C. longilabris var. laurentii Schaupp. Taken by me at Leadville, 

 Colo., on flats west of town, July 24, 1903. I found it associated with 

 C. cimarrona, and found both species equally hard to capture. This 

 may have been partly because of the strong wind that was blowing, 

 bat my experience is that they were exceedingly wary and hard to 

 approach. I saw a single specimen of laurentii at Victor, Colo, on 

 July 31. Altitude of both localities is about 10,000 feet. 



C. obsoleta Say. Two specimens taken near Bent's Fort, Colo., 

 August 23, 1902 ; one at Las Animas two days later; one at Las Ani- 

 mas, July 13, 1903 ; two at Jja Junta, August 3 ; ten at Syracuse, 

 Kan., August 4 ; ten at the same place, August 27. Of these only 

 three showed any sign of maculation. 



C. obsoleta var. prasina Lee. Three taken at Syracuse, Kan., Au- 

 gust 4, and twenty at the same place, August 27, 1903. All immacu- 

 late except one. Associated with obsoleta, from which it does not 

 differ except in color. The flight of these two insects is quite slow, 

 but often very much prolonged. They are easy of capture, especially 

 at the moment of rising. 



C. scutellaris Say. Common on sandy soil throughout the state. 

 In the eastern half of the state the specimens have a distinct green 

 sufl:'usion near the base of the elytra, but this becomes less prominent 

 as we go westward, and is entirely lacking in specimens from beyond 

 the middle of the state. The western specimens are of the typical 

 form. Those from eastern Kansas are also very often spotted and 

 sometimes approach variety lecontei in color. A single Manhattan 

 specimen closely resembles var. rugifrons. Found in the spring 

 and fall; rare in midsummer. I have taken this species at Manhat- 

 tan, Topeka, Medora, Meade, Morland, Ellis, Junction City, Ellsworth, 

 and Grainfield, Kan.; at Superior, Benkelman, andHaigler, Neb.; also 

 at Wray, Colo. 



C. nigrocoerulea Lee. In August, 1902, I accompanied Mr. War- 

 ren Knaus to Bent's Fort, Colo., in search of this species. We found 

 it common in suitable localities at this place and also at Las Animas, 

 in the same county. We captured over a hundred specimens on the 

 trip. We found blue- black and green forms associated together and 

 pairing indiscriminately, thus proving the practical identity of nigro- 

 ccBrulea and robusta Leng. The captures were August 23-25. A few 

 days later Eugene Smiyth found two specimens of this insect just east 

 of the Colorado line, near Coolidge, Kan., thus being the first to add 

 it to the state list. In 1903 I took nine specimens at Las Animas, 

 July 13, and nearly a hundred at La Junta, August 3. At Syracuse, 

 Kan., I took five on August 4, and ten on August 27. This species is 

 found on damp soil on bare spots in pastures and in alfalfa-fields. I 

 also found it in irrigated sugar-beet fields, along the borders of alkali
