accepted by the present writer rims to deserta Say in Bank's key 

 (1912a, p. 13); however, not all of the specimens determined by 

 Banks agree with the above "Neotype." (3) A specimen in the 

 Philadelphia Academy of Natural Sciences determined by Cresson 

 agrees with the one the writer calls deserta Say. (4) Unpubhshed 

 notes by S. A. Rohwer indicate he accepted Cresson's determina- 

 tions at Philadelphia as correct. (5) A male specimen determined 

 by Viereck indicates he agrees with the present writer in the form 

 accepted as deserta Say. 



In the writer's paper (1942, p. 187), he called attention to the 

 fact that C. fidvipes Cresson is the female of C. deserta Say. 



Types. — The writer is accepting the male specimen labeled "Neo- 

 type," from South Dakota, Aug. 20 [locality and year illegible], at the 

 Museum of Comparative Zoology, Harvard, no. 31,113, as authentic 

 by Banks. The original type material, which apparently has been 

 lost, is recorded from "N. West Territory, Mo., Pa." The female type 

 of C.fulvipes Cresson, from Delaware, is at the Philadelphia Academy 

 of Natural Sciences, no. 1941. 



Distribution. — Throughout the North Central and North- 

 eastern States. 



Prey record. — The Peckhams (1898) record C. deserta Say as 

 taking Conotrachelus posticatus Boheman (Curculionidae) ; however, 

 because some workers have differed in the identification of C. deserta 

 Say, this record needs verification. No other prey records have 

 been found by the writer. 



Plant record. — Aster sp. (Kansas), Eupatorium sp. (Kentucky), 

 Grindelia sp. (North Dakota), Melilotus alba (North Dakota), Poly- 

 gonum sp. (Kansas), Solidago sp. (Connecticut, Kansas, Massachu- 



FiGURES 80, 81. — Localities of: 80, C. deserta Say; 81, C. frontata frontata Say.
