GONOMYIA (s. Str.) BRYANTI AleX. 



Mt. Murud, head camp, November — 1 cf . 



Mt. Penrissen, 2000 feet— 19 ; 3000 feet— 19 . 



I am not quite sure of the identification, Alexander's figures 

 not being very satisfactory. The structure of the hypopygium. 

 and especially of the aedoeagus (not figured or described by 

 Alexander) is extremely similar to that of the European 

 G. dentata de Meij. 



GoNOMYiA SYMMETRICA sp. n. (Plate 10, fig. 34, 35.) 



O*. Head blackish, rostrum brown. Antennae and palpi 

 black, flagellar segments slender. Thorax with the whole 

 mesonotum dark brownish, pleurae lighter. Abdomen brown; 

 hypopygium as figured, the aedoeagus symmetrically con- 

 structed, but otherwise of a similar type to that of the tenella 

 group. Legs blackish, except the coxae and trochanters. 

 Wings hyaline, stigma brown, veins all dark. Sc ending only 

 a short distance beyond base of Rs, Scn near its tip. Rs nearly 

 straight and moderately long ; R^ + ., scarcely arched ; R2 nearly 

 half as long as R^ and not very oblique ; Cu^a well beyond 

 base of discal cell, which is pointed at the base. Halteres pale. 



Length of body 3 mm. ; wing 3.5 mm.

Ehabdomastix flavidula sp. n. (Plate 10, fig. 37.) 



9 . Colour uniformly yellow-ochreous, except for the dark 

 brown palpi and flagellura, and the brownish legs. Flagellar 

 segments oval. Thorax bare; tuberculate pits present. 

 Abdomen almost entirely bare, with rows of fine hairs only on 

 the posterior margins of the tergites. Anterior trochanters 

 slightly elongate, a little over twice as long as broad. Wings 

 with a slightly yellowish tinge, veins mostly pale, venation as 

 figured ; Rs unusually short for a member of this genus ; R^ 

 vertical and without macrotrichia. Arcular cross- vein present. 



Length of body 5 mm. ; wing 4.8 mm. 



Mt. Penrissen, 2000 feet— 19 (type); Kalabit Country, 

 October— 1 9 • 



A rather aberrant syjecies of the genus, which seems to have 

 a good deal in common with the Australian Horistomyia.
