Abstract

Described from the following material: one male and one female reared from the nest of Bicyrles quadrifasciata Say, taken at Adaton, Mississippi, August, 1922, and three females collected about a Bembicid colony at the same locality (H. W. Allen); one male, Agricultural and Mechanical College, Mississippi, August 7, 1922 (H. W. Allen). In the U.S. National Museum, aside from the type and allotype: one female taken as it emerged from the nest of Bembex spinolae, June 6, 1914, Washington, D.C . (J.B. Parker); one female labeled "Parker Note No. 44," concerning which Professor Parker has furnished the information that, "this fly was captured as it emerged from the nest of Bicyrtes ventralis. Say, into which it had dashed in pursuit of the wasp as she entered with a Hemipterous insect." A male from Glen Echo, Maryland, August 30, 1923, in the collection of J. R. Malloch. A male and a female taken in coitu, at West Springfield, Massachusetts, July 25, 1915 (H.E. Smith), loaned by the Museum of Comparative Zoology, agree with the type in the number and position of the orbital bristles and in the degree of thickening on the arista, but the front is narrower as in rubriventris, and there are no median marginal bristles on the second abdominal segment in either; also two specimens from the same locality in the collection of the Boston Society of Natural History.
