and east edge of the Meadow, we took our first specimen of nevadica; 

 two other specimens were taken nearby. The next day by working 

 further down the streams, other specimens were taken, and the suc- 

 ceeding four days by following the streams southward until they 

 united into a single stream, the collecting became much better. The 

 last day's work added as many specimens as the preceding four 

 days combined. 



Nevadica keeps very close to the water's edge, and in its flight 

 will not leave the water for any distance. It frequently flies from 

 one side of the stream to the other and would sometimes light in 

 the edge of the water. They were not especially wary and were 

 netted with comparative ease. A number of specimens were taken 

 soon after transforming from pupje, as the wing covers were not 

 yet hardened nor the markings clearly defined. 



Toward the north end of the Meadow on many of the streams, 

 beaches or bars were charged with salt but lower down where the 

 salt had disappeared, nevadica was found in greater numbers, an 

 evidence that they were not confined to saline localities. 



They were usually found associated with one or more species 

 of the following: 



C. var. hccmorrhagica, var. pacifica, var. hisignata, var. chihuahua, 

 puncHilata and temiisignata. 



Concerning the status of Cicindela nevadica var. knausi, I am 

 inclined to believe knausi should have full specific standing. Knausi 

 is found in southeast Kansas (salt marsh at Fredonia, Wilson 

 County) ; Central Oklahoma (salt marsh region) and Lincoln, Neb. 

 (C. lincolniana Csy,), extreme northern limit, southwestward to Santa 

 Rosa, N. M., the extreme southwestern limit being recorded at 

 Winslow, Ariz. 



Nevadica is evidently confined to southwest Nevada and possibly 

 to isolated localities across the line westward into California. 



Knausi occurs in June and July, nevadica the latter part of July 

 and August. It is a month later in approximately the same lati- 

 tude and elevation in Kansas. 



Knausi has complete elytral markings connected with a marginal 

 white area. Nevadica has no marginal white area. The middle 

 band in only one per cent, of specimens examined being connected
