gests the possibility of the race being at present under the influence 

 of some evolution process. 

 Cicindela denverensis. 



This species is represented by a single specimen taken with the 

 following species. 



Cicindela ludoviciana. 



This species appears in February and continues abundant during 

 March and April. In May the number commences to diminish, and 

 from June to September there are none. A second brood appears late 

 in September and continues until December. It is partial to red rocky 

 or gray colored soils. A certain amount of moisture in the soil seems 

 to be necessary for the development and appearance of Cicindela in 

 the imago state. Last autumn Mr. Coverdale traveled a certain road 

 four times daily (Sundays excepted) for three months. The summer 

 has been extremely hot and dry and not a single specimen of Cicindela 

 was found. During the night of October first a good rain fell, the 

 first for five months, and the next morning Mr. Coverdale found C. 

 ludoviciana, C. splendida and C. vulgaris all freshly emerged and 

 abundant, where before the rain not a single specimen was to be seen. 

 This species is closely related to C. splendida and occurs over a con- 

 siderable range at Vowell's Mill associated with it. Mr. Coverdale 

 noticed in taking them that they seemed to occur at first in colonies, 

 each form by itself. The first day of their appearance he found five 

 specimens of splendida within ten or twelve feet of one another. Then 

 he found ludoviciana only for a half mile without any splendida, then 

 a few more splendida and so on all day. But after four or five days 

 both forms occurred singly. This species is distinctly blue all over 

 and varies only in the maculation. 

 Cicindela splendida. 



Occurs with the preceding and has the same range and times of 

 appearance. It varies in the intensity of the cupreous coloring, none 

 of the specimens being as bright as more northern specimens, some 

 specimens having an almost equal mixture of red and green. It 

 varies also in the maculation, none of the specimens being heavily 

 marked and some being immaculate. 

 Cicindela vulgaris. 



This species is found from February to October, being scarce m 

 midsummer. It is very abundant but rather local in the vicinity of
