NEW c;ENERA and species of AUSTRALIAN 



MUSCOIDEA. 



BY CHARLES H. T. TOWNSEND, 

 BUREAU OF ENTOMOLOGY, WASHINGTON, D. C. 



The Muscoidea of all the principal regions of the earth have 

 been catalogued, after a fashion, more or less completely, except 

 those of Australia and Tasmania, which still stand without any 

 published list whatever. The writer has recently prepared a com- 

 plete synonymical catalogue of the Australian muscoid fauna, 

 including that of Tasmania, in the course of which he has found 

 it advisable to erect genera for certain described forms whose 

 characters are sufihciently clearly recorded to allow of such action, 

 credit being due to Brauer and Austen for elucidating the several 

 types of Macquart and Walker concerned. These genera are 

 presented in the present paper, together with descriptions of a 

 few additional genera for new forms represented in the U. S. Na- 

 tional Museum collection. 



Paracalliphora, new genus. 



Genotype, Calliphora oceanicB R. D., 1830, Myod., 438, Port 

 Jacl^son and Timor (Brazil in error). 



Differs from Musca (Calliphora) as follows: Epistoma more 

 produced, not so constricted by the vibrissal angles. Ocellar bristles 

 wanting in male, weak or vestigial in female. Cheeks and front 

 both averaging narrower. Scutellum with only two strong marginal 

 pairs of macrochseta? besides the apical pair. Abdomen scarcely 

 broader than the thorax, much less thickly hairy. (Nine specimens: 

 4, Sydney, H. Gurney; 2, Reedy Creek, N.S.W., maggots from 

 sheep; 3, Australia, Koebele, No. 483). 



Calliphora tibialis (1st) Mcq., 1846, Dipt. Exot. Suppl. I, 

 195, Tasmania and Australia, belongs to this genus. Brauer»(Sitz. 

 Ak. Wiss. CVIII, 524) says: "Gehort mit M. stygia F. zu Pollenia 

 villosa R. D." This would seem to be wrong, as specimens men- 

 tioned below in U. S. N. M. coll. agree fairly with Macquart's 

 description and are congeneric with Oceanian. They bear a strong 

 superficial resemblance to villosa, but lack the fulvous hair of 

 abdomen. (Three spms.: Croydon, N. S. W., W. W. Froggatt).
