The varieties noted above, which are strongly defined, are limbalis, 

 denverensis, ludoviciana, Audubonii and plutonica. Of the others, 

 transversa and graminea run more or less into purpurea, spreta is 

 hardly separated from limbalis, and lauta is doubtfully separated 

 from graminea. 



I have in my collection several unique specimens which cannot be 

 included with any of these varieties, and no doubt the reader will 

 have others, and they had best remain unnamed until a larger series 

 shows clearly where they belong. 



C cimarroiia Lee, 1868, Trans. Am. Eut. Soc. ii, p. 49; Schaupp, I. c, p. 89, 

 pi. 2, fig. 40 (this figure gives an unsatisfactory representation of the 

 marginal band and is misleading). 

 Length 13-15 mm.=.52-.60 inch. 



Habitat. — Colo, and N. Mex. 



Black above and beneath, or green, sometimes with a coppery 

 lustre, especially on the thorax and beneath ; elytral markings con 

 sisting of a marginal band, sometimes incomplete, with branches 

 indicating the usual humeral luuule, middle band and apical lunule. 

 Otherwise its characters are identical with those of purpurea. I 

 separate this species because the type of the elytral markings is rad- 

 ically different, and notwithstanding the variations in color, is con- 

 stantly preserved, thereby suggesting a form too well established to 

 be called a variety. 



Taken in New Mexico by Prof Snow ; at Garland, Colo., 8000 

 feet elevation, August 28th. Prof. Popenoe (quoted by Wickham) 

 says that it occurs singly on bare clay soils about open prairies in 

 South Park, Colorado.

 pi. 18, fig. 1 ; Schaupp, I. c, p. 90, pi. 2, fig. 41 (the middle baud in this 

 figure is not long enough). 

 Length 11-14 mm. ^.44-. 56 inch. 



Habitat. — Col. ; Cal. ; Neb. ; Mont. ; Wyom. ; Kan. ; Idaho. 



Green, above sometimes tinged with cupreous; beneath bluish 

 green ; elytra dull green margined with bright green or blue, with 

 four white dots and a suddenly bent, very long, middle band not 

 dilated at tip. The humeral and post humeral dots may be missing 

 and the middle band may be reduced to a marginal spot. Well pre- 

 served specimens are very hairy, the hairs being placed as in purpurea 

 to which this species is allied.
