Mississippi: 2 males, Ocean Springs, July 5, 1915 (F, F. Bibby).

Paratypes are deposited in the collections of the United States 

 National Museum, American Museum of Natural History, University 

 of Michigan, University of Minnesota, Cornell University, Missis- 

 sippi Agricultural and Mechanical College, and the American Ento- 

 mological Society of Philadelphia. 



This species resembles ruhricosa very much in general appearance 

 and color; it may be readily distinguished from that species by the 

 basal position of the pit on the second sternite. the emarginate an- 

 terior margin of the pronotum and the lateral depressions of the 

 occiput. 



A gynandromorph of this species was collected at Spring Creek, 

 Ga., May 18-21, 1916, by Dr. J. C. Bradley (see p. 28). The first 

 four segments of the abdomen which present female characters are 

 very similar to those of cypris (Blake) and strengthens my belief 

 that this will prove to be the male of that species.
