, the last joint 

 is not longer than the others. Thorax small compared to the 

 length of the abdomen ; the latter narrow, of equal breadth, very 

 slightly broader at the forceps ; the forceps seem to have the same 

 structure as in Gynoplistia. . Legs comparatively stout ; tibiae 

 with spurs ; empodia present. Wings : venation like that of 

 Gynoplistia^ with the exception in the course of the auxiliary 

 vein (which ends in the first vein) ; first sub-marginal cell rather 

 long, its proximal end but little distant from proximal end of the 

 second sub-marginal ; the second posterior with a long petiole ; 

 the great cross-vein near the middle of the discal cell " (Osten- 

 Sacken). 



Ohs. — This form is quite unknown to me. Baron Osten-Sacken 

 has seen the two original specimens from which the above was 

 drawn, enumerates additional characters of the genus, and more- 

 over describes another species (Studies II. p. 213) from New 

 Zealand. In a (J specimen of the latter in the possession of 

 Baron Osten-Sacken the antennae are 39-jointed, whilst in 

 another of the same sex in the Berlin Museum the antennae are 

 36-jointed. Towards the tip of the antennae the branches and 

 joints both seem to be liable to modifications similar to those 

 observed amongst the closely allied Gynojylistice.
