series. The first is represented by purpurea and the varieties grami- 

 nea, audubonii, cimarrona, etc. This series has usually a detached, 

 oblique middle band. They stay mostly on nearly level, open coun- 

 try, along paths and on bare spots in pastures. The other series has 

 the middle band less oblique when complete, but often short and at 

 right angles to the border of the elytron, or even lacking. It is 

 usually found on steeply sloping clay banks or along deeply washed 

 gullies. To it belong limbalis, splendida, denverensis, etc. 



C. formosa Say. I have taken this beautiful species at Topeka, 

 Manhattan, Junction City, Abilene, Ellsworth, Ellis, Grainfield, Mor- 

 land. Dodge City, Lakin, Medora, Meade, Belvidere, Englewood, and 

 other Kansas places ; at Limon, Wray, and Salida, Colo. ; at Superior, 

 Benkelman, and Haigler, Neb. Abundant in spring and fall. Speci- 

 mens from eastern and middle Kansas are usually smaller and darker 

 than they are farther west. I have seen no typical examples of var. 

 generosa from Kansas, although an occasional specimen approaches it. 



C. venusta Leo. This is regarded by both Mr. Leng and Doctor 

 Horn as a distinct species and not as a variety of the preceding. 

 While it inhabits sandy. places where the other species is also usually 

 present, the association is never a close one, and its distribution is 

 much more limited. I have taken specimens at Medora and Grain- 

 field, Kan., at Limon, Colo., and at Benkelman, Neb. I found it 

 common at Grainfield, over a limited area of grassy sand, on Septem- 

 ber 25 of the present year. 



C. fulgida Say. Occurs on the salt marshes of Kansas, and wher- 

 ever the alkali in the soil comes to the surface so as to make small, 

 bare spots. On the salt marshes it prefers the border, close to the 

 grass, in which it often seeks safety when disturbed. I have captured 

 it at Talmo, Jamestown, Belvidere, Lakin, Englewood, and Wallace, 

 Kan.; at Benkelman and Haigler, Neb.; at Wray, Robinson, and La 

 Junta, Colo. It begins to be common by the middle of May and re- 

 mains through June and July, while a few persist even longer. At 

 Robinson, Colo., near Bent's Fort, I found fresh specimens, August 23, 

 in considerable numbers. This would indicate that, as with C. pul- 

 «hra, there is sometimes a fall brood. 



C, vulgaris Say. Common throughout the state. A species sub- 

 ject to many variations in size and color. Small, bright green speci- 

 mens with faint markings are found, and in western Kansas and the 

 eastern part of Colorado a well-marked variety approaching the de- 

 scription of var. obliquata is taken. This has been distributed and 

 appears in many collections as obliquata. but Doctor Horn says that 

 it is not the true obliquata, but an undescribed variety. 



C. repanda Dej. Common everywhere in Kansas that I have col-
