DIPTERA FROM THE SOUTH-WESTERN UNITED 



STATES 



Paper IV. Anthomyiidae^ 



BY J. R. MALLOCH 

 Urhana, Illinois 



For several yeare I have been making an exhaustive study of 

 Anthomyiidae from North and South America and Europe, with a 

 view to obtaining data upon which to base a rehable family, sub- 

 family, and generic classification of the calypterate Muscidae, and 

 it was with this end in view that I undertook the work upon the 

 present collection. The work was undertaken with the permis- 

 sion of Dr. S. A. Forbes, chief of the Illinois State Natural History 

 Survey, and the material was studied in conjunction with that in 

 the Survey collection, a few species from the latter collection being 

 added where it was considered advisable to do so, in order to 

 make the paper more complete and to supply comparative data 

 or records. 



[This is the fourth of the series of papers based on the material 

 collected in Texas and New Mexico, in 1902, by H. L. Viereck and 

 J. A. G. Rehn, on an expedition under the direction of The 

 Academy of Natural Sciences of Philadelphia. 



Included in this paper is material from California and Idaho, 

 collected by E. T. Cresson, Jr., and from several other, mostly 

 western, localities secured by various collectors. In the latter 

 cases the collector's name, when known, is given within paren- 

 theses. In every case unless otherwise designated within brack- 

 ets, the material studied is from, and the types of species from 

 such material are in, the collection at The Academy of Natural 

 Sciences of Philadelphia. 



A key to the subfamilies of the Anthomyiidae will be found in 

 the Canadian Entomologist, for 1917, page 406. E. T. C, Jr.]
