western half of the state in spring and fall, and occasionally on warm 

 days in winter. It evidently hibernates. Taken by me at Ellsworth, 

 Hays, Ellis, WaKeeney, Grainfield, Oakley, Dodge City, Meade, Good- 

 land, and Colby, Kan.; at Benkelman, Neb.; at Colorado Springs and 

 Limon, Colo. 



C. purpurea var. graminea Schaupp. Found associated with i3ur- 

 purea and audubonii, and taken on the same dates and in the same 

 localities as the latter. The specimens taken in Colorado and west- 

 ward differ much in shape from those taken further east. 



C. purj^urea var. cimarrona Lee. Taken at Leadville, Colo^ July 

 24, and at Victor, Colo., July 31, 1903. Only a few seen, associated 

 with C. laurentii. I have already spoken of my difficulty in taking 

 this species. 



C. splendida Hentz. Occurs in spring and fall and on warm days 

 in winter. I have found them in midwinter by excavating their bur- 

 rows, and have taken considerable numbers in this way. A few may 

 be found in favorable places in midsummer, so that, in a few succes- 

 sive years, one could have records of their capture in every month of 

 the year. I have collected the species at Manhattan, Topeka, Meade, 

 Hays, Wa Keeney, Colby, and at Benkelman, Neb. There are records 

 of its occurrence as far west as Denver. 



Var. amoena Lee. This variety is not really separable from splen- 

 dida in any particular but in having the full elytral markings of lim- 

 balis. About one-third of the specimens taken at Manhattan have 

 these markings and may be placed under this name, but many inter- 

 mediate varieties of marking occur. The most common form is that 

 of Leng's new variety transversa. The latter insect is, however, de- 

 scribed as a variety of purpurea, and as having the same color. The 

 fact that the markings of transversa reappear both in splendida and 

 in the closely related denverensis shows the intimate relations of the 

 whole so-called purpurea group. 



C. denverensis Casey. First taken by me at Oakley, Kan., Octo- 

 ber 28, 1901, which is also the first recorded capture in the state ; 

 however, there are specimens in the Agricultural College collection 

 which were taken in Meade county several years earlier. I took sev- 

 eral specimens at Meade, Kan., May 15, 1902, and in May, 1903, I 

 found it common at Benkelman and Haigler, Neb. I found it asso- 

 ciated with a few specimens of splendida, with which it corresponds 

 in habits. In four cases I found denverensis and splendida in copu- 

 lation, and my friend, Mr. Johnson, of the Fort Collins, Colo., Ex- 

 periment Station, has observed similar cases near Denver. I have 

 observed a few specimens that I regard as intermediate forms between 

 the two. For example, I have a denverensis with -a blue thorax. A 

 study of the habits of the purpurea group leads me to recognize two
