 Description.' — Female. Black ; the antennae are red- 

 dish ; the femora and tibiae are reddish, but are stained 

 darker in parts ; the tarsi are yellow. 



The front is shining and a little punctate ; two more 

 or less parallel depressions contain the unevenly distribut- 

 ed punctures, and run from the ocellar tubercle towards 

 the antennae, ending at a deeper median depression 

 situated a little before the antennae. The eyes 

 are bare. The thorax, scutellum, and abdomen 

 are evenly and densely punctate dorsally, and the 

 punctures are unevenly dense ventrally; all the punc- 

 tures are small. The pubescence is silvery around the 

 antennae and mouth, elsewhere it is golden yellow ; some 

 very inconspicuous black pubescence can be seen on the 

 front and elsewhere. The wings are hyaline and the veins 

 are reddish and dusky yellowish. The haltci-es are yellow 

 with black apices. 



The male is similar to the female, but is more slender 

 in build; the eyes are approximate, and the punctures on 

 the body appear a. little less uniformly and densely dis- 

 tributed ; the legs are pale yellow, and the femora are 

 stained with fuscous; the halteres are pale yellow. 



Variation. — A female from Dunalley has the legs simi- 

 lar to those of the male. 



Length. — Male, 4 mm. ; female, 3^-4| mm. 



Type, — The holotype 9 was taken at Hobart on the 

 26th January, 1917, the allotype $ came from the same 

 locality on the 29th December, 1917; both these specimens 

 are in the Australian Museum. Two female paratypes are 

 from Hobart on the 22nd January, 1916, and Dunalley 

 29th January, 1918, respectively. In all there are one 

 male and three females taken in and around dwellings, 

 three in the centre of Hobart and one in a farmhouse at 

 Dunalley.

 may belong to this species. The flight is similar to that 

 of species belonging to the genus Odontomyia.
