and femora black; apical half of posterior tibiae and the posterior 

 tarsi strongly infiiscated; abdomen blackish above, the broad mem- 

 branous margins along the plate of the first segment pale yellow; 

 venter of abdomen piceous, yellow at base. 



Male. — Essentially as in the female. 



Type locality. — Champaign, Illinois. 



Type.—Q^X. i^o. 23986, U.S.N.M. 



Described from four specimens collected at Champaign, Illinois, 

 and bearing Ashmead's type labels. The National Collection con- 

 tains the following additional material : two specimens from Lexing- 

 ton, Kentucky ; three specimens collected by G. R. Pilate at Opelou- 

 sas, Louisiana; ten from the C. F. Baker Collection, all taken in 

 Louisiana; one collected by R. A. Cushman at Vienna, Virginia, 

 June 4, 1911; and one taken in the District of Columbia June 2, 

 1884. I have also seen one specimen, taken by W. M. Mann, at 

 Wathena, Kansas, in the collection of Dr. C. T. Brues at Harvard 

 University; and one collected at Flatbush, New York, by J. L. 

 Zabriskie, which is in the collection of the American Museum of 

 Natural History. 



As originally proposed by Ashmead this species was named ^/t??"- 

 ma?ii, but as this is manifestly a typographical error, as the species 

 was intended to be named for Professor Garman, I have considered 

 it desirable and permissible to use the above spelling.

 Protomicroplitis mediatus Cresson, Ashmead, Trans. Lond. Ent. Soc, 1900, 

 p. 292. 



Type. — In the Academy of Sciences at Philadelphia. 



This species is readily distinguished from calliptcra^ to which it is 

 most closely allied, by the reddish-testaceous head and thorax, only 

 the metaj^leurae and propodeum being black; also by the hyaline 

 nonmaculated wings. 



Cuba, Mexico. 



In addition to the type the Philadelphia collection contains five 

 other specimens from Cuba and one from Mexico. No other mate- 

 rial of this species is known to me. 



5. MICROGASTER CALLIPTERA Say. 



Micmgaster calliptera Say, Boston Jouru. Nat. Hist., vol. 1, 1836, p. 264. 

 Microgaster macuUpennis Cresson, Trans. Amer. Ent. Soc, vol. 4, 1872, 

 p. 183. 



Type. — The type of calliptera has been lost, but the species is 

 sufficiently well characterized to make its identity certain. The type 

 of macuUpennis is in the Philadelphia Academy of Sciences.
