yellow. Leg's with the coxae and trochanters obscure yellow ; remainder of the 

 legs yellow. Wings pale yellowisli, the wing-apex very narrowly infnscated, 

 continued basad as short, narrow seams along veins R-"^ and R''+^; veins dark 

 brown, C, Sc and R more yellowish. Venation: Sc^ and R^ far removed from 

 one another at tlie wing-margin, the distance on costa between them being about 

 equal to the basal deflection of Cu^ ; Rs straigiit, about equal to the deflection of 

 R*+'' ; tip of W ]>eyond r faint and without macrotrichiae ; r oblique, at 

 about three-fiftlis the length of R-+^ ; R^ oblique, about equal to R^+''' plus 

 M^+-; petiole of cell R^ less than one-half of the cell; basal deflection of Cu^ 

 about one-half its length before the fork of M; fusion of Cu- and first A at the 

 >ving-margin punctiform. Abdomen light brown, segments seven to nine 

 brownish-black in the male ; ovipositor pale.

AUSTROLIMNOBIA gen. nov. 



Palpi short. Antennae with probably sixteen segments, the flagellar segments 

 cylindrical, gradually decreasing in length from the basal to the apical, provided 

 with conspicuous appressed hairs and a few short verticils. Pseudosutural foveae 

 represented only by a small oval area; no apparent tuberculate pits. Legs long 

 and stout; no tibial spurs; tarsal segments one to three each with a single small 

 apical spur ; claws relativel,y small, simple ; enipodium present. Wings with i~5c 

 long, Sc^ not close to R^ at wing-margin ; Sc- some distance from the tip of Sc^ ; 

 Rs originating far basad, at one-fourth the length' of the wing, the fork of Rs 

 at midlength of the wing; Rs in alignment Avith R*+^; R2+^ in alignment with 

 R- ; r some distance from the tip of R^ ; cell first M^ very long ; forks of the 

 longitudinal veins deep ; cell M^ lacking. 



The type species of this genus is one of the largest and most striking 

 Eriopterine crane-flies tha.t has yet been discovered, rivalling in size species of 

 the genera Gnophomyia, Lecteria. and CIyclo7iodozi(s. No close relative can be 

 pointed out by the writer.

 of which encloses a yellow stigmal area; wing-apex broadly dark brown; three 

 pale brown blotches along the posterior margin of the wing. 



Sexl Wing, 19-5 mm.; fore leg, femur, 12-4 ram.; middle leg, femur, 13-5
