type found in the Limnobiinse ; ninth tergite with a broad 

 I^-shaped notch, the lateral lobes broadly rounded ; pleurites 

 cylindrical ; pleural appendages meeting across the genital 

 €hamber. 



Habitat. — North Queensland. 



Holotype, (J, Meringa, near (Jairns, 19 IS (J. F. 

 Illingworth). 



Paratopotype, 3*- 



Phymatopsis brevipalpis agrees well with the genotype 

 ■and only described species, P. nigriroslrift Skuse, in the 

 prominent tubercle on the vertex, the long rostium without 

 a nasus, the short antennse with the terminal segments 

 distinctly* smaller, the simple male hypopygium and the 

 details of venation, especially the small, rhomboidal cell 

 Ind Ri and the very narrow cell 2nd A. It departs from the 

 characters of the genus in the unusually short palpi, the 

 terminal segment being very small and not at ;:11 flagelli- 

 form, and in the antenn?e having but eleven segments.

One female specimen taken at light, Babinda, North

Similar to the male, the following characters, additional 

 to those given in the original desci"iption being noted : 



Flagellar segments of the antennae with the tips narrowly 

 and indistinctly pale to produce a somewhat l)icolorous 

 appearance. Mesonotal praescutum \\ith the lateral margins 

 dark brown. Femoral ctenidium distinct ; claws of female 

 simple. The pale wing-apex includes the outer end of 

 cell ^3, the outer half of i?,, and all of ilfj. Ovipositor
