THE NEW YORK SPECIES OF ANTUOMYIIDJE. 171 



The New York Species of the Family. 



Five species of the interesting genus of Ilomalomyia Bouch^, to 

 which reference has been made (four included in the Meade list) occur 

 in the State of New York. The first two mentioned are the more 

 common. The fii'st, from its being so frequently found in houses, has 

 been called the "lesser house-fly," Musca domestica minor Do Geer; 

 the second has received its common name of the "privy-fly" from its 

 larva occurring in human excrement, particularly in the contents of 

 old vaults. The larvjB of this genus are not rounded forms as in An- 

 thomyia, but have flattened bodies, as indicated by the generic name, 

 and also in their popular name of " flat-flies." An excellent paper 

 upon these forms may be found in the American Entomologist, vol. ii, 

 pp. 137-141, from the pen of Mr. Walsh, published after his death. 

 The species are the following (the Meade numbers are prefixed to those 

 seen by him) : — 



44. Homalomyia canicularis (laic's.). New York and Mass. 



45. H. scalaris (Fabr.). N. Y., Penn., Mass., Me. 



46. H. p?-ostrata (Rossi). N. Y., Mass. 

 50. H. ep. indet. N. Y., Greenland. 



— R. tetracaniha Loew. Middle States. 



01 the genu% AntJiomyia^ieig., the larvae of which are naked, not 

 having the branching lateral appendages of the preceding genus, the 

 following Kew York species are recorded : — 



57. Anthom,yia latitarsus Slaeg. and Zett. N. Y. and N. Hamp. 



59. A. sp. indet. Similar to A. pkivialis, of Europe. 



— A. brassicfe Bouche. Perhaps same as A. ruficej)s Meig. 



— ^4. ceparutn Bouche.* Same as A. antiqua Meig., auct. Scliiner. 



— A. rapliani Harris. Perhaps same as A. radicum Linn. 



— A. similis (Fitch). Similar to Hylemyia deceptiva Fitch. 



In Hylemyia Desv., of the fourteen species indicated, four are from 

 New York, viz. : — 



60. JTylcmyia sp.? N. Y., N. J., and British America: apparently abundant. 



61. //. sp.? N. Y., Conn., and N Hampshire. 



62. U. deceptiva Fitch. N. Y., Hudson's Bay, and Arctic America. 



63. II. tarsata SiK. N. Y. and 111. Perhaps A. alcathoe W.\lk. 



64. II. sp.?: also 05 and 67, sp. indetermined. Two other species are from 



Canada and New Hampshire and are probably to be found in 

 New York. 



Twenty-two species are referred to the genus Chortophila, of which 

 nine are credited to New York, and eight additional ones from locali- 

 ties so near, as Canada, Massachusetts and Connecticut, that they may 

 be presumed to occur also in New York. Many of the species are 

 small and some are known to have an extensive distribution, ranging 

 from the District of Columbia to the Arctic regions. 



*Since the publication of this paper, the species has been removed to the genus Phorbia, 

 as will be noticed hereafter. '
