THE NEARCTIC EVANIIDAE — TOWNES 535 



under the generic description, comprise about 40 percent of those I 

 have seen. 



The type of Evania tlioracica Blanchard is not in the Paris Museum, 

 and that of Ilyptiam thoracicum Shuckard is not in tlie British Mu- 

 seum. Both are probably destroyed. Since their descriptions will fit 

 several different species, the names must be assigned arbitrarily. 

 Bradley (Trans. Amer. Ent. Soc, vol. 34, pp. 154-156, 1908) has done 

 this in a reasonable manner, and his disposition of the names is fol- 

 lowed. He synonymized thoracicum Shuckard with thoracica Blan- 

 chard, redefined thoracica Blanchard, and reported on a number of 

 specimens that he identified as thoracica. His specimens and descrip- 

 tion belong to the present species.

Nearly all dates of capture fall between June 20 and July 31, indi- 

 cating a single generation a year. Records outside of these dates 

 are : May 21 and June 4 at Southern Pines, N. C. ; May at Brownsville, 

 Tex.; June 15 at Beltsville, Md.; August 2 at Falls Church, Va.; 

 August 15 at Wellesley, Mass.; August 20 at Orlando, Fla.; and 

 September 14 at Falls Church, Va. 



This species occurs from the Atlantic States west to Michigan and 

 Kansas, from the Tropical Zone to the warmer parts of the Transi- 

 tional Zone. There is a single record from Ontario, Canada (Go Home 

 Bay). Two specimens in the U. S. National Museum were reared 

 as follows : $ , Kirkwood, Mo., August 1939, ex ootheca Parcohlatta 

 pennsylvanica; 9 , Vienna, Va., collected September 1936, emerged 

 1937, J. C. Bridwell, ex ootheca Parcohlatta sp.
