 two females with a female of {Stephanodes) Poly?iema psecas 

 on a stable window at Mattoon, Illinois, July 16, 1910; and 

 by sweeping grass in an orchard at Du Bois, Illinois, June 

 23. 1910, a single male. The species therefore is distributed 

 as follows in the United States : New York (Albany, Ge- 

 neva); Missouri (various localities); Illinois (Urbana, Algon- 

 quin, Butler, Mattoon and Du Bois); District of Columbia; 

 Virginia (Roslyn); Indiana; Texas (College Station); Kan- 

 sas (Riley County); and Colorado. 



Variation occurs in striaticoDic but not to any extent ; the 

 third funicle joint may be relatively shorter in some speci- 

 mens in relation to the second, somewhat as is normal in 

 enchenopce for instance ; the proximal tarsal joints of the 

 caudal legs may be shorter in some specimens ; in the males, 

 the scape may vary to yellowish and even the first funicle 

 joint, occasionally, may vary to the same color ; also in an 

 occasional specimen, the antennal joints will appear to be 

 shorter than typical. In both sexes the dusky black of the 

 legs will vary in intensity and also in individuals of both 

 sexes, at certain aspects, the peculiar sculpture of the 

 " genus " Stiphanodes Enock is observable on the scape but
