locality the species occur in the proportion usually of three scutellaris to 

 ivfo formosa and one venusta. 



C. vciiusta, Lee, usually considered a variety oi fortnosa, is claimed 

 to be a valid species by Mr. H. C. Fall, of Pasadena, California. Mr. 

 Fall bases his conclusion on habits and secondary sexual characters, and 

 is undoubtedly correct in his claim. 



I have taken it for a number of years in the sand hills near Medora, 

 associated with scutellaris ^ndfot'mosa, as noted above. It is found, how- 

 ever, much nearer the pools at the bottom of sand " blow-outs " than 

 either of these species. I also took a single specimen of vennsta on the 

 clay bluffs south of the Smoky Hill River at Wallace, Kansas, in July. 



C./«4'-/^<?, Say, is reported from Western Kansas, in the valley of 

 the Smoky Hill River, but I have only taken it along the edges of the salt 

 marsh three miles west of Kackley, in Republic County. The present 

 season I found it in numbers on July yth. The height of its season is 

 probably from June 20th to July 10th. It is taken with togata and cir- 

 cumpida, and flies more quickly, but does not run so rapidly as these 

 species. The red markings of some of the specimens had become almost 

 black. 



C. vulgaris, Say, occurs over Eastern and Central Kansas. I find it 

 in abundance in Reno County, associated sometimes with formosa and 

 scutellaris, and at other limes with repanda and hirticollis ; usually found 

 on higher and more sandy localities than repanda. 



C. repanda, Dej., is found in all parts of the State, along mud banks 

 and along the bottoms of dry pools. 



The variety 12-guttata, Dej., is found over Eastern Kansas, l:)ut not 

 so abundantly as repauda or vulgaris. 1 have taken it at Manhattan, 

 near Osage City, on mud at bottom of coal strippings in June, and the 

 present season I found a single specimen September 17th, under a stone 

 on a shallow on the Verdigris River, near Benedict, Wilson County. A. 

 W. Jones has also taken it near Salina. 



C. hirticollis, Say, is reported at Lawrence and Topeka, by Prof 

 Popenoe as common on sand bars at Topeka. I have taken it August 

 1 6th, on sand bar in Arkansas River at Dodge City. The specimens were 

 large and elytral markings wide. The present season I found it on May 

 27th, on wet bed of pools at bottom of sand "blow-outs," three miles 

 south-west of Medora. It was found only in one locality, associated with 

 vulgaris and repanda.
