annulations, and a long, subtermiiial arista: scutelluni rounded 

 behind, without any sign of spines; abdomen very short, broader 

 than long, and ovate. 



This genus is widely distributed through North America, 

 Europe, Asia, and New Guinea. No .species has, so far, been 

 described from Australia, but there is a specimen belonging to 

 this genus in the collection of the Melbourne Museum.

18. L O N C H E G A S T E K White. 



This genus resembles Pachyyaster, but is distinguished by the 

 form of the scutellum, which rises from the thorax at an angle 

 of about 45°, and is produced backwards centrally, in a thin, 

 spine-like prolongation, this spine being about the same length 

 as the rest of the scutellum. 



Only one species is known. 



LONCHEUASTER ARMATA White. 



Thorax and scutellum dull black; abdomen blue-black; lees 

 pale yellow; wings hyaline, with anterior veins light brown, 

 posterior veins very faint. Length, ^<^, 3 mm. 



Hab. — Tasmania. 



Of this species, four specimens are known, all of which occurred 

 on the Avindows of my house at Mangalore, Tasmania, during the 

 summer of 1911-12. One of these specimens is now in the col- 

 lection of the Melbourne Museum. 



Species of doubtful position. 



The three following species, Beris quinquecella, Beris nitidi- 

 thorax, and Berts Jusciventris, all described by Macquart from 

 Tasmania, are unknown to me; they may belong either to the 

 Beriiice or to the Antissittcf.. 



Addendum. 



Mr. F. P. Spry has been good enough to send me two speci- 

 mens of the undescribed species of Acanthasargus referred to 

 previously (antea, p. 96), so that I am now able to describe it.
