182 THE CANADIAN ENTOMOLOGIST. 



This species is frequently found in the stables. It places its eggs in 

 clusters on fresh manure. In one case 285 puparia were found in one 

 mass of manure. Development occupies from 9 to 20 days, depending 

 upon the temperature. 



Pyrellid cyaiiicolor Zett. — Victoria, Oct. 4. Twenty specimens. 



*MoreUia micans Macq. — Dallas, 17, 22. Thirteen specimens. 



^Mtisca domestica L. — Dallas, Tex., June 17, 19, July 20, 31, 

 Aug. 19. Fifty specimens. 



This is one of the most common species in the stables. Fresh manure 

 attracts it in great numbers. 



Stoinoxys calcitra7is L. — Dallas, Aug. 3. One specimen. 



This species is very abundant in and about the stables, but, judging 

 by our records, does not breed commonly in cow manure. 



"^Hcemaiobia serrata Desv. — Dallas, June 22, July 26, Sept. 14, iS, 

 19, 21, 22, 28, Oct. 8, 14. Victoria, July 18, Oct. 4, Dec. 10. Fifty- 

 three specimens. 



This species is to be found in the milking-houses. It varies greatly 

 in numbers with the weather. Dry weather prevents development, and a 

 series of showers invariably brought about a sudden and conspicuous 

 increase in numbers. 



"^ Myiospila meditabunda Fabr. — Dallas, July. Twenty-two specimens. 



This species was not observed in the stables. 



Family anthomyid/e. 



Linmophora discreta Stein. — Dallas, July 30, Aug. 31, Sept. 5, 12, 23. 

 Victoria, May 3, 9, 25, Aug. 9, Sept. 10, Nov. i. Ninety-eight specimens. 



This is one of the most abundant species. It was not taken in the 

 milking-houses, but was frequently bred from manure deposited in their 

 immediate vicinity. 



Limnophora debilis Will. — Dallas, July 26, Aug. i, 24, Sept. 7, 16, 

 23, Oct. 7, 9, Nov. 4. Victoria, Aug. 9, Oct. 14, 20, Sept. 10, Nov. 4. 

 Two hundred and thirty-four specimens. 



This species and the preceding are apparently the most common flies 

 breeding in cow manure in Texas, except the undetermined species of 

 Limnosina. 



Anthomyia albicincta Fall. — Victoria, June 27. Three specimens. 



Apparently this species breeds in a great variety of substances. 



Pegomyia fiisciceps Zett. — Victoria, June 3. Fourteen specimens. 



This record seems to be substantiated by the breeding from human 

 excrement, as noted by Dr. L. O. Howard.
