208 THE CANADIAN ENTOMOLOGIST 



member of this subgenus. Edwards (Ann. Mag. Nat. Hist., ser. 8, vol. 8, pp. 

 58,^ 59; 1911) has determined the Limnobia saltcns of Doleschall as falling in 

 this group of species. Almost coincidentally, De Meijere (Tijdsch, v. Ent., vol. 

 54, p. 22; 1911) determined saltcns as being a typical member of Thrypticomyia 

 Skuse. The habitus of the species of' Buglochina is very distinct from that of 

 Thrypticomyia. 



Genus Libnotes, Westwood. 

 Subgenus Pseudo^locliina, subgen. n. , 



Tarsal claws simple, the basal enlargements provided with two acute 



bristles. Wings long and narrow, cuneiform, entirely without an anal angle; 



Rs short, straight; no supernumerary crossvein in cell Sc, ; cell 1st M,, open by 



the atrophy of Mg . 



Type of the subgenus.^ — Libnotes pulchripcs Alexander. 



Dicronomyia kobusi de Meijere and D. bicinctipes Brunetti of the Oriental 

 region are likewise members of this group. In the opinion of the writer, the 

 group is closer to Libnotes than to Dieranomyia but this whole series of genera 

 and subgenera are very closely allied. 



Genus Geranomyia, Haliday. 

 Geranomyia (Geranomyia) sagittifer, sp. n. 



Rostrum and antennae black; vertex silvery grey; general coloration of 



the thorax shining orange, the mesonotal praescutum with a median arrow- 

 shaped black mark ; legs pale yellowish brown ; wings pale grey with five rather 

 small brown costal markings, vein Sc long. 



Female. — Length (excluding rostrum) 6.5 mm.; vving 6 mm.; rostrum 

 alone 2.9 mm. 



Rostrum and palpi dark brownish black. Antennae black. Head above 

 silvery grey. 



Mesonotum shiny orange, the praescutum with a single arrow-shaped 

 median black mark, 1' ' id end behind, a short distance before the suture, the 

 narrow end terminating slightly anterior to the level of the pseudosutural foveae. 

 Thoracic pleura dull ochreous. Halteres orange, the knobs a little infuscated. 

 Legs with the coxae and trochanters orange ; femora brownish yellow ; tibiae 

 and tarsi light brown. Wings pale grey, the costal and subcostal cells a little 

 more yellowish ; five comparatively small brown markings in the costal region, 

 arranged as follows : at the supernumerary crossvein in cell Sc ; at origin of Rs ; 

 at tip of Sc, ; at tip of R, and r, and at the end of the vein R2 + 3 ; cord and 

 outer end of cell 1st M2 very narrowly and indistinctly seamed \yith grey; veins 

 brown. Venation: Sc long, Sc^ extending to just beyond the end of Rs, Sc^, 

 at the tip of Sc, ; Rs long, angulated at origin, thence straight; cell 1st M, 

 pentagonally rectangular, widened distally, about as long as vein M,^2 beyond 

 it ; basal deflection of Cu just beyond the fork of M. 



Abdomen dull orange-yellow. 



Habitat. — North Queensland. 



Holotype, ?, Gordonvale, June, 1920 (A. P. Dodd). 



Paratypes, 3 J^'s, Babinda, October, 1920 (J. F. Illingsworth). 



Greranomyia (Geranomyia) nigronitida, sp. n. 



Head dark; mesonotum shiny black, the pleura yellowish; wings nearly
