Oue female from Cairns Disti-ict, Queensland (Dodd). 



Diatomineura abdominaUs, ? , sp. n. 



Type (female) and another from Laurietoii, New South 

 Wales, 19.10.15. 



A species nearly allied to Diatomineura brevirostris, hut 

 distinguished from it by the absence of any white or yellow 

 haired spots on abdomen and by the first posterior cell 

 being considerably narrowed at the border, only half open. 



Length 15 ram. 



Face, pa/pi, and antenna as in D. brevirostris. Forehead 

 parallel, also the same; the frontal callus when not denuded 

 appears to be small, pear-shaped. Thorax dresdeu-brown^ 

 with short black pubescence, no stripes are visible; shoulders 

 with chiefly yellowish-white hairs continued on sides of 

 thorax as far as the scutellum, but they do not quite reach 

 the apex of scutellum ; a faint M'hite spot is visible on each 

 side of thorax near the suture, on the dorsum. Abdomen 

 amber-brown, mottled with blackish markings, smooth, 

 shining, with very short black pubescence ; sides with 

 yellowish- white hairs ; apex and sides of posterior segments 

 paler in colour ; underside paler with black spots. Legs 

 reddish-yellow ; the tarsi brownish, pubescence chiefly black. 

 Wings clear, stigma yellowish, veins brown, no appendix; 

 first posterior cell narrow at border, but open.

A series of specimens from South Australia appear to be 

 this species, judging from Macquart's description, though 

 there are a few discrepancies ; his type came from the East 

 Coast of New South Wales. 



The wings have an appendix and two brown spots, which, 

 however, amount to little more than dark shading on the 

 transverse veins. Abdomen black, at base testaceous, with
