Mr. J. R. Malloch on Ezotic Muscaride. 161 
and in his synoptic table under the heading ‘ Besonder- 
heiten,” though a few more examples are referred to in the 
ensuing description of the species. Altogether not more 
than half a dozen species are characterized by the possession 
of these organs. Cognetti, on the other hand, not only 
mentions their existence in a larger number of species, but 
also particularly states their absence in 7’, ophioides. I am 
disposed to think that these papille are very general, but are 
not always so clearas in Th. cognetti, and are better visible in 
rather softened examples than in well-preserved and opaque 
specimens such as those of Zh. gulielmi. The subject 
obviously requires further investigation. 
XV.—Ewotic Muscaride (Diptera).—T. 
By J. R. Mattocn, Urbana, Ill., U.S.A. 
Tue material upon which this and succeeding papers of the 
series are based belongs to the British Museum and the 
Imperial Bureau of Entomology and was submitted to me 
for identification by Dr. Guy A. K. Marshall and Mr. F. W. 
Edwards. 
I have decided that the family Anthomyiide of authors is 
not separable from Muscaridz and unite them herein. ‘This 
course has been adopted by Stein in some of his recent 
papers also, but he has retained for the group the name 
Anthomyiide, which is not correct in my opinion, as 
Musca and Muscaridz have priority over Anthomyia and 
Anthomyiide. 
Many of the species dealt with in this and other papers of 
the series were originally placed in genera, the genotypes of 
which are of Palearctic origin, and in most cases the exotic 
forms are not in my opinion congeneric with the Palearctic. 
Consequently I have transferred those species to new genera, 
citing the genotype and giving a short diagnosis of the genus 
in all cases where this has been done. 
I intend publishing as part of the series, keys to the 
genera of the different faunal areas dealt with as soon as 
the material is all identified.
