lowish. Coxae and femora yellowish, the remainder of the legs fuscous 

 yellowish. Genitalia ; basal clasp segment with a long, thickly setose, 

 narrowly triangular lobe at the internal basal angle; dorsal plate short, 

 narrowly and slightly incised, the lobes produced laterally, roundly oblique 

 and thickly setose ; ventral plate long, broadly rounded ; style long, expanded 

 distally, broadly emarginate. Type Cecid 1395- 



This interesting male was taken at Hazelton, Pa., June 12, 1910. 

 by Dr. W. G. Dietz. This species is easily separated from previously 

 characterized males by the extremely short basal portion of the stem 

 of the fifth antennal segment 



FOUNDATION OF SOME NEW GENERA AND 



SPECIES OF MUSCOID FLIES MAINLY ON 



REPRODUCTIVE AND EARLY-STAGE 



CHARACTERS. 



By Charles H. T. Towxsexd, 

 PiCRA, Peru. 



The adult specimens which serve as partial t\-pes of the following 

 forms I have been unable to secure for description of their external 

 characters. They were left by me in 1909 partly in the L^. S. X. M. 

 collection, and partly in the collection at the Gipsy Moth Parasite 

 Laboratory, and all were properly labeled with TD numbers. It has 

 been impossible as yet to locate them or have them sent to Peru, and 

 therefore their full description must be deferred until some future 

 time. Meanwhile the names are needed for use in the paper on the 

 reproductive systems, eggs and first-stage maggots, to be published 

 with figures under the title of " Contribution to a Thorough Knowl- 

 edge of the Muscoid Flies." Therefore I propose here formally to 

 found these several genera and species on descriptions as complete as 

 it is possible for me to make them at this time, necessarily drawn 

 mainly from the reproductive, egg and first-stage maggot structures. 

 I believe that the forms can be unmistakably determined in each case 

 from the characters and data given.
