Texas: Male, Colorado County, June 6, 1022 (Grace Olive Wiley) ; male, Dallas, 

 October 9, 1905 (F. C. Bishopp) ; 2 females, Mineola, July 19, 190G (Bishopp 

 and Jones) ; 3 males, Wharton, June 24, 1917; male, Wharton, September 

 17 (A. McLaughlin) ; male, Richmond, May 29, 1918 (J. C. Bradley) ; 4 

 males. 



Washington: Female. Wawawai, August 30, 1908 (W. M. Mann). 



Wyoming: 2 males, Worland, August 1, 1911 (L. Bruner). 



This species is parasitic on both Bemhm pndnosa Fox and Micro- 

 heTThbex monodo7ita Say. The host relationships and the variation in 

 size have been discussed by the autlior (1924). 



The pubescence of the females varies in color from bright fer- 

 ruginous to pale yellow. In some male specimens the vertex, prono- 

 tum, mesonotum, scutellum, and postscutellum are clothed with erect, 

 ferruginous to yellow pubescence, but in others the vertex and prono- 

 tum are clothed with black pubescence while the ferruginous to yel- 

 low pubescence is confined to the mesonotum, scutellum, and post- 

 scutellum. The second abdominal sternite of the males appears to 

 lack the median pit filled with hairs which is present in related spe- 

 cies. This character is practically obsolete in hioculata. although 

 there is a faint indication of this pit in nearly all specimens. It is 

 so faint, however, that it is only noticed in careful observations and 

 is a mere rudimentary impression, not to be described as a pit. Bio- 

 culata is very closely related to lepeletieni. The genitalia of the 

 males of both are identical and since those of lepeletierii are figured 

 it has not been thought necessary to figure those of hioculata. The 

 females placed here have been compared with the type of aegiiia 

 and found to be the same.
