Sept., 1902.] I.ENG : Notes on Cicindelid.e of Louisiana. 135 



To the south of Covington approaching the lake the character of 

 the vegetation gradually changes. Palmettos begin to appear, then 

 swamp timber such as water oaks, tupelo, magnolia, hackberry and 

 cypress. In this region punctulata only occurred. The heat (June 

 15) was intense, the thermometer stood at 100° in the shade, and 

 collecting Cicindelid?e on a snow white sandbar in the blazing sun 

 was hard work. 



Tetracha Carolina. 



This species was found in a low wet seepy place beside the river, 

 running about on the wet sand, hiding under pieces of bark, rocks, 

 logs, etc. Mr. Coverdale says it may be crepuscular in habit, but it 

 is a " light sleeper" and can be found easily in the day-time by kick- 

 ing pieces of bark, etc. It was also found on Mandeville Beach, Lake 

 Pontchartrain, in the cracks of dried-out mud. Jumping on the mud 

 made the beetles run out and pouring water down the cracks produced 

 a good many. They run like a race horse and are difficult to capture. 

 They bite and scratch even in the alcohol bottle. . They also come to 

 the electric lights. 



Tetracha virginica. 



A single specimen was taken at electric lights. 



Cicindela repanda. 



This species was taken on the sandbars of the Bogue Falaya River. 



Cicindela punctulata. 



This species was taken on the upper banks of the river and at 

 various places in the woods and roads. The specimens sent are more 

 metallic than the Vowell's Mill specimens. This species was also 

 collected at electric lights. 



Cicindela tortuosa. 



This species was abundant on the sandbars of the Bogue Falaya 

 River, living on the wet sand close to the river's edge. The speci- 

 mens received are all very dark in color, but are probably stained by 

 long immersion in alcohol. 



Cicindela Wapleri. 



The capture of this species was the main object of Mr. Coverdale's 

 trip, and happily it was successfully attained. The clue was taken 

 from Professor Wickham's "Habits of N. A. Cicindelidas," where
