natural habitats are all scavengers for whom the activities of 

 man produce especially favorable conditions. It seems best to 

 discuss the species separately. 



Notogramma stigma Fabr. — This striking fly is widely distrib- 

 uted through the warmer parts of America, it having been re- 

 ported from the West Indies (Fabricius), South America (Wiede- 

 mann) and Cuba (Loew). The species occurs in the southern 

 United States. There are specimens in the national collection 

 from Dallas, Beeville and Brownsville, Texas. Recently the 

 species has been reported from Hawaii by Severin and Hartung 

 (Journ. Econ. Ent., Vol. 5, 1912, p. 448) and it appears to have 

 been established there at least as far back as 1907; a specimen 

 form Mr. O. H. Swezey bears the label, " Honolulu, March 2, 

 1907." The species has now become established in the Philip- 

 pines as well. PhiHppine specimens, presumably from the island 

 of Luzon, have recently been received from Mr. D. B. Mackie, 

 of the Philippine Bureau of Agriculture. 



But little information on the breeding habits of this fly is 

 available. The specimen from Brownsville, Texas, according to 

 the label, was reared by Mr. D. K. McMillan from Solanum, pre- 

 sumably the fruit. A series of specimens from the Panama 

 Canal Zone was reared by Mr. A. Busck from the fruits of a 

 species of palm, Attalea. Severin and Hartung in Hawaii (1. c.) 

 have found the larvae infesting green Chinese bananas that showed 

 decay about the flower-scar. 



Chrysomyza demandata Fabr. — This common European species 

 was first reported for North America by C. W. Johnson in 1900, 

 he having found specimens in Philadelphia as early as 1897 (Ent. 

 News, Vol. II, p. 609). The species is now distributed over 

 practically the whole United States. Specimens are before me 

 from the following localities: Philadelphia, Pa. (C. W. Johnson) 

 Washington, D. C. (R. C. Shannon) ; Columbia, S. C. (F. Knab) 

 Tallulah, La.; Brewster County, Tex. (Mitchell and Cushman) 

 Mineralwells, Tex. (C. R. Jones) ; Dallas, Tex. (F. C. Bishopp) 

 Yuma, Ariz. (H. Brown) ; Lehi, Utah (W. A. Hooker) ; Lind- 

 say and Visalia, Cal. ; Cheney, Wash. (N. D. Showalter). 



In the Old World, according to Hendel, the species occurs
