HARDY. 17 



White suggests that the species should be plaeed in a genus oilier than Eristalis, 

 but does not give his reasons for the change. 



Hab.— Queensland, New Smith Wales. Victoria and South Australia. Walker 

 records it from Western Australia and Tasmania. 



Sub-family MILESIINAE. 



Genus Fitments Meigen. 



Note. — The species belonging to this genus are about the size of a small 

 species of the genus Syrplttts, which they somewhat resemble, and are often slightly 

 metallic. 



Two specimens are represented from Tasmania, and can be distinguished by 

 the relative size of the hind metatarsis in the male. 



Judging from the descriptions only Eumerus fulvieornis Macquart, E. latipes 

 Macquart, and probably Mere/Ion muscaeformis Walker, belong to this genus. 

 E. marginatus Grimshaw, described from Honolulu, is stated to be a possible im- 

 portation to the Hawaiian Islands from Australia. 



Genus Xylota Macquart. 



Xylota plcnralis Kertesz was described from New South Wales, but the 

 species has not been recognised in the collections examined. The other species 

 belonging to this genus has been recognised. 



Xylota flavitarsis Macquart. 



Xijlota flavitarsis Macquart, Dipt. Exot., suppl. 1, 1840, p. 134; and suppl. 4, 

 1850. p. 146. 

 Hab. — Tasmania, a series of both sexes. Victoria, Portland, one female 

 collected by H. W. Davey in the collection of Dr. Ferguson. 



Genus Criorrhina Meigen. 



Under the name Criorrhina niali ventris, Macquart has described a species that 

 probably does not belong to this genus. 



Criorrhina spadix sp. nov. 

 PI. 1, figs 5, 6, and 7. 



Description. — This species is of a beautiful brown, almost red, colour, and 

 the face, tibiae, and tarsi are yellow; the wings are hyaline with the anterior 

 border suffused brown. 



Male. The head is short, broader than high, about as broad as the thorax 

 and concave behind. The eyes are brown and approximate at a point, not quite 

 touching. The ocellar triangle is brown and about twice as long as the maximum 

 width, and is covered with a vestiture of long brownish yellow hairs ; the antennae, 

 inserted about the middle of the head are brown and contain conspicuous hairs. 

 The epistoma is hollow below the antennae, and contains a prominent central knob; 

 the whole face from the antennal triangle to the cheeks is strongly protuberant, 

 brown in colour, but is covered with a tomentum which reflects a golden yellow; 

 so that, where in one position the face is almost entirely brown, in another it 

 appears to be almost completely golden yellow. The cheeks are somewhat small 

 and slightly prominent. The proboscis is black with a slight trace of brown. 



The thorax is brown and about as long as broad. A pair of thick median 

 stripes reach two-thirds the length of the thorax; and on each side there is a fur-
