INVESTIGATIONS ON THE MUTILLID WASPS 63 



Indiana: 3 males, Gary, July 18, 1925 (J. A. Harris, jr.). 



Maeyland: Male, Chestertown, August 4, 1902. 



Mississippi: Male, Beuna Vista, August 30, 1916 (H. L. King); male, Agri. 



College (W. F. Swan). 

 Missouri: Male, Hollister, August 12, 1912 (H. H. Knight). 

 New Jersey : Male, Lakehurst, August 15, 1912 ; male. Da Costa, July 25, 1923. 

 Pennsylvania: Male, Hummelstown, June 4, 1912 (J. N. Knull). 

 Virginia : 2 males. Falls Church, July 23, 1913 (W. Middletown) ; male, Falls 



Church, August 14, 1913 (C. T. Greene). 

 The genitalia of this species are the same as those of asopus and 

 are therefore not figured. The type of lexar has been examined and 

 the specimens placed here are identical with it. The specimens listed 

 by Melander (1903) as this species are certainly not the same as the 

 type, since mention is made that the second ventral segment does not 

 bear a carina, and the latter is very characteristic of this group. 

 Just what Melander's specimens are I am unable to say.

SPECIMENS EXAMINED 



Texas: Female, Fedor, April 13, 1897; male, Fedor, August, 1905 (G. Birkman) ; 

 male, Fedor, September 13, 1905 ; 3 males, Fedor ; female, Lee County, Sep- 

 tember 6, 1907 ; 2 males, Lee County, September 11, 1905 ; male, Lee County, 

 September 13, 1905; male, Lee County, September 20, 1905 (G. Birkman) ; 

 female, Travis County, April 3, 1903; male. College Station, August 16, 

 1914 (H. J. Reinhard) ; male, 3 females. 



I have examined the male described by Fox (1899) as having 

 rudimentary wings and believe it to be an abnormal specimen in 

 which the wings have failed to develop properly at the time of the 

 emergence of the adult insect. A second specimen with rudimen- 

 tary wings has never been found. The male specimens listed above 

 are identical with Fox's specimen in every respect except that the 

 wings are developed as in all other species of this genus. It is also 

 significant that none of the very closely related species, such as hector, 

 asopus, and hexar show any tendency toward rudimentary wings. 

 The genitalia of waco are like those of asopus and are therefore not 

 figured.
