antennal joints combined. A single row of shoi'fc black bristles behind 

 eyes. Occiput covered witli sliort golden hairs, developed into a beard- 

 like growth below, but shortening again on the anterior part of the 

 geu88. A row of twelve frontal biistles on either side of frontal stripe. 

 Verticals well developed ; lateral verticals small. Vibrissee inserted well 

 above oral margin. About nine facial bristles present ; an irregular I'ow 

 of nine extending from these along the borders of the raesofacial plate, 

 just internal to the ptilinal suture, about half-way towards the insertion 

 of the antennte. Proboscis brown, in places nearly black ; palps dark 

 brown. 



Tliora.r slightly narrower than head, golden with three longitudinal 

 black stripes, the lateral paii* curved faintly outwards and considerably 

 wider than usual. The middle line extends very definitely on toscutellum; 

 the laterals do not, but a short black mark on the posterior outer margin 

 of the scutum is continued on to the scutellum. Microchsetfe on thorax, 

 especially on scutellum very strongly developed. 



Of the anterior acrostichals only the last two pairs are differentiated, 

 and are considerably larger than usual. Of the posterior set, only the 

 prescutellar are developed ; they extend over two-thirds the way to the 

 posterior border of the scutellum. Row oF dorsocenti"als very well 

 developed. Three humerals and three intra-alars present. Apical scutellars 

 present. Anterior spiracle black with dark chocolate hairs. Sides of 

 thorax grey, tinged with gold, very hairy. Ventral side grey. 



Legs grey and black. First femur faintl}'^ tinged with gold. The 

 longitudinal rows of bi'istles very complete ; under side scantily clothed 

 with long hairs; tibia slightly shorter than femur, and not hairy. Second 

 femur slightly hairy on its proximal venti'al half; "comb" very well 

 differentiated ; tibia a little shorter than femur and not hairy. Third 

 femur and tibia hairy. 



Ahdmtteii pi'ovided dorsally with short reclinate bristles ; hairy 

 ventrally. Hypopygium black and very hairy. Forceps shiny black, the 

 termination slightly hooked and sharply pointed ; hairy almost to tips, 

 the growth becoming very dense on the upper two-thirds. The penis is a 

 rather complex structure; the distal joint is divided into an anterior and 

 posterior portion, each provided with curious processes as tignred. The 

 nature of the claspers could not be observed in the specimen available. 



Female. 



This differs fi'om the male in the following characters : — It is rather 

 smallei', measuring about 10 mm. in length. Frons a little wider than 

 eyes. Frontal stripe about as broad as parafrontals. Frontal bristles 

 arranged in an inner row of nine beside frontal stripe, and three above, 

 just internal to eyes. Lateral verticals very prominent. Apical scutellars 

 absent. Second femur not markedly hair}-, "comb " absent. Third femur 

 and tibia entirely devoid of haii-. 



Described from a male and a female collected by Mr. G. H. Hardy 

 at Launceston, Tasmania, in October, 1916.
