BIOLOGICAL PAPERS. 253 



season just ended, a careful outlook was kept for this species but no 

 representatives were discovered earlier than July 2, and the total catch 

 at Manhattan did not exceed six. I took a single specimen at Alma. 

 My observations do not confirm the statement that this insect is 

 crepuscular in its habits. It seemed to be abundant at all hours in 

 which I looked for it, which were from nine A. M, to five P. M. The 

 great majority of the specimens captured were taken between two and 

 five o'clock. The presence or absence of sunlight did not seem to 

 aflPect their numbers, and they did not hide or disappear during a sud- 

 den sliower of rain. Early in the seasgn, they were found near the 

 tops of the hills; later, farther down the slopes; and when the dry 

 August weather prevailed, they came down to the moist watercourses 

 in the valleys. 



Cicindela celeripes Lee. About a dozen years ago Professor Pope- 

 noe found this species common at Manhattan and in Clay county. 

 Since then none had been collected until the season of 1902. I 

 found the species near Junction City, on the Fort Riley military 

 reservation, on May 28, 1902, and captured twenty-five specimens. 

 They seemed to have just emerged, and were confined to a space of 

 four or five square rods. On June 6, I found them more abundant at 

 the same place and also more widely distributed. A few days after- 

 ward I found them about four miles south of Manhattan, in the sand 

 hills. They were abundant at this place and college collectors after- 

 ward captured large series. Later other localities were found and they 

 continued common during the month of July. In 1903 a few speci- 

 mens were seen east of town on May 25, but the inundation which 

 followed covered all of the localities in which this species was taken 

 in 1902 except one. I was subsequently very much surprised to find 

 the insect abundant on top of the hills southwest of Manhattan. I 

 also found a few at the side of the railroad tracks in the south part 

 of town, at a place not reached by the earlier flood. Although this 

 species cannot fly, it is very difficult to capture until one learns how 

 by actual experience. It is a very swift runner and an artful dodger. 

 I take it by placing the left hand quickly directly in its way, and as 

 it runs up over the palm, I grasp it with the thumb and first finger 

 of the right. Dr. Walther Horn has announced* the discovery of a 

 specific difference between this species and the variety cursitans. He 

 finds it in the sparse white bristles on the elytra in celeripes which are 

 lacking in cursitans. I find, however, that in looking over a large 

 series of those taken here, there are all degrees of pilosity, and in 

 about half the specimens no evidence at all of such bristles on the 

 elytra. I conclude that this character would be of no use in the de- 

 termination of any but fresh specimens.
