scutellum coarsely rugose, median segment punctured- 

 reticulate ; (lie mesonotuin with two short longitudinal carinse 

 from ncir the middle of the anterior margin. Angles of the 

 pronotum produced into a minute spine on each side. Pleura? 

 finely punctured-rugulose and sparsely clothed with very 

 delicate white pubescence ; hind coxa; shining, indistinctly 

 transversely striated at the base. 



/Lib. Yallingup, S.W. Australia (Turner), November and 

 December 1913 ; rive males and sixteen females. 



Very nearly allied to F. rogenhoferi, Schlett., which is only 

 kimwn to me by description, but differs in the much shorter 

 terebra and in the very small development of the angles of 

 the pronotum. 



Pristaulacus fuscocostalis, sp. n. 



£. Nigra; tarsis antieis brunneis ; alis subhyaliuis, costa cellula- 



que radiali late infuscatis. 

 IiOiig. 19 mm. ; terebrse long. 19 mm. 



$ . Head behind the ocelli subopaque, smooth ; front 

 opaque, coriaceous. Cheeks fully as long as the scape 

 Second joint o\i the flagellum three times as long as the first, 

 half as long again as the scape, third joint distinctly longer 

 than the first and second combined. Head not margined 

 posteriorly ; the posterior ocelli nearer to the eyes than 

 to each other, separated from the eyes by a distance equal to 

 the length of the first, joint of the flagellum. Neck not very 

 short ; mesonotum coarsely transversely striated, the median 

 lobe strongly depressed in the middle anteriorly ; scutellum 

 transversely striated, finely punctured on the sides. Pro- 

 notum not produced at the angles ; pleurae irregularly striated, 

 finely and closely punctured below the wings. Dorsal surface 

 of the median segment transversely striated, the surface of 

 the posterior truncation irregularly reticulate, with an almost 

 smooth bell-shaped median area bounded laterally by carina 1 . 

 Abdomen clavate, a little longer than the head and thorax 

 combined, smooth and shining. Hind coxaa transversely 

 rugose-striate, more coarsely at the apex than at the base ; 

 hind metatarsus much longer than the four apical joints 

 combined. First recurrent nervure received by the first 

 cubital cell, the distance between it and the first transverse 

 cubital nervure equal to nearly two-fifths of the length of the 

 recurrent nervure. 



Hub. Cairns, North Queensland (F. P. Dodd). 



This large species is easily distinguished by the broad 

 fuscous costal band. The abdomen is more slender and has 

 a longer petiole than in most Australian species of the genus.
